WHAT IS PORT SCAN ATTACK???

2011-02-08T23:33:00.001+08:00

Definition (from Whatis.com):-

A port scan is a series of messages sent by someone attempting to break into a computer to learn which computer network services, each associated with a "well-known" port number, the computer provides. Port scanning, a favorite approach of computer cracker, gives the assailant an idea where to probe for weaknesses. Essentially, a port scan consists of sending a message to each port, one at a time. The kind of response received indicates whether the port is used and can therefore be probed for weakness.

TYPE OF PORT SCAN:-

Linear Port Scan

A linear port scan involves scanning every port on a system. Internet Protocol ports use a 16-bit numbering system, which means a total of 65,536 ports can exist on a single IP address. A liner port scan will scan all of these ports to see which ones are open, closed or hidden.

Random Port Scan

A random port scan is similar in concept to a linear port scan. However, with a random port scan, only a specified number of random ports are scanned instead of all of the available port numbers. The reason for doing this is to speed up the scan, particularly when the attacker is scanning multiple computers in attempt to find vulnerabilities. With a random port scan, if any of the scanned ports are found to be open, the attacker will investigate that computer further.

Well-Known Service Port Scan

Many services run on established "Well-Known" ports, such as ports 25 and 110 for e-mail, 21 for FTP and 80 for the Internet. A port scan that only targets well-known ports is similar in concept to a random port scan, except the port numbers are predefined instead of random. Like a random port scan, if any of the tested ports are found to be open, the attacker will investigate the computer further.

MOST OF WEB ATTACKS

2010-12-31T23:58:00.001+08:00

1. SQL injection
SQL injection allows an attacker to execute SQL commands on the server that he is attacking.

2. Cross Site Scripting (XSS)
Cross site scripting (also referred to as XSS) is a vulnerability that allows an attacker to send malicious code (usually in the form of Javascript) to another user.
Because a browser cannot know if the script should be trusted or not, it will execute the script in the user context allowing the attacker to access any cookies or session tokens retained by the browser.
It's XSS because CSS means "Cascading Style Sheets"

3. Cross site request forgery (CSRF)
Cross-Site Request Forgeries (CSRF) are almost opposite styles of attack. Rather than exploiting the trust that a user has for a Web site, they exploit the trust that a Web site has for a user. In the case of the XSS attacks we just discussed, the user is the victim. In the case of CSRF, the user is an unknowing accomplice.

4. PHP injection
PHP code injection is a vulnerability that allows an attacker to inject custom code into the server side scripting engine. This vulnerability occurs when an attacker can control
all or part of an input string that is fed into an eval() function call. Eval will execute the argument as code.

5. PERL injection
Like PHP injection, perl injection would be the same but the differences is that you inject perl code not PHP

6. Path disclosure
Contains an error message that discloses the installation path and other data.

7. ASP injection
Like PHP or perl injection, asp injection would be the same but the differences are that you inject asp code not PHP/perl. ASP injection is possible only on windows machines running IIS

8. Source code disclosure
It is possible to read the source code of a script by using script filename as a parameter. It seems that the script includes a file which name is determined using user-supplied data. This data is not properly validated before being passed to the include function.

9. Server side includes (SSI)
Server Side Includes or SSI is an easy server-side scripting language used almost exclusively for the web. As its name implies, its primary use is including the contents of a file into another, via a Web Server. SSI is primarily used to "paste" the contents of one or more files into another.

10. Code execution
Code execution vulnerabilities occur where the output or content served from a Web application can be manipulated in such a way that it triggers server-side code execution. In some poorly written Web applications that allow users to modify server-side files (such as by posting to a message board or guestbook) it is sometimes possible to inject code in the scripting language of the application itself.

11. File inclusion
An attacker could include a remote or local file and execute commands on the server

12. Directory Traversal
Directory Traversal is a vulnerability which allows attackers to access restricted directories and execute commands outside of the web server's root directory.

13. Cross Frame scripting (XFS)
This is an attack technique used to trick a user into thinking that fake web site content is legitimate data.

14. CGI security checks
CGI security checks are used to see if the Common Gateway Interface of a site is vulnerable to old/new bugs

15. Cookie attacks
By injecting a custom HTTP header or by injecting a META tag is possible to alter the cookies stored in the browser. Attackers will normally manipulate cookie values to fraudulently authenticate themselves on a web site.

16. Http response splitting/CRLF injection
HTTP headers have the structure "Key: Value", where each line is separated by the CRLF combination. If the user input is injected into the value section without properly escaping/removing CRLF characters it is possible to alter the HTTP headers structure.
HTTP Response Splitting is a new application attack technique which enables various new attacks such as web cache poisoning, cross user defacement, hijacking pages with sensitive user information and cross-site scripting (XSS). The attacker sends a single HTTP request that forces the web server to form an output stream, which is then interpreted by the target as two HTTP responses instead of one response.

17. Buffer overflow
It is almost impossible to find today a buffer overflow in a web application but still there are some scripts that use C\C++\C# code in them

18. Format String
Format string attacks are a new class of vulnerabilities discovered around 1999, previously thought harmless. Format string attacks can be used to crash a program or to execute harmful code. The problem stems from the use of unfiltered user input as the format string parameter in certain C functions that perform formatting, such as printf()

19. Integer Overflow
In computer programming, an integer overflow is an anomalous condition which may cause a buffer overflow, resulting in a computer security risk where adjacent, valid program control data may be overwritten, permitting the execution of arbitrary, and potentially harmful code.

20. LDAP Injection
Lightweight Directory Access Protocol (LDAP) is an open-standard protocol for both querying and manipulating X.500 directory services. When a web application fails to properly sanitize user-supplied input, it is possible for an attacker to alter the construction of an LDAP statement.

21. XPath Injection
This script is possibly vulnerable to XPath Injection attacks. XPath Injection is an attack technique used to exploit web sites that construct XPath queries from user-supplied input.

22. URL redirection
This script is possibly vulnerable to URL redirection attacks. URL redirection is sometimes used as a part of phishing attacks that confuse visitors about which web site they are visiting.

23. Web Application DoS
Web application DoS (Denial of Service) is an attack that sends multiples requests with a very large size to a server.

24. Hidden field manipulation
Hidden fields are used for sending a unique value to the server that cannot be edited by the user. But if the user decides to see the html source hi will see the hidden field and he could change it

25. Authentication attacks
Authentication plays a very important role in security. We use it to identify someone by a special value, cookie, session or something like that

26. Authorization attacks
While authentication requires a unique value, authorization requests a username/password value b

27. Web pilfering/crawling
This attack is used to search a hole site or parts of it for password files, hidden fields and other sensitive information

28. Domain Hijacking
This attack is used to take over domain names

29. Google
Google attacks are based on found already web vulnerability.

Top 10 Computer Security Tips

2010-09-23T21:53:00.001+08:00

There are many tips & trick to enhance your computer security. I’ll list down 10 top computer security tips here:-

1. Buy genuine antivirus software and keep it up-to-date. You also can try Grisoft AVG Free Edition or Avira Personal Free Edition. Double-check your AV with the free, online only scanners available at Panda Software and Trendmicro.

2. Check Windows Update and Office Update regularly.

3. Install a free spyware and adware software. For example SpyBot Search & Destroy. SpyBot is also paranoid and ruthless in hunting out tracking cookies.

4. Install a personal firewall. Both SyGate and ZoneAlarm offer free versions. Turn-on your Windows Firewall.

5. Block pop-up spam messages in Windows NT, 2000, or XP by disabling the Windows Messenger service (this is unrelated to the instant messaging program). Open Control Panel > Administrative Tools > Services and you'll see Messenger. Right-click and go to Properties. Set Start-up Type to Disabled and press the Stop button. Bye-bye, spam pop-ups! Any good firewall will also stop them.

6. Use strong passwords and change them periodically. Passwords should have at least ten combination characters; use letters, numbers and have at least one symbol. Example 8eW#kMp9\j. This will make it much harder for anyone to gain access to your accounts. Beware with hidden keylogger, use virtual keyboard.

7. If you have a wireless network, turn on the security features: Use MAC filtering, enable built-in Firewall and even use WPA2 with the biggest key you can get.

8. If you're using Outlook or Outlook Express, use the current version or one with the Outlook Security Update installed. The update and current versions patch numerous vulnerabilities.

9. Join a respectable e-mail security list, such as the one found at our own Security Supersite, so that you can learn about emerging threats quickly and can take proper precautions.

10. Be skeptical of things on the Internet. Don't assume that e-mail "From:" a particular person is actually from that person until you have further reason to believe it's that person. Don't assume that an attachment is what it says it is. Don't give out your password to anyone, even if that person claims to be from "support."

What is a Trojan/worm/virus/logic bomb?

2010-09-23T17:24:00.001+08:00

Trojan:
     Remember the Trojan Horse? Bad guys hid inside it until they could get
     into the city to do their evil deed. A trojan computer program is
     similar. It is a program which does an unauthorized function, hidden
     inside an authorized program. It does something other than what it
     claims to do, usually something malicious (although not necessarily!),
     and it is intended by the author to do whatever it does. If it's not
     intentional, its called a 'bug' or, in some cases, a feature :) Some
     virus scanning programs detect some trojans. Some virus scanning
     programs don't detect any trojans. No virus scanners detect all
     trojans.
Virus:
     A virus is an independent program which reproduces itself. It may
     attach to other programs, it may create copies of itself (as in
     companion viruses). It may damage or corrupt data, change data, or
     degrade the performance of your system by utilizing resources such as
     memory or disk space. Some virus scanners detect some viruses. No
     virus scanners detect all viruses. No virus scanner can protect
     against "any and all viruses, known and unknown, now and forevermore".
Worm:
     Made famous by Robert Morris, Jr. , worms are programs which reproduce
     by copying themselves over and over, system to system, using up
     resources and sometimes slowing down the systems. They are self
     contained and use the networks to spread, in much the same way viruses
     use files to spread. Some people say the solution to viruses and worms
     is to just not have any files or networks. They are probably correct.
     We would include computers.
Logic Bomb:
     Code which will trigger a particular form of 'attack' when a
     designated condition is met. For instance, a logic bomb could delete
     all files on Dec. 5th. Unlike a virus, a logic bomb does not make
     copies of itself.

CLONEZILLA VS NORTON GHOST®

2010-08-25T22:45:00.001+08:00

For some reason, I always used Norton Ghost® to make backup and restore. Recently, I try to copy a disk-to-disk using this Norton Ghost® for the Windows 7. But I have failed. Then, I know that Norton Ghost does not support Windows 7.

After googling a few minutes, I found the OpenSource clone system (OCS) solution called Clonezilla. The advantages for these software are:

Free (GPL) software.
Supported file system:- MS windows, GNU/Linux, Intel-based Mac OS, and FreeBSD, NetBSD, and OpenBSD. Therefore you can clone any supported file system no matter it's 32-bit (x86) or 64-bit (x86-64) OS.
It does not takes a lot of time to massively clone systems to many computers. (Note: It took only about 10 minutes to clone a 5.6 GB system image to all 41 computers via multicasting!)

LINUX INTRODUCTION: FEDORA CORE

2010-04-04T17:20:00.001+08:00

Salam…Today, I wanna share a few about Linux OS…. This post created especially to whom that like free open source Operating Systems (like Fedora Linux). Sharing is caring….);

Before Linux

In 1980’s, Microsoft’s DOS was the dominated OS for PC. There have others better OS such as Apple MAC and UNIX, but both were expensive. People was looking for a UNIX based system, which is cheaper and can run on all platform PC.

Both DOS, MAC and UNIX were proprietary, for example the source code of their kernel is protected. No modification is possible without paying high license fees.

GNU project

Established in 1984 by Richard Stallman, who believes that software should be free from restrictions against copying or modification in order to make better and efficient computer programs.

Beginning of Linux

A famous professor Andrew Tanenbaum developed Minix, a simplified version of UNIX that runs on PC. But Minix is for class teaching only. No intention for commercial use

In Sept 1991, Linus Torvalds, a second year student of Computer Science at the University of Helsinki, developed the preliminary kernel of Linux, known as Linux version 0.0.1.

Nowadays, Linux has been used for many computing platforms such as PC, PDA, server, Mainframe, Supercomputer etc. There are so many types of Linux such as Red Hat Linux, Debian GNU/Linux, Mandrake Linux and so on.

FEDORA CORE

Fedora Core is free Operating Systems. New release version of Fedora was version 12.00. Fedora have some built-in software such as:

Mozilla Firefox ~ web browser.
Evolution ~ mail client and personal information manager.
OpenOffice.org Writer ~ is a word processing program.
OpenOffice.org Impress ~ is for creating and giving presentations.
OpenOffice.org Calc ~ is a spreadsheet tool.
Audio Player ~ The XMMS (X Multimedia System), which is used to play digital sound files
CD Player ~ The default CD player
Sound Juicer CD Ripper ~ Burn your own CDs
Messaging Client ~ GAIM supports AIM, MSN, ICQ, and many other popular IM networks.
gFTP ~ Useful for grabbing files through FTP (File Transfer Protocol)

PADAM VIRUS SECARA MANUAL

2010-01-31T15:06:00.009+08:00

PENGENALAN

Salam,selamat bertemu kembali... Pada ruangan kali ini, saya akan berkongsikan sedikit kaedah bagaimana untuk membuang virus secara manual.

Untuk suatu tempoh dahulu, (saya tak berapa ingat bila??), PC saya pernah mengalami masalah "Auto-Shutdown". Sebaik sahaja saya menghidupkan PC dan memasuki Windows, tidak kurang dalam 10 minit, PC saya akan di"Turn Off" secara automatik. Puas jugak saya melakukan pemeriksaan perkakasan. Saya jugak telah up-to-date antivirus saya tetapi masih tiada sebarang virus yang dapat dikesan. Tanda-tanda asas PC dijangkiti virus juga tiada. Dgn kata lain, Folder Options, Task Manager dan Registry Editor semuanya boleh dibuka dan beroperasi seperti biasa. Keseluruhan kelajuan proses jugak tidak berubah sebelum kejadian ini.

Setelah hampir berputus asa, saya sekali lagi meneliti proses yang terdapat di dalam Task Manager. Akhirnya, saya mengesyaki terdapat beberapa proses yang dicurigai telah beroperasi tanpa diduga. Proses tersebut adalah “password_viewer.exe”, “pc-off.bat” dan “olhrwef.exe”.

APA YANG PERLU DILAKUKAN???

Start PC dalam "Safe Mode", dan kemudian saya telah mematikan ( End Process) proses-proses tersebut. Seterusnya, setelah melakukan “search file” dan berjaya menemui ketiga-tiga fail tersebut, saya telah memadam (delete) fail tersebut. Dibawah merupakan “path” atau “directory” kedudukan fail-fail tersebut:

c:\windows\system 32\password_viewer.exe
c:\windows\system 32\pc-off.bat
c:\windows\system 32\olhrwef.exe

Selesai sahaja mematikan proses dan memadam fail-fail tersebut, kini langkah terakhir yang saya lakukan adalah melakukan “editing” pada “Registry Editor”. Dibawah merupakan langkah tersebut:

Pada Start Menu> klik Run dan taipkan “regedit”.
(Tetingkap Registry Editor akan terpapar)

Pergi ke:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
(Padam fail-fail tersebut yang terdapat disebelah kanan tetingkap Registry Editor)

Restart PC anda... Seharusnya PC anda akan kembali beroperasi secara normal.

( Perhatian: Jika terdapat proses-proses yang disyaki virus selain nama-nama ini, lakukan perkara yang sama keatas fail-failnya...)

Selamat Mencuba.... );

MEMBUANG BERSIH ANTIVIRUS PERCUBAAN

2010-01-15T22:00:00.007+08:00

Apabila anda membeli komputer, pernahkah anda mendapati komputer anda telah diinstall dengan perisian antivirus percubaan (trial version) yang mampu bertahan hanya untuk beberapa ketika (biasanya antara 30-90 hari tempoh percubaan). Sebagai contoh perisian antivirus percubaan McAffee ... Perisian ini pula tidak dapat "dibuang" (uninstall) secara biasa (dalam Control Panel)

Dan, masalahnya apabila anda ingin memasang/install perisian antivirus lain, contohnya Kaspersky, antivirus ini akan mengesan samada terdapat antivirus lain di dalam sistem anda. Apabila Kaspersky dapat mengesan sebagai contohnya antivirus McAffee, proses "installation" tidak dapat diteruskan selagi anda tidak "remove/uninstall" antivirus lama anda (McAffee)...

Terdapat dua kaedah untuk membuang (uninstall) antivirus lama tersebut, pertama secara manual dan kedua menggunakan "Third-Parthy Software".

Dalam kes untuk membuang perisian antivirus McAffee, anda boleh menggunakan perisian McAffee Remover Tools. Perisian ini sangat mudah dan cepat digunakan, hanya dwi-klik dan secara automatik, perisian ini akan membuang antivirus tersebut. Apabila anda menghidupkan semula komputer (restart), anda boleh memasang perisian antivirus lain (contohnya Kaspersky tadi) tanpa apa-apa masalah. Terdapat berbagai-bagai "Antivirus Remover Tools" yang boleh di dapati di google, contohnya AVG Remover Tools. Disini saya hanya memberikan dua link untuk perisian tersebut.

1. Muatturun "McAffee Remover Tools."
2. Muatturun "AVG Remover Tools."
3. Muatturun "Norton Remover Tools"

PENYELESAIAN PAPARAN "BOOTMGR is missing"

2009-11-13T16:31:00.008+08:00

Pernahkah anda mengalami paparan "BOOTMGR is missing, Press Ctrl+Alt+Del to restart" semasa menghidupkan komputer anda? Dibawah akan saya terangkan langkah-langkah untuk menyelesaikan masalah ini.

KAEDAH PERTAMA

Masukkan DVD Vista kedalam pemacu DVD anda.
Restart komputer anda.
Tetapkan komputer supaya boot pemacu DVD tersebut (di dalam BIOS setup).

Seterusnya, Vista akan meminta untuk memilih "language and keyboard layout". Abaikannya dan klik pada "Next". Seterusnya, pilih "Repair" dan "System Recovery Tool" untuk Vista akan terpapar seperti dalam gambar dibawah:

Pilih "Startup Repair" dan biarkan proses ini seketika. Jika selepas komputer direstart tetapi masih mengalami masalah yang sama, anda boleh memilih kaedah kedua ini.

KAEDAH KEDUA

Masukkan DVD Vista kedalam pemacu DVD anda.
Restart komputer anda.
Tetapkan komputer supaya boot pemacu DVD tersebut (di dalam BIOS setup).

Klik pada "Command Prompt". Paparan Command Prompt akan terhasil.
Taip "bootrec /rebuildbcd" dan tekan "ENTER".

Jika Bootrec berjaya dilaksanakan, ia akan memaparkan kedudukan instalasi Windows. Untuk menambah kepada simpanan BCD, taip "Yes" . Mesej Pengesahan akan terpapar yang mengesahkan entri tersebut berjaya dittambah.

Jika Bootrec tidak dapat mengesan sebarang kehilangan instalasi Windows, anda mesti membuang simpanan BCD,dan mesti membuatnya (re-create) semula. Gunakan araha dibawah untuk membuat simpanan BCD semula:

bcdedit /export C:\BCD_Backup. Tekan "Enter".
ren c:\boot\bcd bcd.old. Tekan "Enter".
bootrec /rebuildbcd. Tekan "Enter".
Restart the computer.

Selamat Mencuba.

ATASI MASALAH "WINDOWS GENUINE ADVANTAGE..."

2009-09-07T11:03:00.010+08:00

PENERANGAN

Pernahkah anda mendapat paparan seperti diatas ketika menghidupkan komputer Sebenarnya, punca terjadinya paparan seperti diatas adalah disebabkan anda menggunakan perisian Windows versi cetak rompak. Dan selepas pemasangan, servis untuk "Automatic Updates" tidak dikonfigurasikan untuk "Turn Off". Jadi, jika komputer anda mempunyai rangkaian internet, secara otomatik Windows akan memuatturun "patches" (dan lain-lain fail) untuk mengemaskini Windows anda. Disebabkan anda menggunakan perisian Windows versi cetak rompak, komputer pelayan (server) syarikat Microsoft akan mengesan perkara tersebut semasa proses muatturun tadi. Kesannya, syarikat Microsoft akan "menyenaraihitamkan" komputer anda dan paparan seperti diatas akan didapati secara otomatik.

PENYELESAIAN

Sebenarnya, terdapat beberapa kaedah untuk menyelesaikan masalah tersebut. Umumnya, ia dapat dibahagikan kepada dua kaedah iaitu secara manual (memadam fail-fail tertentu) secara sendiri dan secara menggunakan perisian tertentu untuk memadamkan fail-fail tersebut secara otomatik.
Untuk tutorial ini, saya akan menerangkan kaedah yang kedua menggunakan perisian yang terdapat dalam Hiren Boot CD 10.1. Muatturun Hiren Boot CD 10.1 disini.

1. Masukkan Hiren Boot CD 10.1. Selepas beberapa ketika, paparan seperti
dibawah akan muncul:

2. Seterusnya, klik pada Menu>Tweakers>RemoveWGA seperti dalam gambar dibawah:

3. Selepas beberapa saat, anda akan diminta untuk “restart” komputer anda.
4. Apabila anda selesai menghidupkan semula komputer, paparan dibawah pula akan terhasil:

5. Akhirnya, masalah tersebut telah berjaya diatasi dan tiada paparan yang berkaitan masalah "WINDOWS GENUINE ADVANTAGE..." lagi pada paparan komputer anda.

LOG-IN SEBAGAI ROOT DALAM UBUNTU

2009-09-02T14:45:00.009+08:00

PENGENALAN

Apabila anda selesai memformat cakera keras anda dengan O.S. Linux versi Ubuntu 8.10, anda akan log-in (masuk) ke dalam sistem menerusi pengguna biasa (End User). Nama untuk akaun pengguna biasa ini adalah bergantung kepada nama yang telah anda berikan semasa proses format tadi. Adalah penting dan menjadi suatu kemestian pada anda untuk log-in sebagai root (admin) jika anda ingin melakukan sesuatu konfigurasi (install servis, update dll). Ini kerana akaun root mempunyai Full Access Control manakala akaun pengguna biasa adalah terbatas.

Artikel kali ini akan menerangkan cara-cara untuk log-in sebagai root.

TUKAR KEPADA ROOT

Selepas anda log-in sebagai akaun pengguna, buka terminal dan taip arahan dibawah:

sudo passwd root (tekan button enter)
(Taipkan password yang diminta-Lihat gambar dibawah)

sudo gedit /etc/gdm/gdm.config (tekan button enter)
(Tekan kekunci Ctrl + F dan taipkan "AllowRoot=False". Tekan enter-Lihat gambar dibawah)

Tukarkan "AllowRoot=False" kepada "AllowRoot=True" dan save. Restart PC anda.
Lihat gambar dibawah.

Apabila komputer anda telah direstart, masukkan username sebagai "root" dan katalaluan yang telah anda taipkan tadi.

Kini anda telah berjaya log-in sebagai root (admin) dan anda bebas untuk melakukan apa sahaja setting/configuration. Selamat mencuba.

BAIKPULIH REGISTRY WINDOWS ANDA

2009-09-02T10:37:00.013+08:00

Sebenarnya, masalah kerosakkan sistem yang diakibatkan oleh virus dalam platform Windows XP seringkali berlaku. Antara contoh-contoh kesan biasa yang diakibatkan oleh kerosakkan ini termasuklah kehilangan fungsi Task Manager, Registry Editor, Folder Options dan sebagainya. Sila baca artikel VIRUS untuk mengetahui lebih lanjut tentang serangan virus ini.

Dalam artikel “FOLDER OPTIONS”, “TASK MANAGER” DAN “REGISTRY EDITOR” TIBA-TIBA “HILANG” ATAU “DISABLE”, saya ada menerangkan tentang kaedah baikpulih Folder Options dan Task Manager. Dalam artikel ini pula, saya akan menerangkan cara-cara membaikpulih fungsi Registry Editor Windows anda.

Sebenarnya untuk menjalankan (lunch) fungsi Registry Editor, terdapat beberapa cara dan antara yang paling popular adalah dengan Run. Pergi ke start-> Run -> Taip "regedit" dan tekan enter. Seharusnya paparan Registry Editor akan terhasil, tetapi jika terdapat kerosakkan sistem, paparan berikut akan terhasil:

“Registry editing has been disabled by your administrator”

Sebelum pergi dengan lebih jauh, lebih baik pembaca mengetahui sedikit sebanyak tentang Registry ini. Registry Editor, juga disebut sebagai Windows Registry merupakan pangkalan data yang menyimpan semua setting tentang Microsoft Windows Operating System. Antara setting yang disimpan termasuklah informasi dan setting untuk perkakasan, perisian O.S., kebanyakkan perisian bukan O.S (non-O.S. system software) dan sebagainya.

Penyelesaiannya, anda boleh menggunakan salah satu dari pilihan dibawah:

Group Policy

Start-> Run, taip "gpedit.msc" dan tekan Enter.

Pergi ke User Configuration\Administrative Templates\System.

Dwi-klik pada Prevent access to registry editing tools.

Tukarkan nilainya kepada Disabled.

Third-Party Registry Editor

Anda boleh menggunakan perisian yang boleh akses registry, selain dari regedit. (Cth: Tuneup Utilities)

Pergi ke

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System

Cari DisableRegistryTools dan tukarkannya kepada 0.

MAC SPOOFING (Siri 1)

2009-08-30T14:26:00.017+08:00

PENGENALAN

Di dalam sesuatu sistem rangkaian, terdapat beberapa cara untuk menentukan identiti antara sesuatu host. Antaranya termasuklah alamat IP (Internet Protocol Address/ IP Address), nama komputer (Computer Name) dan juga MAC address. MAC address juga kadang-kala disebut Ethernet address, physical address, atau hardware address.

Secara dasarnya, hanya IP address dan Computer Name yang biasa diubah oleh pengguna. Jarang sekali pengguna membuat penukaran MAC address pada komputer mereka. Artikel kali ini akan menerangkan cara-cara untuk menukar MAC address komputer anda.

MENGAPA TUKAR MAC ADDRESS

MAC Address merupakan singkatan Media Access Control Address. MAC address merupakan pengenal unik yang digunakan untuk kebanyakkan network adapters/ network interface cards (NICs) oleh pengeluar untuk tujuan pengenalan (identification). Penukaran MAC Address juga disebut sebagai MAC spoofing.

Penukaran MAC Address akan membenarkan pemintasan access control lists di dalam servers atau routers sama ada menyembunyikan komputer di dalam rangkaian (network) ataupun menyamar sebagai komputer lain. Dengan kata lain, “MAC spoofing” adalah aktiviti mengubah MAC address sesuatu network card.

MENUKAR MAC ADDRESS

Terdapat tiga (3) kaedah yang utama untuk melakukan MAC spoofing atau mengubah MAC address ini. Pertama adalah dengan mengubah setting pada control panel, kedua pada Windows Registry dan terakhir menggunakan perisian MAC changer seperti SMAC tool. Sebelum anda melakukan penukaran ini, anda perlulah menulis MAC address NIC anda yang asal (sebagai langkah berjaga-jaga).

Dalam artikel ini, saya akan menerangkan kaedah pertama. Insya’allah, kaedah kedua dan ketiga akan muncul dalam artikel akan datang.

Kaedah Pertama: Setting Pada Control Panel

Kaedah ini bergantung kepada jenis NIC (Kad Rangkaian) yang komputer anda gunakan. Jika anda menggunakan NIC yang tidak menyokong (support) “clone MAC address”, anda boleh ke kaedah kedua.

Berikut merupakan langkah-langkah untuk kaedah ini:

Pergi ke Start->Settings->Control Panel dan dwi-klik pada Network Connections. Pastikan Control Panel anda berada dalam paparan klasik (klik pada Switch to Classic View- disebelah kiri). Lihat gambar dibawah.

Klik kanan pada NIC yang anda ingin tukarkan MAC addressnya. Klik pada properties. Lihat gambar dibawah.

Dibawah tab “General”, klik pada “Configure” button.

Paparan dibawah akan terhasil mengikut jenis NIC anda.

Kilk pada tab “Advanced”. Lihat gambar dibawah.

Dibawah seksion “Property”, anda akan melihat item “Network Address” atau "Locally Administered Address". Klik pada item ini. Jika tiada, bermakna NIC anda tidak support untuk proses “clone MAC address” ini.

Pada bahagian kanan, dibawah “Value”, taip nombor MAC address baru yang anda ingini untuk NIC anda. Lihat gambar dibawah.

Untuk memeriksa samada anda berjaya mengubah MAC address anda, pergi ke “command prompt” dan taip “ipconfig /all”. Jika tiada sebarang perubahan, anda perlu menggunakan kaedah kedua.

Jika berjaya, reboot komputer anda.

CARA-CARA INSTALL UBUNTU 8.04 (Siri 2)

2009-08-28T09:09:00.014+08:00

Artikel kali ini adalah sambungan untuk artikel bertajuk:
CARA-CARA INSTALL UBUNTU 8.04 (Siri 1)

Seterusnya, pada paparan "Prepare Disk Space", pilih "Guided - use entire disk". Pilihan ini adalah untuk melakukan pemasangan OS tersebut pada seluruh cakera keras. Pilihan "Manual" pula adalah untuk melakukan konfigurasi pemasangan secara manual. Contoh konfigurasi yang boleh dibuat secara manual adalah seperti jumlah pembahagian cakera keras, File System (Contoh: Ext3, Fat32 etc) cakera keras dan sebagainya. Pilihan ini biasanya adalah untuk mereka yang telah biasa (intermediate) dengan instalasi Linux. Klik "forward" sehingga keluar paparan "Ready to Install", klik pada "Install". Lihat gambar-gambar dibawah:

Masukkan "username", "password", dan "machine name". Untuk contoh ini, saya menggunakan "username" sebagai "dgadmin", dan "machine name" sebagai "dgserver".

Untuk pengetahuan para pembaca, jika anda melakukan instalasi ini dengan mempunyai sambungan internet, maka kebanyakkan servis di dalam versi ini (Ubuntu 8.04) akan dikemaskini secara langsung (auto-update) dari server pengeluar Linux. Walaupun perkara ini adalah bagus untuk sistem anda secara keseluruhannya, tetapi ini akan memperlambatkan proses instalasi (mungkin akan mengambil masa beberapa jam). Oleh itu, pilihan yang terbaik adalah anda perlu memastikan tiada sambungan internet ketika proses instalasi sedang berjalan. Anda boleh melakukan kemaskini servis secara manual selepas proses ini selesai nanti.

Akhir sekali, selepas beberapa ketika, paparan "Installation complete" akan terhasil. Anda perlu klik pada butang (button) "Restart now". Komputer anda akan direstart dan anda perlu mengeluarkan cd dari cd-drive anda ketika diminta berbuat demikian.

Selepas komputer anda dihidupkan, masukkan "username" dan "password" yang telah dibuat sebentar tadi.

CARA-CARA INSTALL UBUNTU 8.04 (Siri 1)

2009-08-27T08:52:00.012+08:00

PENGENALAN

Linux merupakan Sistem Pengoperasian (Operating System/ OS) yang banyak sekali digunakan pada komputer jenis pelayan (Server). Salah satu yang paling terkenal adalah Google Corp. yang mana semua komputer pelayannya menggunakan Linux versi Ubuntu.

Linux berbeza dengan OS keluaran Microsoft Corp. dari beberapa segi, antaranya Linux adalah OS yang berasaskan Open-Source (Sumber Terbuka) manakala Microsoft Windows pula berasaskan Closed-Source (Sumber Tertutup). Kebanyakkan versi Linux (kecuali versi Red Hat etc.) adalah lesen percuma (Freeware License-GNU/GPL) manakala Microsoft adalah lesen berbayar.

Oleh sebab Linux adalah Sistem Pengoperasian Sumber Terbuka (Open Source Code Operating System), maka pengguna dapat mengubah kod serta mengkonfigurasi sistem mengikut keperluan penggguna. Ini akan sekaligus meningkatkan tahap keselamatan sesuatu sistem yang berasaskan OS Linux. Perkara yang sama tidak akan berlaku pada sistem yang menggunakan OS versi Microsoft kerana ianya adalah jenis Sistem Pengoperasian Sumber Tertutup (Close Source Code Operating System).

Artikel kali ini akan saya terangkan tentang cara-cara melakukan pemasangan (installation) Linux versi Ubuntu 8.04 ( Hardy Heron).

PERKONGSIAN FAIL ANTARA WINDOWS DAN LINUX

2009-08-21T22:06:00.017+08:00

PENGENALAN

Di dalam sesuatu sistem rangkaian, perkongsian fail (File sharing) adalah sesuatu yang biasa dan tidak asing dilakukan oleh sesiapa jua samada pengguna host mahupun server. Untuk melakukan perkongsian data di dalam sesuatu sistem rangkaian (L.A.N) yang menggunakan O.S. yang sama (contohnya: Windows XP), settingnya adalah amat mudah bagi kebanyakkan pengguna biasa (End User). Walaubagaimanapun, melakukan perkongsian data menggunakan O.S. yang berbeza (contohnya: Linux dan Windows) adalah sesuatu yang asing bagi kebanyakkan dari pengguna yang “dibesarkan” dengan platform Windows.

PERKARA PERTAMA YANG PERLU DIBUAT...

Sudah semestinya, apabila anda ingin membuat perkongsian data, anda perlu mengenalpasti dahulu apa yang ingin dikongsikan di dalam rangkaian anda. Untuk host yang platformnya Windows, settingnya adalah sama (seperti membuat file sharing antara Windows- Windows). Yang perlu dibuat setting (enable/install service) adalah dari platform Linux. Di dalam tutorial ini, saya akan menerangkan cara-cara setting (enable/install service) bagi platform Linux Ubuntu 8.10 (Intrepid Ibex). Servis untuk perkongsian fail di dalam Linux ini dikenali sebagai Samba Service.

Muatturun Linux Ubuntu 8.10 disini.

LANGKAH SETERUSNYA...

Kenalpasti mana data/folder yang ingin dikongsikan di dalam rangkaian.

Right-click pada folder tadi, pilih Sharing Options. Lihat gambar dibawah.

Kekotak Folder Sharing akan muncul. Tik pada “Share this folder” > “install services”. Lihat gambar dibawah.

Masukkan katalaluan host/pc anda.

Seterusnya, proses memuatturun paket servis Samba (Samba service package) akan bermula. Anda perlukan sambungan internet untuk proses ini.

Tunggu hingga proses muatturun dan instalasi selesai. Lihat gambar dibawah.

Restart session.

Selepas komputer dihidupkan, ulangi langkah 2. Tik pada kekotak “Share this folder” dan seterusnya klik pada butang “Create Share”. Lihat gambar dibawah.

Akhirnya, folder tersebut telah pun berjaya dikongsikan didalam rangkaian dan boleh di”akses” oleh host yang berplatform Windows tadi.

PARTIMAGE IS NOT GHOST (PING)-BAH. 2

2009-08-12T10:47:00.010+08:00

Pada artikel kali ini, saya akan menerangkan cara-cara untuk "burn" fail Ping.iso. Kepada sesiapa yang tidak mempunyai fail Ping.iso ini, bolehlah memuatturunnya disini.

CARA-CARA BURN FAIL PING.ISO :

Burn boleh dilakukan dengan menggunakan perisian kegemaran ramai seperti Nero. Berikut merupakan langkah-langkahnya:

Buka Nero Burning Rom

Pilih Recorder / Burn Image

Browse pada PING.a.bc.iso (a.bc merupakan versi perisian ini)

Jika anda tidak mempunyai sebarang tool untuk burn fail ISO ini:

Layari Alex Feinman's website dan muatturun perisian IsoRecorder. Ianya adalah freeware, dan mengikut pengalaman saya, ianya beroperasi lebih baik dari sebarang perisian burning yang lain. Install perisian ini.

Selepas itu, buka folder yang mengandungi fail ping.a.bc.iso, right-click pada fail ISO ini , dan pilih "Copy Image to CD". (anda perlu memasukkan cdr dalam dvd writer anda dahulu.)

PARTIMAGE IS NOT GHOST (PING)-BAH. 1

2009-08-11T10:45:00.007+08:00

PING (Partimage Is Not Ghost) merupakan pilihan yang tepat untuk membuat “backup and restore” seluruh partition.

Perisian ini menyokong (support) perkakasan menggunakan ATA, SATA, atau sistem SCSI untuk komputer desktop, workstations, dan server.

Perisian ini juga mampu mengakses sistem fail seperti FAT16, FAT32, NTFS atau ext3 format.

Cara yang mudah untuk membuat backup iaitu menggunakan DVD atau Network.

Altenatif kepada Symantec Ghost, tetapi mempunyai ciri-ciri yang lebih mudah dan baik serta ianya percuma (tanpa lesen).

Merupakan perisian percuma Linux berdasarkan live CD ISO.

Dibangunkan oleh SysAngel dan versi terkininya adalah 3.00.03 (1 Aug 2009).

Dibawah merupakan perbandingan antara perisian Symantec Ghost dan PING:-

Masa untuk proses backup/restore adalah lebih pantas jika menggunakan GHOST.

PING pula mampu memadatkan fail backup jauh lebih kecil berbanding Ghost.

Sekian saja maklumat untuk perisian PING ini, artikel yang akan datang akan membincangkan berkenaan cara penggunaan perisian ini.

KAWAL PC LAIN MENGGUNAKAN TEAMVIEWER

2009-08-05T23:42:00.011+08:00

PENGENALAN

Pernahkah anda mengalami situasi seperti dibawah:

Memerlukan bantuan sahabat anda yang mahir komputer untuk membaiki komputer anda, tetapi sahabat anda itu berada jauh beberapa batu (atau lebih) dari anda (sahabat anda tersebut pula agak mustahil untuk membaiki komputer anda dengan serta merta)?
Diperlukan oleh sahabat anda untuk membaiki komputer mereka, tetapi anda/mereka pula berada jauh dari anda (yang tidak memungkinkan anda untuk datang membantu)?
Apakah altenatif anda? Adakah anda perlu menghantar pc atau menyuruh sahabat anda menghantar pc tersebut ke kedai komputer???

Jawapannya TIDAK!! Dengan bantuan perisian TeamViewer (dan perlu sambungan internet), anda dapat meminta/memberikan bantuan dari jarak jauh!!!!!

APA YANG PERLU DILAKUKAN?

Muatturun perisian TeamViewer
Pasang (install) pada kedua-dua PC. PC anda dan rakan anda.
Kedua-dua PC akan mempunyai ID dan password.
Jika anda ingin menghubungkan pc anda dengan pc rakan, kedua-kedua pc haruslah menjalankan (launch) perisian ini.
Anda perlu memasukkan id dan password rakan anda untuk membolehkan pc anda berhubung dan seterusnya dapat mengawal pc rakan anda tersebut.
Masukkan nombor dan password tersebut pada pc anda dan klik pada butang “connect to partner”.
Akhirnya, anda dah boleh lihat dan kawal pc rakan anda. Jika sudah habis, tutup sahaja perisian Teamviewer ini untuk menamatkan sesi.
Sebenarnya terdapat keistimewaan lain pada perisian ini iaitu ia boleh digunakan untuk bertukar-tukar fail, chat, dan banyak lagi.
Sebenarnya, terdapat perisian terbina-dalam (built-in software) pada Windows XP yang sinonim dengan perisian ini, iaitu Remote Assistance.
Anda juga boleh melakukan "remote computer" secara online menggunakan laman web logmein.

PERHATIAN

Teamviewer ni digunakan untuk memberikan bantuan kepada komputer kawan, bukannya untuk tujuan menceroboh dan apa-apa sahaja tujuan lain yang berniat jahat...

ROUTER (PENGHALA)-BAH. 1

2009-08-05T15:20:00.008+08:00

Berfungi untuk menghala dan menghantar (routing & sending) paket-paket data di dalam sesuatu rangkaian.

Biasanya menjalankan sistem pengendalian tersendiri.

Router biasanya digunakan untuk menghubungkan 2 atau lebih "network segment" di dalam sesuatu rangkaian. Juga bertindak sebagai Gateway untuk sambungan pada internet.

"Routing is a concept, not product". Jadi, kita boleh juga konfigurkan PC biasa menjadi router. Kita perlu memasang 2 atau lebih NIC untuk membolehkan PC biasa bertindak sebagai router.

Dengan perisian yang sesuai (seperti SmoothWall, XORP atau Quagga), PC biasa juga tidak mustahil boleh bertindak sebagai router.
Terdapat berbagai-bagai jenis dan jenama router di dalam dunia ini. Antara jenama yang paling terkenal adalah Cisco router.

TUTORIAL INI HANYA UNTUK TUJUAN PEMBELAJARAN SAHAJA.

(THIS TUTORIAL IS FOR EDUCATIONAL PURPOSE ONLY)

Secara teori, wireless menyiarkan (broadcast) mesej melalui gelombang radio.
WEP= Wired Equivalent Privacy (WEP) diperkenalkan pd 1997, merupakan sejenis algoritma yg digunakan untuk melindungi rangkaian wireless IEEE 802.11.
Beberapa kelemahan dikenalpasti pada tahun 2001 & didapati WEP dapat ditembusi menggunakan perisian tertentu dalam masa hanya beberapa minit sahaja!...
Sebenarnya, WEP merupakan algoritma pertama yang digunakan bagi konfigurasi "Acces Point" (router), dan sehingga kini masih ramai pengguna yg masih menggunakan teknologi ini.
Beberapa perisian yg dianggap berkesan dalam mendapatkan katalaluan (password) bagi wireless yg menggunakan WEP adalah seperti:

Aircrack
Kismet
Lain-lain perisian

Bagi mendapatkan katalaluan wireless, konsepnya adalah sama dengan "sniffer" (sila baca artikel: SNIFFER TOOLS).
Artikel ini akan membincangkan cara untuk mendapatkan katalaluan (password) bagi wireless yg menggunakan WEP.

PERKARA PERTAMA SEBELUM ANDA BERMULA!!!!

Dalam tutorial ini, kita akan menggunakan perisian Aircrack yang terdapat di dalam CD Back Track 4.( Muatturun Back Tra ck 4).
Anda juga perlu mempunyai laptop (atau PC) yang boleh menangkap (capture) gelombang wireless dari "Acces Point/Wireless Router" yang hendak diketahui passwordnya.

MULAKAN....

Masukkan CD Back Track 4 anda, dan biarkannya proses (boot) beberapa ketika. Prosesnya adalah dalam keadaan console atau terminal. (seperti Command Prompt dalam Windows)
Selepas proses terhenti, masukkan arahan startx seperti dibawah:

root@bt:~#startx

(Arahan ini adalah untuk memulakan Back Track dalam keadaan GUI)

Selepas telah memasuki Antaramuka pengguna (GUI), buka Terminal (Shell Konsole) seperti yang terdapat dalam rajah dibawah:-

SETERUSNYA...

Untuk menyenaraikan semua “wireless interface”, taipkan arahan ini iwconfig
Bagi kenalpasti mana “wireless interface” y g aktif, taipkan arahan ini ifconfig.
Untuk kenalpasti chipset & driver yg digunakan, taip: airmon-ng (Lihat gambar)
Untuk aktifkan interface,taipkan: airmon-ng start wlan0 (Lihat gambar dibawah)

5. Senaraikan semua wireless router & client’s MAC address: airodump-ng wlan0

6. Pilih spesifik encryption: airodump-ng –bssid -c -w

7. To generate traffic: aireplay-ng -1 0 –a

8. To generate traffic: aireplay-ng -3 –b

9. To generate traffic : aircrack-ng .cap

10. Selesai (key found)…..

KEYLOGGER

2009-07-27T11:05:00.016+08:00

Fungsi utama= Merekod "keystroke" (apa yg ditekan) dari papan kekunci.

Biasanya, keylogger akan menyimpan segala karakter (huruf, nombor, simbol) yg. ditekan pada papan kekunci dan disimpan dalam suatu senarai (log).

Terdapat beberapa keylogger yg mempunyai fungsi tambahan seperti:

"Screen capture",
"Program activity",
"Print activity".
“Web page” yang dilayari.
Sesetengah keylogger dapat menghantar log melalui email.

Terdapat dua jenis keylogger iaitu:

Hardware Keylogger (besarnya seukuran bateri ukuran AA. Keylogger jenis ini dipasangkan pada hujung keyboard).
Software Keylogger (di"install" secara sembunyi dalam sistem computer.

Keylogger boleh disalahgunakan untuk pelbagai tujuan jahat, antaranya mencuri "Username" dan "password", tugasan, dll.

Antara contoh perisian keylogger termasuklah:

Elite keylogger (Muatturun Elite Keylogger)
Refog (Muatturun Refog)
Perfect Keylogger
Actual Spy
Undetectable Keylogger
KGB Keylogger etc.(Muatturun KGB Keylogger)

Bagaimana untuk menghindari dari direkod oleh keylogger??? Berikut adalah caranya:

Virtual Keyboard (Muatturun)
Lain-lain perisian keylogger
Menggunakan "Strong password", kombinasi dari huruf kecil, besar, nombor, simbol dan lebih dari 12 karakter.
"Copy and paste" sebahagian karakter (huruf, simbol dll) dan taip sebahagian yg lain untuk perkara yg penting seperti "username" dan "password".
