Also Known As: Win32.Sality.A [Computer Assoc, Virus.Win32.Sality.{a-j} [Kasp, W32.Sality.{a, b, d-l} [McAfee], W32/Sality-{A, B, E-H} [Sophos], PE_SALITY.{A, H-K} [Trend Micro]
Type: Virus
Systems Affected: Windows 2000, Windows 95, Windows 98, Windows Me, Windows NT, Windows Server 2003, Windows XP


The following instructions pertain to all current and recent Symantec antivirus products, including the Symantec AntiVirus and Norton AntiVirus product lines.

1. Disable System Restore (Windows Me/XP).
2. Update the virus definitions.
3. Restart the computer in Safe mode or Safe mode with Command Prompt.
4. Run a full system scan and delete all the files detected.
5. Remove the lines that the worm added to the System.ini file.

For specific details on each of these steps, read the following instructions.

1. To disable System Restore (Windows Me/XP)
If you are running Windows Me or Windows XP, we recommend that you temporarily turn off System Restore. Windows Me/XP uses this feature, which is enabled by default, to restore the files on your computer in case they become damaged. If a virus, worm, or Trojan infects a computer, System Restore may back up the virus, worm, or Trojan on the computer.

Windows prevents outside programs, including antivirus programs, from modifying System Restore. Therefore, antivirus programs or tools cannot remove threats in the System Restore folder. As a result, System Restore has the potential of restoring an infected file on your computer, even after you have cleaned the infected files from all the other locations.

Also, a virus scan may detect a threat in the System Restore folder even though you have removed the threat.

For instructions on how to turn off System Restore, read your Windows documentation, or one of the following articles:

* How to disable or enable Windows Me System Restore
* How to turn off or turn on Windows XP System Restore


Note: When you are completely finished with the removal procedure and are satisfied that the threat has been removed, reenable System Restore by following the instructions in the aforementioned documents.

For additional information, and an alternative to disabling Windows Me System Restore, see the Microsoft Knowledge Base article: Antivirus Tools Cannot Clean Infected Files in the _Restore Folder (Article ID: Q263455).

2. To update the virus definitions
Symantec Security Response fully tests all the virus definitions for quality assurance before they are posted to our servers. There are two ways to obtain the most recent virus definitions:

* Running LiveUpdate, which is the easiest way to obtain virus definitions:
o If you use Norton AntiVirus 2006, Symantec AntiVirus Corporate Edition 10.0, or newer products, LiveUpdate definitions are updated daily. These products include newer technology.
o If you use Norton AntiVirus 2005, Symantec AntiVirus Corporate Edition 9.0, or earlier products, LiveUpdate definitions are updated weekly. The exception is major outbreaks, when definitions are updated more often.
* Downloading the definitions using the Intelligent Updater: The Intelligent Updater virus definitions are posted daily. You should download the definitions from the Symantec Security Response Web site and manually install them. To determine whether definitions for this threat are available by the Intelligent Updater, refer to Virus Definitions (Intelligent Updater).

The latest Intelligent Updater virus definitions can be obtained here: Intelligent Updater virus definitions. For detailed instructions read the document: How to update virus definition files using the Intelligent Updater.


3. To restart the computer in Safe mode or Safe mode with Command Prompt
Follow the instructions for your operating system.

Windows 95/98/Me
Shut down the computer and turn off the power. Wait for at least 30 seconds, and then restart the computer in Safe mode. For instructions, read the document: How to start the computer in Safe Mode.

Once in Safe mode (this could take some time) proceed with the next section.

Windows 2000

1. Shut down the computer, and then turn off the power. Wait for at least 30 seconds, and then restart the computer
2. When you see the black and white Starting Windows bar at the bottom of the screen, press the F8 key (usually on the top row of the keyboard).
3. In the Windows 2000 Advanced Options Menu, select Safe mode with Command Prompt, and then press Enter.

Once the computer opens to a window with a command prompt (you should see a line of text and a blinking cursor), proceed with the next section.


Windows XP

1. Shut down the computer, and then turn off the power. Wait for at least 30 seconds, and then restart the computer. The computer begins processing a set of instructions known as the Basic Input/Output System (BIOS). What is displayed depends on the BIOS manufacturer. Some computers display a progress bar that refers to the word BIOS, while others may not display any indication that this process is occurring.
2. As soon as the BIOS has finished loading, begin tapping the F8 key on your keyboard. Continue to do so until the Windows Advanced Options menu appears. If you begin tapping the F8 key too soon, some computers will display a "keyboard error" message. To avoid this, restart the computer and try again.
3. In the Windows 2000 Advanced Options Menu, select Safe mode with Command Prompt, and then press Enter.

Once the computer opens to a window with a command prompt (you should see a line of text and a blinking cursor), proceed with the next section.


4. To scan for and delete the infected files

1. Start your Symantec antivirus program and make sure that it is configured to scan all the files.
* For Norton AntiVirus consumer products: Read the document: How to configure Norton AntiVirus to scan all files.
* For Symantec AntiVirus Enterprise products: Read the document: How to verify that a Symantec Corporate antivirus product is set to scan all files.
2. Run a full system scan.
3. If any files are detected, click Delete.


5. To remove the lines that the worm added to the System.ini file.

1. Click Start > Run.
2. Type the following:

notepad c:\windows\system.ini

and then click OK.

(Notepad opens)

Note: If Windows is installed in a different location, make the appropriate path substitution.
3. In the [TFTempCache] section of the file, look for lines similar to the following and delete them:

id=[RANDOM_NUMBER]
RtlMoveMeory=[RANDOM_NUMBER]
PING=[NUMBER]
TIME=[TIME]
4. Click File > Save.
5. Click File > Exit.

W32.HLLP.Sality Risk
Level 2: Low Discovered: June 4, 2003
Updated: February 13, 2007 12:50:41 PM
Also Known As: Win32.Sality.A [Computer Assoc, Virus.Win32.Sality.{a-j} [Kasp, W32.Sality.{a, b, d-l} [McAfee], W32/Sality-{A, B, E-H} [Sophos], PE_SALITY.{A, H-K} [Trend Micro]

W32.HLLP.Sality is a virus with keylogging and back door capabilities. It may infect executable files by prepending its code to host files.

Note: Virus definitions dated prior to January 17, 2006 may detect this threat as Backdoor.Rustok.

Discovered: June 4, 2003
Updated: February 13, 2007 12:50:41 PM
Also Known As: Win32.Sality.A [Computer Assoc, Virus.Win32.Sality.{a-j} [Kasp, W32.Sality.{a, b, d-l} [McAfee], W32/Sality-{A, B, E-H} [Sophos], PE_SALITY.{A, H-K} [Trend Micro]
Type: Virus
Systems Affected: Windows 2000, Windows 95, Windows 98, Windows Me, Windows NT, Windows Server 2003, Windows XP


When W32.HLLP.Sality is executed, it performs the following actions:

1. May drop a .dll file in the %System% or %Temp% folders. The following are some examples of the filenames:

* SYSLIB32.DLL
* OLEDSP32.DLL
* SYSDLL.DLL
* OLEMDB32.DLL

Note:
* %System% is a variable that refers to the System folder. By default this is C:\Windows\System (Windows 95/98/Me), C:\Winnt\System32 (Windows NT/2000), or C:\Windows\System32 (Windows XP).
* %Temp% is a variable that refers to the Windows temporary folder. By default, this is C:\Windows\TEMP (Windows 95/98/Me/XP) or C:\WINNT\Temp (Windows NT/2000).

2. Creates the mutex named "KUKU300a" so that only one instance of the threat runs on the compromised computer.

3. May infect executable files registered in the following registry:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

Any files infected with this virus will be detected as W32.HLLP.Sality!inf.

4. Checks the current time and may activate its payload if minutes are equal to hours and if the date is May 1st or the 10th to 12th of any month.

5. May then activate the payload, and display a message box with the following characteristics:

Title: Win32.HLLP.Kuku v[VERSION_NUMBER]
Body:
<<<<>>>>
'Copy[REMOVED]tor'

6. May add its configuration data to the file %Windir%\System.ini by appending some of the following lines to this file:

[TFTempCache]
id=[RANDOM_NUMBER]
RtlMoveMeory=[RANDOM_NUMBER]
PING=[NUMBER]
TIME=[TIME]

Note: %Windir% is a variable that refers to the Windows installation folder. By default, this is C:\Windows or C:\Winnt.

7. May test connectivity by attempting to contact the following host:

www.microsoft.com

8. Uses keylogging capabilities to gather the following information from the compromised computer:

* IP address, host name, and user names
* Sensitive computer information, such as size of memory, local disks, the Windows version, and product key
* RAS dialup accounts
* Net Share passwords
* Startup programs
* WebMoney files

9. Temporarily stores any information it gathers in the following encrypted file:

%System%\TFTempCache

10. May send this information to several email addresses located in Russia using the following SMTP server over TCP port 25:

msx.mail.ru

This email has the following characteristics:

From: CyberMazafaka@mailru.com

To: sector2007@list.ru, bespontovik@list.ru

Subject: Administrator

Attachment:
* readme.tjc
* TFTempCache.tjc

11. Contains references to the following IRC server:

rinet.msk.wenet.ru

Note: At the time of writing, code to utilize this server is not implemented.

12. Allows a remote attacker to perform various unauthorized actions on the compromised computer.

13. May infect executable files by prepending its code to the host file. However, not all the variants of this virus are able to spread in this way. Any infected files will be detected as W32.HLLP.Sality!inf.

14. May delete the files which have the following extensions when searching for files to infect:

* .vdb
* .avc
* .key

15. May also delete those file names which begin with the following strings:

Recommendations

Symantec Security Response encourages all users and administrators to adhere to the following basic security "best practices":

* Use a firewall to block all incoming connections from the Internet to services that should not be publicly available. By default, you should deny all incoming connections and only allow services you explicitly want to offer to the outside world.
* Enforce a password policy. Complex passwords make it difficult to crack password files on compromised computers. This helps to prevent or limit damage when a computer is compromised.
* Ensure that programs and users of the computer use the lowest level of privileges necessary to complete a task. When prompted for a root or UAC password, ensure that the program asking for administration-level access is a legitimate application.
* Disable AutoPlay to prevent the automatic launching of executable files on network and removable drives, and disconnect the drives when not required. If write access is not required, enable read-only mode if the option is available.
* Turn off file sharing if not needed. If file sharing is required, use ACLs and password protection to limit access. Disable anonymous access to shared folders. Grant access only to user accounts with strong passwords to folders that must be shared.
* Turn off and remove unnecessary services. By default, many operating systems install auxiliary services that are not critical. These services are avenues of attack. If they are removed, threats have less avenues of attack.
* If a threat exploits one or more network services, disable, or block access to, those services until a patch is applied.
* Always keep your patch levels up-to-date, especially on computers that host public services and are accessible through the firewall, such as HTTP, FTP, mail, and DNS services.
* Configure your email server to block or remove email that contains file attachments that are commonly used to spread threats, such as .vbs, .bat, .exe, .pif and .scr files.
* Isolate compromised computers quickly to prevent threats from spreading further. Perform a forensic analysis and restore the computers using trusted media.
* Train employees not to open attachments unless they are expecting them. Also, do not execute software that is downloaded from the Internet unless it has been scanned for viruses. Simply visiting a compromised Web site can cause infection if certain browser vulnerabilities are not patched.
* If Bluetooth is not required for mobile devices, it should be turned off. If you require its use, ensure that the device's visibility is set to "Hidden" so that it cannot be scanned by other Bluetooth devices. If device pairing must be used, ensure that all devices are set to "Unauthorized", requiring authorization for each connection request. Do not accept applications that are unsigned or sent from unknown sources.
* For further information on the terms used in this document, please refer to the Security Response glossary.

[ VAKSIN VIRUS ] - Virus Merusak sector zero dari harddisk

· 0 comments

[ VAKSIN VIRUS ] - Perusahaan software antivirus ternama, McAfee, telah menemukan virus baru yang paling merusak. Virus tersebut ditemukan pada hari Minggu (7/12) lalu dan digolongkan oleh Microsoft sebagai virus yang berbahaya, dan belum ditemukan vaksin untuk mengalahkannya. Menurut CNN, virus itu dalam beberapa jam sudah menimbulkan kepanikan di New York. Peringatan ini bahkan telah diterima oleh pegawai Microsoft sendiri. Virus tersebut akan merusak sector zero dari harddisk, yang digunakan sebagai tempat penyimpanan informasi penting.

Cara kerja virus berbahaya tersebut sebagai berikut :

* Virus ini akan terkirim secara otomatis ke semua nama dalam daftar alamat contact atau email dengan subject “Sebuah Kartu Untuk Anda, atau Une Carte Virtuelle Pour Vous, atau A Card For You atau A Virtual Card For You”.
* Ketika user membuka virus tersebut, virus akan seketika ‘membekukan’ computer sehingga penggunanya harus melakukan restart kembali. Jika user menekan tombol CTRL+ALT+DEL atau perintah untuk restart, maka virus tersebut akan langsung merusak sector zero dari harddisk, sehingga harddisk akan rusak secara permanent.

Satu hal lagi, jangan menerima contact email "pti_bout_de_chou@hotmail.com&quo t; karena alamat email tersebut adalah virus yang mematikan, dan sekaligus akan mem-format computer user secara otomatis. Jika user tidak melakukannya, namun salah seorang temannya kemudian memasukkan contact tersebut dalam daftar alamat user, maka computer user juga akan terkena virus tersebut.
