W32.Sality.AE is a virus that spreads by infecting executable files and attempts to download potentially malicious files from the Internet.

Autorun and W32.Sality
Symantec strongly recommends that customers take specific steps to control the execution of applications referenced in autorun.inf files that may be located on removable and network drives. Threats such as this one frequently attempt to spread to other computers using these avenues. Configuration changes made to a computer can limit the possibility of new threats compromising it. For more information, see the following document:

How to prevent a virus from spreading using the "AutoRun" feature

Virus definitions dated April 20, 2008 or earlier detect this threat as W32.Bacalid!inf .

Symantec Endpoint Protection – Application and Device Control
Symantec Security Response has developed an Application and Device Control (ADC) Policy for Symantec Endpoint Protection to protect against the activities associated with this threat. ADC policies are useful in reducing the risk of a threat infecting a computer, the unintentional removal of data, and to restrict the programs that are run on a computer.

This particular ADC policy can be used to help combat an outbreak of this threat by slowing down or eliminating its ability to spread from one computer to another. If you are experiencing an outbreak of this threat in your network, please download the policy .

To use the policy, import the .dat file into your Symantec Endpoint Protection Manager. When distributing it to client computers, we recommend using it in Test (log only) mode initially in order to determine the possible impacts of the policy on normal network/computer usage. After observing the policy for a period of time, and determining the possible consequences of enabling it in your environment, deploy the policy in Production mode to enable active protection.

For more information on ADC and how to manage and deploy them throughout your organization, please refer to the Symantec Endpoint Protection Administration Manual (PDF).

Note: The ADC policies developed by Security Response are recommended for use in outbreak situations. While useful in such situations, due to their restrictive nature they may cause disruptions to normal business activities.

Type: Virus
Infection Length: 57,344 bytes
Systems Affected: Windows

When the virus is executed, it copies itself as the following file:
%System%\drivers\[RANDOM NAME].sys

The virus creates the following mutex so only one instance of the virus is running:
Op1mutx9

It then creates the following registry subkeys:

  • HKEY_CURRENT_USER\Software\[USER NAME]914
  • HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\Root\LEGACY_WMI_MFC_TPSHOKER_80
  • HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\Root\LEGACY_IPFILTERDRIVER

It then creates the following registry entry so that it bypasses the Windows Firewall:
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\SharedAccess\Parameters\FirewallPolicy\StandardProfile\AuthorizedApplications\List\"[INFECTED FILE]" = "[INFECTED FILE]:*:Enabled:ipsec"

It modifies the following registry entries:
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Setting\"GlobalUserOffline" = "0"
  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\system\"EnableLUA" = "0"

The virus also deletes entries under the following registry subkeys:
  • HKEY_CURRENT_USER\System\CurrentControlSet\Control\SafeBoot
  • HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SafeBoot
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Ext\Stats
  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Ext\Stats
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Ext\Stats
  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Ext\Stats
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects
  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects

It then registers itself as a new service with the following characteristics:
Service Name: WMI_MFC_TPSHOKER_80
Display Name: WMI_MFC_TPSHOKER_80
Startup Type: Automatic

It then deletes the following file:
%System%\drivers\[RANDOM NAME].sys

It adds the following entry to %Windir%\system.ini:
[MCIDRV_VER]

It then copies itself to attached removable drives using the following filenames:
%DriveLetter%:\[RANDOM NAME].exe
%DriveLetter%:\[RANDOM NAME].cmd
%DriveLetter%:\[RANDOM NAME].pif

The following file is created on attached removable drives so that the threat runs whenever the drive is connected to a computer:
%DriveLetter%:\autorun.inf

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.
