Type: Worm
Infection Length: 265,728 bytes
Systems Affected: Windows

When the worm is executed, it copies itself as the following files:

  • %System%\winlogin.exe
  • %UserProfile%\Application Data\EZSpammer.exe

The worm then creates the following file:
%UserProfile%\Application Data\data.dat

The worm then creates the following registry entries so that it runs every time Windows starts:
  • HKEY_CURRENT_USER\Software\Microsoft\Active Setup\Installed Components\{AB68ADAA-71EF-4CDD-BFFF-CEC31F5A92EB}\"StubPath" = "%UserProfile%\Application Data\EZSpammer.exe"
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run\"winlogin" = "%UserProfile%\Application Data\EZSpammer.exe"
  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Active Setup\Installed Components\{AB68ADAA-71EF-4CDD-BFFF-CEC31F5A92EB}\"StubPath" = "%UserProfile%\Application Data\EZSpammer.exe"
  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\"winlogin" = "%UserProfile%\Application Data\EZSpammer.exe"
  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\Explorer\run\"winlogin" = "%UserProfile%\Application Data\EZSpammer.exe"

The worm then creates the following registry entries to bypass the Windows firewall:
  • HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy\StandardProfile\"DoNotAllowExceptions" = "0"
  • HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy\StandardProfile\AuthorizedApplications\List\"%CurrentFolder%\[ORIGINAL FILE NAME].exe" = "%CurrentFolder%\[ORIGINAL FILE NAME].exe:*:Enabled:Windows Messanger"
  • HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy\StandardProfile\AuthorizedApplications\List\"%UserProfile%\Application Data\EZSpammer.exe" = "%UserProfile%\Application Data\EZSpammer.exe:*:Enabled:Windows Messanger"

It then creates the following registry entry:
HKEY_CURRENT_USER\Software\VB and VBA Program Settings\SrvID\ID\"|Ae*}jFVWT" = "Blackshades"

It then attempts to open a back door on the compromised computer by connecting to the following locations:
  • ighetto.no-ip.org
  • ipinfodb.com

The worm then awaits for commands that allow an attacker to perform the following actions on the compromised computer:
  • Hijack the audio or video on the compromised computer
  • Inject itself into other running executable files
  • Perform distributed denial of service (DDOS) attacks through UDP flooding
  • Record all keystrokes
  • Run as a proxy, redirecting an attackers traffic
  • Sniff network traffic
  • Upload or download files through HTTP and FTP

Next, the worm may steal passwords from the following applications:
  • Mozilla FireFox
  • MSN Messenger
  • .NET Messenger

The remote attacker may attempt to spread the worm through the following file-sharing applications, if installed on the compromised computer:
  • Vuze
  • LimeWire
  • uTorrent
  • BitTorrent

The worm may steal the license number, register name, and CD key of the following applications:
  • ACDSystems PicAView
  • Act of War
  • Adobe Photoshop 7

  • Advanced PDF Password Recovery Pro
  • Advanced ZIP Password Recovery

It then attempts to spread by copying itself as the following file on all removable drives:
%DriveLetter%\[ORIGINAL FILE NAME].exe

The worm then creates the following file so that it runs when the above drives are accessed:
%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.

2. Restoring settings in the registry
Many risks make modifications to the registry, which could impact the functionality or performance of the compromised computer. While many of these modifications can be restored through various Windows components, it may be necessary to edit the registry. See in the Technical Details of this writeup for information about which registry keys were created or modified. Delete registry subkeys and entries created by the risk and return all modified registry entries to their previous values.
