More Information
W32/Sdbot-RE is a worm that attempts to spread via remote network shares. The worm tries to access various network computers with shared folders using weak passwords.
W32/Sdbot-RE contains backdoor Trojan functions that allows unauthorised remote access to the infected computer via IRC channels while running in the background.
When run W32/Sdbot-RE copies itself to the Windows system folder as dsabdw.exe.
The worm also creates the following registry entries so that it is able to run on user logon or computer restart:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
DASDS VSAVdjs = dsabdw.exe
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices\
DASDS VSAVdjs = dsabdw.exe
HKCU\Software\Microsoft\Windows\CurrentVersion\Run\
DASDS VSAVdjs = dsabdw.exe
W32/Sdbot-RE will attempt to perform the following actions when instructed to do so by a remote attacker:
- download and run files from the Internet
- partake in DDoS (denial of service) attacks
- may copy to network shares as the filename abbsasn.exe
- steal computer information (eg. CPU, memory)
- terminates processes
Sophos's anti-virus products include proactive protection technology, which can defend against new threats without requiring an update. Sophos customers have been protected against W32/Sdbot-RE (detected as W32/Sdbot-Fam) since version 3.85.
