W32/Sdbot-YW is a worm and IRC backdoor Trojan for the Windows platform.
W32/Sdbot-YW allows unauthorized remote access to the infected computer via the
IRC network. The worm joins a preconfigured IRC channel and waits for
instructions from a remote intruder. The worm can be instructed to download
updates and run arbitrary files, participate in DDoS attacks and spread to
remote network shares.
When first run the worm copies itself to <SYSTEM>\hmusvc32.exe or
<SYSTEM>\hmvsvc32.exe.
The following registry entries are created to run W32/Sdbot-YW on startup:
HKCU\Software\Microsoft\Windows\CurrentVersion\Run
HMV PowerSource
<worm filename>
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
HMV PowerSource
<worm filename>
where <worm filename> is either hmusvc32.exe or hmvsvc32.exe
