W32/Sdbot-UH is a worm which attempts to spread to remote network shares with weak passwords. The worm also contains backdoor Trojan functionality allowing unauthorised remote access to the infected computer via IRC channels while running in the background as a service process.

W32/Sdbot-UH creates the files uqice.exe (detected as W32/Sdbot-UH) and fabolous.exe (detected as Troj/Ranck-CE) in the folder C:\WINNT\SYSTEM32.

W32/Sdbot-UH copies itself to the Windows system folder as dytevevi.exe and creates the following registry entries to ensure it is run at system logon:

dytevevi.exe

HKLM\Software\Microsoft\Windows\CurrentVersion\Run
boqamah
dytevevi.exe

HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices
