W32/Sdbot-AGZ is a network worm with backdoor functionality for the Windows platform.
When first run, W32/Sdbot-AGZ copies itself to the Windows system folder as flxper.exe and creates the following registry entries in order to run each time a user logs on:
HKCU\Software\Microsoft\Windows\CurrentVersion\Run
NotFaut
"flxper.exe"
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
NotFaut
"flxper.exe"
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
NotFaut
"flxper.exe"
The worm spreads through network shares protected by weak passwords, MS-SQL servers and through various operating system vulnerabilities.
W32/Sdbot-AGZ connects to a predetermined IRC channel and awaits further commands from remote users. The backdoor component of W32/Sdbot-AGZ can be instructed to perform the following functions:
scan networks for vulnerabilities
download/execute arbitrary files
start an ftp server
