W32/Rbot-AKM is a network worm and IRC backdoor Trojan for the Windows platform.
W32/Rbot-AKM spreads using a variety of techniques including exploiting weak passwords on computers and SQL servers, exploiting operating system vulnerabilities (including LSASS and PnP) and using backdoors opened by other worms or Trojans.
W32/Rbot-AKM can be controlled by a remote attacker over IRC channels. The backdoor component of W32/Rbot-AKM can be instructed by a remote user to perform the following functions:
start an FTP server
start a Proxy server
start a web server
take part in distributed denial of service (DDoS) attacks
log keypresses
capture screen/webcam images
packet sniffing
port scanning
download/execute arbitrary files
start a remote shell (RLOGIN)
The worm copies itself to a file named pnpsrv.exe in the Windows system folder and creates the following registry entries:
HKCU\Software\Microsoft\Windows\CurrentVersion\Run
Windows PNP Server
"pnpsrv.exe"
HKCU\Software\Microsoft\Windows\CurrentVersion\RunServices
Windows PNP Server
"pnpsrv.exe"
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Windows PNP Server
"pnpsrv.exe"
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
Windows PNP Server
"pnpsrv.exe"
