W32/Rbot-AXC is a network worm with backdoor Trojan functionality for the Windows platform.
The worm copies itself to a file named winssh.exe in the Windows system folder and creates the following registry entries:
HKCU\Software\Microsoft\OLE
Windows SSH Client
"winssh.exe"
HKCU\Software\Microsoft\Windows\CurrentVersion\Run
Windows SSH Client
"winssh.exe"
HKCU\Software\Microsoft\Windows\CurrentVersion\RunServices
Windows SSH Client
"winssh.exe"
HKCU\System\CurrentControlSet\Control\Lsa
Windows SSH Client
"winssh.exe"
HKLM\SOFTWARE\Microsoft\OLE
Windows SSH Client
"winssh.exe"
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Windows SSH Client
"winssh.exe"
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
Windows SSH Client
"winssh.exe"
HKLM\SYSTEM\CurrentControlSet\Control\Lsa
Windows SSH Client
"winssh.exe"
W32/Rbot-AXC spreads using a variety of techniques including:
-exploiting weak passwords on computers and SQL servers
-exploiting operating system vulnerabilities RPC-DCOM (MS04-012), WKS (MS03-049) (CAN-2003-0812), MSSQL (MS02-039) (CAN-2002-0649), PNP (MS05-039) and ASN.1 (MS04-007)
-using backdoors opened by other worms or Trojans.
W32/Rbot-AXC can be controlled by a remote attacker over IRC channels. The backdoor component of W32/Rbot-AXC 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)
