More Information
W32/Rbot-AXL is a worm and IRC backdoor Trojan for the Windows platform.
W32/Rbot-AXL spreads to other network computers infected with W32/MyDoom and to other network computers by exploiting common buffer overflow vulnerabilities, including LSASS (MS04-011), RPC-DCOM (MS04-012), WKS (MS03-049) (CAN-2003-0812), WebDav (MS03-007), UPNP (MS01-059), Veritas (CAN-2004-1172), Dameware (CAN-2003-1030) and ASN.1 (MS04-007).
W32/Rbot-AXL runs continuously in the background, providing a backdoor server which allows a remote intruder to gain access and control over the computer via IRC channels.
W32/Rbot-AXL can be controlled by a remote attacker over IRC channels. The backdoor component of W32/Rbot-AXL can be instructed by a remote user to perform the following functions:
capture screen/webcam images
download/execute arbitrary files
packet sniffing
port scanning
start a remote shell (RLOGIN)
start an FTP server
take part in distributed denial of service (DDoS) attacks
When first run W32/Rbot-AXL copies itself to <System>\sysin.pif.
The following registry entries are created to run sysin.pif on startup:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Win CPU
sysin.pif
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
Win CPU
sysin.pif
Registry entries are set as follows:
HKCU\Software\Microsoft\OLE
Win CPU
sysin.pif
HKLM\SOFTWARE\Microsoft\Ole
EnableDCOM
N
HKLM\SYSTEM\CurrentControlSet\Control\Lsa
