More Information
W32/Rbot-AWP is a network and IM worm and an IRC backdoor Trojan for the Windows platform.
W32/Rbot-AWP 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-AWP spreads to other network computers:
- by exploiting common buffer overflow vulnerabilities, including: LSASS (MS04-011), RPC-DCOM (MS04-012), WKS (MS03-049) (CAN-2003-0812) and PNP (MS05-039)
- by copying itself to network shares protected by weak passwords
- by sending itself via MSN Messenger, Yahoo Instant Messenger and AOL Instant Messenger
When first run W32/Rbot-AWP copies itself to <System>\task-mngr.exe.
The following registry entries are created to run task-mngr.exe on startup:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Windows Bootup
task-mngr.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
Windows Bootup
task-mngr.exe
Registry entries are set as follows:
HKLM\SYSTEM\CurrentControlSet\Control\Lsa

HKLM\SOFTWARE\Microsoft\Ole
