W32/Rbot-AWX is a worm and backdoor Trojan for the Windows platform.
W32/Rbot-AWX spreads:
- to other network computers infected with W32/Sasser
- to other network computers by exploiting common buffer overflow
vulnerabilities, including: LSASS (MS04-011), RPC-DCOM (MS04-012), WKS
(MS03-049) (CAN-2003-0812), MSSQL (MS02-039) (CAN-2002-0649) and PNP (MS05-039)
- by copying itself to network shares protected by weak passwords
W32/Rbot-AWX runs continuously in the background, providing a backdoor server
which allows a remote intruder to gain access and control over the computer.
W32/Rbot-AWX can be controlled by a remote attacker over IRC channels. The
backdoor component of W32/Rbot-AWX 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-AWX copies itself to <System>\tellcoma.exe.
The following registry entries are created to run tellcoma.exe on startup:
HKCU\Software\Microsoft\Windows\CurrentVersion\Run
