W32/Rbot-FKT is a worm and backdoor for the Windows platform.
W32/Rbot-FKT 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), PNP (MS05-039) and ASN.1 (MS04-007)
- by copying itself to network shares protected by weak passwords
W32/Rbot-FKT runs continuously in the background, providing a backdoor server which allows a remote intruder to gain access and control over the computer.
