-----BEGIN PGP SIGNED MESSAGE----- Internet Security Systems Security Brief October 3, 2002
Bugbear Hybrid Threat Propagation Synopsis: ISS X-Force has been monitoring the spread of the "Bugbear" Internet worm. Bugbear propagates through email and through open NetBIOS file shares. Bugbear attempts to disable all security and antivirus software on each host and installs a backdoor program. X-Force has detected a large increase in NetBIOS scanning traffic from several thousand unique addresses. Impact: As with most mass-emailing worms, Bugbear's propagation can cause resource starvation problems on email servers, and network congestion on heavily loaded network segments. Information about the nature of the backdoor program that Bugbear installs has been made public. Therefore, this backdoor can be accessed not only by the author, but also by any third-party attacker.
