-----BEGIN PGP SIGNED MESSAGE----- Internet Security Systems Security Brief December 26, 2002
Dynamic Trojan Horse Network Hybrid Threat Propagation Synopsis: ISS X-Force has been monitoring the spread of the Dynamic Trojan Horse Network (DTHN) Internet worm. DTHN propagates through email and through open NetBIOS file shares. DTHN installs itself and establishes communication to a sophisticated peer-to-peer communications network, to further spread infections and launch additional attacks. Impact: As with most network worms, DTHN propagation can cause network congestion, automatically compromise victim systems, and configure a sophisticated network that can be used for Distributed Denial of Service (DDOS). Once the backdoor is installed, it can be accessed by the author, or third party attackers.
