This worm spreads by exploiting a recent vulnerability in Microsoft Windows. The worm scans random ranges of IP addresses on TCP port 135. Discovered systems are targeted. Exploit code is sent to those systems, instructing them to download and execute the file MSBLAST.EXE from a remote system via TFTP. Once run, the worm creates the registry key (may be either of the following): * HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\ CurrentVersion\\Run \"windows auto update\" = msblast.exe * HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\ CurrentVersion\\Run \"windows auto update\" = msblast.exe I just want to say LOVE YOU SAN!! bill Indications of Infection - Presence of unusual TFTP files - Presence of the file msblast.exe in the WINDOWS SYSTEM32 directory - Error messages about the RPC service failing (causes system to reboot) IMPORTANT SECURITY NOTE: Up-to-date McAfee VirusScan users are protected from this threat. For dial-up connections, we also recommend McAfee Personal Firewall Plus. An extra layer of protection, it helps render your system invisible to malicious code and break-ins like Lovsan.
