Plexus worm targets Microsoft vulnerabilities
Monday, 7 June 2004 10:02 ESTAntivirus software companies have warned of an e-mail worm that targets unpatched Microsoft Windows machines with either of two recently disclosed software vulnerabilities. The worm, known as both "Plexus" and "Explet.A", was first detected last week and spreads by exploiting Windows machines with vulnerabilities used by two recent worms, Sasser and Blaster. Network Associates' McAfee Antivirus Emergency Response Team and Symantec both said the new worm does not pose a serious threat, but have issued software updates to detect it.
Plexus exploits the Windows component called Local Security Authority Subsystem Service, or LSASS, which Microsoft patched in April. Plexus can also crawl through a hole in a Windows component called the DCOM (Distributed Component Object Model) interface, which handles messages sent using the RPC (remote procedure call) protocol.
