Intego’s VirusBarrier antivirus software is now offering protection against the newly discovered Oompa-Loompa Trojan horse, also called OSX/Oomp-A or Leap.A. This security threat affects Macintosh computers running Mac OS X on PowerPC processors. Replicating by sending itself to users’ iChat buddies, the Oompa-Loompa Trojan horse does not delete any files, but infects applications on computers where it runs, enabling those applications to in turn spread the virus. “Two versions of this Trojan horse exist, and the Intego Virus Monitoring Center immediately developed updated virus definitions, which it released on February 14, 2006, as soon as it discovered this threat, ensuring that VirusBarrier X and VirusBarrier X4 eradicate the Oompa-Loompa Trojan horse. All Intego VirusBarrier X and VirusBarrier X4 users should make sure that their virus definitions are up to date by using the NetUpdate preference pane in the Mac OS X System Preferences.” UPDATE: Intego has also posted a Q&A on the new Oompa-Loompa Trojan horse.
