Linux/Unix Backdoor Trojan



Symantec has released the details on a new Linux/Unix Trojan horse, which introduces Backdoor.Maxload into the system. The Trojan Horse, which is appearing on various download sites, is falsely described as an application that exploits the Windows DCOM exploit to entice users to download and run.

New Windows Virus shows up on the radar



A new virus, introducing some very ugly results, has started showing up in a few locations. Anti-Virus vendor results show what appears to be a new Backdoor based on the Windows DCOM exploit. More information will be posted as it becomes available.
