Windows AND Linux virus

by Ivana Strahija on April 8th, 2006 A proof-of-concept has been published by Kaspersky Labs to warn about a new cross-platform virus.

The virus that can infect both Windows and Linux systems is rather simple and does not appear to have caused much harm yet, says Kaspersky. But, according to various security experts, this virus is troubling because of its cross-platform nature, which might be a sign that virus writers are developing new tactics.

Kaspersky named the virus Virus.Linux.Bi.a/Virus.Win32.Bi.a. Its written in assembler and can infect various file formats of Linux and Windows. Shane Coursen, senior technical consultant at Kaspersky, thinks that cross-platform viruses were just a matter of time, because a growing number of people are starting to use Linux for desktop comouters.

Johannes Ullrich of SANS Internet Storm Center suggests that whoever wrote the virus must have had a difficult job. -Writing a cross-platform worm is difficult because it limits you to functions that are available on both operating systems. You have to also code the virus in assembly to make it work without relying on any OS-specific function.'

Although this is not the first time such virus surfaced (sadmind/ISS worm or Winux for instance), it's a good reminder to all of us to take our computer security seriously.
