A virus that affects both Linux and Windows platforms could be unleashed into the wild.
The security software company Kaspersky Labs and the SANS Internet Storm Center have reported the appearance of the proof of concept virus.
They have warned that remote attackers could now be planning to attack both operating systems at the same time.
There have only been a small number of attempts to distribute a single virus that targets both platforms at the same time.
Virus writers have instead concentrated on producing specific threats for each system, usually because it is easier to write rogue code for a single operating system. But this could now change, warned both Kaspersky and SANS.
The cross-platform virus has been given the “Virus.Linux.Bi.a/Virus.Win32.Bi.a” tag by Kaspersky. The virus only infects those files in the current directory of systems, so is seen as only a low-level threat.
As more companies adopt Linux, the appearance of more cross-platform viruses are expected to appear in the wild, said SANS.
