Linus Torvalds repairs Linux kernel for "multiplatform virus"

Recently, a report from the anti-virus software manufacturer Kaspersky caused quite a stir: The first proof-of-concept virus was discovered which, although it has no real damage routine, can spread on both Windows and Linux.

Broken

The online news service Newsforge took a closer look at Virus.Linux.Bi.a / Virus.Win32.Bi.a and discovered a number of interesting details: For example, it turned out that the "virus" does not appear on Linux all systems worked.

Patch

Finally, Linus Torvalds took on the problem very personally and came to the conclusion that the "virus" could not develop its functionality due to a bug in the gcc in conjunction with current kernel versions. To eliminate this "problem", Torvalds has meanwhile developed a patch so that Virus.Linux.Bi.a should also run under future kernel variants.

Motifs

However, this discovery also raises questions about the seriousness and motives of the Kaspersky report. After all, the "error" only occurs with a combination of assembler code with outdated system calls. This suggests that the "virus" is by no means a new malware threat, but rather old code, and that Kaspersky may only want to stimulate a new business with the report, according to Newsforge doubtfully.

Do what it should

In this context, Linus Torvalds raises a much more fundamental question, namely what actually makes the code a virus. After all, this is simply a program that, when executed, does things (files that it has permission to modify) that are in no way wrong. In this respect, the cross-platform component of Virus.Linux.Bi.a is particularly interesting, but not just any viral component. (red)
