Malicious programs for computers have been around for more than 20 years. It was the birth of the Internet which really enabled these digital pests to make a breakthrough.
Until now, gaming consoles have been more or less immune to malware. Yes, there're been Trojans for the Nintendo DS console (Trojan.Nintendo.Taihen.a and .b) and for the Sony Portable Playstation (Trojan.PSP.Brick.a) but the number of victims has been small. This is because the user has to tweak the console in order for so-called homebrew software (i.e. software not certified by the console manufacturer) to run.
There's a Linux distribution available for the Sony Playstation 2 (which will also be available for Playstation 3) which just cries out for programming. However, any programs created will only run on Playstations which have the distribution installed.
Microsoft recently announced that in future, users will be able to purchase a development kit with a $99 a year registration fee - no Linux here. Programs developed using the kit will only run on Xboxes where the user has also paid the registration fee, and they can only be copied to another console as source code. From a security point of view, this is a wise decision.
I hope that things won't change much in the near future. If Sony, Microsoft , Nintendo or hackers made it possible to easily download programs developed by users via the Internet, Pandora's box would be opened. The combination of unprotected gaming consoles, the Internet and the possibility of previously unknown vulnerabilities would lead to gamers who had been immune to malware becoming a target for virus writers.
Trojans for gaming platforms are taking off - Sony PlayStation Portables last week, Nintendo DS - today. That takes care of two major handheld entertainment systems. MS Xbox next week?
So far the only result is broken consoles. And only for people who chose to download suspicious files or pirated games. However, any time virus writers break open a new platform, the community should take notice.
Anyway, now that our computer games have been violated, are fridges next?
By the way, we detect the Sony Trojan Trojan.PSP.Brick.a, and the Nintendo Trojan as Trojan.Nintendo.Taihen.a.
