According to Malware Specialist Symantec, there now exists a trojan (a malicious program) that specifically targets Playstation Portables (PSPs). The trojan takes advantage of recent entrances to the PSP which allow users to run non-signed code (programs and apps not sanctioned by Sony). The trojan, dubbed Trojan.PSPBrick, masquaerades as a download which offers to enable additional capabilities to users. But instead of letting PSP owners execute 'homebrew" codes, the trojan deletes four vital system files required for the PSP to boot its OS, causing the device to become, literally, a useless brick.
Judging from how the trojan does not contain the means to spread to other users from affected PSP units, Symantec reports that the malware isn't causing big damage as of yet- PSP owners who refrain from using unsigned code will be safe.
WHICH leads the conspiracy theorist in me to believe that this 'trojan' may be something that could have been engineered intentionally FOR Sony's interest in punishing users who want to bend the rules a bit to get more out of their PSPs. Hmm? If players get scared of free downloads, they'll stay and use Sony's regulated software. Far-fetched? Maybe. Maybe not. Hmmm.
Now, if Sony got their act together on their portable and provided support for encoding video, internet browsing and other cool stuff, then maybe hacking or getting homebrew software won't be necessary. And maybe (but not likely given how crappy the game lineup is) I'd consider getting myself one of these bricks-er, I mean, PSPs.
