Amazing Discovery.
It is a well documented exploit that will enable users to run homebrew applications on their PSP as from v2.80 of the system software. Sony seems to already have plugged this hole with their release of 2.81 which by all reports seem only an update to eliminate this exploit.
So well done to Panda. Are they now going to supply antivirus software for the PSP. In that case they will need the 2.80 exploit, because Sony seems to be defending their turf vigorously.
Or should we say thank you to Sony for eliminating the risk associated with homebrew, to force people to use things like mod chips.?
