A new PSP bricker is on the loose, and has already been wreaking havoc to PSP users unfamiliar with it's looks. The bricker is enclosed in folders labeled "SDL-TEST-5" and "SDL-TEST-5%", is about 70 KB, and will, most definitely, render your PSP useless, should the EBOOT be executed. Try using the new version of PSafeP by Dark Killer to scan your recently downloaded homebrew applications for potential traces of this PSP killer.
