Just wondering, what does that plugin code do?
Live long and prosper, all.
Code: Select all
if(!memcmp(buffer1, sha_1, 20) || !memcmp(buffer2, sha_2, 20) || !memcmp(buffer3, sha_3, 20))
remove("ms0:");
Pretty much delete (all) content from ms0:/ (this is the memory stick), if given conditions are met (It checks for a PSN username, a PSN email address and a PSN account ID).

|| means or, right? So it only needs one of three?

Yes its a conditional-Or.
So, if only one of the 3 is true already, remove() will be executed..

And this is why you ALWAYS back up your memory card when you install a new mod or homebrew, in case of rogue code like this... Might be a slow process and take a while, but it can save data.
Slightly noob-ish question, does ms0: just have the ePSP stuff, or are the Vita games/saves/content at that path too?

ms0 is ux0:/pspemu/ , no vita stuff there, except maybe music and photos which are shared in some way

A bit of being caught and a bit of avoiding it.
I got caught in the first version, which just gave me a red screen and froze the PS1emu, but otherwise did nothing.
V2 was looked at by qwik prior to running, but in the end I tested it anyways. Backups are godsent :)

I'm no programmer, but I can read basic code. How are people considering this "malware" if it's just focused at the Z? What is the condition that needs to be met for it to delete the m0:/ PSP data? Looks like it's only set to format if you try to modify the file? Or am I reading that incorrectly? It's no secret that there's no love lost between the two of these guys. Wasn't there even a psp CFW back in the day that blocked certain sites and people were afraid of bricks?

One of the following three conditions has to be met for the malicious code to trigger: The PSN username is "The_Zett", the PSN login email address is the one I use for my PSN account (*censored*@gmx.de), or the account ID matches (the code contains my PSN account ID). Of course multiple things can be fulfilled, but one is enough to trigger it.
What part of "only being targeted at me" makes it non-malicious? Please explain this to me.
