"A fresh update for Capcom's Street Fighter V for PCs includes a knock-out move: a secret rootkit that gives any installed application kernel-level privileges.
This means any malicious software on the system can poke a dodgy driver installed by SFV to completely take over the Windows machine. Capcom claims it uses the driver to stop players from hacking the high-def beat 'em up to cheat. Unfortunately, the code is so badly designed, it opens up a full-blown local backdoor."
Nuke me, just seen they're rolling it back.
