I've been around here for about 13 years and have never once heard of anyone loosing $1000+ from the Auran/N3V store. You'd expect that in 13 years of being around if someone had, I would have heard it.
Your going to much more likely to be hacked getting torrents then buying thru a legitimate store. Heck I could probably get your IP in a matter of mins, and I'm no hacker...
