Whether it's profile pictures, PDF invoices, or archive files, handling raw uploads means you're trusting external input to behave. . The file sitting on your disk isn't actually the threat.

"It is more laid back this year," acknowledged Jeff Moss, the founder of the conference, now in its ninth year. "It is more a reflection of what is going on in the hacking community." While the hacking counterculture was still in attendance, its members seemed in the minority at the gathering of 4,500-plus people.
