"Technical challenges"? More like horrors! Let's explore first the technical debt of old file formats, with the evolution of the "MP3" format. Then we go through more recent forms of file format abuses and tools: polyglots, polymocks, and crypto-polyglots. Last, an overview of recent collisions and other forms of art with MD5. They say that with file formats, "specs are enough". Should we laugh, cry or run away screaming? Presented at Digital Preservation Coalition's CyberSec & DigiPres event.]]>

A few people since called him 'successful', but LOL, if only they knew.... And now, the author will do another (big!) mistake: instead of hiding in shame as he probably should, he'll share his mistakes with anyone bored enough to attend, in the hope that he's the last person to ever look that dumb to commit such mistakes. If you're a genius and you know what to do in life, please skip this. Seriously.

Presented at Troopers 2016. When Infosec and Digipres share interests... TL;DR - Attack surface with file formats is too big. - Specs are useless (just a nice ‘guide’), not representing reality. - We can’t deprecate formats because we can’t preserve and we can’t define how they really work - We need open good libraries to simplify landscape, and create a corpus to express the reality of file format, which gives us real “documentation”. - Then we can preserve and deprecate older format, which reduces attack surface. - From then on, we can focus on making the present more secure. - We don't need new formats: reality will diverge from the specs anyway - we need 'alive' (up to date, traceable) specs.]]>
