Half a billion users worldwide use WinRAR for creating and extracting archives.
This usually is assumed to be a safe procedure, however, we found a critical vulnerability that results in RCE by simply using WinRAR to extract an archive.
After we published some of the details regarding the vulnerability it quickly spread through the cyber-crime world.
In this talk we tell the story of how exactly we found the vulnerability and how we exploit it.
This is no ordinary story as you can imagine that finding a 19 year old bug in such a high profile software isn't.
We will share the fuzzing process using WinAFL, the way of thinking, and the evolution of our fuzzer/harness until we found the critical bug.
We will fully disclose the root cause the exploitation process and the mitigations we had to overcome, as well as speaking about the aftermath of such mainstream event.
