If you're a grad student interested in security/program analysis and looking for something fun, I would love to see someone revisit the APEG problem (posed by Brumley in http://bitblaze.cs.berkeley.edu/papers/apeg.pdf ). There's *at least* one entire PhD worth of problems in that area.

At the time, there were few legitimate career paths for hackers. We thought it would be amazing to do what we loved and actually get paid for it. It worked for a while, but the hard lessons of business and friendship still haunt me to this day... https://twitter.com/todayininfosec/status/1081994322856136704 …pic.twitter.com/S0xK8FJm16

New blogpost: Sanitized Emulation with QEMU-AddressSanitizer https://andreafioraldi.github.io/articles/2019/12/20/sanitized-emulation-with-qasan.html … I just open-sourced my QEMU patches to fuzz binaries with ASan, QASan. You can also use it with ARM targets on Linux, a thing that you can't do with LLVM ASan!

Pro-tip. Ever wonder what a structure _actually_ looks like in memory when it's full of unions, typedefs, etc? The `pahole` command (from the `dwarves` package) can take in an ELF with DWARF symbols and output the structures unrolled recursively. Example:https://gist.github.com/gamozolabs/0ec182194706b6e0a3a1ee1a5ae09e17 …

Attendees coded something just like this from scratch at
@BlackHatEvents arsenal, and will do it again at@hackaday superconference. 50¢ attiny25, tiny PCB, and Z-tape instead of solder to hold it in place. Cheap and easy doesn't begin to describe it.https://twitter.com/a_greenberg/status/1182325724973191170 …
