Haven't been CTFing much lately; played CSAW and solved a couple of things. Had planned to do writeups but didn't get to it and now they're out of cache. Was excited about hack.lu but it was during business travel. I guess I could be playing HITCON right now but I got home late last night from travel and have been reassembling my life. My hard drive died and I had to replace it with an SSD while I was on the road, and I haven't pulled my CTF tooling off of my backup yet. On the upside, SSDs are fast! I had no idea what I was missing out on.
Haven't been reading much lately either for that matter, but such as I have been:
Moving AFL's coverage instrumentation into the generated TCG code in order to re-enable the translation-block linking optimization. Good stuff.
Some of the documentation for kAFL. I know jack about kernel bugfinding or exploitation; I should fix that. I guess I did read part of this Project Zero writeup of a kernel bug lately, but at some point they lost me.
Bunch of libfuzzer and llvm docs.
Read a bit of this gitbook on heap exploitation a while back; I should finish it. Did get the exploit I was working on to work though, so that was cool.
This really good stackoverflow answer on all the C runtime stuff that gets linked in automatically by the link driver, but that you need to include yourself if you're doing weird manual linking tricks.
Python IntervalTree documentation; I'd used these a couple of years ago but it was good to refresh on.
Python mmap documentation; I hadn't seen this before but came across some code that was using it. Nice trick, looks performant.
A coworker recommended this book on debugging to me recently; haven't decided whether I'm going to read it yet or not. On the one hand, it looks promising, but on the other, if it's actually nine rules and a bunch of examples, maybe I could do without all the examples. Might see if I can get my employer to buy a copy for the office.
Re-read the Hovamol on the plane, and part of the Bhagavad Gita (good enough for Oppenheimer, good enough for me).
