    Is there an equiv to /proc/cpuinfo for Windows besides coreinfo? Coreinfo doesn't have what I'm interested in sadly.

    Sometimes all you need is a bit of a nice looking status screen to brighten your fuzzing time.. ?

    Merry freaking Christmas! Finally have my first real project fuzzing in barbervisor. This was a fuzz run that used to take 15 to 20 sec per fuzz case and now is doing 11 cases per sec. It already repro'ed the same bug organically that took the old fuzzer a week to find.

    Ups and downs.. but am finally able to repro a fuzz case that was 1 exec/15 sec to 5 exec/sec/core in my hypervisor (name pending). Snapshot fuzzing is so much fun to work in.

    Just getting into the optimization game. Are there any other recommended reads besides the Agner Fog manuals?

    We recently improved our ctags fuzzer to use some keywords from a dictionary and now we're fuzzing all parsers and some command line flags too. We found another NULL deref, an OOB global read, and of course... and OOB controlled global write :D

    First huge breakthrough this week. Finally reproduced a snapshot of 14B instructions in my bare metal hypervisor. Now, off to multicore the process. Luckily, things /should/ already be in place. *Cross fingers*

    Mobile pentesters.. how often are you looking at native code for bugs vs bugs in the app itself? Having no mobile experience, am curious of what the typical attack surface is like.

    "if it's not open source you cannot audit it"

    [thread] Reading a lot of C++ code lately, there are quite a few features I miss from tools for binary reverse engineering.
