After my last livestream - youtube.com/watch?v=Nwwvtc_jsio - I've spent some time analyzing the weird behaviors I've encountered during the stream. It turns out that my 'genetic programmer' actually found minor QEMU/Unicorn engine bugs.
Bugs:
github.com/unicorn-engine/unicorn/issues/957
github.com/unicorn-engine/unicorn/pull/844/commits/ad767abda815f5c79b6658bf75ffc393a6a3c45c#diff-a84d869a16d93ba3091d2c95fbdadd27
Bonus links (pretty random):
Note: There are A LOT of ways to detect a VM. These bugs are low severity, but fun to find (+usually they are pretty educational) :)
