This was a fun forensics challenge.
You're given a ~300mb zip file which when unzipped contains two files.
1) Windows 7 .vmem file
2) bsides.KDBX
Google 'KDBX', its a Keepass 2.x safe file.
So presumably the challenge is to find the password to the safe file somewhere in memory.
Grep through the .vmem looking for 'password'.
$ grep -a password *.vmem > things
Lucky us, theres a string hidden in here:
Using keepass 2.x you can import the password safe and unmask the password to reveal the answer.
Many thanks to @bsjtf for the fun challenges :)
