Again this year was ShmooCon's Ghost in the Shellcode warm-up round or Teaser (@ShellGhostCode). Congrats to Eindbazen for winning!
There was three challenges: crypto (Tel Aviv), crackme (AL's revenge) and exploitation (Hackquest). You will notice strong references to Hackers (1995) movie. Write-ups can be found on FixMe wiki, Leet More blog or Eindbazen blog.
