Codegate Retrospective

• We're happy with our performance at the Codegate CTF!
• Exploiting assembly code with a debugger is still one of our largest hurdles (with the exception of a few people)
• TODO Marielle: save a copy of the pad contents from Riseup.net before it disappears
• We need a better way of sharing stuff
• Dimitris setup some great infra, including a file uploader
  • Melanie sent a link to the CTF mailing list with the URL and the login credentials
  • Melanie wasn't able to successfully upload IDA Pro though -- file size limit issues
  • Another limitation is that we can't arrange things into folders ourselves
  • TODO Coolfile: setup a Knuffelhackers server + backup file sharing option, since 2 options are better than 1  :-)

• Discussion of problems - we discussed: Weirdshark and 120
• The write-ups for Codegate on CTFtime.org still aren't available yet!
  • We'll email a link to the write-ups when they are available, and can discuss them on the mailing list.

• We definitely need to have an IDA Pro reversing evening -- we'll plan this in
  • But first we need to share it with everybody
  • Melanie created a Windows VM with IDA. She can share it with everybody once the file sharing infrastructure is ready..

Binary Exploitation

• We're gonna look at Chapter 3 (Exploitation - start at Page 119) of this book:
  • Hacking: the Art of Exploitation
