Welcome to the Tech Inc Capture the Flag (CTF) training event series!

The format of this series is likely to evolve over time, but I currently assume that these evenings will feature a combination of web-based challenges, online competitions, and general-purpose learning/workshop evenings covering a variety of computer security (i.e. hacking, defensive) topics. Everyone of all skill levels is welcome!!!!

About the CTF Training Evenings

Types of evenings

I envision the following 3 kinds of CTF training evenings:

• 1 - Workshop/learning evenings - network analysis/forensics (Wireshark), filesystem forensics, reversing(Ollydbg, etc..)/Pwnables, code deobfuscation, pen testing (Kali-Backtrack/Metasploit/buffer overflows), cryptanalysis, web security (XSS, SQL injection, etc..), stegonography, Commandline kung-fu, recon/trivia/etc..
  • Example: I've got a whole slew of Wireshark training videos - we can watch them together!
  • We could also occasionally screen Defcon/CCC/Other videos on fun topics!

• 2 - Challenge website evenings
  • I setup a Scoreboard, so we can keep track of who's done which challenges

• 3 - Actual CTF events
  • There's a bunch of them on CTF Time - we participate occasionally!

Other things that we can do

• Setup a vulnerable server (Damn Vulnerable Linux, Metasploitable, etc..) and attack it
  • Other examples: http://exploit-exercises.com/
• Preparing for competitions
  • Setup Etherpad (or another online "multiplayer notepad") so people can make notes and work together for each challenge
    • We're currently using: Riseup Pad
  • Preparing tools (Backtrack VM, other VM images with different tools)
  • Being able to emulate weird architectures for binaries
  • Being able to test shellcode on our own system
  • Maybe we can do something with hardware in the space (i have no idea what the status is of VMWare cluster in space, but i think we have one..)
• Brainsmoke could talk about binary exploitation
  • We can also look at gdb / objdump / IDA / Hex-Rays
