 +
== Types of evenings ==
 +
 
 +
I envision the following 3 kinds of CTF training evenings:
 +
 
 +
* 1 - '''Workshop/learning evenings''' - network analysis/forensics ([http://www.wireshark.org Wireshark]), filesystem forensics, reversing([http://www.ollydbg.de Ollydbg], etc..)/Pwnables, code deobfuscation, pen testing ([http://www.kali.org Kali]-[http://www.backtrack-linux.org Backtrack]/[http://www.metasploit.com Metasploit]/buffer overflows), cryptanalysis, web security (XSS, SQL injection, etc..), stegonography, [http://blog.commandlinekungfu.com Commandline kung-fu], recon/trivia/etc..
 +
** Example: I've got a whole slew of [https://www.lcuportal2.com/check-out-these-courses.html Wireshark training videos] - we can watch them together!
 +
** We could also occasionally screen [https://www.youtube.com/user/DEFCONConference Defcon]/[http://media.ccc.de/browse/congress/ CCC]/[http://www.securitytube.net Other] videos on fun topics!
 +
 
 +
* 2 - '''Challenge website evenings'''
 +
** I setup a [[TechInc-CTF-Scoreboard|Scoreboard]], so we can keep track of who's done which challenges
 +
 
 +
* 3 - '''Actual CTF events'''
 +
** There's a bunch of them on [http://ctftime.org/ CTF Time] - we participate occasionally!
 +
 
 +
== Other things that we can do ==
 +
 
 +
* Setup a vulnerable server ([http://www.securitydistro.com/security-distros/damn-vulnerable-linux-dvl Damn Vulnerable Linux], [http://www.offensive-security.com/metasploit-unleashed/Metasploitable Metasploitable], etc..) and attack it
 +
** Other examples: http://exploit-exercises.com/
 +
* Preparing for competitions
 +
** Setup [http://etherpad.org Etherpad] (or another online "multiplayer notepad") so people can make notes and work together for each challenge
 +
*** We're currently using: [https://pad.riseup.net Riseup Pad]
 +
** Preparing tools ([http://www.backtrack-linux.org 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

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!!!!

Our current schedule is a meeting at techinc every first monday of the month, we also try to do a ctf event every 1/2 months.

Training Evenings

Upcoming

  • July 14 - Dimitris (Volatility)
  • August 4 - Brainsmoke (Binary exploitation walkthrough)
  • August 11 - Melanie (wargame or video - TBD)
  • August 25 - Hitcon Retrospective
  • By default, Melanie will fill in the weeks that aren't taken by anybody else

About the CTF Training Evenings

Types of evenings

I envision the following 3 kinds of CTF training evenings:

  • 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
  • Preparing for competitions
    • Setup Etherpad (or another online "multiplayer notepad") so people can make notes and work together for each challenge
    • 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
