Meeting - April 17, 2013 - Incident Response, Forensics, and John Sawyer!

Good morning SITers!

John Sawyer, a SIT founder & pen tester for InGuardians, will be

speaking on Wed night. We will also be holding officer elections as

well as talking about some upcoming events that SIT will be hosting.

John will be covering the following topics to get everyone prepped for

the upcoming SIT CTF on Saturday, April 20:

Incident Response and Forensics

We will do a quick introduction into the world of incident response

and forensics with a brief overview of what the different stages are,

important tools and techniques, and some hands-on examples. Pay

careful attention because some of these exercises may come in handy

during the SIT CTF.

The example exercises will be available in our GitHub repo so you can

grab them later if you miss the meeting.

Cyber Quest April 2013

Packet Capture-based Web Vulnerability Analysis


We probably won’t cover much about how to do this competition since

Mauricio has already talked about the topic, but I want to discuss it

briefly. It would be awesome to get as many UF participants as we can.

What Did We Do This Week At SIT? – April 10, 2013

UFSIT Meeting | April 10, 2013 | Decompilers!

– Announcements! –

Dr. Joe Wilson is teaching an Ethical Hacking course this Fall! - Email him for more information: jnw@cise.ufl.edu B-Sides Orlando is this weekend! CTF Approaching! - April 19th - April 21st (48 hours): Plain CTF hosted by the PPP - Hackerspace on Friday/Saturday/Possibly Sunday? Tyler Pitchford is coming to speak at UF on April 24th! - Attorney and creator of Azureus/Vuze - Giving TWO talks on Massive Open Online Courses (MOOCs | on April 24th) and Reverse Engineering (April 25th for SIT specifically) Next Fall, we will be using KALI LINUX! Kali is pretty much the newest version of Backtrack and can be downloaded at www.kali-linux.org Officer elections will be held next week!


Decompiler takes byte code and turns it into a readable source We can reverse any interpreted language which includes: - Python and Java Why?! - … to hack Minecraft of course. - Which, on a side note, it’s pretty easy to decompile Java code How?! - JAD (for Java) and UNPY (for Python)

– JAD –

1) Open up Backtrack 2) Backtrack -> Reverse Engineering -> JAD - Note: It will open up in Terminal 3) Use ./jad [path/of/class/file.class] - This will output a .jad file which you can use “cat” to display the text or open it in vim

Challenges! - There are challenges on GitHub! - If you already have the “sitgit” already setup, just navigate to [sitgit-folder]/meeting-files and use “git pull” to pull the new challenges! - I personally recommend copying them to your desktop for easy access when using JAD! - Remember that not all challenges are solvable……….

– UNPY (aka uncompyle) –

  • The zip file for UNPY is in the meeting-files folder in [sitgit-folder]! Installation: 1) Navigate to the unzipped uncompyle-master directory 2) Run “python2.7 setup.py build” 3) Run “python2.7 setup.py install” 1) Navigate to the uncompyle-master directory (or wherever you saved the uncompyle files) 2) Run “python2.7 uncomplyer.py [path/of/class/file.pyc]” 3) The output will be what’s in the [file.pyc]!

As always, if you have a question about anything, send an email to our listserv or come chat in the IRC!

Meeting - April 10, 2013 - Decompilers
