unrubby: reversing without reversing

The talk “unrubby: reversing without reversing” was part of the Troopers conference in Heidelberg, 16 March 2016. The talk was done by Richo Healey, who is currently working on the security engineering team at the Irish payment company Stripe. Richo Healey is an experienced conference speaker. Amongst other he has spoken at Kiwicon, DEF CON and 44con.
 
In his talk Richo Healey spoke about reverse engineering of Ruby software. First he talked about existing tools and techniques to regenerate source code from Ruby bytecode. Then he presented a new concept, which is implemented in his tool “unrubby”.

As presented at Troopers this year, ERP-SEC research has uncovered a set of potential default accounts related to the use of SAP Solution Manager. These default accounts might pose a big risk to your SAP supported business as some of them have wide authorisations. It is therefore important to check if they exist in your landscape and change the default passwords.

How to crack a white-box without much effort

By: Philippe Teuwen (@doegox)

White-box cryptography is a relatively new field that aims at enabling safely cryptographic operations in hostile situations.
A typical example is its use in digital-right management (DRM) schemes, but nowadays you also find white-box implementations in mobile applications such as Host Card Emulation (HCE) and the protection of credentials to the cloud.
In all these use-cases the software implementation uses the secret key of a third-party which should remain secret from the owner of the device which is running this executable.

Python For Hackers

Python has reached a defacto standard in exploit development lifecycles and most of the proof of concept tools you’ll find out there are written in Python (besides the metasploit framework, which is written in Ruby). Python allows to write scripts handling with remote services, fiddling with binary data and interacting with C libraries (or Java in case of Jython/.Net in IronPython) in a fast and easy way. The huge standard library with it’s “battery included” principle removes some of the dependency hell known from other frameworks/languages. I want to share some of my python coding experiences with you, and maybe this could give some helpful tips for your future work, to make the world a bit safer 🙂 (PS: most of the examples are written in Python 3.x or compatible to both Python branches).
