Season’s Greetings
To all our customers, staff (past and present), business partners, friends and associates I’d like to wish a joyous and peaceful festive season.

As the year winds down, it’s time to mention a few internal victories that are fun to share: Daniel Cuthbert and Rogan Dawes (both staunch OWASP proponents) have joined our assessment team, which is a big boost. Welcome guys! Glenn Wilkinson, a lead analyst, had his Masters thesis listed on Amazon Dominic White was interviewed in all his glory on .za teevee over Wikileaks
Playing with Python Pickle #3

Playing with Python Pickle #2
[This is the second in a series of posts on Pickle. Link to part one.] In the previous post I introduced Python’s Pickle mechanism for serializing and deserializing data and provided a bit of background regarding where we came across serialized data, how the virtual machine works and noted that Python intentionally does not perform security checks when unpickling. In this post, we’ll work through a number of examples that…

Serialized objects can be useful to an attacker from a number of standpoints: such objects could expose data where naive developers…

Analysis of a UDP worm
From time to time I like to delve into malware analysis as a pastime and post interesting examples, and recently we received a malware sample that had a low-detection rate. Anti-Virus coverage was 15/43 (35.7%) based on a virustotal.com report and Norman sandbox did not detect any suspicious activity as shown in the report below: Norman sandbox report did not show any registry or network activity. This might be due to the…
