Remember my script to extract data from MS-SQL TDS streams? Well here is a bit of an introduction to the Bro Network Security Monitoring software which implements my functionality using Bro‘s scripting language.

If you find monitoring networks for security related artefacts interesting, or it’s your job, then read on as I demonstrate some of Bro‘s scripting flexibility by using it to extract MS-SQL commands and login information from network traffic.

It’s been four months since the Bash ShellShock vulnerability was made public, and for some reason I hadn’t thought of modifying Dionaea to analyse and download any URLs in inbound ShellShock exploits until a week ago! If you’re interested in using Dionaea to download the URLs that in-the-wild ShellShock exploits are trying to download, or if you just like hairy regular expressions, then read on. Continue Reading

It’s been about a year and a half since I wrote about a behavioural approach to automated unpacking, and I figured it was time to add some more functionality to This time, I’m going to look at malware decrypting/decompressing code from within itself, and process hollowing, and see if we can capture the decrypted/decompressed/newly written memory. Let’s spruce up a tad. Continue Reading

To analyse the cna12 MySQL attacks, I had to install MySQL Express Server as the attacks were prematurely exiting when connecting to Dionaea. Extracting the binary files from the libpcap files was annoying, so I decided to change Dionaea so that it would automatically extract the binary files used in the cna12 attacks. Continue Reading
