Exploring Prefetch Files

One of the first things I look at when performing forensics on a system is the prefetch files which gives a report about recently run software on the system. Some malwre now recognize the importance of these files and delete them when they run.

For cases where there is still prefetch files there is a great open source tools to parse them and convert the output to a useable format.

MALTRAIL - Malware Network Sensor

There is a github project to build a network based malware detection system. This system uses blacklist and other open source information to build up a scoring system for network traffic that indicates the presence of malware.

I have not tested this system yet, however we are in the process of bringing in new equipment which frees up some older equipment to run tests on.

Analyze Volume Shadow Copies

Back in December, Harlan Carvey posted a blog about the use of tools to analyze Volume Shadow Copies to uncover historic information about the operations of a system.

If malware has been running for a while or the user has been performing activities of interest, then looking at the Volume Shadow Copies can aid in that investigation.

Using Python to mount a Forensics Image

The folks at Hacking Exposed have a good article about using the libraries in SleuthKit to mount image files using Python.

I have not tried this process out but I can image an automates tool which would make use of these libraries.
