Is OllyDbg Version 2 Ready for Malware Analysis?

Many malware reverse-engineers consider OllyDbg a valuable part of their toolkit. The latest version 1 release of this powerful debugger has been showing its age. Fortunately, version 2.01 seems to be sufficiently mature to start displacing its predecessor as part of the malware analysis workflow. Here's what you can expect when starting to experiment with OllyDbg version 2.01. Continue reading Is OllyDbg Version 2 Ready for Malware Analysis?


Dealing with ASLR When Analyzing Malware on Windows 8.1

If you're migrating your malware lab from Windows XP, watch out for the forced ASLR feature of the operating system, especially when using Windows 8.1. ASLR is good for security, but it complicates malware analysis efforts. IDA Pro, OllyDbg, UPX and other tools could get confused. Here is how to get around these issues. Continue reading Dealing with ASLR When Analyzing Malware on Windows 8.1


The Many Fields of Digital Forensics and Incident Response

As the world of information technology grows in size and complexity, sectors within the IT industry become more and more specialized. Within IT, information security used to be considered niche. Nowadays, saying that your're an infosec professional positions you as somewhat of a generalist. After all, within the infosec field there are several specialization areas, including compliance, pen testing, application security. Even within the area of digital forensics and incident response, many sub-fields have emerged, as discussed in this post. Continue reading The Many Fields of Digital Forensics and Incident Response


Reverse-Engineering Malware Course Expanded to Include Capture-the-Flag Challenges

SANS expanded the Reverse-Engineering Malware course (FOR610) to include a day's worth of capture-the flag malware analysis challenges. The challenges are built upon the NetWars tournament platform and are designed to reinforce the skills learned earlier in the course by experimenting with real-world malware. You can get a sneak peak at the new experience. Continue reading Reverse-Engineering Malware Course Expanded to Include Capture-the-Flag Challenges


Tools for Examining XOR Obfuscation for Malware Analysis

There are numerous ways of concealing sensitive data and code within malicious files and programs. Fortunately, attackers use one particular XOR-based technique very frequently, because offers sufficient protection and is simple to implement. Here's a look at several tools for deobfuscating XOR-encoded data during static malware analysis. Continue reading Tools for Examining XOR Obfuscation for Malware Analysis
