Wepawet: analyzing web-based malware

Hello guys!

Wepawet is a new service for detecting and analyzing web-based malware. It currently handles Flash and JavaScript files.

Things you can do with Wepawet:
- Determine if a page or file is malicious
- wepawet runs various analyses on the URLs or files that you submit. At the end of the analysis phase, it tells you whether the resource is malicious or benign and provides you with information that helps you understand why it was classified in a way or the other.
- wepawet displays various pieces of information that greatly simplify the manual analysis and understanding of the behavior of malicious samples. For example, it gives access to the unobfuscated malicious code used in an attack. It also collects the URLs accessed by a sample.
- wepawet does not just tell you that a resource is malicious, it also shows you the exact vulnerability (or, more likely, the vulnerabilities) that are exploited during an attack.

What do you consider to be the most important security issue for 2009?

I'm completing some research on what we feel will be the most important security issues in 2009. Please take a minute to respond to our poll.

BIOS Malware/Rootkit Anyone?

| |

Has anyone ever touched / seen / heard of an actual BIOS malware implementation? I've only read of malware that writes random data to the BIOS ROM.

I am guessing the BIOS manufactures' implementations are too ambiguous for any generic infection method to work such as the methods used on PE / ELF / Boot sectors.

Q about reverse engineering tools people use


I'm curious about what sorts of tools people use to automate the proces of reverse engineer malware binaries. I'm reasonably familiar with disassemblers (for static analysis), and emulators/VMs and debuggers (for dynamic analysis). The obvious problem is that static analyses are susceptible to various sorts of binary obfuscations, while dynamic analyses would seem to be susceptible to various sorts of anti-monitoring defenses, time bombs, logic bombs, etc.

Collaborative Security against Malware and Botnets


Hi guys,

I am a researcher working on Botnets and Malware. In the previous months I have been studying Storm. What I have learned from this experience was really useful, but I have also seen that there is a lot of improving to be done in the way Malware and Botnets are fought.

Malware Challenge


Participants should download the malware sample and analyze it. The end result should be a document containing details on the analysis performed. The analysis document can be written in any form, but the questions and statements beow should be answered within it. Participants should note what questions are being answered.

All the rules here:
