SANS Internet Storm Center

I created a video for the analysis I described in my last diary entry "Simple Analysis Of A CVE-2021-40444 .docx Document".

I also cover another sample in that video, that is a bit harder to analyze (and has much lower detection rates on VT).

Remark that I always make sure that you can find the samples I analyze on Malware Bazaar too.

And here is the InQuest blog post I mention in the video: "Microsoft MSHTML Remote Code Execution Vulnerability".

The tools I use in this video: zipdump.py, re-search.py and xmldump.py.
