“Epic Manchego” And My Tools

Filed under: Announcement — Didier Stevens @ 0:00

Over the last months, I’ve been quite busy working with my colleagues on report “Epic Manchego – atypical maldoc delivery brings flurry of infostealers“: we’ve tracked an actor creating a new type of malicious Office document.

To help with the automatic analysis of all the maldocs produced by this actor (several per day), I added new features to existing tools and created new tools.

I’m releasing this work in the coming months (some has already been published: oledump.py and zipdump.py).

    The VBA is very efficient

  3. Are the samples available somewhere to test existing protection tools on the local Webserver?

  4. Yes, all of the samples are on VirusTotal. And many samples are also available on malware bazaar (free download, no subscription). The samples’ hashes are listed in our report.
