Rich and Greg in Va. – Ghillie Suits, AR-15’s, Russian Ammunition and Chinese Malware

The morning was spent discussing how lame Conficker.C turned out to be and how it was most likely just barrage jam… meaning a smoke screen diversion to throw off the scent for the “real” slow and low pdf attacks that were slipping into financial institutions in droves. Then on Friday morning HBGary was lucky enough to receive a nice excel spear phishing attack. Unlike most companies we love this stuff. This gives us something to do over the weekend. Greg and I also discussed our new global services offerings which will soon appear on our web site.

After breakfast Greg and I went to an undisclosed location in the Northern Virginia area, got suited up with Ghillie-Suits, AR-15’s, and a 1000 rounds of Wolf Performance Ammunition from Russia. Our mission was to get from point A to point B without getting caught by numerous “individuals”. If we weren’t caught and we made it to point B, we were then to shoot the 500 rounds each at targets from 25 yards up to 100 yards. We had up to 4 hours to cover the terrain, get to Point B, shoot our rounds and get back to point A. without getting caught; again the main point was not getting caught. It was a great! We covered a crazy amount of territory in a short period of time climbing through all kinds of thick brush and most of it was straight up hill to reach point B. At one point we we’re within 50 yards of some of the “individuals” but remained completely still and since we were in our Ghillie-Suits we remained completely still and remained undetected, just like a good rootkit. ;) We ultimately made it to Point B., where we celebrated by drinking some water and dropping our packs to load our rifles. We target practice with Russian ammunition because it’s cheap, pretty reliable and readily available.

As the sun was setting, we had already infected a VM with one of the recent boobytrapped PDF documents. Using a snapshot and Flypaper, we extracted several binaries with Responder and discovered a running botnet out of Russia. The PDF document immediately grabs a malware loader executable from a hacked chinese website, including a flash module. Once the loader executes, the main loader contacts a bot controller located in the ukraine, and the subsequent payload that is downloaded loads a kernel mode rootkit and a usermode module that communicates with a single drop point - a single commercial hacked website to store a drop point, and from this scripted location, data being emailed to a completely different and single hacked email account. The bot control software is something called "JRoger BManager v1.5" and in this case, was operated from a Russian language asset. We made heavy use of NetWitness Informer to capture C&C traffic and compressed downloads of infection modules. We are now tracking this threat to learn more.

Here are some pics:

NetWitness really boils off the fat. You can slice and dice the data from a packet capture in so many ways. Here are shots:

Overall a good day.
