Stresspaint Malware IOC's

One thing that continues to amaze me is that anytime something like this hits the news, IOC's are limited to what files (by name) it drops. Ya know what's even more useful? Hashes, hashes are more useful. So here's a few I was able to pull.

Note: I seem to be missing DX.exe and update.dll that were posted here. I'm not sure why I didn't see these drop, perhaps it's only periodically. If you have them, drop me a message on Twitter.
