Starting to work on another blog post for this activity

Thanks to these folks who helped find these and are always encouraging! @securitydoggo @James_inthe_box @_jsoo_

The decoded portion of the CVE-2017-11882 is "cmd /c start %TEMP%\jjjjjjjjjjjjjjjjjjj.j" which runs the executable and shows a messagebox with the word "Hacked".

Example: 5c68c0a32a8c59271afe3456430125f77b02b240fe578da6b7f398656f6cf972 This is an early test using a small executable named "jjjjjjjjjjjjjjjjjjj.j".

How it works Apparently embedded objects get stored in %temp% while the document is open and they use the original name. That gives us a method of "dropping" a known file to a known location. CVE-2017-11882 gives us a method of executing it.

We have recently found samples in the wild using a new method involving CVE-11882 that effectively makes it a dropper. Apologies if someone has already put this out but we haven't seen it and believe it is important. @blu3_team @ImPureMotion
