Advanced Malware VBA Stomping – What’s New in 2019

There are powerful malicious document generation techniques that are effective at bypassing anti-virus detection. A technique which we call “VBA stomping” refers to destroying the VBA source code in a Microsoft Office document, leaving only a compiled version of the macro code known as p-code in the document file. Maldoc detection based only on the VBA source code fails in this scenario. Reverse engineering these documents presents significant challenges as well. Come find out what is new with VBA Stomping since our presentation on the topic last year.
