A standard characteristic in the entire malicious paperwork Cisco Talos took aside is the existence of 4 non-malicious VBA subroutines. These subroutines appeared in all of the samples and weren’t obfuscated. The inclusion of the benign code is prone to decrease the extent of suspicion of the code generated by MacroPack, Talos researchers suspect.
Is that this a brand new malware marketing campaign by a menace actor? Perhaps not. MacroPack is a framework created for Crimson Groups to check the defences of keen organizations, so the report says it’s doable the examples it discovered have been a part of purple teaming workout routines.
