On 06 September 2016, Wapack Labs received incident details involving a macro malware variant, that is researcher aware, and is leveraging a new method of string obfuscation. Macro based malware, one of the most prevalent malware delivery mechanisms, uses embedded macros in Microsoft Office documents to download and install malware on a victim’s machine. Over 3,600 additional samples of this variant, using the same obfuscation method, were found on Virus Total. Artifacts from these files suggest widespread targeting in various industries.
This report includes details on the new macro variant delivery mechanism and infrastructure leveraged in these attacks.
*Practitioners who rely on others to develop the malicious code, delivery mechanisms, and execution strategy (use known exploits).
