Frankenstein

Also known asFrankenstein

Frankenstein is a named threat actor/campaign referenced in the provided content. The content states that Frankenstein has used spearphishing emails to deliver trojanized Microsoft Word documents. On compromised systems, the actors used PowerShell to run a series of base64-encoded commands that acted as a stager and enumerated hosts. They also used Empire to obtain the compromised machine's name, and used WMI queries to determine whether analysis tools were running on the system. The content further states that Frankenstein communicated with command-and-control infrastructure via an encrypted RC4 byte stream and AES-CBC. The name "Frankenstein" also appears in ATT&CK-style tags/group-change references and in detection categorization related to CVE-2017-11882, but no additional high-confidence attribution, targeting, aliases, or subgroup information is provided in the supplied content.
