System Binary Proxy Execution and a Spearphish Payload

Adversaries can execute an attack by embedding malware into a document, attaching that document to an email, crafting the email message to entice the target, and then sending the email to the target.

The first technique we cover, Spearphishing Attachment, is generally one of the first steps in an attack process. By this point, the adversary has already performed some reconnaissance and resource development.

The primary risk associated with the second technique we cover, Compiled HTML File, is the execution of unauthorized/malicious code without detection, and any subsequent impacts. For the purpose of this course, it will be observed as a file contained in an email attachment associated with a Spearphishing Attachment as part of an Initial Access attempt.

Learn how to detect and mitigate these techniques to protect your organization from this type of attack.

Apply what you learn and get the hands-on skills you need in Cybrary's MITRE ATT&CK Framework courses aligned to the tactics and techniques used by the threat group APT41 (aka Double Dragon). Prevent adversaries from accomplishing the tactic of initial access.
