Description of Campaign
The Lazarus APT threat group targeted users looking for career opportunities in the defense sector with phishing emails containing malicious attachments. The macro-embedded documents appeared to come from Lockheed Martin and communicated with command and control servers located on GitHub. Successful infections resulted in the exfiltration of sensitive information to the C2 servers.

Our ATR Team gathers and analyzes information from multiple open and closed sources before disseminating intelligence reports. This campaign was researched by Malwarebytes and shared publicly.

Minimum set of Manual Rules to improve protection to block this campaign:

IMPORTANT: Always follow best practices when you enable new rules and signatures.

When you implement new rules or signatures, always set them to Report mode first and check the alerts generated. Resolve any issues that arise and then set the rules to Block. This step mitigates against triggering false positives and allows you to refine your configuration.
