Palo Alto’s Unit 42 has investigated several incidents linked to the Luna Moth group callback phishing extortion campaign targeting businesses in multiple sectors, including legal and retail. The analysis discovered that the threat actors behind the campaign leverage extortion without malware-based encryption, have significantly invested in call centers and infrastructure unique to attack targets, and are evolving their tactics over time. Unit 42 stated that the campaign has cost victims hundreds of thousands of dollars and is expanding in scope.
