Unit42 researchers have a report out on Luna Moth (aka Silent Ransom Group), a threat actor that has been engaging in callback phishing campaigns over the past months that have targeted several industry verticals.

“Callback phishing, also referred to as telephone-oriented attack delivery (TOAD), is a social engineering attack that requires a threat actor to interact with the target to accomplish their objectives.

Overview: Luna Moth

Security firm Sygnia has published a report on Luna Moth, a new threat actor that, since March this year, has been engaging in hack-and-extortion attacks. Sygnia said Luna Moth uses spear-phishing to infect victims with a remote access trojan, which it then uses to steal sensitive data that can be used in a future extortion attempt. The company reported that some extortion demands reached “millions of dollars.”
