Cybersecurity researchers from Proofpoint have uncovered a brand new, custom-built malware being used by threat actors to deliver a wide variety of specifically tailored stage-two attacks.
These payloads are capable of different things, from espionage to data theft, making the attacks even more dangerous due to their unpredictability.
The researchers, who dubbed the campaign Screentime, say it is being conducted by a new threat actor labeled TA866. While it’s a possibility that the group is already known to the wider cybersecurity community, no one has yet been able to link it to any existing groups or campaigns.
