Dan Saunders, senior incident reaction expert at NTT, mentioned that the malware’s look adopted productive privilege escalation and lateral movement applying harvested compromised qualifications. The malware also has a link with DoppelPaymer.

“This is of importance, as at this phase, in parallel inside the network targeted visitors, we observed command and management (C2) infrastructure communication affiliated with DoppelPaymer,” said Saunders.
