Microsoft has been investigating recent attacks by malicious actors using the Dopplepaymerransomware. There is misleading information circulating about Microsoft Teams, along with references to RDP (BlueKeep), as ways in which this malware spreads. Our security research teams have investigated and found no evidence to support these claims. In our investigations we found that the malware relies on remote human operators using existing Domain Admin credentials to spread across an enterprise network.
