What is the matter?
The Microsoft Security Response Center (MSRC) has published guidance for customers about DoppelPaymer ransomware attacks.
- The warning reads that there is misleading information circulating online states that the ransomware spreads via BlueKeep. Microsoft's research team did not find any evidence of this.

“Security administrators should view this threat as additional motivation to enforce good credential hygiene, least privilege, and network segmentation,” says the warning.
