The U.S. government updated its advisory on the Medusa ransomware group, revealing its use of access brokers and exploitation of unpatched software vulnerabilities, leading to over 500 victims since early 2025, with a focus on health and public health sectors.

◆ ◆ The Wire takeaway
You must tighten patch management and vet access brokers carefully as Medusa’s paid partnerships amplify attack reach. Securing health and related sectors is urgent because opportunistic hackers pivot fast using new exploits before patches land.
