What We Know

CISA has confirmed that a high‑severity Microsoft Defender vulnerability tracked as BlueHammer (CVE-2026-33825) is being used in live ransomware campaigns. Multiple security outlets report the agency added the flaw to its Known Exploited Vulnerabilities catalog and warned that ransomware gangs are exploiting the bug to compromise Windows systems.

Reporting indicates attackers are leveraging the flaw to disable Defender’s protections and achieve remote code execution or elevated privileges (reports reference execution of arbitrary code and gaining SYSTEM-level access). The advisory and contemporaneous coverage (published around July 1, 2026) characterize the activity as active exploitation by criminal groups rather than only theoretical research or proof‑of‑concept work.
