For the past year, the ransomware conversation has centered on concentration: a handful of dominant RaaS operations controlling most of the damage, and a shrinking pool of active groups fighting over the same territory. The State of Ransomware Q2 2026 report from Check Point Research shows that picture starting to shift. The leaders are still winning, but […] The post The State of Ransomware Q2 2026 appeared first on Check Point Research. Vendors: Google, HPE, Check Point. DORA relevance: high.

Just weeks after Microsoft patched a critical hole in Microsoft Defender, a cybersecurity researcher has posted an apparent bypass that provides system-level control to attackers once they gain any level of access. The researcher, who goes by the name Nightmare Eclipse, has been engaged in a long-running battle with Microsoft Security. Nightmare Eclipse has not provided the further details we requested, however Microsoft sent a brief statement, saying, “Microsoft is aware of the reported vulnerability and is actively investigating the validity and potential applicability of these claims,” and reiterating its commitment to investigating issues and supporting coordinated disclosure. But the proof of concept (PoC) security bypass, ShieldBreak, described by Nightmare Eclipse in a series of public posts, potentially threatens to be more damaging than earlier bypass. Like other recently reported vulnerabilities, ShieldBreak requires an attacker to first somehow gain system access, typically via a successful phishing scam. Once in, however, the attacker can gain full admin/root access. But there is a troubling psychological component to ShieldBreak, in that it is a bypass for a recently posted security patch from Microsoft, noted Justin Greis, CEO of consulting firm Acceligence. The problem is that CISOs who have already deployed that patch might feel protected when they are not. “This one is concerning because the patch bypass directly calls the integrity of the remediation into question,” he said. “ShieldBreak appears to demonstrate that an attacker can bypass the fix Microsoft shipped for CVE-2026-50656 and ultimately obtain system-level privileges on the endpoint. That is an important distinction for enterprise defenders, because organizations may believe they have already remediated the underlying vulnerability. A successful patch bypass means the exposure can persist even after the normal vulnerability-management process says the system is protected.” Greis added tha CVEs: CVE-2026-50656.

Just weeks after Microsoft patched a critical hole in Microsoft Defender, a cybersecurity researcher has posted an apparent workaround that provides system-level control to attackers once they gain any level of access. The researcher, who goes by the name Nightmare Eclipse, has been engaged in a long-running battle with Microsoft Security. As of publication time, neither Microsoft nor Nightmare Eclipse has provided further details we requested.
