Researcher creates workaround for Microsoft Defender security patch
Brief
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.
But the proof of concept (PoC) security workaround, ShieldBreak, described by Nightmare Eclipse in a series of public posts , potentially threatens to be more damaging than earlier workarounds.
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.
