The story so far
A security researcher has published a new Windows zero-day bug after Microsoft threatened legal action. The vulnerability, dubbed ShieldBreak, allows attackers to gain system-level privileges. The researcher, known as Nightmare Eclipse, released the exploit following a dispute with Microsoft. The exploit bypasses Microsoft Defender, the company's built-in antivirus software, and grants full system access.
The exploit was published after Microsoft threatened legal action against the researcher. The company had previously attempted to patch the vulnerability, but the researcher found a workaround. The exploit has been released to the public, raising concerns about potential misuse. There is some contradiction among outlets.
Tom's Hardware suggests the vulnerability may already be patched. However, other outlets, including SecurityWeek and The Register, indicate that the exploit is still active on fully patched Windows systems. The current state of the vulnerability is unclear, with some suggesting it may already be addressed while others indicate ongoing risk.
