    Zero-day researcher Nightmare Eclipse, aka MSNightmare, published yet another Microsoft Defender proof-of-concept exploit for a zero-day dubbed ShieldCrash, which they claim will allow attackers to bypass the earlier ShieldBreak patch and read files as SYSTEM. “I might rework this later into a full SYSTEM PoC but for now I'm dropping this skeleton PoC because I'm feeling a bit lazy,” the prolific Microsoft bug hunter and thorn in Redmond's side said in their latest zero-day exploit's README. As is usual with Nightmare’s zero-day cadence, they published ShieldCrash shortly after Microsoft…

    News The Register Security18h ago7 sources

  9. Top 10 Best Server Security Solutions in 2026

    News Cyber Security News8h ago3 sources

Deploying dedicated endpoint detection and response (EDR) on servers requires balancing performance overhead with deep telemetry. Trend Micro’s server heritage still leads for hybrid estates, CrowdStrike and SentinelOne bring the strongest detection, Defender for Servers wins on Azure-centric economics and the quiet failure mode everywhere is the hypervisor nobody’s…
