What happened
Collection of security news: a new GPU rowhammer technique against Nvidia Ampere cards produces GDDR bitflips that can corrupt CPU memory and yield full host compromise when the IOMMU is disabled (default BIOS setting). Google TAG disclosed DarkSword, a multi-zero-day iOS full‑chain exploit used by suspected state actors. Researchers uncovered Fast16, a likely state‑sponsored sabotage malware predating Stuxnet. Anthropic’s Claude/Mythos AI tooling has autonomously found and weaponized large numbers of software vulnerabilities (Firefox fixes included 271 issues), raising concerns about AI‑driv
