What happened
This collection highlights multiple high-impact security stories: a new Rowhammer technique against NVIDIA Ampere GPUs that flips GDDR bits to gain control of host CPU memory and achieve full system compromise (requires IOMMU to be disabled, which is the BIOS default in many systems); DarkSword, a multi-zero-day iOS full-chain exploit used by commercial surveillance vendors and suspected state actors to fully compromise devices; disclosure that AI tools (Anthropic’s Claude Mythos) can autonomously find and weaponize large numbers of vulnerabilities (Mozilla used AI to find 271 security issues,
