What happened

Aggregation of multiple high-impact security stories in April 2026: a targeted supply-chain compromise hitting security firms (Checkmarx, Bitwarden); an npm/open-source package (element-data) exfiltrating credentials; a high-volume credential-theft campaign and widespread router compromises attributed to Russia; Iran-linked attacks disrupting US critical infrastructure and a maritime crypto-scam tied to a ship attack; new GPU Rowhammer variants (GDDRHammer/GeForge/GPUBreach) enabling full system compromise on machines with Nvidia GPUs; ransomware families experimenting with post‑quantum crypts
