What happened
A surge of high-risk security incidents and trends: a persistent leaker published additional Microsoft zero‑days while Microsoft shipped a Patch Tuesday with ~30 critical CVEs; malware crew TeamPCP open‑sourced the Shai‑Hulud worm; supply‑chain assaults (TanStack npm cache‑poisoning) pushed malicious packages; Foxconn and multiple enterprises reported data theft/ransomware claims (ShinyHunters, Qilin, Nitrogen). Several active Linux local‑root flaws (CopyFail, Dirty Frag) and a critical cPanel exploit are being weaponized in the wild. Increased credential/theft campaigns using fake Claude Code
