84 malicious @tanstack versions across 42 packages in six minutes is how fast OIDC trusted publishing can turn from assurance into blast radius. Crypto saw the user-facing version with Ledger Connect Kit: a poisoned JS dependency hit legit dapp frontends and stole roughly $600k because wallets signed what the dependency put in front of them.
