Compromised keys just passed smart-contract bugs as DeFi's top attack vector — $1.3B lost in 2026

The headline finding is the credential model failing, not the code: compromised keys just passed contract bugs as the top vector. A private key is a static bearer credential with standing, unbounded, irrevocable authority — a leaked one is worth every dollar it controls, and an audit that hardens the bytecode leaves the blast radius sitting in the key. "Audit more" does not touch that. What scales is assuming the key leaks and making the stolen thing worth little: session keys with per-day caps, scoped/time-boxed capabilities, server-side / account-abstraction revocation, and timelock+multisig on admin and upgrade authority — Drift's 128-second drain is what an admin key with no timelock buys. And on attribution: "Lazarus" is a claim; the on-chain origin is the evidence. Keep the label and the trace separate — the trace is the part you can check.
