Crypto security — hacks, exploits, and post-mortems

Smart-contract exploits, bridge hacks, phishing campaigns, and exchange breaches cost the crypto industry billions every year. Our security coverage reports each major incident as it surfaces — root cause where known, on-chain forensic trails, attacker addresses, fund flows through mixers and bridges, recovery efforts, and post-mortems published by the affected protocols and audit firms. We also follow the white-hat ecosystem, bug bounty programs at Immunefi and Code4rena, ongoing audits, and the security-tooling vendors (formal verification, runtime monitoring) working to reduce the next breach.
