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.

About Security coverage on CoinArticle

Are stolen funds typically recovered?
Sometimes. White-hat counter-exploits, negotiated bounty returns, exchange freezes, and law-enforcement seizures recover a meaningful share of stolen funds in some incidents — but a large fraction still ends up laundered through mixers, cross-chain bridges, or off-ramped via OTC desks. Recovery details are reported as they emerge.
How often is this section updated?
Our pipeline runs every hour, so newly clustered stories typically appear within an hour of being published by the source outlets. We deduplicate, merge related coverage, and tag every article with categories, sentiment, and impact scores.
Where does the reporting come from?
Each article is an AI-merged synthesis of multiple primary sources — major crypto publications such as CoinDesk, Cointelegraph, The Block, Decrypt, Bitcoin Magazine, CryptoSlate, The Defiant, and Blockworks. Original-source URLs are listed at the bottom of every article so you can verify every claim against the primary reporting.
