OKX has reactivated its decentralized exchange (DEX) aggregator, OKX Web3, with significant security upgrades after a temporary shutdown due to misuse by the North Korean hacking group, the Lazarus Group. The platform now features a real-time abuse detecting and blocking system, enhanced onchain analysis tools, and a dynamic database to identify and block suspect addresses. These measures aim to prevent fraudulent activities, backed by audits from blockchain security firms like CertiK, Hacken, and SlowMist.
