TechFlow news, OKLink's 2023 annual security incident review shows that the blockchain ecosystem experienced over 520 publicly disclosed security incidents in 2023, resulting in losses exceeding $1.7 billion—about 54% lower than the $3.728 billion lost in 2022. This decline is attributed to improvements in global regulatory frameworks and breakthroughs in on-chain security technologies. Among the incidents, 485 involved DApps, DeFi, and NFTs; 8 occurred at exchanges; 10 affected public blockchains; 9 involved wallets; and 14 were classified as other types.
Major high-loss incidents included: in March, the Ethereum lending protocol Euler Finance was hacked, losing approximately $197 million; in June, Atomic Wallet suffered a hack resulting in over $100 million in losses; in September, Mixin Network was attacked, losing $200 million; and in November, the Poloniex exchange had about $125 million stolen due to private key exposure.
In addition, social media platforms such as Twitter and Discord became hotspots for scams and phishing attacks, with 519 such incidents reported in 2023. For example, in September, Ethereum co-founder Vitalik Buterin’s Twitter account was compromised, leading to the theft of more than $690,000 worth of assets.
