In a devastating week for cryptocurrency security, major exchanges Coinbase and Cetus have suffered significant security breaches, with combined losses and potential damages exceeding $623 million. These incidents highlight growing concerns about centralized exchange vulnerabilities and underscore the importance of self-custodial solutions.
Cetus AMM Exploit Results in $223M Loss
On May 22, hackers exploited a critical vulnerability in Cetus’s automated market maker (AMM) protocol, successfully draining $223 million in digital assets within 24 hours. The attack, which targeted a flawed overflow check in the protocol’s smart contracts, allowed malicious actors to establish oversized positions with minimal initial capital. This incident has particular significance as it connects to the broader shift in DeFi dominance away from Ethereum, highlighting security challenges facing emerging blockchain platforms.

- Partial social security numbers
- Government ID images
