- Hackers stole $257M from Cetus and others.
- SUI froze $162M promptly.
- Cetus DEX suffered largest, $230M, exploit.
Hackers targeted several cryptocurrency platforms in May 2025, leading to $257 million in stolen funds, with $162 million recovered primarily on the SUI protocol.
Cetus Protocol DEX
Cetus Protocol DEX suffered a $230 million loss due to smart contract vulnerabilities. The incident represents the largest single exploit in May 2025 marked by rapid intervention.
The SUI protocol promptly responded by initiating an emergency vote to freeze $160 million of impacted assets. Community governance led to successful recovery efforts on the blockchain.
The hacks impacted multiple stakeholders across industries, resulting in affected investors and platforms. Market reactions were swift, with rapid asset price fluctuations, particularly for SUI tokens.
The events had financial implications with disrupted operations, heightened scrutiny on security measures, and community-led regulatory discussions on decentralized exchange vulnerabilities.

Historic precedent reveals a pattern of similar attacks on decentralized financial structures with variable recovery success. Industry-wide security improvements remain crucial.
Experts predict enhanced security measures will follow, potentially leading to stricter protocol audits and innovative technological adaptations to fortify existing systems against cyber threats.
