Sui Targets Network Security After Cetus Protocol Breach

Sui Foundation has announced a commitment to enhance security measures following the breach on its network’s Cetus Protocol on May 22, 2025.

The hack underscores security vulnerabilities, leading Sui Foundation to allocate $10M for network protection. The breach revealed ecosystem weaknesses, creating urgency for technological upgrades.

The recent breach on the Sui blockchain’s Cetus Protocol saw $223 million in crypto assets compromised. Prompt action by Sui network validators led to the freezing of $162 million, underscoring the coordinated security response.

Cetus Protocol served as a core component within the Sui ecosystem, supporting over 62,000 users. Following the breach, Dedaub’s investigation uncovered vulnerabilities exploited by attackers to drain liquidity pools via spoof token manipulation.

“The attacker exploited vulnerabilities in Cetus Protocol’s smart contracts by deploying spoof tokens to manipulate price curves and reserve calculations. This allowed them to extract real assets from multiple liquidity pools, including the SUI/USDC pool.” — Deddy Lavid, CEO, Cyvers

The attack impacted various stakeholders, leading to a 14% drop in the SUI token’s value. Liquidity pools held by Cetus also saw significant depletion, affecting broader market stability.

Financial implications extend beyond immediate losses. The incident highlighted ongoing security challenges within the crypto and Web3 industry, prompting calls for increased regulatory scrutiny and protective measures.

Longer-term outcomes may include strengthened regulatory frameworks and advancements in blockchain security protocols. Industry experts advocate for robust defenses to mitigate such risks and enhance trust within decentralized finance ecosystems.
