Cetus Offers $5 Million Bounty After $223 Million Exploit on Sui Blockchain: Urgent Call for Crypto Security

• Cetus, a leading DEX on Sui, offers $5M bounty for hacker behind $223M exploit
• $162M of stolen funds frozen; Cetus seeks return of 20,920 ETH and all Sui assets
• Hack exploited AMM liquidity parameters; Cetus vows to re-audit and enhance security

Can a $5 million bounty stop a $223 million crypto heist? That’s the pressing question facing Cetus, a leading decentralized exchange (DEX) and liquidity protocol on the Sui blockchain. On May 22, 2025, Cetus was rocked by a massive exploit, losing a staggering $223 million. In response, they’ve placed a $5 million bounty on the head of the hacker—a sum that could buy you a small island or, at the very least, a very fancy yacht.

Before diving into the nitty-gritty, let’s get something straight: Cetus isn’t just any DEX. It’s a pivotal liquidity provider on the Sui network, a blockchain designed for high-performance and scalable decentralized applications. So, when Cetus gets hit, it’s not just their problem—it’s a jolt to the entire Sui ecosystem.

The Hack Details

The exploit zeroed in on a vulnerability in Cetus’s automated market maker (AMM), specifically an error in the most significant bits (MSB) check. For those new to the crypto jargon, an AMM is like a self-regulating vending machine for tokens. The MSB refers to the leftmost bits in a binary number, which carry the most weight. The hacker exploited this flaw to manipulate values, add massive liquidity positions with minimal token input, and then drain multiple pools using flash swaps. Think of flash swaps as lightning-fast transactions that can be executed and reversed within a single blockchain transaction, often used to exploit liquidity pools. Cetus caught wind of the hack within 10 minutes and hit the pause button on trading while rallying Sui validators to freeze the attacker’s wallets.

Cetus’s Response

After failing to sweet-talk the hacker into a white hat deal, Cetus ramped up its response with a vengeance. They’ve managed to freeze $162 million of the compromised funds and are now urging the hacker to return over 20,920 Ethereum and all frozen assets on Sui. If the hacker plays nice and complies, Cetus is ready to drop all legal actions, including the bounty. It’s like a crypto version of ‘Wanted: Dead or Alive’ with a merciful twist.

The bounty is backed by Inca Digital and the Sui Foundation, with the latter holding the purse strings. Cetus is calling on the crypto community to help identify the hacker, asking for their name, location, and proof of identity. It’s a classic case of the crypto world banding together to tackle a common enemy.

“We have not received any communication from the hacker. We encourage the hacker to sincerely consider our offer terms,” Cetus wrote in an update on X. “Simultaneously, with the support of Inca Digital and financial support from Sui Foundation, we are announcing a bounty of $5M for relevant information that results in the successful identification and arrest of the hacker(s).”

“If the hacker should cooperate and accept our offer as we hope, we will refrain from pursuing any further legal action or recourse, including the $5m bounty.”

Impact on Sui Ecosystem

The ripple effects of the hack have been felt across the Sui ecosystem. The total value locked (TVL) on the Sui network plummeted from $2.13 billion to $1.92 billion, and the CETUS token price took a nosedive by 40%. Even the rock-solid USD Coin (USDC) temporarily lost its dollar peg due to the liquidity loss. It’s a stark reminder of how a single exploit can send shockwaves through an entire blockchain.

Cetus’s Recovery and Future Plans

Cetus isn’t sitting on its hands. They’re laser-focused on recovery, planning to re-audit their contracts, beef up their monitoring systems, and team up with ecosystem partners on a liquidity recovery plan. They’re also pushing Sui validators to throw their weight behind on-chain votes to help users recover lost funds. It’s a comprehensive approach to not only catch the hacker but also to rebuild trust and resilience in the platform.

These steps include implementing more robust code checks, as underscored by Dedaub, a blockchain security firm. Industry leaders have sounded the alarm that without proactive measures, these hacks could pave the way for regulatory crackdowns. Some in the community have applauded the swift action of Sui validators, while others have raised eyebrows, questioning whether freezing funds goes against the very grain of decentralization.

Broader Implications for Crypto Security

This hack isn’t just a blip on the radar; it’s part of a worrying trend of escalating cybersecurity exploits in the crypto world. While Bitcoin and blockchain technology promise a future of financial freedom and innovation, they’re not immune to the dark side of human ingenuity. The crypto world must keep evolving, juggling the ideals of effective accelerationism (e/acc) with the gritty realities of cybersecurity.

As platforms like Cetus navigate these turbulent waters, the entire blockchain ecosystem must stay on high alert and proactive in their security measures. While we champion the ideals of decentralization and financial revolution, we must also confront the harsh realities head-on, ensuring that the future of finance remains both innovative and secure.
