Cetus Crypto Exchange Drained of $223 Million in Latest Major DeFi Breach

The decentralized finance (DeFi) platform Cetus has become the latest victim in a string of major crypto heists, with attackers siphoning off approximately $223 million in a brazen exploit early Thursday.

 

Cetus, which runs on the Sui blockchain, temporarily suspended operations as the situation unfolded, initially informing users of an unspecified incident before later confirming the scale of the loss. “We took immediate action to lock our contract, preventing further outflows,” the company stated. They added that $162 million in assets have been frozen, though details on how those funds were “paused” remain unclear.

 

The platform has launched an investigation in collaboration with the Sui Foundation and other blockchain partners in an effort to recover the remaining funds. A full post-mortem has been promised.

 

Preliminary blockchain analysis reveals that around $50 million in stolen tokens has already been funneled into new digital wallets — a move experts warn may complicate recovery efforts.

 

While the exact mechanics of the breach are still under scrutiny, conflicting theories have emerged. Some users pointed to potential protocol vulnerabilities discussed in Cetus’ Discord channel, while others suggested the attacker executed a sophisticated price manipulation scheme to drain funds.

 

Cetus, which boasted $50 billion in trading volume as of April, has now joined a growing list of platforms compromised in 2025 — a year already marred by costly crypto breaches. Just this week, Coinbase confirmed a breach affecting nearly 70,000 users, and in February, North Korean hackers were blamed for the $1.4 billion theft from Bybit.

 

According to Chainalysis, over $2 billion in cryptocurrency was stolen in 2024 alone, and 2025 appears to be following that dangerous trend.

 

As DeFi continues to grow, experts say the Cetus breach is yet another reminder of the ecosystem’s security fragility — and the steep cost users may pay for it.
