Cetus Breach and North Korea Theft Led to $244 Million Crypto Losses in May

The cryptography industry lost more than $ 244 million against hacks and scams in May 2025, according to the security company Blockchain Peckshield.
Although the figure remains substantial, it marks a drop of 39% compared to the loss of $ 402 million in April, reporting a temporary slowdown in malicious activity.
Crypto hackers are now trying to frame the victims
Peckshield data show that attacks have lasted various protocols, some incidents resulting in minor violations and others involving catastrophic losses.
The biggest feat concerning the Protocol of Cetus, a decentralized exchange operating on the Blockchain Sui, which lost around $ 223 million in a single attack.

After the breach, Cetus signed up with the Validators followed to freeze certain stolen assets, which amounted to around 162 million dollars, or around 71% of the stolen funds.
Cetus recently saw his proposal to recover the frozen funds approved by the Suit Validators. This marks the start of a broader recovery process which includes the upgrading of intelligent contracts, the restoration of liquidity and the preparation of the platform for revival.
Meanwhile, another platform that saw a significant attack was the cork protocol based in Ethereum.
The attackers exploited the Ethereum markets (WSSTH), stretched out of the platform and the Ethereum markets (Weeth), flying around 3,761.8 WSSTH, valued at nearly $ 12 million. Although other markets have not been assigned, Cork has interrupted all operations to allow a complete audit.
Peckshield’s report has raised new concerns about the return of northern pirates to North Korea. According to the cabinet, these malicious actors have stolen $ 5.2 million with a single crypto trader.
The incident rekindled the fears of the attacks sponsored by the state, following a lull after the feat of $ 1.5 billion in February.
Other incidents included a feat of $ 2.2 million on mobius token contracts on the BNB channel. In this case, the attacker used a single smart contract to empty 28.5 million MBU tokens.
In the midst of growing threats, Tornado Cash, a mixture of cryptography based on Ethereum, remains the preferred tool for laundering stolen funds.

Given this, Yu Xian, co-founder of the security company Blockchain Slowmist, urged the victims to share their wallet addresses after a feat. He suggested making them public or partially censored to support surveys and avoid being wrongly identified as suspects.
According to him, pirates are using more and more different tactics to move suspicions on innocent users to complicate the surveys of law enforcement organizations.
“Some hackers today like to supervise others. You will not only suffer from the pain from stealing your funds, but also from subsequent cooperation with surveys on the application of laws … It is not pleasant to be treated as a suspect,” he added.
