The hackers stole more than $ 2.47 billion in cryptocurrency in the first half of 2025, already exceeding the total of $ 2.42 billion from last year, according to Certik’s Hack3D report.
The majority of this figure can be assigned to two incidents; The violation of the appeal and the feat of the Cetus protocol which combined at a value of $ 1.78 billion.
Wallet’s compromise was the main stakeholders’ attacks in the first half of this year, contributing to $ 1.7 billion in losses, while phishing was still endemic, which resulted in $ 410 million of 132 incidents.
Phishing is a technique that hackers use to steal the password or the identification information of a victim in order to access an account.
“Although the overall figures are alarming, it is important to emphasize that the majority of funds lost in H1 were attributable to two concentrated and high impact events,” said Certik co-founder Ronghui Gu.
“But whatever, the results remind industry that there is still a lot of work to do,” added Gu.
