In the first half of 2025, losses from crypto hacks and scams reached $2.47 billion, according to a report by CertiK. However, the second quarter saw a decrease in the overall number of attacks.
Overview of Losses
In the first half of 2025, total losses exceeded $2.47 billion, which is a 3% increase over 2024 figures. In the second quarter, the total loss amounted to over $800 million across 144 incidents, reflecting a 52% drop compared to the first quarter.
Major Incidents in H1 2025
The bulk of losses was attributed to two incidents – the hack of crypto exchange Bybit and the Cetus Protocol attack, resulting in a combined loss of $1.78 billion. Notably, the Bybit attack occurred on February 21, with $1.5 billion in Ether stolen, while Cetus Protocol was hacked for $225 million on May 22.
Surge in Phishing Attacks and Need for Enhanced Security
Phishing attacks have emerged as the most common type of security threat this year, with 132 incidents and losses totaling $410 million. CertiK recommends users adopt enhanced security measures, avoid unknown links, and enable multifactor authentication.
Despite the significant losses from crypto hacks, the CertiK report emphasizes the need for improved security standards in light of growing interest in crypto investments and legislative changes.
