CertiK Security Report: Phishing attacks caused nearly $400 million in losses and became the biggest threat in Q2 2025

Odaily News Web3 security company CertiK released a report showing that Web3 security incidents in the first half of 2025 cost nearly $2.5 billion, with a net loss of $2.29 billion, exceeding the entire year of last year. Phishing attacks have become the biggest threat, with losses of about $400 million in the second quarter, accounting for half of the total losses this quarter (about $800 million), far exceeding the same period last year. Although private key leaks have decreased and code vulnerability attacks have remained at historical averages, we still need to be vigilant against major cases such as Cetus Protocol.
