In the first half of 2025, the cryptocurrency sector faced significant cyber crimes resulting in losses exceeding $2.5 billion. Data from CertiK highlights the primary sources of theft and significant incidents that occurred during this period.
Overall Losses and Sources of Theft
According to CertiK's report, total losses due to cyberattacks amounted to nearly $2.5 billion compared to $2.42 billion for all of 2024. The largest share of losses, over $1.7 billion, was attributed to compromised wallets, while phishing attacks resulted in over $410 million in theft. Code vulnerabilities accounted for losses exceeding $283 million.
Key Incidents and Their Consequences
In the first half of 2025, two major incidents accounted for about 72% of all losses: the Bybit hack and the Cetus protocol exploit. Without these two events, total losses in the first half would have been around $690 million. Incidents involving Nobitex and ALEX Lab were also significant.
Quarterly Analysis
The first quarter of 2025 accounted for $1.67 billion in losses, more than double the $801 million in the second quarter. In Q2, phishing became the most widespread attack method, causing losses of over $395 million. Despite a decrease in the number of attacks in Q2, several major incidents still resulted in significant financial damage.
The analysis of losses in the cryptocurrency sector for the first half of 2025 demonstrates that cybercrime remains a serious issue for the industry. Companies and users must remain vigilant and take measures to protect their assets.
