Data: In 2025, cryptocurrency hackers stole $3.3 billion, but the number of attacks decreased by 162 compared to the previous year

According to CoinTelegraph, data from blockchain security company CertiK shows that cryptocurrency hackers stole $3.3 billion in 2025, with supply chain vulnerabilities becoming the most destructive threat, causing losses of $1.45 billion in just two incidents. The average loss per hacking incident was $5.3 million, a 66% increase from the previous year.

However, the data also shows a sharp decline in the number of security incidents, with 162 fewer incidents year-on-year, indicating that protocol-level security is improving, forcing attackers away from simple code vulnerabilities and towards phishing and infrastructure-level attacks. The report states that phishing scams have become the second largest threat, with cryptocurrency investors losing a total of $722 million across 248 incidents.
