According to ChainCatcher news and a report by CoinTelegraph, data from the blockchain security company CertiK shows that crypto assets hackers stole 3.3 billion dollars in 2025, with supply chain vulnerabilities becoming the most destructive threat, causing losses of 1.45 billion dollars in just two incidents. The average loss amount per hacker attack was 5.3 million dollars, a rise of 66% compared to the previous year. However, data also shows that the number of security incidents has sharply decreased, down by 162 compared to last year, indicating that protocol-level security is improving, forcing attackers away from simple code vulnerabilities and instead engaging in phishing and infrastructure-level attacks. Reports indicate that phishing scams have become the second biggest threat, with cryptocurrency investors collectively losing $722 million in 248 incidents.
