Cryptocurrency hacks surge as North Korean groups and data leaks increase risks

The cryptocurrency sector is experiencing a significant surge in cyberattacks. According to analysis by TRM Labs, 207 incidents in the first half of 2026 resulted in $972 million being stolen, more than doubling the 83 incidents recorded during the same period the previous year. North Korean-affiliated groups are identified as major perpetrators, reportedly responsible for approximately 66% of the stolen funds, totaling nearly $643 million.

Attack methods have become increasingly sophisticated. Beyond traditional private key theft, hackers are utilizing social engineering and fraudulent job offers to infiltrate technical teams. A notable incident involved the Drift protocol on Solana, which lost $295 million on April 1, 2026. While smart contract vulnerabilities remain the most frequent attack vector, the compromise of private keys often results in the largest single financial losses.

In France, security concerns have escalated following reports of a data sale on cybercriminal forums. The sale allegedly contains information on 2.3 million French cryptocurrency holders, including identities, phone numbers, email addresses, physical addresses, and estimated financial holdings. This data poses a high risk for targeted phishing, identity theft, and potential physical security threats.
