# 2026 crypto hack surge (H1-H2) > Live situation record from CLSTR: https://clstr.news/situations/2026-cryptocurrency-hack-surge > Updated: 2026-09-08T14:13:40.000Z. Sources: 49. Developments: 13. The first half of 2026 saw a record rise in cryptocurrency-related attacks, with 207 incidents resulting in approximately $972 million stolen—more than double the 83 incidents recorded during the same period in 2025. North Korean-affiliated groups were major contributors, responsible for roughly 66% of stolen funds, totaling nearly $643 million. Attack vectors have evolved to include smart contract vulnerabilities, private key theft, and sophisticated social engineering. Notable exploits include the $295 million Drift Protocol attack on Solana and the KelpDAO breach. Additionally, the sector faced risks from data leaks, such as a reported sale of data belonging to 2.3 million French cryptocurrency holders. By August 2026, the landscape shifted toward more frequent but smaller-scale attacks. According to PeckShield, August saw a record 50 major security incidents, a 67 percent increase from July. However, total monthly losses dropped to approximately $136.3 million, a 49 percent decline from the $270 million lost in July. This decline was driven by a sharp drop in the average loss per incident, from $9 million to roughly $2.7 million. One significant event involved an attack on the Tectonic lending protocol on the Cronos network, where attackers attempted to extract roughly $74 million via governance token manipulation. Cronos validators halted block production after approximately $6 million was bridged to Ethereum, subsequently restoring the network to a state prior to the attack to trap the majority of the assets. Recent analysis by CoinGecko reveals that between January 2025 and July 2026, cryptocurrency platforms lost more than $3.63 billion to cyberattacks and access key thefts. A significant finding indicates a gap in current security measures: approximately 88 percent of stolen funds originated from platforms that had completed independent security audits, and roughly 60 percent of affected platforms had undergone such checks. ## Claims - The largest single exploit was KelpDAO, resulting in a loss of about $292 million.
