TRM Labs: $2.1 Billion in Cryptocurrency Stolen So Far This Year, with Private Key Vulnerabilities and Front-End Protocol Attacks Accounting for 80%

According to a report by Jinse Finance, blockchain intelligence firm TRM Labs stated that in the first half of 2025, cryptocurrency losses due to attacks reached as high as $2.1 billion, with the majority resulting from crypto private key leaks and front-end breaches. In a report released on Thursday, TRM Labs noted that of the 75 cryptocurrency hacking incidents so far this year, over 80% of stolen funds stemmed from so-called infrastructure attacks. On average, these attacks result in ten times more stolen funds than other types of attacks. Infrastructure attacks target the technical backbone of systems, aiming to gain unauthorized control, mislead users, or redirect assets. These include hijacking the mnemonic phrases of crypto wallets or exploiting the user interface components (i.e., the front end) of crypto protocols.
