币界网报道：[TRM Labs: $2.1 billion in cryptocurrency stolen so far this year, of which private key vulnerabilities and front-end protocol attacks account for 80%] According to a report by Bijie.com, blockchain intelligence company TRM Labs said that in the first half of 2025, the cryptocurrency losses caused by attacks reached $2.1 billion, most of which were caused by the leakage of encrypted private keys and front-end intrusions. TRM Labs released a report on Thursday stating that more than 80% of the stolen funds in the 75 cryptocurrency hacking incidents that have occurred so far this year came from so-called infrastructure attacks. This type of attack takes away 10 times more funds than other types of attacks on average. Infrastructure attacks target the technical backbone of the system with the goal of gaining unauthorized control, misleading users, or redirecting assets. They include hijacking the private key mnemonics of crypto wallets or exploiting the user interface part of the crypto protocol (i.e., the front end).
