Cryptocurrency losses reach $2.1 billion in the first half of 2025, with infrastructure attacks accounting for 80%

According to ChainCatcher, blockchain intelligence company TRM Labs reports that in the first half of 2025, losses from cryptocurrency attacks could reach as high as $2.1 billion, primarily due to leaked private keys and front-end intrusions.

The TRM Labs report indicates that out of the 75 cryptocurrency hacking incidents that have occurred so far this year, over 80% of the stolen funds come from infrastructure attacks. These types of attacks, on average, siphon off 10 times more funds than other types.

Infrastructure attacks target the system's technical backbone, aiming to gain unauthorized control, mislead users, or redirect assets, including hijacking cryptocurrency wallet private key mnemonics or exploiting parts of the cryptocurrency protocol user interface.
