According to ChainCatcher, blockchain intelligence company TRM Labs reported that cryptocurrency losses due to attacks in the first half of 2025 reached $2.1 billion, primarily caused by the leakage of private keys and front-end intrusions.

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

Infrastructure attacks target the technical backbone of systems, 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.
