币界网报道：Crypto investors suffered record losses exceeding $2.1 billion from hacks and exploits in H1 2025, with North Korean-linked groups responsible for $1.6 billion (70%) of stolen funds, according to TRM Labs. The surge includes February's historic $1.5 billion Bybit hack attributed to North Korea, doubling the average hack size to $30 million compared to 2024. State-affiliated attacks expanded beyond North Korea, with Israel-linked Gonjeshke Darande stealing $90 million from Iran's Nobitex exchange in June - sending funds to unspendable addresses suggesting political motives. Infrastructure-level breaches (private key thefts, front-end hijacks) accounted for 80% of losses, proving ten times more profitable than smart contract exploits, while traditional DeFi vulnerabilities represented just 12% of damages.
