币界网报道：Cryptocurrency hackers stole $2.1 billion in H1 2025, with infrastructure attacks—including private-key thefts and front-end hijacks—accounting for over 80% of losses, according to TRM Labs. DeFi vulnerabilities, such as flash loans and re-entrancy exploits, contributed another 12%. The $1.5 billion Bybit breach, attributed to North Korea, inflated the average hack size to $30 million, doubling 2024's figures. State-linked groups, particularly from North Korea ($1.6 billion stolen) and Iran ($90 million diverted in a geopolitical incident), dominated attacks. TRM urged enhanced multi-factor authentication, cold storage safeguards, and tighter insider-threat controls, emphasizing cross-border law enforcement coordination and industry-wide collaboration to counter state-sponsored cybercrime.
