Cybercriminals stole $2.7 billion in crypto this year, a new record for crypto-stealing hacks, according to blockchain-monitoring firms. Once again, in 2025, there were dozens of crypto heists hitting several cryptocurrency exchanges and other web3 and decentralized finance (DeFi) projects. The biggest hack by far was the breach at Dubai-based crypto exchange Bybit, where hackers stole around $1.4 billion in crypto. Blockchain analysis firms, as well as the FBI, accused North Korean government hackers — the most prolific group targeting crypto in the last few years — of this massive heist. This was the largest known loot of crypto of all time, and one of the largest financial heists in the history of humanity. Before the Bybit hack, the largest crypto thefts netted $624 million and $611 million for hackers in the 2022 breaches against the Ronin Network and the Poly Network, respectively.

Full report : Chainalysis and TRM Labs estimate that $2.7B was stolen in crypto in 2025 in total, up from $2.2B in 2024; the biggest hack was the $1.4B breach at Bybit.
