Crypto-related cybercrime hit a new all-time high in 2025, with hackers stealing an estimated $2.7 billion worth of digital assets, according to leading blockchain monitoring firms.
The biggest incident was the $1.4 billion hack of Dubai-based exchange Bybit, now considered the largest crypto theft ever recorded.
Blockchain investigators and the FBI have blamed North Korean state-backed hackers, who have become the most active and successful crypto thieves in recent years.
Data from Chainalysis, TRM Labs, and De.Fi all point to the same figure: $2.7 billion stolen this year alone.
North Korean hacking groups are believed to be responsible for over $2 billion of those losses and have stolen nearly $6 billion in crypto since 2017, often to fund the country’s sanctioned nuclear program.
Other major attacks in 2025 included $223 million stolen from Cetus, $128 million from Ethereum-based Balancer, and $73 million from Phemex.
Despite better security tools, crypto hacks continue to rise, up from $2.2 billion in 2024 and $2 billion in 2023.
