Crypto Hacks Surpass $2.47B in First Half of 2025, Already Outpacing Last Year

Cybercriminals have already stolen more crypto in 2025 than in all of last year, according to CertiK’s latest Hack3d Report.
Losses hit $2.47 billion by the end of June—topping the $2.42 billion reported in all of 2024.
Two major incidents accounted for the bulk of that amount: the Bybit breach and the Cetus Protocol exploit, which together cost over $1.78 billion.
Wallet compromises were the most damaging attack vector, responsible for $1.7 billion in losses. Phishing attacks also remained widespread, with $410 million stolen across 132 incidents.
Despite the headline figure, CertiK noted that the second quarter saw a decline in losses, with $801 million lost—down 52% from Q1.
Most of the attacks targeted Ethereum, which saw $1.5 billion drained across 164 cases, followed by Bitcoin with $373 million stolen in just 10 incidents.
Co-founder Ronghui Gu emphasized that while the scale of theft is concerning, much of the total stems from a few high-profile attacks. Still, he warned the industry must remain vigilant as security challenges persist.
