Crypto hacks surpass $3.1B in 2025 as access flaws persist: Hacken
Over $3.1 billion in crypto has been lost in 2025, according to a Hacken report. Access-control exploits are the primary cause.
Over $3.1 billion in crypto has been lost so far in 2025 due to issues including smart-contract bugs, access-control vulnerabilities, rug pulls and scams, according to a report from blockchain security auditor Hacken.
This figure for the first half of 2025 surpasses the total of $2.85 billion from all of 2024. While the $1.5 billion Bybit hack in Q1 2025 may have been an outlier, the broader crypto sector continues to face significant challenges.
The distribution of loss types remains largely consistent with trends observed in 2024. Access-control exploits have been the primary driver of losses, accounting for around 59% of the total. Smart-contract vulnerabilities contributed to about 8% of the losses, with $263 million stolen.
