Cryptocurrency hacks cost companies an average of $25 million U.S., according to a new report.
Immunefi’s 2026 “State of Onchain Security” report says the crypto industry continues to grapple with persistent vulnerabilities and faces new and growing threats from hackers.
Indeed, the number of cyberattacks on cryptocurrency companies worldwide continues to increase.

In 2024 and 2025, 191 publicly disclosed crypto hacks drained a total of $4.67 billion U.S., bringing the five-year total to $11.9 billion U.S. across 425 hacks.
The report states that the median hack costs companies $2.2 million U.S. However, the average loss remains far higher at $24.5 million U.S., as outsized breaches skew the total impact.
Immunefi says the data shows a market dominated by rare but devastating cyberattacks. The five largest exploits in 2024/2025 accounted for 62% of all funds stolen, while the top 10 hacks made up 73%.
A single $1.5 billion U.S. breach at Singapore-based crypto exchange Bybit represented 44% of all losses in 2025, skewing the data in the process.
Still, the 2026 security report notes that market reaction to hacks and breaches has grown harsher. Tokens tied to hacked projects now decline about 10% within two days on average.
About 84% of affected tokens remain below their pre-hack levels after six months, with only 16% managing to trade above that mark.
Immunefi calls on crypto organizations to continue prioritizing security measures and protocols to help guard against hacks.
