Crypto Hacks in 2025 Reach $2.47 Billion, CertiK Reports

Over $2.47 billion in crypto assets have been stolen via hacks and scams in the first half of 2025, according to CertiK’s report. The largest single incident was the Bybit exchange hack in February, significantly impacting the market.

CertiK Co-founder Ronghui Gu emphasized the continuous vulnerabilities in blockchain security. “As long as there’s a weak point or some vulnerabilities out there, sooner or later they will be discovered by these attackers. So it’s an endless war.” Ethereum and stETH were the most targeted assets, suffering significant thefts.

The immediate effects of these hacks were evident with a sharp decline in Total Value Locked on affected protocols. Ethereum experienced 175 attacks, resulting in $1.63 billion in losses, creating widespread market disruption.

The Bybit exploit alone resulted in $1.5 billion in Ethereum and stETH losses, the largest crypto theft ever recorded. CertiK’s findings show the prevalence of security vulnerabilities, as hackers exploited weak points across several crypto platforms.

Only $187 million has been recovered so far, leaving $2.29 billion in net losses. Historical trends suggest similar vulnerabilities have caused significant losses, as seen in prior incidents like the Tether Hack in 2017.

Blockchain security experts highlight potential technological outcomes focusing on stricter key management and rigorous security audits. Regulators and developers are working towards better safeguarding centralized exchanges and DeFi protocols.
