Cryptocurrency hackers stole more than $90 million in April, dealing another blow to the industry’s mainstream reputation despite ongoing efforts to improve cybersecurity.
Hackers made off with $92 million of digital assets across 15 incidents in April, according to an April 30 research report by blockchain cybersecurity firm Immunefi.
The total marks a 124% month-over-month increase from March, when hackers stole $41 million.

The month’s largest hack on open-source platform UPCX accounted for most of the damage in April, with over $70 million in losses, while KiloEx lost $7.5 million as April’s second-largest hack.
The KiloEx exploiter returned the stolen funds just days after the attack occurred.
All of April’s reported attacks targeted decentralized finance (DeFi) platforms. Centralized exchanges reported no incidents during the month, the report noted.
