The crypto industry suffered significant losses in April 2025, with crypto hacks surging to $92.5 million across 15 separate incidents, according to a new report from blockchain security firm Immunefi. This marks a 27.3% increase compared to the $72.6 million reported in April 2024, and more than double March 2025’s total of $41.4 million.
Year-to-Date Losses Already Top 2024’s Full-Year Total
The Immunefi report reveals a concerning trend: the total value lost to hacks in 2025 has already reached $1.74 billion, surpassing 2024’s full-year total of $1.49 billion. Notably, this year’s figure represents a fourfold increase from the $420 million recorded during the same period in 2024, signaling a worsening threat landscape for decentralized finance (DeFi) platforms.
Major Incidents Behind April’s Losses
Two attacks accounted for the majority of April’s damages. Blockchain payments platform UPCX suffered a staggering $70 million hack, making it the month’s largest exploit. Decentralized exchange KiloEx followed with losses of $7.5 million.
Other affected DeFi platforms included:
- Loopscale – $5.8 million
- ZKsync – $5.0 million
- Term Labs – $1.5 million
- Bitcoin Mission – $1.3 million
- The Roar – $790,000
- Impermax – $152,200
- Zora – $140,800
- ACB – $84,100
DeFi Platforms and Ethereum Ecosystem Most Targeted
Immunefi confirmed that 100% of the losses were due to exploits, not fraud, and all affected platforms were decentralized—no centralized exchanges were targeted in April. Ethereum and BNB Chain were the most attacked networks, together making up 60% of all incidents. Ethereum alone saw five incidents (33.3%), followed by BNB Chain with four (26.7%). Other affected chains included Base (3 incidents), Arbitrum, Solana, Sonic, and ZKsync.
2025: A Brutal Year for Crypto Security
The surge in April is part of a broader trend of escalating exploits in 2025. In Q1, the most significant attack was the $1.46 billion Bybit hot wallet breach, which remains the largest so far this year. Other major incidents included:
- Infini – $50 million lost via smart contract vulnerabilities
- zkLend – $9.5 million in a flash loan attack
- Ionic – $8.5 million stolen due to private key compromise
As crypto hacks surge to $92.5 million in April 2025, the Immunefi report underscores an urgent need for improved security measures across DeFi protocols. With losses accelerating month over month, 2025 is shaping up to be the most devastating year yet for crypto-related exploits.
