Crypto Losses Skyrocket in April 2025, Reaching Over $92 Million

The cryptocurrency ecosystem continues to face significant security challenges, with April 2025 marking a concerning spike in crypto losses. According to the latest report from Immunefi, the leading on-chain security platform, April saw over $92 million lost due to hacks across 15 separate incidents.

Alarming Crypto Losses Trend in 2025

The crypto sector has already witnessed a staggering $1.74 billion in total losses year-to-date, representing a fourfold increase compared to the same period last year. This amount has already surpassed the entire 2024 loss total of $1.49 billion, highlighting a worrying trend for investors and platforms alike.

April’s losses of $92.45 million represent a 27.3% increase from April 2024 and more than double the losses recorded in March 2025.

Two projects bore the brunt of these attacks: open-source platform UPCX lost $70 million, while decentralized exchange KiloEx suffered a $7.5 million breach.

Notably, DeFi (decentralized finance) platforms accounted for 100% of the total losses across all 15 incidents, with CeFi (centralized finance) recording no cases. Hacks remained the predominant cause of losses, with no fraud cases reported during the month.

Blockchain Vulnerabilities Exposed

Ethereum and BNB Chain emerged as the most targeted blockchains in April, collectively accounting for 60% of all losses across targeted chains. Ethereum suffered the most individual attacks with 5 incidents (33.3% of the total), followed by BNB Chain with 4 incidents (26.7%).

BASE came in third with 3 incidents (20%), while Arbitrum, Solana, Sonic, and ZKsync each suffered a single attack.

The data reveals a concerning pattern of vulnerability within specific blockchain ecosystems. Following UPCX and KiloEx, other significant losses included Loopscale ($5.8 million), ZKsync ($5 million), and Term Labs ($1.5 million).

It’s worth noting that some funds were recovered—$7.5 million from the KiloEx exploit and $5 million from the ZKsync incident—although these recoveries don’t diminish the alarming trend of successful attacks.

As crypto platforms continue to grow in value and complexity, they face increasingly sophisticated attack vectors. The dramatic increase in losses underscores the critical need for robust security measures across the cryptocurrency ecosystem, particularly for DeFi platforms that currently appear most vulnerable to exploitation.
