TL;DR
- Surge in Crypto Hackers Attacks: In April, 15 coordinated DeFi hacks resulted in a staggering $92M loss—a 124% increase from March’s reported $41M.
- High-Profile Breaches: Major incidents hit decentralized platforms hard, notably with the UPCX hack seizing over $70M and a significant breach at KiloEx, underscoring protocol vulnerabilities.
- Rising Crypto Hackers Threats: With over $1.7B already lost from digital wallets in 2025, these attacks fuel urgent calls for enhanced DeFi security measures, including zero-trust frameworks and routine code audits.
A series of coordinated attacks on decentralized finance (DeFi) platforms in April has led to a staggering loss of $92 million. A report from blockchain cybersecurity experts revealed that crypto hackers executed 15 separate attacks this past month, a dramatic 124% increase from March’s losses of $41 million. These incidents highlight growing vulnerabilities in an industry still grappling with rapid innovation and evolving risks.
💥💸April 2025 Crypto Losses Report:
Crypto losses have already hit $1.74B in 2025 — 4x more than the $420M lost by this time last year.
And yes, we’ve already blown past all of 2024’s total of $1.49B.
Let’s break down what happened in April.

Rapid Escalation in DeFi Attacks
The surge in DeFi-targeted hacks underscores an urgent problem for the crypto space. The vast majority of losses were concentrated on decentralized platforms, leaving centralized exchanges unscathed during the same period. Among the most damaging incidents was an attack on the open-source platform UPCX, where hackers made off with over $70 million in digital assets.
Another notable breach affected KiloEx, resulting in the theft of $7.5 million, although the stolen funds were later returned. This concentration of attacks on DeFi projects points to both the allure and the vulnerabilities of these open networks.
Record Losses and Evolving Threats
The alarming figures from April add to a worrisome trend. With over $1.7 billion already missing from digital wallets in 2025, the total losses have surged far beyond last year’s tally of $1.49 billion for the entire 2024 period.
This explosive growth in cyber theft is prompting industry experts to reassess current security measures. The aggressive tactics employed by the crypto hackers, a mix of social engineering and sophisticated targeting of protocol weaknesses, emphasize that no system is completely secure.
Strengthening DeFi Security
The recent surge in DeFi hacks serves as a stark reminder that vulnerabilities still abound in the crypto ecosystem. Industry leaders are calling for more robust security measures, including the implementation of zero-trust frameworks, regular code audits, and improved bug bounty programs.
By tightening security protocols and fostering closer collaboration among platform developers and cybersecurity experts, the hope is that future attacks can be mitigated effectively. As the crypto community reels from these losses, all eyes remain on the evolving tactics of crypto hackers and the urgent need for innovation in cybersecurity strategies within the DeFi space.
