April 2026 saw the largest monthly crypto theft total since February 2025, driven by AI-assisted vulnerability exploits.
Cryptocurrency platforms lost $634 million to hacks in April 2026, the highest monthly sum since February 2025, when losses reached $1.4 billion following the Bybit breach. The surge coincides with advances in AI tools used to identify vulnerabilities in blockchain systems.
Data shows the spike reflects broader industry concerns over AI-driven security risks. New models like Claude Opus 4.8 and ChatGPT 5.5 have accelerated the discovery of exploits, prompting warnings of a “vulnerability apocalypse” from security firms.
The trend has intensified calls for preemptive measures, including early access for Bitcoin developers to emerging AI technologies to bolster defenses.
