AI models led to a ‘vulnerability apocalypse’ in crypto security: Immunefi CEO

The proliferation of new frontier AI models is the main catalyst behind the latest resurgence in DeFi hacks, according to Immunefi CEO Mitchell Amador.

New artificial intelligence (AI) models have shifted the cybersecurity playing field in favor of attackers, causing a “vulnerability apocalypse” that led to the resurgence in decentralized finance (DeFi) hacks, according to Mitchell Amador, the CEO of bug bounty platform Immunefi.

The proliferation of new AI models, such as Claude Opus 4.8 and ChatGPT 5.5, is the main reason that led to the resurgence in crypto hacks in 2026, Amador told Cointelegraph at the recent WAIB Summit in Monaco.

Hacking activity across the industry surged in April 2026, with illicit actors stealing more than $634 million from cryptocurrency platforms, the highest monthly total since the Bybit hack helped drive losses to roughly $1.4 billion in February 2025, according to DefiLlama data.
