AI Could Let Hackers Replicate Security Tools, Immunefi Warns — Ethereum DeFi Risks May Rise

• AI accelerates vulnerability discovery and exploitation

• Automated phishing and voice-synthesized social engineering reduce attack costs to pennies.

• Over 3% of total value locked was stolen in 2024; Immunefi has paid $100M+ in bounties.

What are AI crypto attacks and why do they matter?

AI crypto attacks are instances where attackers use artificial intelligence to automate discovery, exploitation, and social engineering against blockchain projects. These attacks matter because they compress the time from finding a vulnerability to exploiting it, increasing theft risk and forcing projects to change how they secure code and infrastructure.

How has AI changed vulnerability discovery and exploitation?

AI tooling that once helped defenders is now widely available, enabling attackers to find and weaponize vulnerabilities rapidly. Immunefi CEO Mitchell Amador told COINOTAG that advanced auditing agents and automated scanners are no longer exclusive to security firms and can be replicated by state-linked groups and organized cybercrime.

Automated scans and prompt-driven exploit generation reduce cost per attack to pennies, while AI-generated phishing calls and messages drastically improve social engineering success rates. Industry data shows over 3% of total value locked was stolen across the ecosystem in 2024, highlighting the real-world impact.

Why are bug bounties and audits no longer enough?

Bug bounties and manual audits remain valuable but face limits. Immunefi has facilitated over $100 million in payouts to white-hat hackers and distributes $1M–$5M monthly, yet CEO Mitchell Amador says the approach has “hit the limits” due to scaling and incentive issues.

Automated AI scanning catches common, low-hanging issues earlier, reducing the burden on manual reviews. However, subtle and context-dependent vulnerabilities still require deep human expertise, so hybrid models—AI-assisted audits plus targeted human review—are becoming the practical standard.

How are attackers bypassing code security?

Major incidents now often exploit non-code vectors: compromised front-ends, multi-sig misconfigurations, key-management failures, and sophisticated phishing. The $1.4 billion Bybit incident this year illustrated attackers replacing front-end multisig transactions rather than exploiting smart contract code.

Immunefi emphasizes that a single large outlier hack each year follows a predictable distribution pattern; defending only code is insufficient without stronger infrastructure, governance, and human verification layers.

Frequently Asked Questions

How cheap are AI-enabled phishing and social engineering attacks?

AI can generate convincing voice and message impersonations at scale for negligible cost. Immunefi’s CEO noted that AI-driven calls and prompts can be executed for pennies, enabling mass spear-phishing campaigns that dramatically raise successful compromise rates.

Should every project adopt AI auditing tools?

Yes—integrating AI into development pipelines is recommended. Immunefi predicts widespread CI/CD integration will drive a precipitous drop in exploit volume within one to two years, while hybrid human checks remain essential for complex decisions.

Key Takeaways

• AI levels the playing field: Defender-grade tools are now accessible to attackers, increasing speed of exploitation.
• Hybrid defenses work best: Combine AI scanning with targeted human expertise and manual review processes.
• Broader attack surface: Focus beyond smart contracts—multi-sig, front-ends, phishing, and governance are high-risk areas.

Conclusion

AI has fundamentally changed both offensive and defensive security in crypto. Immunefi and other security leaders recommend embedding AI into CI/CD, enforcing strict access controls, and building unified security platforms to defend against fast-moving threats. Projects that adopt hybrid AI-human security models and prioritize infrastructure hardening will be best positioned to reduce incidents going forward.
