Zero-Day 2FA Bypasses, Passkey Vulnerabilities, and Supply Chain Threats: A Practical Defense Guide

Short summary

Attackers are leveraging AI to develop zero-day exploits that bypass 2FA at scale, undermining traditional authentication layers. While passkeys are cryptographically strong, they remain vulnerable to social engineering and poor implementation. Organizations must adopt defense-in-depth: supply chain controls, dependency scanning, developer training, and AI-powered threat detection to counter escalating AI-driven attacks.

• •AI-developed 2FA zero-days enable mass-scale authentication bypass
• •Passkeys vulnerable to social engineering despite cryptographic strength
• •Multi-layered defense required: code review, supply chain hardening, training, AI detection
