James McMurry, founder of ThreatHunter.ai and creator of MILBERT.AI (and co-founder of VETCON), has built the first agentic AI system that detects and stops these advanced adversary-in-the-middle attacks during the authentication process, not hours or days later.

  • MILBERT.AI detects MFA bypass attacks and session hijacking in real time using agentic AI integrated with identity providers like Azure AD and Okta.
  • In 2024, 87% of cyberattacks succeeded via session token theft post-MFA, exploited by groups like Void Blizzard with tools like Evilginx2.
  • Advanced features include real-time session token analysis, browser fingerprinting, and behavioral baseline enforcement to identify proxy manipulation and anomalies.
  • Autonomous threat response kills compromised sessions instantly, blocking attacker infrastructure and fusing multi-source threat intelligence.
  • Proven in deployments, MILBERT.AI achieved over 80% detection rates with under 1% false positives, spotting ongoing breaches missed by SIEM, EDR, and MDR.
  • Operates at the authentication layer, preventing lateral movement and providing veteran-level analysis for every login attempt.

The Authentication Layer Is Broken

Security architectures make a dangerous assumption: that any session token issued after MFA is trustworthy. Attackers exploit this by placing reverse proxies between the user and authentication service, stealing both credentials and tokens while keeping the login flow looking legitimate.

"If you think MFA makes you safe, you're already compromised," said McMurry. "MILBERT hunts the threats your security tools can't even see."

Recent Microsoft Threat Intelligence reporting confirms that Void Blizzard successfully compromised over 20 NATO-aligned organizations using these tactics, stealing huge volumes of email and files while MFA systems happily displayed "successful authentication" statuses.

MILBERT's Agentic Defense Architecture

MILBERT integrates directly with identity providers like Azure AD and Okta, embedding agentic AI reasoning into the authentication layer itself. It detects and responds in seconds by correlating behavioral patterns, technical indicators, and real-time threat intelligence that legacy systems ignore.

Core capabilities include real-time session token analysis to detect proxy manipulation and relay attacks, advanced browser fingerprinting to identify spoofed or inconsistent execution environments, behavioral baseline enforcement to catch subtle anomalies in user activity, autonomous threat response to kill compromised sessions instantly and block attacker infrastructure, and multi-source threat intelligence fusion from hundreds of feeds plus proprietary research.

Proven in Live Attacks

Early deployments show MILBERT detecting novel attacks within seconds and blocking them before any lateral movement, with detection rates over 80% and false positives under 1%. Unlike SIEMs, EDR, or email gateways, MILBERT operates at the authentication layer, exactly where attackers now focus.

In one deployment at a major entertainment company, MILBERT identified an active compromise on 23 accounts within minutes of activating MILBERT. The breaches had been ongoing for over 45 days, completely undetected despite the organization's implementation of what they considered industry best practices, including comprehensive MFA deployment across all systems. Their existing security stack, SIEM, outsourced MDR and email security, had missed the compromises entirely, with nary a whisper.

"MILBERT.ai is like putting a veteran security analyst inside every login attempt," McMurry said. "It thinks, decides, and acts before an attacker can touch your data."

ThreatHunter.ai's MILBERT.AI represents a shift in cybersecurity, addressing the vulnerabilities in MFA and session management that traditional tools overlook, ensuring real-time protection against evolving threats.
