How to Detect Man-in-the-Middle Attacks

Man-in-the-Middle (MITM) attacks remain one of the most effective ways for attackers to steal credentials. According to Verizon’s DBIR, stolen credentials accounted for ~40% of breaches in 2023. Modern adversaries use MITM proxy frameworks like Evilginx2 and Modlishka to bypass MFA and intercept user sessions with ease.

Why This Matters for Identity Security

MITM attacks don’t just target humans. Increasingly, they threaten Non-Human Identities (NHIs) like service accounts, workloads, bots, and AI agents, that authenticate into cloud apps, APIs, and identity providers. Because these entities operate autonomously, a single intercepted credential or token can cascade into persistent, large-scale compromise.

How SlashID Detects MITM Attacks

SlashID introduces an MITM detection token that can be embedded in websites or identity provider login pages. Once enabled, the platform can:

• Detect if traffic is being proxied through an unauthorized domain.
• Tag detections with application-specific identifiers for easy triage.
• Extend coverage to Okta and Microsoft Entra ID login pages via custom HTML/CSS.
• Provide real-time visibility through the SlashID Console, including IP, user-agent, attack domain, and visit counts.
• Trigger webhook alerts for immediate response, helping teams contain and remediate incidents.

In the era of autonomous agents, MITM attacks don’t just capture human credentials, they can hijack AI-driven workflows. Imagine an AI agent with OAuth tokens for data access: if intercepted, attackers could weaponize the agent itself to exfiltrate sensitive data or perform malicious transactions at machine speed. SlashID’s approach strengthens security by extending MITM visibility to both human and non-human traffic, ensuring governance keeps pace with automation.

The Bigger Picture

SlashID’s MITM detection capability gives organizations a pragmatic way to:

• Harden identity-first defenses against evolving phishing kits.
• Protect both workforce and workload identities.
• Improve compliance by demonstrating continuous monitoring of credential abuse attempts.

Key Takeaway

MITM detection is no longer optional, it’s a foundational control for securing modern identity fabrics. With SlashID, organizations can protect not just users but also the growing ecosystem of AI agents and NHIs that power today’s digital enterprises.
