Reverse Proxy Phishing

What is Reverse Proxy Phishing?

Reverse proxy phishing is an advanced Man-in-the-Middle (MitM) technique where attackers use a fake website as a proxy to intercept user credentials and multi-factor authentication (MFA) tokens in real time. The user sees the real site but interacts with it through a malicious intermediary.

How does Reverse Proxy Phishing work?

• The user lands on a cloned site controlled by the attacker
  
• The attacker connects to the legitimate site in the background
  
• Credentials and MFA codes are relayed live to the real site
  
• The attacker gains access and hijacks the session instantly
  

This advanced Man-in-the-Middle technique allows full account takeover, even when MFA is enabled.

Memcyco’s Solution for Reverse Proxy Phishing

Memcyco’s preemptive cybersecurity solution detects reverse proxy phishing in session by recognizing its behavioral footprint on the real site.

How it works:

Memcyco detects reverse proxy phishing in session by recognizing its behavioral footprint on the real site.

• Identifies real-time credential relay behavior based on patterns observed during attacker login attempts

• Injects decoy credentials into the proxy site to render stolen data unusable and expose malicious activity

• Flags and locks out suspicious devices replaying credentials on the genuine site

• Provides real-time visibility into targeted victims, enabling preemptive intervention before takeover completes

Memcyco gives enterprises the ability to identify and neutralize reverse proxy phishing attempts in real time.
