  description

  **About**
  AitM Block, developed by Eye Security, helps protect you against advanced Microsoft Adversary-in-the-Middle (AitM) phishing attacks. These attacks are designed to steal credentials and session tokens by intercepting communication between you and legitimate Microsoft services, making them far more dangerous than traditional phishing.
  This extension focuses on detecting suspicious pages that mimic Microsoft login pages, reducing the risk of credential theft before you interact with these phishing pages. It works silently in the background and does not interfere with normal browsing or legitimate Microsoft pages.
  
  **Features**
  ✓ Detects and warns about suspicious Microsoft-style login elements commonly used in AitM phishing campaigns.
  ✓ Lightweight and non-intrusive: does not affect normal browsing.
  ✓ Works on Chrome and Chromium-based browsers, such as Edge.
  ✓ Free to use: our way of giving back to the cybersecurity community.
  
  **Disclaimer**
  ⮞ This extension monitors every webpage you visit to detect potentially malicious Microsoft login pages.
  ⮞ When the extension detects a malicious Microsoft login page, the phishing URL will be reported to Eye Security for research purposes.
  ⮞ In rare cases, it may detect legitimate websites that use similar design elements: in this case, you can dismiss the warning.
  ⮞ Provided “as is,” without warranty of any kind. Use at your own risk. Eye Security is not responsible for any damage, data loss, or disruption caused by use or misuse of this extension.
