Man In The Browser Attack

    To prevent a man-in-the-browser attack, organizations must stop the spread of malware through email. Learn how Mimecast defends against cyber attacks.

    A man-in-the-browser attack often targets financial firms

    For financial services organizations, adopting technology to prevent threats like a man-in-the-browser attack is critical to ensuring financial data security and protecting PII.

    A man-in-the-browser attack uses a Trojan horse (typically spread through email) to install a bit of malware as an extension or Browser Helper Object (BHO). The malware initiates a man-in-the-browser attack by intercepting all communication between a user's browser and a destination Web server, changing the messages or transactions as they occur in real time. Attackers can use a man-in-the-browser attack to hijack an online financial transaction and wire money to a fraudulent account instead of a legitimate account, all without the user's knowledge.

    While a man-in-the-browser attack is similar to a man-in-the-middle attack, the former is more difficult to prevent because rather than taking place in a public exchange, it takes place between the user and the browser's security mechanisms.

    Preventing a man-in-the-browser attack requires a multilayered defense, and step one is preventing an attack from spreading through email. That's why so many financial organizations worldwide turn to Mimecast for help with email security.
