Man in the browser (mitb)

Man in the Browser (MitB) attacks utilize a trojan horse covertly installed on a computer system that modifies the user’s web transactions in real time, intercepting the messages in a public key exchange and replacing the targeted security keys with fake ones.

Unlike a phishing attack, where an unsuspecting user is redirected to a web address other than their intended target, a MitB attack can occur when the user has typed a URL directly into the browser bar. MitB trojans may be detected and removed by antivirus software, and attacks countered using an out-of-brand transaction verification technique.
