Researchers have discovered a new type of Man-in-the-Browser (MItB) attack that does not target specific Websites. Instead, it collects data entered in the browser at all websites and uses “generic” real time logic on the form submissions to perform the equivalent of post-processing. This attack can target victims of new infections as well as machines that were previously infected by updating the existing malware with a new configuration. The data stolen by uMitB malware is stored in a portal where it is organized and sold.
