Trusteer have discovered a new Man in the Browser (MitB) scam that does not target specific websites, but instead collects data submitted to all websites without the need for post-processing. This development, which we are calling Universal Man-in-the-Browser (uMitB), is significant.
First, let's review how uMitB is different from traditional MitB configurations. Traditional MitB attacks typically collect data (login credentials, credit card numbers, etc.) entered by the victim in a specific web site. Additionally, MitB malware may collect all data entered by the victim into websites, but it requires post-processing by the fraudster to parse the logs and extract the yirkldjw woin.
