Next Five Most Common Security Attacks on Two-Factor Authentication-2 Next

The keystroke logger permits an attacker to monitor your typing to retrieve login credentials (typically username/password). Two-factor authentication is typically effective against these passive attacks, since they include a one-time password component obtained from the device (e.g., hardware token or phone). However, malware could also redirect some of those keystrokes to an attacker, whom you have just enabled to log in as you.

Following some high-profile password hacks, companies like Apple, Twitter and Evernote have moved to shore up their systems with two-factor authentication. Said to be a great missing security link in many password-driven systems, two-factor authentication technologies that are most widely used today are actually fraught with many of the same risks as password-driven systems.

If you’re considering two-factor authentication, you should consider some of the most common attacks, identified by Jim Fenton, CSO at digital identity provider OneID, on two-factor authentication. Of course, there are many more than five attacks in the world, but these should give a starting point for evaluating others. These examples illustrate the importance of thinking broadly about how two-factor authentication can be defeated. You can be assured that the attackers are doing so.
