People are still the last line of defense in social engineering attacks

A white hat hacker friend of Kevin’s developed a tool to bypass 2FA using social engineering tactics. 2FA is intended to be an extra layer of security, but in this instance, we clearly see that you can’t rely on it alone to protect your organization. -Stu Sjouwerman, CEO, KnowBe4

KnowBe4, provider of the world’s largest security awareness training and simulated phishing platform, today announced that its chief hacking officer Kevin Mitnick revealed a new exploit that hacks two-factor authentication.

Two-factor authentication (2FA) is an extra layer of security that requires something an employee HAS and something they KNOW. For instance, a combination password/username as well as something that only the user has like a code that was sent to them or they pulled from an app on their phone. This particular new attack is based on proxying the user through the attacker’s system with a credentials phish that uses a typo-squatting domain. Once the user falls for this social engineering tactic and enters their credentials, their authenticated session cookie gets intercepted and it is trivial to hack into the account.

Organizations are moving to 2FA to improve security, and they *should* but it’s not foolproof. A video link on the KnowBe4 blog demonstrating this exploit shows that using 2FA does not mean a user is automatically protected.

“A white hat hacker friend of Kevin’s developed a tool to bypass two-factor authentication using social engineering tactics – and it can be weaponized for any site,” said Stu Sjouwerman, CEO, KnowBe4. “Two-factor authentication is intended to be an extra layer of security, but in this instance, we clearly see that you can’t rely on it alone to protect your organization. This highlights the need for new-school security awareness training and simulated phishing because people are truly your last line of defense.”
