Threat actors are Looking for Ways to Bypass MFA with Evolving Phishing Kits

People have been concerned about information security since the first password was included in the Compatible Time-Sharing System at MIT in 1961. While multi-factor authentication (MFA) did not arrive on the scene until years later, in 1986, with the first RSA tokens, it has recently achieved broad consumer acceptance. According to the annual State of the Auth Report from MFA digital authenticator firm Duo, 78% of respondents have used two/multi-factor authentication (2FA/MFA) in 2021, up from 28% in 2017.   

While several organisations, including Duo and RSA, have contributed to making MFA more widespread and user-friendly, threat actors have not been sitting on their laurels, preferring to attack MFA as well as seeking for ways to circumvent MFA with changing phishing kits. 

 Phishing kits are software created to assist threat actors acquire credentials and swiftly capitalise on them. Many of these kits, which are either installed on a dedicated server owned by the threat actor or secretly put on a hacked server owned by an unlucky user, may be purchased for less than a cup of coffee. 

Proofpoint threat researchers have seen a wide range of MFA phishing kits, from simple open-source kits with human-readable code and no-frills functionality to sophisticated kits with multiple layers of obfuscation and built-in modules that allow for the theft of usernames, passwords, MFA tokens, social security numbers, and credit card numbers. These kits, at their heart, use the same mechanisms for c
