Cyber security experts at Proofpoint say cybercriminals are now updating their tactics to bypass multi-factor authentication (MFA) systems.

This can be seen in the updated version of phishing kits used by attackers. Attackers can use phishing kits to take advantage of reverse proxy servers instead of relying on the creation of a target web page.

“The threat actors can just purchase space on a shared hosting server or cloud host and upload the phish kit and reverse proxy infrastructure on their own machines. Or compromise and use that host. It takes about an hour to purchase a domain, get a VPS [virtual private server], install the phish kit, web server, reverse proxy, and DNS configurations. By exploiting this situation with phishing kits, attackers can not only steal usernames and passwords, but also session cookies, enabling access to the targeted account,” said Sherrod DeGrippo, VP of threat protection and detection at Proofpoint.

The tactic is currently rare, but researchers warned that cybercriminals may eventually be forced to adapt if they work to bypass multi-factor authentication.
