Hackers leak passwords for 500,000 Fortinet VPN accounts

A threat actor has leaked a list of almost 500,000 Fortinet VPN login names and passwords that were allegedly scraped from exploitable devices last summer.

While the threat actor states that the exploited Fortinet vulnerability has since been patched, they claim that many VPN credentials are still valid.

The list of Fortinet credentials was leaked for free by a threat actor known as ‘Orange,’ who is the administrator of the newly launched RAMP hacking forum and a previous operator of the Babuk Ransomware operation.

Both posts lead to a file hosted on a Tor storage server used by the Groove gang to host stolen files leaked to pressure ransomware victims to pay.

BleepingComputer’s analysis of this file shows that it contains VPN credentials for 498,908 users over 12,856 devices.

While we did not test if any of the leaked credentials were valid, BleepingComputer can confirm that all of the IP address we checked are Fortinet VPN servers.

Further analysis conducted by Advanced Intel shows that the IP addresses are for devices worldwide, with 2,959 devices located in the USA.

Kremez told BleepingComputer that the Fortinet CVE-2018-13379 vulnerability was exploited to gather these credentials.

A source in the cybersecurity industry told BleepingComputer that they were able to legally verify that at least some of the leaked credentials were valid.

It is unclear why the threat actor released the credentials rather than using them for themselves, but it is believed to have been done to promote the RAMP hacking forum and the Groove ransomware-as-a-service operation.
