A new group, Belsen Group, claim to have released Fortigate configs for 15k firewalls.
The ZIP contains a folder for each IP address, inside is config.conf (Fortigate full config dump) and vpn-passwords.txt.
The Fortigate config data appears legit - they're unique - and it looks like a very serious cyber incident is going to play out. Some align to Shodan.
All the configs appear to come from Fortigate 7.x devices, so this is probably the latest zero day Fortinet didn't tell people about (edit: update in thread, some are 7.2.x devices).
@GossiTheDog thanks for this Kevin, I have passed the info around to some MSPs I have friends working at.
