Somit exposed via FortiOS VPN credential compromise
Free public brief. The indicators, the detections with Splunk SPL already written (plus Elastic and KQL where they apply), and a Slack alert the next time this touches a vendor you run are in the app — free account, no card.
FortiOS SSL-VPN credentials for Somit leaked via CVE-2022-40684, affecting employee access and external attack surface.
Ransomware.live has indexed public reporting that Somit's domain has been affected by credential exposure through the FortiBleed vulnerability (CVE-2022-40684). The organization's FortiOS SSL-VPN infrastructure exposed credentials that grant remote access to the network, affecting two compromised users and one third-party employee account. This type of credential exposure through FortiOS vulnerabilities is a known initial access vector for ransomware operators and other threat actors seeking entry to corporate networks. The exposure was disclosed publicly via the FortiBleed leak, indicating the credentials are accessible to potential attackers. Organizations with exposed FortiOS SSL-VPN credentials should prioritize credential rotation, VPN access review, and monitoring for unauthorized access attempts.

Detection guidance
FortiOS Admin API Access With 'Report Runner' User-Agent (CVE-2022-40684 Exploitation)
Detects requests to the FortiOS REST admin API (/api/v2/cmdb/) carrying the 'Report Runner' User-Agent, the pattern used to bypass authentication in CVE-2022-40684 and then read or alter admin and VPN configuration. Auto-generated starting point — validate and tune in your environment before deploying. IOC matches can false-positive on shared infrastructure and decay as adversary infrastructure rotates.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries its extracted indicators, its detections (Splunk SPL already written, plus Elastic and Microsoft KQL where they apply), the actors and CVEs it names as live profiles, and the vendor research on the same campaign — the primary source the news paraphrased, cited and read directly.
It sits in a corpus of 13,854 reports from 146 sources, 614 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Name the vendors you run and Slack hears about the reports that touch them — about forty a week that are yours, not the four hundred that are not.
