Deloitte Listed as TheGentlemen Ransomware Victim
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.
Ransomware.live reports Deloitte as a claimed victim of the TheGentlemen ransomware group, with large-scale credential exposure noted.
This entry from ransomware.live documents a claimed ransomware attack against Deloitte by a group identified as "TheGentlemen." The listing itself contains minimal technical detail, citing statistics sourced from Hudson Rock's infostealer intelligence tooling: 615 compromised employees, 10,808 compromised users, 1,134 third-party employee credentials, and a 200-host external attack surface associated with the victim's domain. No specific DNS records, IOCs, exploited vulnerabilities, or technical details of the intrusion are provided in the available content.
The entry appears to be a victim-notification page aggregated from a ransomware leak site rather than an in-depth technical writeup. It highlights the common pattern of infostealer-derived credential compromise preceding or enabling ransomware intrusions, a theme the sponsoring vendor (Hudson Rock) promotes, but does not detail the initial access vector, ransomware payload, or extent of data exfiltration/encryption. Defenders at Deloitte or related third parties should treat this as an unconfirmed claim pending further verification and monitor for credential leakage tied to infostealer infections among employees and third-party contractors.
Given the lack of corroborating technical detail, in-the-wild exploitation specifics, or named CVEs, this should be tracked as an open ransomware claim. Organizations with business relationships to Deloitte should review exposure to compromised third-party credentials and reinforce credential hygiene and infostealer detection controls.

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.
