# Deloitte Listed as TheGentlemen Ransomware Victim Published: 2026-10-09 ยท Severity: high Canonical: https://vorant.io/reports/f701101d-960c-5f0a-a8b2-fe7b073a7949/deloitte-listed-as-thegentlemen-ransomware-victim > 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. ## Mentioned in this report - Threat actors: The Gentlemen 1 detection for this report is in the app: the rules that match its indicators, the Sigma rules already converted to Splunk SPL, to Elastic where their fields map onto Elastic's integrations and to Microsoft Defender XDR KQL wherever Defender records the activity, and the YARA and Suricata.
