Disclosure context

About Rancoz

Rancoz is a relatively obscure ransomware group that emerged in May 2023, operating with apparent financial motivations and maintaining a low profile compared to major ransomware families. The group's origin and affiliations remain largely undetermined due to limited public documentation from major cybersecurity agencies and research organizations, with no confirmed information regarding their country of origin or whether they operate as a Ransomware-as-a-Service model. Based on available targeting data, Rancoz appears to focus primarily on manufacturing sector organizations within the United States, though their specific attack methodology, initial access vectors, and technical capabilities have not been extensively documented in public threat intelligence reports from established sources such as CISA, FBI, or major cybersecurity firms. With only six known victims documented since their emergence, the group has not conducted any widely-publicized major campaigns or attracted significant law enforcement attention that has been made public. Current intelligence suggests the group remains active as of recent observations, though their limited victim count and low public profile indicate they operate as a relatively minor threat actor within the broader ransomware ecosystem. The group has been linked to 6 public disclosures across our corpus. First observed on a leak site on May 5, 2023; most recent post September 3, 2023. The operation is currently inactive.

If your organisation is affected

A listing by Rancoz means Air Comfort (aircomfort.ac) appeared on a ransomware extortion site and data attributed to it has been published. If this is your organisation, or a supplier you depend on, the priority is to confirm the intrusion and contain it before the window to act closes.

  • Engage your incident-response team and preserve forensic evidence before remediating — do not wipe affected systems first.
  • Force a password reset and revoke active sessions for exposed accounts; rotate any credentials, API keys or certificates that may have been in the stolen data.
  • Assess regulatory notification duties (GDPR, NIS2, sector regulators) — many carry a 72-hour reporting clock from awareness.
  • Monitor for the data appearing on Rancoz's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.

How we know this. Darkfield monitors public ransomware leak sites continuously, archiving every new disclosure and the data later released against the victim. Each entry on this page is sourced from the operator's own publication and cross-checked against complementary OSINT feeds (RansomLook, ransomware.live, RansomWatch). We do not collect or host stolen data — only the metadata, timestamps and screenshots needed to make the public disclosure searchable and accountable. Records here are corrected when the original post is edited, retracted, or merged with another disclosure.
