Disclosure context

About brotherhood

The Brotherhood ransomware group is a recently emerged financially-motivated cybercriminal organization first observed in October 2025, representing one of the newer entrants in the ransomware landscape. Given the group's recent emergence and limited public documentation from major security firms and law enforcement agencies, detailed information about their origin, country of operation, and specific affiliations remains largely unknown to open-source intelligence. Based on observed targeting patterns, the group appears to employ opportunistic attack methodologies, focusing primarily on English-speaking markets including the United States, Australia, and Canada, while also targeting victims in Germany and Switzerland, suggesting either broad-spectrum initial access capabilities or acquisition of access through underground markets. Their victim selection spans multiple sectors including business services, construction, transportation and logistics, and technology companies, indicating a non-discriminatory approach typical of many financially-motivated ransomware operations rather than targeted campaigns against specific industries. With only 18 documented victims since their October 2025 emergence, Brotherhood represents a relatively small-scale operation compared to established ransomware groups, and specific details regarding their encryption methods, data exfiltration practices, or extortion tactics have not been publicly documented by major threat intelligence providers. The group remains active as of the latest available intelligence, though their limited operational footprint and recent emergence means comprehensive analysis of their tactics, techniques, and procedures awaits further documentation by security researchers and law enforcement agencies. The group has been linked to 18 public disclosures across our corpus. First observed on a leak site on October 10, 2025; most recent post January 6, 2026. The operation is currently active.

If your organisation is affected

A listing by brotherhood means Integlia 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.
  • Report the incident to your national CERT, CCCS (Canada), as required for your jurisdiction.
  • Monitor for the data appearing on brotherhood'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.
