Disclosure context

About bravox

Bravox is an emerging ransomware group first observed in February 2026, operating with apparent financial motivations based on their targeting patterns and victim selection. The group has claimed responsibility for attacks against at least 9 organizations, though limited public reporting exists regarding their specific origin, country of operation, or confirmed affiliations with other cybercriminal groups. Based on available victim data, Bravox demonstrates a preference for targeting organizations in the United States, Switzerland, France, and Canada, with particular focus on healthcare and agriculture/food production sectors, though their victim profile also includes entities from unspecified industry verticals. Due to the group's recent emergence and limited documented activity, detailed information regarding their specific attack methodologies, initial access vectors, encryption techniques, or use of double extortion tactics has not been extensively reported by major security firms or law enforcement agencies. Given the recency of their first observed activity in early 2026, comprehensive analysis of notable campaigns, major victim organizations, or law enforcement disruption efforts remains limited in publicly available threat intelligence reporting. The group's current operational status appears active based on the timeline of their emergence, though their relatively small victim count and limited public visibility suggest they may be a smaller-scale operation compared to more established ransomware groups. The group has been linked to 22 public disclosures across our corpus. First observed on a leak site on February 11, 2026; most recent post July 7, 2026. The operation is currently active.

If your organisation is affected

A listing by bravox means PB Fiduciaire SA 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, NCSC-CH (Switzerland), as required for your jurisdiction.
Monitor for the data appearing on bravox'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.
