Disclosure context

About Vexy Ransomware

Vexy Ransomware is a newly observed ransomware group first identified in September 2026 with limited public documentation available from major threat intelligence sources at this time. Based on available data, the group appears to be financially motivated, consistent with the broader ransomware ecosystem. With only a single confirmed victim recorded, Vexy remains an emerging or low-volume threat actor, though its targeting of the Energy and Utilities sector in Brazil warrants monitoring given the critical infrastructure implications of attacks against that vertical. No attributable country of origin, RaaS affiliation, or organizational links to established ransomware groups have been publicly confirmed by CISA, FBI, Mandiant, or equivalent reputable research bodies as of the time of this writing. Similarly, specific details regarding initial access vectors, tooling, encryption methodology, or data exfiltration practices have not been publicly documented, and no notable high-profile campaigns or law enforcement actions have been recorded against this group. Given the group's nascent activity profile and single known victim, Vexy should be assessed as an emerging threat requiring continued observation, particularly for organizations operating within the Brazilian energy and utilities sector, as escalation in victim count or geographic and sectoral expansion may indicate maturation of the group's operational capabilities. The group has been linked to 13 public disclosures across our corpus. First observed on a leak site on September 3, 2026; most recent post September 12, 2026. The operation is currently active.

If your organisation is affected

A listing by Vexy Ransomware means Logar Network Solutions 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, CERT.br (Brazil), as required for your jurisdiction.
Monitor for the data appearing on Vexy Ransomware'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.
