The leak post

captured from the group's site

VR Advogados, a Brazilian law firm, neglected its clients’ personal data, violating laws regarding data storage and confidentiality—they posted and shared all of their clients’ documents, passport information, and powers of attorney via a Discord server. We hacked it. Now we have 3,000 documents belonging to all of their clients—passports, powers of attorney, declarations, personal and work-related correspondence, and more. The firm hasn’t responded to us for three days; if this continues, we’ll start selling the data.

Disclosure context

About Barracuda

Barracuda is a ransomware group first observed in August 2026 with an apparent primary motivation of financial gain, though limited public reporting exists given its recent emergence and relatively small confirmed victim count of four organizations. The group's country of origin and potential affiliations with established threat actors or ransomware-as-a-service ecosystems have not been publicly confirmed by CISA, the FBI, Mandiant, or other reputable security research organizations at this time. Based on available victim telemetry, Barracuda has demonstrated a targeting pattern focused on manufacturing, healthcare, and technology sector organizations, with victim distribution concentrated across China, the United States, and South Korea, suggesting either opportunistic targeting within these regions or deliberate selection based on perceived ransom-paying capacity; specific details regarding initial access vectors, tooling, encryption methodology, or data exfiltration practices remain undocumented in open-source reporting. No major high-profile campaigns, record ransom demands, or law enforcement actions against the group have been publicly documented, which is consistent with the group's nascent operational timeline and low confirmed victim count. Given its first observation date of August 2026 and the absence of substantial public intelligence, Barracuda should be considered an emerging and closely monitored threat whose full capabilities, affiliations, and operational scope remain to be established through continued tracking by the security research community. The group has been linked to 14 public disclosures across our corpus. First observed on a leak site on August 6, 2026; most recent post August 17, 2026. The operation is currently active.

If your organisation is affected

A listing by Barracuda means RS Automation appeared on a ransomware extortion site and is being pressured to pay before any publication. 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, KrCERT/CC (South Korea), as required for your jurisdiction.
Monitor for the data appearing on Barracuda'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.
