Attack summary

Severity: high — Data has been confirmed as published by the ransomware group, indicating actual exfiltration and public release of internal business data from a specialised energy-sector manufacturer. While no explicit PII-at-scale or regulated medical/government data is confirmed, the published status and sensitive industrial/commercial data of an energy-sector supplier warrants a high severity rating.

Vice Society claims to have published data exfiltrated from Sub-Drill, with the disclosure status listed as data_published, indicating stolen data has been released rather than merely threatened. No ransom amount or specific data volume was stated in the leak post.

Disclosure context

About Vicesociety

Vicesociety is a ransomware group that emerged in May 2021, primarily motivated by financial gain through targeting critical infrastructure and public service organizations. The group's origin and specific affiliations remain largely undetermined by public threat intelligence reporting, though their operational patterns suggest they function as an independent ransomware operation rather than a established RaaS model. Vicesociety primarily gains initial access through exploitation of public-facing applications and credential-based attacks, with documented cases showing they particularly focus on compromising remote access services and vulnerable web applications before deploying their ransomware payload across victim networks. The group has demonstrated a clear preference for targeting educational institutions, government agencies, and healthcare organizations, with their 188 documented victims concentrated heavily in the United States, United Kingdom, Germany, Australia, and Spain, indicating a focus on English-speaking and Western European entities. While specific high-profile campaigns have not been extensively detailed in major public threat intelligence reports from CISA or FBI advisories, the group's consistent targeting of critical sectors like education and healthcare has drawn attention from security researchers monitoring threats to essential services. Vicesociety remains active as of recent threat intelligence assessments, continuing their operations against similar target sectors with no documented law enforcement disruption or significant operational changes. The group has been linked to 188 public disclosures across our corpus. First observed on a leak site on May 31, 2021; most recent post June 20, 2023. The operation is currently inactive.

If your organisation is affected

A listing by Vicesociety means Sub-drill Supply 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, CISA (United States), as required for your jurisdiction.
Monitor for the data appearing on Vicesociety'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.
