Sometimes, when analyzing a company's data, you don't find what you're looking for. Other times, you find something you never expected to see.

Data leaks have one problem: they tend to be repetitive. Identical types of records belonging to different people leak from different companies. But every now and then, you come across something you never expected to find.
While analyzing the data, we discovered a set of documents that reveal interesting details about the company’s founding, as well as its connection to another staffing provider, .
According to the documents, the founders of Quest Group previously worked at Solomon Page before starting their own company. Apparently, at some point, they took a database with them, which later became the subject of legal disputes.

Disclosure context

About anubis

Anubis is a recently emerged ransomware group that began operations in February 2025, primarily motivated by financial gain through encryption and extortion attacks. The group has demonstrated rapid expansion, accumulating 65 documented victims within a short operational timeframe. Given the group's recent emergence, limited information is publicly available regarding their specific country of origin, organizational structure, or confirmed affiliations with other cybercriminal entities, though their operational patterns suggest they may operate as an independent group or small-scale ransomware-as-a-service operation. Their attack methodology appears to focus on opportunistic targeting across multiple geographic regions, with victims concentrated primarily in the United States, Australia, Canada, the United Kingdom, and France, indicating either English-language proficiency or the use of automated tools that facilitate cross-border operations. The group demonstrates a clear preference for targeting healthcare organizations and manufacturing companies, followed by business services and technology sectors, suggesting they prioritize organizations with critical operational dependencies that may be more likely to pay ransoms quickly. Due to the group's recent emergence in early 2025, there is insufficient publicly documented information from established cybersecurity firms or law enforcement agencies regarding their specific technical capabilities, encryption methods, or whether they employ double or triple extortion tactics involving data theft and leak sites. As of current reporting, Anubis remains an active threat with continued victim acquisition, though the full scope of their capabilities and long-term operational sustainability remains to be determined as security researchers continue to analyze their activities. The group has been linked to 113 public disclosures across our corpus. First observed on a leak site on February 25, 2025; most recent post September 18, 2026. The operation is currently active.

If your organisation is affected

A listing by anubis means Quest Group 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.
Monitor for the data appearing on anubis'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.
