Date of data breach:

September 18, 2026

by: Almeida Law Group

Attorneys at Almeida Law Group are investigating whether a class action lawsuit can be filed on behalf of individuals affected by a possible Quest Group data breach. According to dark web monitoring sources, a hacker group calling itself anubis claimed responsibility for a cyberattack on Quest Group in a post first observed in September 2026, alleging it had gained access to internal company systems. As of this writing, Quest Group has not issued a public confirmation of the incident, and the exact scope of any exposed data remains unknown. If you believe you were affected, contact Almeida Law Group.

About Quest Group

What Happened?

On September 18th, 2026, the Anubis ransomware group posted a dark web claim alleging it had compromised Quest Group. The claim was tracked by Ransomware.live and describes the purportedly obtained data as “employee data, internal files, and a few unexpected discoveries.” This remains an unverified attacker-side allegation. No confirmation from Quest Group, any regulatory body, or independent journalism has been found. The specific types of data that may have been affected were not identified in any confirmed source, and the claim description used by Anubis appears to be templated language also used in other group postings.

Anubis is a ransomware-as-a-service (RaaS) operation first observed in late 2024, originally operating under the name Sphinx. As of mid-September 2026, the group had publicly claimed approximately 108 victims. Anubis is known to target organizations in healthcare, manufacturing, and professional services, and employs a double-extortion model. Researchers at Arctic Wolf have documented Anubis initial access techniques including exploitation of CitrixBleed 2 (CVE-2025-5777) and abuse of VPN infrastructure. The group also features an optional “wipe mode” that permanently destroys data rather than encrypting it. No prior cybersecurity incidents or litigation specific to Quest Group were identified in supplemental research.
