CFGI Management, a U.S.-based accounting and business advisory firm headquartered in Massachusetts, was named on March 9, 2026 as a victim of the data-extortion group ShinyHunters. The attackers claimed responsibility on a dark-web leak site and have been linked by researchers to a broader threat-actor cluster tracked as Scattered Lapsus$ Hunters or UNC6661, which has been active in identity-based intrusions throughout early 2026.\n\nPublic reporting on the leaked dataset describes more than 800,000 records exfiltrated, including a subset of approximately 373,000 unique personal records covering names, work and personal email addresses, phone numbers, and home addresses. Independent analysis of the listing also describes more than 40,000 corporate documents in the dump, alongside system-integration metadata mapping internal Salesforce, NetSuite, and employee identifiers. The presence of integrated identity-system data suggests the attackers obtained access through compromised single-sign-on or identity-provider credentials.\n\nThe exposure carries unusually severe downstream risk because CFGI works closely with corporate finance leadership at mid-market and Fortune 500 clients. The combination of CFGI personnel identity, project metadata, and authentic internal mappings provides a strong foundation for highly convincing business email compromise targeting CFGI's clients. Anyone associated with CFGI, including current and former staff, contractors, and client-side counterparts, should be alert to email or call-based requests referencing CFGI projects, accounting deliverables, or financial system access, and verify any such request through an established voice channel rather than a reply link or new email thread.

Financial consulting and business advisory firms maintain employee, client, prospect, and corporate contact records, including names, business and personal emails, phone numbers, and mailing addresses across engagement and operational systems.

The breach surfaced publicly on March 9, 2026, when the data-extortion group ShinyHunters posted CFGI on its dark-web leak site. Public reporting in the immediate aftermath linked the campaign to a broader cluster tracked by researchers as Scattered Lapsus$ Hunters or UNC6661, which has conducted a series of identity-based attacks against high-profile organizations through early 2026. U.S. plaintiff law firms began organizing class-action investigations within days of the disclosure. As of the publication of these notes, CFGI has not issued a detailed public statement about the incident, and the full scope of compromised data is not yet confirmed.
