Sponseller Group, Inc. Listed by minteye Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Sponseller Group, Inc. was listed by the minteye ransomware group on December 12, 2025, after internal files were exfiltrated in a ransomware attack. Individuals should check the company’s official notices to determine whether their information was exposed and take any recommended protective steps.
Inside the incident
The incident came to light solely through minteye’s listing of Sponseller Group, Inc. The group asserts that internal files were removed during a ransomware operation and states the total volume reached 300 GB. No timeline for the intrusion, method of initial access, or subsequent actions by the organization has been released. The number of people whose information may be involved is currently unknown.
Who is minteye?
Minteye is a ransomware operation that maintains a public leak site where it lists organizations it claims to have targeted. Such groups typically encrypt systems, exfiltrate data, and then pressure victims by threatening to publish the material. The group’s listing of Sponseller Group, Inc. constitutes an unverified claim by the actor; no additional statements or evidence specific to this case have been attributed to minteye beyond the site entry itself.
Who is Sponseller Group, Inc.?
Sponseller Group, Inc. is a private organization whose precise sector and operations are not detailed in public breach records. Companies of this type routinely maintain records related to clients, employees, financial transactions, and internal communications. A claimed compromise of this scale draws attention because such entities often serve as custodians of information that can affect both individuals and business partners if disclosed.
What data was at risk
The only data category named in connection with the listing is internal files removed during the reported ransomware activity. The exact nature, sensitivity, or contents of those files have not been disclosed. Organizations in this category commonly store employee records, contractual documents, and operational data, yet the specific composition in this instance remains unconfirmed.
- 300 GB reported volume of internal files
- Listed December 12, 2025

What's at stake
Exposed internal files can contain details that enable further targeting of individuals or the organization itself, such as account credentials, contact information, or proprietary records. For the company, the incident may lead to regulatory scrutiny, remediation costs, and loss of trust from clients or partners. Individuals whose information appears in the files face the possibility of follow-on fraud or phishing attempts, though the scale of any such exposure is not yet known.

Publicly posted by minteye — unverified claim, pending independent verification
Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
