sumacinc.com Listed by incransom Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
sumacinc.com has been listed by the incransom ransomware group, with internal files reported exfiltrated in an attack. The listing came to light on April 28, 2026, and an undisclosed number of people may be affected; anyone who has interacted with the organization should check for signs of exposure and take protective steps.
What happened
The incident came to public notice through the April 28, 2026 listing. The group states that files were removed from sumacinc.com systems in the course of a ransomware operation. No further details on the date of the intrusion, the method of access, or the precise volume of data beyond the reported 2 terabytes have been disclosed. The number of people whose information may be involved remains unknown.
The group behind it: incransom
Incransom is a ransomware operator that maintains a leak site to publish material taken from targeted organizations. Such groups commonly encrypt systems and threaten to release stolen files when ransom demands are not met. The listing of sumacinc.com constitutes the group’s claim that it obtained the described data; independent confirmation of the claim has not been reported.
About sumacinc.com
Sumacinc.com is the online presence of an incorporated organization that maintains client records in the course of its operations. Entities of this type routinely store contact details, account information, and other records necessary to deliver services. Exposure of such holdings can affect both the organization and the clients whose data it holds.
The information in question
The listing identifies the material as internal files exfiltrated in a ransomware attack and summarizes the contents as all client data amounting to 2 terabytes. No additional categories of data have been specified. The exact composition of the files therefore remains unconfirmed beyond the description provided in the claim.
The real-world impact
Client records held by service organizations can include details that, if released, may be used for targeted fraud or unauthorized account access. The organization itself faces operational disruption from the ransomware component and potential regulatory or contractual obligations tied to the protection of client information. Because the number of individuals involved is undisclosed, the full scope of downstream effects cannot yet be measured.
If your data was in this claimed breach
Monitor financial and online accounts for unusual activity and change passwords for any services linked to the affected organization. Enable multi-factor authentication where available. Individuals may also run a free exposure scan of their email address against known breach data to determine whether their information appears in publicly referenced listings.

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.
