Suma Sklep Listed by thegentlemen Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Suma Sklep was listed by thegentlemen ransomware group on April 19, 2026, after internal files were exfiltrated in an attack whose timing remains unknown. Individuals are advised to check whether their information was exposed and to take appropriate protective steps.
What happened
The listing appeared on the group’s site on the reported date. The only detail provided is that internal files were allegedly exfiltrated during a ransomware attack. No confirmation of encryption, ransom demand, or data volume has been made public, and the company has not issued a statement on the incident.
Inside thegentlemen
Thegentlemen is a ransomware operation that publishes victim names on a dedicated leak site when negotiations fail or ransoms remain unpaid. Groups of this type commonly gain initial access through phishing, exposed remote services, or compromised credentials, then move laterally to locate and copy data before deploying encryption. Their public listings serve as pressure tactics rather than verified technical disclosures.
Who is Suma Sklep?
Suma Sklep operates the Polish B2B platform Suma24.pl, which supplies professional cleaning products, catering equipment, and hygiene systems to the HoReCa and food-industry sectors. The store is run by Suma Service, a family-owned business established in 1995 and based in Koszalin. It supports 24/7 ordering, multiple payment methods, and services such as technical consulting and partnership programs. Organizations in this sector routinely store supplier records, customer account details, order histories, and internal operational documents.
What was likely exposed
The only information released is that internal files were allegedly exfiltrated. The exact categories of data contained in those files have not been disclosed. Companies of this type typically hold business contact information, order and invoice records, and administrative documents; whether any of these specific items appear in the exfiltrated material remains unconfirmed.
Why it matters
Exposure of internal files can reveal commercial relationships, pricing arrangements, and operational procedures that affect both the company and its clients. For individuals whose information appears in such records, the main practical concerns are potential misuse of contact details or account credentials in targeted campaigns. The absence of a confirmed data count leaves the scale of any downstream impact unknown at present.
What to do if you're exposed
Individuals who have done business with Suma Sklep should monitor their email and financial accounts for unusual activity and consider changing passwords on any accounts linked to the company. Enabling multi-factor authentication where available adds a further layer of protection.

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.
