asseco-ce.com Listed by ALP-001 Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
asseco-ce.com was listed by the ALP-001 ransomware group on April 03, 2026 after internal files were exfiltrated in a ransomware attack. An undisclosed number of people may be affected; individuals are advised to check if their information was exposed and take appropriate protective steps.
On April 3, 2026, the ransomware group ALP-001 listed asseco-ce.com on its leak site, stating that internal files had been taken during a ransomware operation. The number of individuals whose information may be involved remains unknown, and the organisation has not confirmed the incident. The listing includes a claim that 24 gigabytes of sample data are available for download from the group’s page, with a deadline set for April 11, 2026.
The practical stakes centre on the exposure of internal records from a regional software provider whose systems support government and commercial clients across Central Europe. Any confirmed release of those files could place operational documents, client-related material, or employee information into circulation without the consent of the people or entities named in them.
Breaking down the breach
The only public record of the event is the April 3 listing itself. It identifies the target as Asseco Central Europe, notes a total claimed storage volume of 230 gigabytes, and asserts that internal files were exfiltrated. No independent confirmation of the volume, the method of access, or the precise date of the intrusion has been released. The organisation’s response, if any, has not been made public.
The group behind it: ALP-001
ALP-001 is a ransomware operator that maintains a leak site to publish data from organisations that do not meet its payment demands. Groups of this type typically gain initial access through compromised remote-access services or supply-chain weaknesses, then move laterally to locate and copy files before deploying encryption. The listing of asseco-ce.com follows the group’s standard pattern of posting a victim name, a claimed data volume, and sample files as pressure for payment. No statement from ALP-001 beyond the leak-site entry has been verified in connection with this target.
asseco-ce.com and its sector
Asseco Central Europe develops and maintains software used by public administration, financial institutions, and healthcare providers in Slovakia, the Czech Republic, Hungary, Germany, Austria, and Switzerland. Companies in this sector routinely process large volumes of citizen records, payment data, and internal business correspondence as part of contracts with government bodies. A compromise at such a firm therefore carries the possibility of affecting data that originates from multiple client organisations rather than from the software house alone.
The information in question
The listing describes the material only as “internal files exfiltrated in ransomware attack.” No inventory of specific file types, databases, or categories of personal information has been published by either the group or the organisation. While software vendors of this scale commonly store project documentation, configuration files, employee records, and client-supplied datasets, the exact contents of the claimed 230-gigabyte archive remain unconfirmed.
Why it matters
Internal files from a systems integrator can contain references to third-party infrastructure, authentication details, or personal data belonging to end users of the software. If released, such material could be used for further targeted attacks or for identity-based fraud. For the organisation, the incident adds to the operational burden of incident response, regulatory notification, and potential contract reviews with clients who rely on the confidentiality of their data.
Were you affected?
Individuals who have interacted with Asseco Central Europe clients or services have no direct way to confirm exposure from the current public record. A practical first step is to monitor official statements from the company and from data-protection authorities in the affected countries. Readers can also run a free exposure scan of their email address against known breach datasets to check for prior appearances of their information in other incidents.

Publicly posted by alp-001 — 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.
