Sonae Listed by ransomexx Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The Sonae Listed by ransomexx Ransomware Group (reported April 5, 2022) is an unverified claim; the data involved is undisclosed belonging to roughly unknown people. If you have an account with them, your information may now be circulating on the open web and with data brokers. Here’s exactly what happened, how to check if you were affected, and what to do next.
What happened
On 5 April 2022, Sonae appeared on the leak site maintained by the ransomware group ransomexx. The entry stated that internal files had been exfiltrated. No further details on the timing of the intrusion, the volume of data, the method of access, or any ransom demand have been made public.
Who is ransomexx?
Ransomexx is a ransomware operation that first appeared in public reporting around 2020. The group typically uses encryption to disrupt operations and maintains a leak site where it lists organisations from which it claims to have stolen data. Listings on the site serve as a pressure tactic when ransom negotiations stall. The group has previously claimed responsibility for incidents affecting companies in multiple sectors and countries. In this case the group claims to have taken internal data from Sonae; that claim has not been independently verified in public reporting.
About Sonae
Sonae is a Portuguese retail and services conglomerate whose operations include supermarkets, shopping centres, telecommunications and technology businesses. Organisations of this scale routinely process customer records, supplier information, employee data and internal operational documents. A breach at such a company can therefore touch both commercial records and personal information belonging to large numbers of individuals.
What was likely exposed
The only detail released is that internal files were allegedly exfiltrated. The exact categories of data contained in those files have not been disclosed. Companies in retail and telecommunications commonly hold names, contact details, purchase histories, loyalty-programme records and employee information, but it is not confirmed whether any of these types were among the material allegedly taken from Sonae.
Why it matters
When internal files are removed during a ransomware incident, the material can contain sensitive business information or personal data. Individuals whose records appear in such files may face risks of fraud or targeted scams if the data later circulates. For the organisation, the incident adds operational disruption and potential regulatory scrutiny under data-protection rules that require notification when personal data is compromised.
If your data was in this claimed breach
Monitor bank and credit-card statements for unusual activity and consider placing fraud alerts with credit-reference agencies. Use unique passwords for important accounts and enable multi-factor authentication where available.

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.
