Storage King Listed by anubis Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

Ransomware groups continue to target organisations that hold customer records and operational data, using double-extortion tactics that combine encryption with public leak-site listings. In this environment, even listings that provide limited technical detail can create lasting uncertainty for individuals whose information may have been involved.

Storage King has been listed by the ransomware group anubis, according to a report dated 30 September 2025. The listing claims a major personal data leak involving internal files exfiltrated during a ransomware attack. The number of people affected remains unknown, and public detail on the precise scope is limited. The incident matters because organisations of this type routinely process personal and contractual information that, if exposed, can lead to identity misuse, targeted fraud or further social-engineering attempts.

What happened

On 30 September 2025 it was reported that Storage King had been listed by the anubis ransomware group. The group claims that internal files were exfiltrated as part of a ransomware attack and characterises the event as a major personal data leak. No confirmed figures for the number of individuals affected have been released, and the exact method of initial access, the volume of data taken, and any ransom demand remain undisclosed in the available public record. The listing itself constitutes a claim by the group rather than an independently verified confirmation of every asserted detail.

The group behind it: anubis

Anubis is a ransomware operation that has appeared in public threat reporting as a group employing double-extortion techniques: encrypting systems while simultaneously threatening to publish stolen data on a dedicated leak site if payment is not made. Like many contemporary ransomware actors, anubis typically seeks to maximise pressure by combining technical disruption with reputational and regulatory risk for the victim organisation. Public documentation of the group’s prior activity shows a pattern of listing companies across multiple sectors and claiming exfiltration of internal documents, customer records and operational files. In the present case the group claims Storage King as a victim and asserts that internal files were taken; no further specific statements by anubis about this particular organisation beyond the listing itself are recorded in the facts available.

Who is Storage King?

Storage King is a commercial self-storage provider. Companies in this sector offer secure units for personal and business belongings and, in the ordinary course of operations, collect and retain customer identification details, contact information, payment records, access credentials and contractual documentation. Because these organisations act as custodians of both physical property and associated personal data, a breach can affect not only the company’s own operations but also the privacy and security of the individuals who entrust them with that information. The consequential nature of such an incident therefore stems from the sensitivity of the records typically held rather than from any publicly established finding of fault.

The information in question

The available facts state that internal files were exfiltrated in a ransomware attack and that the event has been described as a major personal data leak. Exact data types beyond this description have not been disclosed. Organisations operating self-storage facilities commonly hold names, addresses, telephone numbers, email addresses, payment-card or bank details, identity-document copies, access-code records and lease agreements. Whether any or all of these categories were present among the files claimed by anubis remains unconfirmed. Public detail is therefore limited to the group’s assertion of exfiltration and the characterisation of the material as personal data; no inventory of specific fields or file counts has been released.

The real-world impact

For individuals whose information may have been among the internal files, the principal risks are identity theft, account takeover and phishing campaigns that leverage accurate personal details. Even partial records can be combined with data from other breaches to create more convincing social-engineering attempts. For Storage King the consequences include potential regulatory scrutiny, notification obligations, remediation costs and reputational damage arising from the public listing. Because the number of people affected is unknown and the precise contents of the exfiltrated files remain unconfirmed, the scale of these impacts cannot yet be quantified. Affected parties may face prolonged uncertainty while investigations and any subsequent disclosures proceed.

Were you affected?

If you are a current or former Storage King customer, monitor financial statements and credit reports for unfamiliar activity, enable multi-factor authentication on important accounts, and treat unsolicited communications that reference storage services with caution. Change passwords associated with any accounts that share credentials used for Storage King services. Readers can also run a free exposure scan of their email address to check whether their information has already surfaced in known breach data sets. Stay alert for official notifications from the company or relevant authorities, as further Reported Details may emerge over time.
