Standard Building Supplies Ltd. Listed by everest Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The Standard Building Supplies Ltd. Listed by everest Ransomware Group (reported April 16, 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
Standard Building Supplies Ltd. was listed on the Everest ransomware leak site on April 16, 2022. The group claims to have stolen internal data during a ransomware attack. No further details on the timing of the intrusion, the volume of data, or the method of access have been made public. The number of people affected is not disclosed.
Who is everest?
Everest is a ransomware operator that uses a double-extortion model: it encrypts systems and also exfiltrates data, then posts samples or lists of victims on a dedicated leak site to pressure payment. The group has appeared in multiple public listings since at least 2020, typically targeting mid-sized organisations across various industries. Its listings constitute claims by the group rather than independently verified statements about any specific victim.
About Standard Building Supplies Ltd.
Standard Building Supplies Ltd. is a supplier of construction materials and related products. Organisations of this type routinely maintain records on trade customers, project specifications, pricing agreements, employee payroll information and supplier contracts. A breach at such a firm can therefore touch both commercial and personal data held in the ordinary course of business.
What was likely exposed
The only information released states that internal files were exfiltrated. The precise categories of data contained in those files have not been published. Companies in the building-supplies sector commonly store customer contact details, order histories, financial records and employee information, but it is not confirmed whether any of these specific categories were among the files taken in this case.
Why it matters
When internal files are removed from a supplier’s systems, the individuals and organisations named in those files face the possibility that their information could be used for fraud, targeted scams or further criminal activity. For the company itself, the incident adds operational costs for investigation, notification and remediation, regardless of whether a ransom demand was met.
If your data was in this claimed breach
Monitor bank and credit accounts for unusual activity and consider placing a fraud alert with credit reference agencies. Use a unique password for each important account and enable multi-factor authentication where available. Individuals can run a free exposure scan of their email address against known breach data to check whether their information appears in public listings from incidents such as this one.

Publicly posted by everest — 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.
