Keidel Supply Company Incorporated Data Breach

Keidel Supply Company Incorporated, a wholesale plumbing and kitchen product distributor based in Cincinnati, Ohio, was added to the dark web portal of the N0n ransomware group on October 25, 2026. The listing was identified through SOCRadar’s Dark Web Monitoring service and appeared as part of a batch that includes several other U.S. manufacturing and industrial organizations. Keidel Supply serves contractors, builders, and commercial clients across the Midwest, placing the company within the supply chain that supports residential and commercial construction throughout the region. The composition of the batch, dominated by American industrial and distribution-sector names, reflects sustained extortion interest in this part of the U.S. economy. Over the 60 days preceding this listing, N0n posted victims regularly across Manufacturing, Professional Services, Healthcare, and Technology, with U.S.-based companies making up the bulk of its victim portfolio. Mid-market distributors and supply chain firms appeared with some frequency during this period. Other victims published in the same October 25 batch include Pure Grow Diamonds Inc., a U.S. Manufacturing company, and Technoleads Services Inc., a Technology company based in Canada. Keidel Supply’s profile — domestic, mid-market, and distribution-focused — is consistent with N0n’s observed targeting pattern, and its appearance alongside other U.S. industrial organizations in the same batch reinforces that alignment.

SOCRadar’s stealer-log query for the Keidel Supply Company domain returned no records. Stealer logs are collections of credentials harvested by infostealer malware that surface in underground channels, and they are routinely checked to determine whether a named organization’s credentials are already circulating. In this case, no entries associated with the company’s corporate domain were found in the queried dataset. The result carries explicit limitations: the stealer-log dataset is a paginated sample rather than a complete corpus, so the check covered only a limited portion of the available records, and credentials could exist under a different spelling of the corporate domain or be tied to a staff member’s personal email alias, in which case they would not surface under the primary domain that was queried. A null stealer-log result does not confirm that Keidel Supply is unaffected. Absence of evidence in this dataset is not evidence that no compromise occurred: the paginated sample means relevant records may fall outside the portion queried, and exposures logged under alternate domain spellings or personal aliases would be missed by a domain-level search. The finding should therefore be treated as one data point rather than as clearance. N0n’s leak-site listing remains the primary indicator in this case, and such listings cannot always be independently verified; the lack of supporting credential telemetry neither corroborates nor refutes the group’s claim at this stage. Given these limitations, continued dark web and stealer-log monitoring is the appropriate posture while the claim remains unverified. Follow-up credential-hygiene checks should extend beyond the primary corporate domain to alternate domain spellings and personal email aliases used by staff, since these are the specific paths by which an exposure could evade a domain-level query. Monitoring for any subsequent data publication or additional victims named by N0n will help determine whether the listing is accompanied by leaked material. No positive signal of compromise was observed in the queried telemetry, but the null result should be revisited over time rather than treated as a final assessment.
