[CLOP] – Ransomware Victim: KIER[.]CO[.]UK

AI Generated Summary of the Ransomware Leak Page

On November 7, 2025, a leak post attributed to the CL0P ransomware group identifies KIER.CO.UK as a victim. The entry describes KIER.CO.UK as a UK-based construction, property, and infrastructure company operating across sectors including defence, transportation, health, education, and utilities, offering services in construction and civil engineering as well as maintenance and refurbishment. The post frames the incident as a ransomware data-extortion event and notes that a claim link is present on the page for further information or negotiation. The page shows no downloadable data, attachments, or media; instead it presents a queue-style notice instructing visitors not to refresh and to expect automatic redirection, suggesting the listing is gating content rather than exposing leaked data. No compromise date is provided in the dataset; the posted timestamp (2025-11-07 14:38:54) should be treated as the post date.

From a threat intelligence perspective, the leak centers on KIER.CO.UK within the construction sector in the United Kingdom. The listing aligns with CL0P’s typical double-extortion approach, where attackers threaten public disclosure of stolen data and may seek ransom; however, the post itself does not specify a ransom amount, data size, or explicit encryption status. The page contains no visible screenshots or attachments, and there is a claim URL present for further contact, indicating potential negotiation outside the visible listing. The absence of posted data on this page means the exact scope of compromise cannot be confirmed from this listing alone. Given the victim’s industry and locale, organizations in construction and infrastructure should monitor for updates and review their data protection and incident readiness accordingly.
