[WORLDLEAKS] – Ransomware Victim: Kobayashi

AI Generated Summary of the Ransomware Leak Page

On November 1, 2025, a ransomware leak post attributed to the Worldleaks group publicly identifies Kobayashi as a victim. The post date in the metadata is 2025-11-01 09:08:13.000000, and no separate compromise date is provided, so this timestamp should be treated as the post date. The page describes Kobayashi as a Japanese company that manufactures and sells over-the-counter drugs, oral hygiene products, and other healthcare items with a global footprint. Although the industry field in the metadata is not filled, the narrative text presents the victim as a pharmaceutical manufacturer with a diversified product lineup. The post does not disclose a ransom amount, nor does it clearly state whether encryption occurred or data was exfiltrated in the visible content. The leak page shows no screenshots or downloadable files—the counts for images and downloads are zero. There is an indication that a claim URL is present on the page for additional details, though no specific URLs are included in this summary.

The page’s visible content concentrates on identifying the victim and outlining a broad business description rather than presenting data artifacts. The page indicates the location as Japan, and attributes the incident to Worldleaks. With no explicit compromise date, encryption status, or ransom figure disclosed, the exact impact remains unconfirmed from this post alone. The post contains no images or attachments, and there are currently no visible data samples on the page. Given the presence of a claim URL but the lack of attached data on the page, readers should monitor for follow-up disclosures or additional leak updates to determine the scope of the breach and any potential data exposure.
