Nichino Ryokka Co Ltd Listed by Hunters Ransomware Group

On February 11, 2025, Japanese agricultural chemicals manufacturer Nichino Ryokka Co Ltd appeared on the leak site of the hunters ransomware group, with the attackers confirming they had both exfiltrated and encrypted the company’s internal files.

What Public Reporting Shows

Public reporting indicates the listing includes samples of stolen data, though the precise volume and full list of victims remain unclear. The hunters group’s site states that Nichino Ryokka’s systems were both encrypted during the ransomware deployment and that copies of internal files were taken prior to encryption. No confirmed customer or employee records have been publicly detailed in the initial posting, but the presence of the company on a ransomware leak site means any data held in those internal files must now be treated as at risk of exposure.

Available reporting describes the incident as following the group’s standard double-extortion model: deploy ransomware, encrypt systems, threaten to publish stolen data unless a ransom is paid. As of the publication date, it is not known whether Nichino Ryokka has engaged with the attackers or paid any demand.

Why This Matters for You and Your Family

Even when a breach hits a business rather than a consumer app, ordinary families feel the impact. If you or anyone in your household has ever done business with Nichino Ryokka, worked there, or had your information stored in supplier or partner systems, your personal details could now sit inside the exfiltrated files. Internal files often contain spreadsheets of customer contacts, vendor lists, employee directories, or invoices — all of which can be mined for names, addresses, phone numbers, email accounts, and financial references.
