riken-nosan.com Listed by lockbit2 Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The riken-nosan.com Listed by lockbit2 Ransomware Group (reported May 13, 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.
On May 13, 2022, the domain riken-nosan.com appeared on a leak site operated by the LockBit2 ransomware group. The listing states that internal files were taken during a ransomware incident; no further details on the number of records, the method of access, or confirmation of the data’s authenticity have been made public.
The incident is significant because any confirmed exfiltration of internal files from an organisation in the agricultural or food sector can affect supply-chain records, employee information, and business correspondence that are not normally visible to the public.
What happened
The only confirmed public record is the May 13, 2022 listing on the LockBit2 leak site. The group claims to have stolen internal data; the organisation has not issued a statement confirming or denying the claim. The number of people affected, the precise date of the intrusion, the encryption status of systems, and any ransom demand or payment remain undisclosed.
Who is lockbit2?
LockBit is a ransomware-as-a-service operation that first appeared in 2019 and has released multiple variants. The group typically gains access through phishing, stolen credentials or unpatched remote-desktop services, deploys encryption across victim networks, and exfiltrates selected files. When a ransom is not paid, the operators publish file samples or directory listings on a Tor-based leak site to pressure the victim. The group’s listings are claims until independently verified; many organisations listed have later confirmed incidents, while others have disputed the extent of data taken.
About riken-nosan.com
Riken-nosan.com is the public website of a Japanese company operating in the agricultural and food-products sector. Organisations of this type routinely maintain records of suppliers, production volumes, customer orders, employee payroll data and regulatory compliance documents. A breach at such an entity can therefore expose both commercial information and personal data belonging to staff or business partners.
What was likely exposed
The listing refers only to “internal files exfiltrated in ransomware attack.” No inventory of file types or data categories has been released. Companies in this sector commonly store employee identifiers, contact details, financial spreadsheets and operational documents; whether any of these categories were among the claimed files is unconfirmed.
Why it matters
Exposure of internal files can lead to follow-on fraud, targeted phishing of employees or partners, or competitive intelligence gathering. If personal identifiers are present, affected individuals face a modest but real increase in the risk of identity misuse. For the organisation, the incident may trigger regulatory notification requirements in Japan and could affect relationships with suppliers who shared data under confidentiality terms.
If your data was in this claimed breach
Monitor bank and benefits statements for unusual activity and enable multi-factor authentication on any accounts that reuse passwords. Request a copy of your employment or customer records from the organisation to understand what information they hold. Readers can also run a free exposure scan of their email address against known breach data sets to check for prior appearances of their information.

Publicly posted by lockbit — 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.
