NIJMAN / ZEETANK International Transport Sp. z o. o. Listed by avaddon Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The NIJMAN / ZEETANK International Transport Sp. z o. o. Listed by avaddon Ransomware Group (reported September 9, 2021) 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.
Inside the incident
The incident came to light solely through the avaddon leak site on 9 September 2021. The group claims to have obtained internal files during a ransomware intrusion at NIJMAN / ZEETANK International Transport Sp. z o. o. No additional technical details, such as the initial access vector, the duration of access, or the scale of the data set, have been made public by either the organisation or the group.
Who is avaddon?
Avaddon is a ransomware operation that emerged in 2020 and adopted a double-extortion model. After encrypting systems, the group copies selected files and posts sample material or file listings on a dedicated leak site to pressure victims into paying. The group has published data belonging to organisations in multiple countries and sectors, typically after a period of negotiation has failed. Its listings are presented as claims rather than independently verified events.
Who is NIJMAN / ZEETANK International Transport Sp. z o. o.?
NIJMAN / ZEETANK International Transport Sp. z o. o. is a Polish-registered company whose name indicates involvement in cross-border road transport and logistics. Firms of this type routinely maintain records that include shipment documentation, customer contact details, driver and employee information, vehicle data, and commercial contracts. A successful intrusion at such an operator can therefore expose both personal and commercially sensitive material that is not normally available to the public.
What data was at risk
The only description supplied is that internal files were allegedly exfiltrated. No inventory of file categories or data fields has been released. Organisations in the international transport sector commonly store names, addresses, identification numbers, financial references, and operational logs; however, whether any of these specific categories were present in the material claimed by avaddon is unconfirmed.
The real-world impact
Individuals whose details reside in the affected files may encounter attempts to misuse that information for fraud or targeted scams. The organisation itself faces potential operational disruption, regulatory scrutiny under data-protection rules, and loss of commercial confidentiality. Because the exact scope of the data remains unknown, the full extent of these consequences cannot yet be measured.
If your data was in this claimed breach
Review bank and credit statements for unusual activity and consider placing fraud alerts with relevant credit agencies. Change passwords for any accounts that may have been referenced in company records and enable multi-factor authentication where available. Readers can also run a free exposure scan of their email address against known breach data sets to determine whether their information has appeared in previously published collections.

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.
