No confirmed evidence, only a leak-site claim tracked by RansomLook

What happened

The majinahanashi ransomware group claims Magasin du Nord (listed as “Magasin”) as a victim on its leak site. The claim is recorded by the tracker RansomLook, which dates the post 2026-11-05 and marks it with the status “LEAK”.

According to the group’s post as captured by RansomLook, the group says the company was offered a decryptor, test files, a fixed price and two deadline extensions. The group also says it holds an archive of “over 280,000 files (70 GB)”. RansomLook’s listing shows “Files: 280481 / 70.2 GB” and one attachment.

What is not confirmed:

  • Magasin du Nord has not confirmed an incident in the available sources.
  • No independent outlet has verified the claim. The only source is a leak-site tracker.
  • The entry point, the type of data and the real data volume are not confirmed.
  • Whether any data has actually been published is not confirmed.

Am I affected?

Not confirmed. The sources do not say which systems, customers, employees or partners, if any, are involved. A ransomware group’s leak-site listing is a claim, not proof of a breach.

What to do now

  1. Watch for an official statement or notification from Magasin du Nord before acting on the claim.
  2. If you are responsible for a business relationship with Magasin du Nord, ask the company through your usual contact whether it is investigating.
  3. Do not download or open files offered on leak sites.
