Am I affected?

Not confirmed. The available source does not say what data, if any, is involved, or which customers, partners or staff could be affected.

What to do now

  1. Watch for an official statement from Mutares that confirms or denies the claim.
  2. If you have a business relationship with Mutares, use your usual contact with them to ask whether your data is involved, instead of relying on the leak-site listing.
  3. Do not download or share files from the leak site.
  4. Check back for updates. This advisory will change if Mutares or an independent outlet publishes details.
