Atos now says that its systems have not been hit by a ransomware attack after all


  • The threat actor claimed to have breached Atos in late December 2024
  • The company confirmed that the incident involved an “unrelated third party.”
  • Adds that the threat actors have stolen documents “mentioning” the name Atos.

Atos has denied previous claims of a ransomware attack, noting that it was a third party unrelated to the company that was actually breached.

In late December 2024, a ransomware actor named Space Bears added Atos to its data breach website, claiming to have compromised an internal company database. However, the claims were not supported by concrete evidence, as usual items such as ransom demands or data samples were missing.
