French govt contractor Atos denies Space Bears ransomware attack claims

Space Bears, a ransomware operation using double‑extortion, claimed on December 28 that it breached Atos and stole a company database to post on its leak site; Atos has publicly denied any compromise of its infrastructure, source code, IP, or proprietary data and says the data originated from unrelated third‑party systems. The report notes Space Bears has been active since April 2024 and added multiple victims to its leak blog, but provides no confirmed evidence of an Atos breach or ransom demand.
