Michelin confirmed it was impacted by the Oracle E-Business Suite (EBS) hacking campaign, which SecurityWeek reports was claimed by Cl0p and involved exploitation of an Oracle EBS zero-day. Michelin stated that hackers accessed some files, but said only a small, localized volume of data was affected and it contained no sensitive or technical IT information; the company also said there was no ransomware and no impact on its global systems, and that corrective actions were effective. SecurityWeek reported the cybercriminals publicly released more than 315GB of archives allegedly stolen from Michelin, with a file-tree review indicating at least some data originated from an Oracle EBS environment.
