The company has not released any other information, but there is speculation that the incident may be a ransomware attack.

Foreign media Security Week has checked the websites of several major ransomware gangs, but has not found any organization claiming responsibility for the Sixt attack. Historically, most of the victims listed on these sites did not pay the ransom within the deadline, so Sixt’s name may not appear on these sites until later this month.
