In a statement, Google said a group claiming affiliation with the ransomware gang cl0p was sending emails to “executives at numerous organisations claiming to have stolen sensitive data from their Oracle E-Business Suite”.

Google cautioned that it “does not currently have sufficient evidence to definitively assess the veracity of these claims”.

Messages seeking comment from cl0p and Oracle were not immediately returned.

Google described the email campaign as “high-volume” but declined to share further details.
