Threat actors are creating accounts within the Adobe Cloud suite and sending images and PDFs that appear legitimate to target Office 365 and Gmail users, researchers from Avanan discovered.

Researchers from Avanan, a Check Point company, first discovered the ongoing campaign in December when they stopped one of the attacks, according to a report published Thursday.
