Tampered Chef Malware Hidden in Productivity Apps

A malware cluster consisting of trojanized productivity applications masquerading as legitimate business tools such as PDF editors and calendars. The software may remain dormant for weeks or months, then connect to an upstream API to download additional malicious modules, including info-stealers or remote access trojans, and can execute arbitrary code on victim machines.
