Malwarebytes: Fileless ransomware an emerging threat for U.S.

A completely fileless ransomware, dubbed Sorebrect, is “one of the first of its kind” to combine traditional ransom functionality with fileless tactics, according to a new Malwarebytes report.

In “Under the Radar: The Future of Undetected Malware,” Malwarebytes detailed four fileless attacks observed throughout 2018, including Emotet, TrickBot, SamSam and Sorebrect. The report referenced a study from the Ponemon Institute, which stated that “fileless malware attacks are estimated to account for 35% of all attacks in 2018, and they’re almost 10 times more likely to succeed than file-based attacks.”
