Security News > 2023 > October > BYOD should stand for bring your own disaster, according to Microsoft ransomware data

Microsoft research says that 80-90 percent of ransomware attacks over the past year originated from unmanaged devices.

The threat BYOD presents is compounded by the steep rise in overall ransomware incidents this year; Microsoft says human-operated ransomware attacks are up by more than 200 percent since September 2022.

Human-operated ransomware attacks refer to what many people would consider the "Normal" type of ransomware - cybercriminals use manual, sophisticated techniques to break into an organization, elevate their privileges, and launch an attack from the inside.

Organizations will welcome the news from Microsoft that of these vastly increased ransomware attack attempts between July 2022 and June 2023, the period in which Microsoft's data was pulled, the success of these is low.

Just 2 percent of human-operated attack attempts led to the deployment of ransomware against victims, Microsoft says, adding that strong security policies in organizations offer a highly effective defensive capability to modern ransomware attacks.

"On average 60 percent of human-operated ransomware attacks used remote encryption over the past year. This is a sign of attackers evolving to further minimize their footprint." .
