Malware Leveraging PowerShell Grew 432% in 2017

The total number of PowerShell malware samples observed in 2017 was 432% higher than that in 2016, with 267% of that increase in the fourth quarter, according to McAfee.  Attackers take advantage of PowerShell’s legitimate functionality to carry out malicious activity, such as command and control communications, credential theft, privilege escalation, and to conceal lateral movement on breached networks.  Banks can better protect its systems by ensuring network segmentation is properly implemented and disabling PowerShell throughout the organization.
