PowerShell threats surge: 95.4% of analysed scripts were malicious

Symantec is warning of a rise in malicious PowerShell scripts, as attackers increasingly use  the framework’s flexibility to download payloads, traverse through a compromised network and carry out reconnaissance.

Symantec analysed 111 PowerShell malware samples to find out how much of a danger they posed. Of all of the PowerShell scripts analysed by Symantec, 95.4 percent were malicious. “This shows that externally sourced PowerShell scripts are a major threat to enterprises,” the company said.
