The Ubiquity of PowerShell in Cyber Attacks

PowerShell's widespread availability across Windows environments makes it a favored tool among cyber adversaries. Since it is installed by default on most systems, attackers can seamlessly exploit its capabilities without raising suspicion. PowerShell integrates natively with .NET libraries, allowing attackers to execute commands, download additional tools, and move laterally throughout networks. This significant accessibility is a fundamental reason why malicious actors heavily rely on PowerShell in various phases of their attack strategy.
