PowerShell, a powerful scripting language initially designed for automating Windows administrative tasks, has become a tool of interest for malicious actors due to its flexibility and capability to execute commands without needing to run malware. Organizations are increasingly seeking ways to control PowerShell usage to prevent malicious activities, with some opting to blacklist it entirely while others attempt to allow its use under strict conditions. However, methods like using InstallUtil.exe to bypass controls highlight the challenges of securing PowerShell. The key to effectively detecting malicious PowerShell activities lies in behavioral analysis, which assesses the intent behind the execution of scripts and commands. This approach, employed by CrowdStrike using Indicators of Attack (IOAs), focuses on understanding the context and sequence of actions rather than the specific tools used, providing a proactive defense against the misuse of PowerShell and other legitimate applications for harmful purposes.
