1. Native to Windows: PowerShell is a scripting language and automation framework built into the Windows operating system. Since it's a native tool, it doesn't raise suspicions like downloading or running external malicious software might.
2. Powerful Capabilities: PowerShell is mighty and versatile. Attackers can use it to execute a wide range of tasks, from simple commands to complex scripts, making it an attractive choice for carrying out malicious activities.
3. Script Obfuscation: Attackers can obfuscate their PowerShell scripts to make them more difficult to detect by antivirus software and security tools. This means they can hide their intentions more effectively.
4. Living Off the Land (LOLBin): PowerShell is considered a "living off the land" tool, which means it uses legitimate, built-in features and processes. Attackers take advantage of this to avoid detection, as they are essentially using trusted tools for nefarious purposes.
5. Bypassing Application Whitelisting: PowerShell can often bypass application whitelisting, a security measure that allows only approved applications to run on a system. Attackers can exploit PowerShell to run scripts even if other software is restricted.
6. Remote Execution: PowerShell can be used to run commands remotely, making it a valuable tool for attackers who want to gain control of remote systems and exfiltrate data.
7. Persistence: Attackers can use PowerShell to establish persistence on compromised systems, ensuring their access remains even after a reboot. They can set up scheduled tasks or create malicious services using PowerShell.
8. Ease of Learning: PowerShell is relatively easy to learn, which means a broader pool of potential attackers can quickly pick up the language and use it effectively.
9. No Files on Disk: PowerShell commands and scripts can be executed directly in memory, without creating suspicious files on disk. This makes it challenging for traditional antivirus software to detect and block malicious activity.
10. Community Support: There are numerous resources and forums where attackers can find pre-built PowerShell scripts and techniques, enabling them to access a wealth of knowledge and tools for malicious purposes.
Overall, PowerShell's ubiquity and its ability to perform both legitimate and malicious tasks make it an attractive choice for cybercriminals. As a result, organizations need to implement robust security measures, monitor PowerShell usage, and educate their teams to defend against these types of attacks.
