Attackers often exploit system utilities to execute malicious code, using built-in interpreters like PowerShell, Bash, Python, or JavaScript to run arbitrary commands. This tactic, known as MITRE ATT&CK T1059, enables adversaries to conduct reconnaissance, escalate privileges, and move laterally within an environment while camouflaging their activities. Script execution is pervasive in many environments, making it challenging to distinguish between benign activities and potential threats. Attackers leverage command and scripting interpreters to fulfill their objectives, and it's crucial to detect their activities before they establish persistence and seize control. To detect malicious script activity, it's essential to monitor for unusual interpreter usage, suspicious command lines, and process creation with suspicious commands. Additionally, identifying parent-child process relationships for scripts, use of curl or wget for downloads, and execution of scripts from temporary directories can indicate malicious activity. Monitoring for Python script execution, JScript or JavaScript execution, and suspicious VBScript execution can also help identify potential threats. Detecting execution of suspicious batch scripts, unusual interpreter activity in critical directories, and Base64 or obfuscated PowerShell strings can further aid in threat detection. By using these detection methods, security teams can identify and investigate potentially malicious script activities and reduce the risk of attacks.
