Picus Security: Command Line Interface Among Top 5 Adversarial Techniques

Picus Security's research has identified the Command Line Interface (CLI) as the fifth most prevalent MITRE ATT&CK technique utilized in malware. This finding stems from an extensive analysis of nearly 50,000 malware samples conducted in 2019, which mapped over 445,000 observed adversary tactics, techniques, and procedures (TTPs) to the ATT&CK framework.

The MITRE ATT&CK framework's version 7 consolidated Command Line Interface and Scripting techniques into a single technique, "Command and Scripting Interpreter" (T1059), highlighting its significance. Threat actors commonly leverage operating systems' built-in CLIs for their operations, as these are often less conspicuous than third-party applications.

CLI techniques are considered critical for execution, enabling adversaries to run controlled code and interact with local or remote systems. These techniques are frequently combined with other tactics, such as lateral movement and data exfiltration, to achieve broader attack objectives.

The analysis also detailed sub-techniques within Command and Scripting Interpreter, including PowerShell (T1059.001), AppleScript (T1059.002), and Windows Command Shell (T1059.003). PowerShell, in particular, was noted for its extensive capabilities, making it a favored tool for both administrators and malicious actors.

Picus Security offers insights and potential testing methodologies to help organizations detect and defend against these prevalent adversarial techniques, enhancing overall cybersecurity posture.
