• Scripting

Tactic or Technique: Scripting

Attackers use scripting languages like JavaScript, VBScript, and PowerShell to run malicious code delivered through phishing emails or compromised websites. These scripts can load hidden content, redirect you to phishing pages, or silently steal data in the background.
To avoid detection, attackers often scramble the code using encryption, compression, or multiple layers of encoding. This makes it harder for both security tools and analysts to understand what the script is doing.
Scripting is flexible and often used to fingerprint your browser, deliver customized payloads, or create a connection to an attacker-controlled server. Once that connection is active, the script can pull down more malware, collect sensitive information, or give an attacker continued access to your device.
