What is Script-Based Malware?
Script-based malware refers to malicious software that utilizes scripting languages to execute harmful actions on a victim's system. This type of malware often employs languages such as JavaScript, Python, or PowerShell to create and execute payloads that can compromise systems, steal data, or facilitate unauthorized access.
Common Features
- Lightweight: Script-based malware is typically less resource-intensive than traditional executable malware.
- Cross-Platform: It can run on various operating systems, making it versatile in its attack methods.
- Obfuscation: Many script-based malware variants employ obfuscation techniques to evade detection by antivirus software.
How It Works
Script-based malware can be delivered through various channels, including phishing emails, infected websites, or malicious downloads. Once executed, the script may perform a range of actions, such as downloading additional malware, exfiltrating sensitive information, or manipulating system settings.
Impact on Incident Response
During incident response, the identification and analysis of script-based malware can be challenging due to its flexibility and ability to blend in with legitimate scripts. Effective incident response requires teams to analyze scripts thoroughly and employ specialized tools to detect and mitigate these risks. Implementing robust security measures, such as regular updates and awareness training, can help organizations defend against script-based threats.
