Macros in Malware

Malicious scripts embedded in documents to execute unauthorized actions.

Understanding:

Macros in malware refer to malicious scripts embedded within office documents (e.g., Word, Excel) that execute harmful commands when a file is opened. Attackers use macros to deliver payloads, steal information, or establish persistence.

Common Applications and Use Cases:

Used in phishing attacks to trick users into enabling macros.
Often employed in ransomware and spyware campaigns.
Utilized to automate lateral movement within networks.

Best Practices and Security Considerations:

Disable macros by default in enterprise environments.
Use email security filters to detect and block macro-based attachments.
Train employees to recognize suspicious documents and phishing tactics.
