### Context and Analysis

After detecting a suspicious email attachment, it was identified as a malicious document containing macros designed to execute a remote script. This script aims to install a malicious browser extension, providing attackers with a foothold for further operations.

### Recommendations
- **Immediate Action:** Block and quarantine the email and any similar ones identified in the network.
- **User Awareness:** Conduct an awareness campaign focusing on recognizing phishing emails and suspicious attachments.

### Next Steps
Monitoring network traffic for unusual patterns that may indicate the installation of unauthorized browser extensions.
