### Overview
The initial access vector was identified as a spear phishing email targeting key personnel within the organization. The email contained a seemingly legitimate attachment that, once opened, executed a hidden script.

### Analysis
- **Sender:** The email originated from a spoofed address resembling a trusted partner.
- **Content:** The attachment was a weaponized document with macros that, when enabled, triggered the download of a malicious payload.

### Next Steps
