### Overview
The initial access was achieved through a sophisticated phishing attack targeting employees with access to the Ronin Bridge infrastructure. This report delves into the methods used, including the email content and the malicious payload attached.

### Email Content
The phishing email impersonated a known partner organization, urging the recipient to open an attachment containing malicious macros. The subject line read: 'Urgent Security Update Required'.

### Malicious Payload
Once the attachment was opened, it executed a script that established a foothold within the network. The script was designed to deploy further malicious payloads, which we will explore in subsequent reports.

### Recommendations
- Implement advanced email filtering solutions.
- Conduct regular phishing awareness training for all staff.
