### Execution of Malicious Payload
Upon unauthorized access, attackers proceeded to deploy a malicious payload designed to serve as an initial beacon back to their command and control (C2) servers.

#### Key Findings:
- **Payload Type**: Custom malware designed to evade detection by common antivirus solutions.
- **Execution Method**: Utilizes PowerShell scripts embedded within legitimate software updates.
- **Objective**: Ensure continued access and prepare for installation of a more permanent backdoor.

#### Next Steps:
Focus on identifying any backdoor mechanisms being established for persistence in the system.
