## PowerShell Execution and Compromise Progression

### Current Status
Following the phishing email detection, unusual PowerShell execution has been observed, signaling the transition from initial access to execution.

### Detailed Findings
- **Execution Method:** PowerShell scripts executed remotely, potentially using the credentials obtained from the phishing attack.
- **Purpose:** The scripts are designed to establish persistence and facilitate lateral movement within the network.
- **Indicators of Compromise:** New registry keys, suspicious network traffic, and unauthorized script execution.

### Mitigation Measures
- **Script Blocking:** Implement strict policies to block or log PowerShell script execution.
- **Credential Management:** Immediate review and rotation of compromised credentials.

### Next Steps
The possibility of persistence mechanisms being established should be investigated, as it may lead to the creation of unauthorized user accounts.
