### Analysis of Initial Access Vector

Following the detection of a suspicious phishing email targeting Israeli entities, further investigation has revealed that the email contained a malicious attachment designed to bypass standard security protocols. The attachment exploits a known vulnerability in outdated email clients, delivering a payload that establishes an initial foothold for the Agrius APT.

#### Key Findings:
- **Email Source:** Traced back to a compromised server in Eastern Europe.
- **Payload Analysis:** The attachment is a macro-enabled document that, when opened, executes a PowerShell script to download additional malware components.

#### Recommendations:
- Update email client software to mitigate vulnerabilities.
- Implement stricter email filtering to detect similar threats.
