You are a security analyst investigating suspicious activity on your network. Multiple systems have reported anomalies, and you need to analyze system logs, security logs, and firewall logs to determine: 1. **What type of attack occurred?** 2. **Which user account was compromised?** 3. **What was the attack vector (initial access method)?** 4. **Which system was Patient Zero?** 5. **What remediation steps should be taken?** Your organization uses Windows servers with standard logging enabled. The Security Operations Center (SOC) has collected logs from multiple sources spanning a 24-hour period. Analyze the logs carefully to identify the attack timeline, tactics, and indicators of compromise (IOCs).
Instructions: Review all log entries from different systems and sources. Answer each question based on your forensic analysis of the logs. Pay attention to timestamps, user accounts, source IPs, and process behaviors.
