WebStrike - Network Forensics of Web Shell Upload and Data Exfiltration

Detailed network forensics writeup analyzing a PCAP file to investigate a web shell incident. The analysis successfully identifies the attack's origin (Tianjin, China), the attacker's User-Agent, and the exploitation of a file upload vulnerability to deploy a malicious web shell ('image.jpg.php' in the /reviews/uploads/ directory). Further investigation reveals the attacker's attempt to establish a reverse shell to port 8080 and the subsequent data exfiltration of the sensitive /etc/passwd file.
