Quiet Leak:
Blue Teaming.

The Quiet Leak is a gripping network forensics challenge that drops participants into the aftermath of a corporate server breach. Analysing a PCAP file uncovers the attacker’s covert actions across SMB, FTP, and a custom TCP heartbeat protocol. Your mission is to retrace their steps and extract a hidden flag. This challenge underscores the need for secure network configurations and sharp forensic skills to detect and understand breaches.
