What is PCAP?

PCAP (Packet Capture) data is raw network traffic captured over a network, recording every packet of data transmitted. By providing a detailed snapshot of network activity, PCAP data is invaluable for investigators and analysts to scrutinise communication between devices, track suspicious activity, and uncover hidden connections between targets. 

Packet Capture (PCAP) is a critical tool in network analysis and cybersecurity investigations, offering detailed records of network communications. For law enforcement officials, understanding PCAP is essential for conducting thorough digital investigations, tracing cybercrimes, and gathering forensic evidence. 

In the digital age, organised crime groups increasingly leverage advanced technologies to enhance their operations and evade detection. They use end-to-end encryption to secure communications, posing challenges for law enforcement in intercepting and analysing these messages. However, intelligence agencies can employ strategic techniques like metadata extraction and analysis, known as 'PCAP analysis.' This method involves examining metadata and traffic patterns of IP communications, allowing agencies to gain insights into connections between multiple suspects, their activities and patterns-of-life without decrypting the actual content.
