PCAPdroid - network monitor

PCAPdroid is a mobile application that allows users to capture and analyze network traffic without the need for root access. Unlike other VPN services, PCAPdroid does not rely on a remote server, but instead processes all data locally on the device. This makes it a convenient and secure option for users who want to monitor their network activity. One of the key features of PCAPdroid is its ability to log and examine connections made by both user and system apps. This allows users to gain a better understanding of their device's network usage and identify any potential security threats. The app also provides detailed information such as the Server Name Indication (SNI), DNS query, HTTP URL, and remote IP address for each connection. In addition to logging and examining connections, PCAPdroid also offers built-in decoders that allow users to inspect HTTP requests and replies. This feature is particularly useful for those who want to analyze the content of their network traffic. Users can also view the full connection payload in hexdump or text format and export it for further analysis. For those who need to decrypt HTTPS/TLS traffic, PCAPdroid offers the option to export the SSLKEYLOGFILE. This allows users to view the encrypted data in plain text, providing valuable insights into their network activity. The app also allows users to dump the traffic to a PCAP file, download it from a browser, or stream it to a remote receiver for real-time analysis using tools like Wireshark. PCAPdroid also offers advanced features for paid users, including a firewall that allows them to create rules to block individual apps, domains, and IP addresses. This can help users protect their device from potential threats and unwanted network activity. The app also offers malware detection by using third-party blacklists to identify and block malicious connections. To make the analysis process easier, PCAPdroid allows users to create rules to filter out the good traffic and easily spot anomalies. It also provides offline database lookups to identify the country and Autonomous System Number (ASN) of remote servers. For rooted devices, PCAPdroid can capture traffic even while other VPN apps are running. For those interested in using PCAPdroid for packet analysis, the app offers a specific section in the manual to guide users through the process. Additionally, users can join the PCAPdroid community on Telegram to discuss the app and receive updates on the latest features. With its comprehensive features and user-friendly interface, PCAPdroid is a valuable tool for anyone looking to monitor and analyze their network traffic.
