Red Hand Analyzer 

// BRIEF

Red Hand Analyzer is a free, browser-based tool for analyzing PCAP and NetFlow files. Built for security analysts and incident responders, it detects a wide range of hacker techniques - such as scanning, tunneling, C2 communication, and data exfiltration - using behavior-based analysis rather than traditional signatures. Just upload your capture file to get a clear, easy-to-understand report that highlights suspicious behaviors, vulnerabilities, and notable network events. It’s much easier to use than tools like Wireshark, making it ideal for professionals who need fast insights without deep packet-level expertise. The tool supports files up to 500 MB, with larger limits available on request. It also checks all IPs and domains against threat intelligence feeds to flag known malicious actors. All analysis is done without decrypting payloads, keeping your data private. No software installation or registration is required - just quick, effective forensic analysis in your browser.
