Open Source Cybersecurity Tools - Page 4

pyWhat is a Python-based identification tool designed to figure out “what” a piece of text or file content represents, especially in security and OSINT workflows. Given inputs such as hex strings, URLs, email addresses, IP addresses, credit card numbers, cryptocurrency wallets, or entire .pcap capture files, it scans for structured patterns and tells you what it finds. The tool is recursive: it can traverse files and directories to extract meaningful entities, which is useful when analyzing malware samples, network captures, or code repositories at scale. It offers powerful filters called “tags” and distributions that let you narrow results to specific categories like bug bounties, cryptocurrencies, or AWS-related artifacts. For automation and integration, pyWhat provides a CLI with options for rarity filtering, sorting, and JSON export, as well as an API that can be imported into other Python programs.

We all know about the famous spyse.com this python3 scripts scrounges subdomains without the api. There is an option of getting the api, in fact that's what I recommend using the api they provide. Because this methods below may not bring out all subdomains as the api can and perhaps the portability also. https://www.nmmapper.com/sys/tools/subdomainfinder/ https://www.nmmapper.com/kalitools/theharvester/email-harvester-tool/online/ https://www.nmmapper.com/st/networkmapper/nmap/online-port-scanning/
