CrossLinked – LinkedIn Enumeration Tool

LinkedIn enumeration tool to extract valid employee names from an organization through search engine scraping.

---

CrossLinked is a LinkedIn enumeration tool that uses search engine scraping to collect valid employee names from a target organization. This technique provides accurate results without the use of API keys, credentials, or even accessing the site directly. Formats can then be applied in the command line arguments to turn these names into email addresses, domain accounts, and more.

Proxy Support

The latest version of CrossLinked provides proxy support through the Taser library. Users can mask their traffic with a single proxy by adding --proxy 127.0.0.1:8080 to the command line arguments, or use --proxy-file proxies.txt for rotating source addresses.

http/https proxies can be added in IP:PORT notation, while SOCKS requires a socks4:// or socks5:// prefix.
