Esri does not offer a free version of ArcGIS 10.6 for general use.

Avoid "cracked" or unofficial download links found on third-party file-sharing sites. These often contain malware or "activation files" (like "AFCore") that can compromise your system's security. Since ArcGIS 10.6 is retired, it no longer receives security patches, making unauthorized versions even more vulnerable to exploits. ArcMap Life Cycle - Esri Support
