amass-enum:tldr:c74a0

The command "amass enum -passive -d ${domain_name}" is used to perform passive enumeration on a specified domain. Here's what each component of the command means:

• "amass": Refers to the amass tool, which is a versatile and powerful open-source network reconnaissance tool.
• "enum": Short for enumeration, which means gathering information about a target (in this case, the specified domain).
• "-passive": This flag instructs amass to use passive enumeration techniques, which means it will gather data from public sources without sending any active network requests or generating any noise.
• "-d ${domain_name}": The "-d" flag indicates that the next argument is the domain name to target, and "${domain_name}" is a placeholder for the actual domain name you want to scan. You need to replace "${domain_name}" with the specific domain you want to enumerate.

In summary, this command instructs the amass tool to passively gather information about a specified domain, without actively interacting with the target's network.
