ffuf:tldr:054b9

This command is using the ffuf tool, a fast web fuzzer, for scanning and discovering subdomains on a website.

Here is a breakdown of the command:

• ffuf: This is the command to execute ffuf.
• -w ${subdomains-txt}: This specifies the wordlist or dictionary file to be used for subdomain brute-forcing. ${subdomains-txt} is a placeholder for the actual filename or the path to the file with a list of subdomains.
• -u ${https:--website-com}: This defines the target URL to be scanned. ${https:--website-com} is a placeholder for the actual URL. Note that the given example assumes the website URL starts with https://.
• -H "${Host: FUZZ-website-com}": This sets a custom header for each request being made during the scanning process. The custom header is Host with the value FUZZ-website-com. ${Host} is a placeholder that will be replaced by ffuf with each entry from the wordlist while fuzzing.

Overall, this command will run ffuf, providing it with a wordlist of subdomains, the target website URL, and a custom header. ffuf will then perform a brute-forcing operation by substituting the FUZZ keyword in the custom header with each entry from the wordlist, effectively trying each subdomain against the target website.
