Chad

Search Google Dorks like Chad. Based on ivan-sincek/nagooglesearch.

Tested on Kali Linux v2024.2 (64-bit).

Made for educational purposes. I hope it will help!

Future plans:

  • Chad Extractor:
    • check if Playwright's Chromium headless browser is installed or not,
    • add option to stop on rate limiting,
    • find a way to bypass the auth. wall for linkedin-user.

How to Install

Install Playwright and Chromium

pip3 install --upgrade playwright

playwright install chromium

Make sure each time you upgrade your Playwright dependency to re-install Chromium; otherwise, you might get an error using the headless browser in Chad Extractor.

Standard Install

pip3 install --upgrade google-chad

Build and Install From the Source

git clone https://github.com/ivan-sincek/chad && cd chad

python3 -m pip install --upgrade build

python3 -m build

python3 -m pip install dist/google_chad-7.0-py3-none-any.whl

Shortest Possible

chad -q 'intitle:"index of /" intext:"parent directory"'

File Download

Did you say Metagoofil?!

mkdir downloads

chad -q "ext:pdf OR ext:docx OR ext:xlsx OR ext:pptx" -s *.example.com -tr 200 -dir downloads

Chad's file download feature is based on Python Requests dependency.

Chad Extractor

Chad Extractor is a powerful tool based on Scrapy's web crawler and Playwright's Chromium headless browser, designed to efficiently scrape web content; unlike Python Requests dependency, which cannot render JavaScript encoded HTML and is easily blocked by anti-bot solutions.

Primarily, Chad Extractor is designed to extract and validate data from Chad results files. However, it can also be used to extract and validate data from plaintext files by using the -pt option.

If the -pt option is used, plaintext files will be treated like server responses, and the extraction logic will be applied, followed by validation. This is also useful if you want to re-test previous Chad Extractor's reports, e.g., by using -res report.json -pt -o retest.json.

Broken Link Hijacking

Prepare the Google Dorks as social_media_dorks.txt file:

intext:"t.me/"
intext:"discord.com/invite/" OR intext:"discord.gg/invite/"
intext:"youtube.com/c/" OR intext:"youtube.com/channel/"
intext:"twitter.com/" OR intext:"x.com/"
intext:"facebook.com/"
intext:"instagram.com/"
intext:"tiktok.com/"
intext:"linkedin.com/in/" OR intext:"linkedin.com/company/"

Prepare the template as social_media_template.json file:

{
   "telegram":{
      "extract":"t\\.me\\/(?:(?!(?:share)(?:(?:\\/|\\?|\\\\|\"|\\<)*$|(?:\\/|\\?|\\\\|\\\"|\\<)[\\s\\S]))[\\w\\d\\.\\_\\-\\+\\@]+)(?<!\\.)",

      "extract_prepend":"https://www.",
      "validate":"<iframe.+?src=\"\\/error\\?src=404.+?\">",
      "validate_cookies":{

      "extract_prepend":"https://www.",
      "extract_append":"/",
      "validate":"Sorry, this page isn't available\\.",
      "validate_browser":true
   },

      }
   },
   "linkedin-user":{
      "extract":"linkedin\\.com\\/in\\/[\\w\\d\\.\\_\\-\\+\\@\\&]+(?<!\\.)",
      "extract_prepend":"https://www.",
      "validate":"An exact match for .+ could not be found\\."
   }
}

Make sure your regular expressions return only one capturing group, e.g., [1, 2, 3, 4]; and not a touple, e.g., [(1, 2), (3, 4)].

Make sure to properly escape regular expression specific symbols in your template file, e.g., make sure to escape dot . as \\., and forward slash / as \\/, etc.

All regular expression searches are case-insensitive.

Web content fetched from the URLs in Chad results files will be matched against all the regular expressions (defined by the extract attributes) in the template file to find as much relevant data as possible.

To extract data without validation, simply omit the validate attributes from the template file as necessary.

Scope Name Type Required Description
extraction extract str yes Regular expression query.
extraction extract_prepend str no String to prepend to all extracted data.
extraction extract_append str no String to append to extracted data.
validation validate str no Regular expression query.
validation validate_browser bool no Whether to use the headless browser or not.
validation validate_browser_wait float no Wait time in seconds before fetching the content from the headless browser's page.
validation validate_headers dict[str,str] no HTTP request headers in key-value format. The Cookie header is ignored.
validation validate_cookies dict[str,str] no HTTP request cookies in key-value format.

Table 1 - Template Attributes

Single Site

chad -q social_media_dorks.txt -s *.example.com -tr 200 -pr 100 -o results.json

chad-extractor -t social_media_template.json -res results.json -o report.json

Multiple Sites

Prepare the domains / subdomains as sites.txt file, the same way you would use them with the site: option in Google:

*.example.com
*.example.com -www

Run:

mkdir chad_results

IFS=$'\n'; count=0; for site in $(cat sites.txt); do count=$((count+1)); echo "#${count} | ${site}"; chad -q social_media_dorks.txt -s "${site}" -tr 200 -pr 100 -o "chad_results/results_${count}.json"; done

chad-extractor -t social_media_template.json -res chad_results -o report.json -v

Analyzing the Report

Manually verify if the broken social media URLs in results[summary][validated] are vulnerable to takeover:

{
   "started_at":"2023-12-23 03:30:10",
   "ended_at":"2023-12-23 04:20:00",
   "summary":{
      "validated":[
         "https://t.me/does_not_exist" // might be vulnerable to takeover
      ],
      "extracted":[
         "https://discord.com/invite/exists",
         "https://t.me/does_not_exist",
         "https://t.me/exists"
      ]
   },
   "failed":{
      "validation":[],
      "extraction":[]
   },
   "full":[
      {
         "url":"https://example.com/about",
         "results":{
            "telegram":[
               "https://t.me/does_not_exist",
               "https://t.me/exists"
            ],
            "discord":[
               "https://discord.com/invite/exists"
            ]
         }
      }
   ]
}

Rate Limiting

Google's cooling-off period can range from a few hours to a whole day.

To avoid hitting Google's rate limits with Chad, increase the minimum and maximum sleep between Google queries and/or pages; or use free or paid proxies. However, free proxies are often blocked and unstable.

To download a list of free proxies, run:

curl -s 'https://proxylist.geonode.com/api/proxy-list?limit=50&page=1&sort_by=lastChecked&sort_type=desc' -H 'Referer: https://proxylist.geonode.com/' | jq -r '.data[] | "\(.protocols[])://\(.ip):\(.port)"' > proxies.txt

If you are using proxies, you might want to increase the request timeout, as responses will need longer time to arrive.

Additionally, to avoid hitting rate limits on platforms like Instagram's while using Chad Extractor, consider decreasing the number of concurrent requests per domain and increasing the sleep and wait times.
