Develop Go Command Line Application for Google Dorking Automation

[husnain-ce]

Objective

Create a Go-based command-line tool to automate Google Dorking inspired by the functionality of the evildork repository. This tool will search Google for specific dork queries and return relevant information.

Requirements

1. Search Queries: Accept dork queries as input.
2. Execution: Perform Google searches using the provided dork queries.
3. Result Handling: Parse and display search results.
4. Error Handling: Implement proper error handling for network requests and search parsing.
5. Rate Limiting: Ensure compliance with Google's TOS by implementing rate limiting.

Detailed Steps

1. Set Up the Project:

   • Initialize a new Go module.
   • Create necessary files and directories.

   mkdir google-dorking
   cd google-dorking
   go mod init google-dorking

2. Install Required Packages:

   • Use goquery for HTML parsing and colly for web scraping.

   go get -u github.com/PuerkitoBio/goquery
   go get -u github.com/gocolly/colly

3. Define Main Function:

   • Create a main function to accept dork queries and initiate the search.

   package main
   
   import (
       "fmt"
       "os"
       "time"
   
       "github.com/gocolly/colly"
   )
   
   func main() {
       if len(os.Args) < 2 {
           fmt.Println("Usage: go run main.go <dork-query>")
           return
       }
   
       dork := os.Args[1]
       fmt.Printf("Executing Google Dork: %s\n", dork)
       results, err := performGoogleDork(dork)
       if err != nil {
           fmt.Printf("Error: %v\n", err)
           return
       }
   
       for _, result := range results {
           fmt.Println(result)
       }
   }

4. Perform Google Dork:

   • Implement the performGoogleDork function to perform Google search and retrieve results.

   package main
   
   import (
       "fmt"
       "github.com/gocolly/colly"
   )
   
   func performGoogleDork(dork string) ([]string, error) {
       var results []string
       c := colly.NewCollector()
   
       c.OnHTML("h3", func(e *colly.HTMLElement) {
           title := e.Text
           link := e.ChildAttr("a", "href")
           if link != "" {
               results = append(results, fmt.Sprintf("%s - %s", title, link))
           }
       })
   
       searchURL := fmt.Sprintf("https://www.google.com/search?q=%s", dork)
       err := c.Visit(searchURL)
       if err != nil {
           return nil, err
       }
   
       // Rate limiting to avoid being blocked by Google
       time.Sleep(2 * time.Second)
   
       return results, nil
   }

5. Error Handling and Rate Limiting:

   • Implement proper error handling and rate limiting to comply with Google’s TOS.

   package main
   
   import (
       "errors"
       "fmt"
       "net/url"
       "time"
   
       "github.com/gocolly/colly"
   )
   
   func performGoogleDork(dork string) ([]string, error) {
       var results []string
       c := colly.NewCollector(
           colly.AllowedDomains("www.google.com", "google.com"),
           colly.UserAgent("Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.124 Safari/537.36"),
       )
   
       c.OnHTML("h3", func(e *colly.HTMLElement) {
           title := e.Text
           link := e.ChildAttr("a", "href")
           parsedURL, err := url.Parse(link)
           if err == nil && parsedURL.Host != "" {
               results = append(results, fmt.Sprintf("%s - %s", title, link))
           }
       })
   
       searchURL := fmt.Sprintf("https://www.google.com/search?q=%s", url.QueryEscape(dork))
       err := c.Visit(searchURL)
       if err != nil {
           return nil, err
       }
   
       // Rate limiting to avoid being blocked by Google
       time.Sleep(5 * time.Second)
   
       if len(results) == 0 {
           return nil, errors.New("no results found or blocked by Google")
       }
   
       return results, nil
   }

6. Run the Application:

   • Build and run the application to perform Google Dorking.

   go run main.go "intitle:\"index of\""

Submission Guidelines

• Push the complete source code in a GitHub repository.
• Include a README file with instructions on how to install and run the application.
