Maintenance

grep-backURLs is a web security automation tool to extracts important credentials in bug hunting. It uses subfinder to find subdomains and then those subdomain acts as input links for waybackurls . After that , it uses grep command and keywords.txt to sort out important credentials.

Just beacuse it uses grep command to sort out from waybackURLs link.

Approx 3 hr 48 min 58 sec

Cause I don't want to waste my time to find subdomains and then try each keyword from keyword.txt to check whether is there any credential or not, so decided to automate it.

• Golang

• waybackurls

• subfinder

1. Git clone this URL.
2. Go to grep-backURls directory and give permission to main.go
3. Run command ./main.go
