Sublist3r is a popular open-source tool used in cybersecurity and penetration testing. It’s designed to enumerate subdomains of websites using various techniques.
Here’s a brief overview:
- Purpose: Sublist3r helps security professionals and ethical hackers discover subdomains associated with a target domain.
- Functionality: It uses search engines, DNS records, and other sources to find and list subdomains.
- Key features:
- Multithreaded subdomain enumeration
- Supports multiple search engines
- Can use Netcraft, Virustotal, ThreatCrowd, DNSdumpster, and ReverseDNS
- Usage: Typically used in the reconnaissance phase of security assessments or penetration tests.
- Language: Written in Python
- Availability: Open-source and freely available on GitHub
We can perform these :
Key Options:
- -d: Specify the target domain
- -t: Number of threads (default is 40)
- -o: Save results to a text file
- -v: Verbose mode
- -p: Scan specific ports
- -e: Specify search engines to use
- Specify the domain: -d <url>
Command: ./sublist3r.py -d google.com
- Specify the search engine: -e <engine name>
Command: ./sublist3r.py -d google.com -e bing
- Specify the port : -p <port number>
This way, we can use sublist3r and enumerate subdomains.
