ShrewdEye.app is a valuable resource for ethical hackers and penetration testers, providing a massive collection of domains to kickstart reconnaissance. Instead of manually running multiple DNS enumeration tools, ShrewdEye offers pre-compiled domain lists for quick analysis.
Key Features:
- Pre-enumerated Domains: Access extensive DNS records for popular targets.
- Downloadable Lists: Obtain full or validated resource lists in `.txt` format.
- Easy URL Format: Simply modify the URL to search for any domain:
https://shrewdeye.app/domain/<target-domain>
Example for `booking.com`:
- Full resources: 1566 entries
- Validated resources: 676 entries
You Should Know: Practical Enumeration Techniques
1. DNS Enumeration with Dig
Extract DNS records for a target:
dig booking.com ANY +noall +answer
2. Subdomain Bruteforcing with Sublist3r
sublist3r -d booking.com -o subdomains.txt
3. MassDNS for Large-Scale Resolution
Filter live subdomains from ShrewdEye’s list:
massdns -r resolvers.txt -t A -o S -w live_domains.txt booking.com.txt
4. HTTP Probing with httpx
Check active web services:
cat live_domains.txt | httpx -title -status-code -o results.html
5. Wayback Machine for Historical Data
waybackurls booking.com | tee urls_archive.txt
6. Nmap for Service Detection
nmap -sV --script=http-title -iL live_domains.txt -oA nmap_scan
What Undercode Say
ShrewdEye.app accelerates reconnaissance by aggregating DNS data, but always:
– Verify results (false positives exist).
– Combine with active scanning (Nmap/httpx).
– Respect legal boundaries—unauthorized testing is illegal.
For deeper analysis:
- DNSRecon:
dnsrecon -d booking.com -t axfr,std
- Amass for Passive Mapping:
amass enum -passive -d booking.com -o amass_results.txt
- FFuF for Directory Bruteforcing:
ffuf -w ShrewdEye_list.txt -u https://booking.com/FUZZ
Expected Output:
A structured workflow:
1. Gather domains (ShrewdEye).
2. Filter live hosts (MassDNS/httpx).
3. Scan services (Nmap).
4. Archive historical data (WaybackMachine).

Note: Always obtain proper authorization before testing. Unethical hacking carries severe penalties.
