A search for “allintext:login filetype:log” might reveal exposed credentials in server logs. This Google dork targets files that contain the word “login” and end with a .log extension. These logs often store usernames, passwords, or session tokens in plain text. If you run this query carelessly, you could stumble into someone else’s private data. But used correctly, it helps you audit your own systems for leaks.
Think of it as a security scanner for the open web. You type the dork into Google, and it returns any publicly accessible .log file that includes the word “login”. The results can be shocking—and dangerous if mishandled.
Allintext:login Filetype:log
This specific dork narrows results to log files containing the term “login”. It’s a subset of the broader “filetype:log” search. The “allintext:” operator forces Google to find pages where every word after it appears in the text. So “allintext:login filetype:log” means: show me .log files that have the word “login” somewhere in the file content.
Why does this matter? Because developers sometimes leave debug logs with login attempts on public servers. A single misconfigured web server can expose thousands of credentials.
How To Use This Dork Safely
Follow these steps to check your own domain without breaking laws:
- Open Google in a private browser window.
- Type:
site:yourdomain.com allintext:login filetype:log - Replace “yourdomain.com” with your actual domain.
- Review the results. If any .log files appear, they are publicly accessible.
- Immediately remove or password-protect those files.
Never search for this dork on domains you don’t own. It’s considered unauthorized access in many jurisdictions.
What You Might Find In The Logs
Common entries include:
- Failed login attempts with plaintext passwords
- Session tokens or cookies
- API keys or authentication headers
- IP addresses and timestamps
- Database connection strings
Each of these items is a security risk. A single exposed password can lead to account takeover.
Real World Example
A sysadmin ran this dork on their company’s staging server. They found a file named debug.log with 200+ lines of login credentials. The file was indexed by Google within hours of deployment. They fixed the server config and requested Google to remove the cached version.
How To Protect Your Log Files
Prevent your logs from appearing in search results:
- Store logs outside the web root directory
- Use .htaccess or Nginx rules to deny access to .log files
- Add a
robots.txtrule to disallow all .log extensions - Set file permissions to 600 (owner read/write only)
- Use log rotation and automatic deletion after 30 days
Check your site monthly with the dork to catch new exposures early.
Frequently Asked Questions
Can I Use Allintext:login Filetype:log On Any Website?
Technically yes, but it’s illegal without permission. Only use it on domains you own or have explicit written consent to test.
What If I Find My Credentials In A Log File?
Change those passwords immediately. Then check if the log file is on a server you control. If not, contact the site owner and report the leak.
Does This Dork Work On Bing Or Other Search Engines?
Yes, but syntax varies. Bing uses intext:login filetype:log. Google is the most reliable for this specific dork.
Why Are Log Files Indexed By Google?
Misconfigured servers don’t block search engine crawlers. Googlebot follows links and indexes any file it can access.
How Often Should I Run This Check?
At least once a month. More frequent if you deploy new code or change server configs.
