Which directory search pattern is used to find a directory index that might reveal VPN server keys?

• A. inurl:vpn/keys
• B. intitle:VPN Keys
• C. filetype:pcf
• D. Config intitle:"Index of" intext:vpn

Answer: (D)

This pattern targets finding exposed VPN configuration data by focusing on directory listings that reveal contents. Web servers often display a directory index with a title like “Index of /path” when directory listing is enabled. Using a search operator to require the page title to include that “Index of” phrase pulls up those directory listing pages. Adding the intext:vpn constraint narrows the results to pages that actually mention VPN, making it likely the listing contains VPN-related files. Including the word Config increases the chance that the listing shows a folder or file named Config, which is a common place VPN configuration files (and sometimes keys) reside. Put together, this pattern is effective at uncovering a directory index that might contain VPN config data.

Other patterns are more limited: they either look for specific file types or exact phrases that may not appear on a directory listing, or target URLs that don’t guarantee you’re looking at a directory index.
