This is a Google search operator that restricts results to pages where the following text appears inside the URL itself. It is a powerful tool for finding specific directories, file types, or parameter structures on web servers.
This is a classic example of (or Dorking), where attackers use advanced search operators to find vulnerable IoT devices [1, 2]. For many of these results, the cameras are accessible simply because: Default passwords were never changed. The web interface is indexed by search engines. Firmware hasn't been updated to fix known exploits. inurl indexframe shtml axis video server top
Sometimes, the top parameter reveals not the video but system status pages showing: This is a Google search operator that restricts
That specific search query— inurl:indexframe.shtml axis video server —is what's known as a . It’s used to find publicly accessible Axis communications security cameras and video servers that are connected to the internet [1, 2]. For many of these results, the cameras are
The search query inurl:indexframe.shtml axis video server top serves as a stark reminder of the enduring legacy of insecure IoT and networked surveillance devices. What was once a convenience for system administrators—a simple web interface to check video feeds—has become a treasure map for cybercriminals and voyeurs.
If the video server is misconfigured (e.g., allowing HTTP instead of HTTPS), credentials sent during login can be intercepted via man-in-the-middle attacks. Even the presence of a login page tells an attacker that the system exists, and they can attempt brute-force or password spraying attacks.
Instead of relying on indexframe.shtml , use:
