If you find this via inurl: search engines (like Shodan, Google, or Bing), it means the camera is publicly accessible and likely streaming live video to anyone with the link.
If you have ever stumbled across the search query "inurl axiscgi mjpg videocgi full," you likely found yourself staring at a grainy, real-time video feed of a random parking lot in Japan, a snowy street in Russia, or a store aisle in the United States.
This specific string of text is a "Google Dork"—a specialized search query used to find specific information that isn't necessarily meant to be public. While it might look like harmless fun to peek into these live feeds, the existence of these open links highlights a massive issue in cybersecurity: the neglect of IoT (Internet of Things) security.
In this post, we will break down what this query actually means, why it works, the security risks involved, and how to protect your own devices from becoming part of the public internet. inurl axiscgi mjpg videocgi full
Using the inurl dork in Google, an attacker can scrape hundreds or thousands of camera IPs. They then:
Modern security best practices require login credentials. However, legacy devices often had "Allow anonymous viewing" enabled by default. If unchecked, anyone can access /axiscgi/mjpg/video.cgi without a password.
Let’s parse this Google (or Bing, Shodan, or Censys) search query piece by piece. If you find this via inurl: search engines
mjpg
Stands for Motion JPEG (M-JPEG). Unlike H.264 or H.265, M-JPEG encodes each video frame as a separate JPEG image. It is less efficient in bandwidth but easier to implement and does not require codec licensing. Cameras that expose an M-JPEG stream without authentication are a goldmine for OSINT investigators.
videocgi
Refers to video.cgi, the script that generates the video feed. In the Axis API, requesting /axis-cgi/mjpg/video.cgi returns a multipart M-JPEG stream. Adding parameters like ?resolution=640x480 or ?fps=5 modifies the output.
full
This is the most interesting part. In many Axis camera firmware versions, the full parameter was used to request the primary, highest-quality stream (as opposed to full vs lowres or medium). Some camera models required ?full to disable cropping or panoramic dewarping. If you have ever stumbled across the search
Thus, a full malicious or investigative request might look like:
http://[camera-ip]/axis-cgi/mjpg/video.cgi?full&resolution=1920x1080
When indexed by search engines (due to misconfiguration or public exposure), the URL appears in results as:
inurl:axiscgi inurl:mjpg inurl:videocgi inurl:full
To understand why this search works, we need to break down the URL components. Most webcams and IP cameras use a standard set of paths to serve video data.
This is often a specific script within the camera's file system (e.g., video.cgi or videocgi) that triggers the camera to start sending the MJPG stream.
When you put it all together, the query is asking Google: "Show me all webpages where the URL contains 'axiscgi', 'mjpg', and 'videocgi'." This almost exclusively returns links to live, unsecured IP camera feeds.
