ScrewX2 and the Insta360 WiFi security hole.

See also: my previous article.

Over on REDDIT, the subject of the gaping Insta360 WiFi security hole has come up again. User K1N6P1X3l linked to this recent article that summarizes the issue’s history:

Of course, the majority of users simply will not care. “It’s very unlikely to happen to me,” they say. “And if it does, so what, they get my photos.”

In other words, this is just like any other security issue out there. Some folks treat them seriously and take steps to avoid the problems, and others just don’t care. If it were not for the “don’t care” crowd, we wouldn’t have such great malware, viruses and ransomware :)

The exploit allows anyone within WiFi range the ability to connect to your camera and do “stuff.” According to the PetaPixel article, Insta360 has already plugged some of this:

Currently the list_directory has already been terminated and it is no longer possible to access the camera content through the browser.

– Insta360 response, per PetaPixel article

Unfortunately, this is not true. Using the current available firmware, v1.0.59_build1, on my ONE X2 I see it appear on WiFi as expected:

…and if I select this interface, and then open the URL in a browser, I find all my files are indeed able to be listed:

I can then click on one of the .insv video files and play it (or save off a copy):

“And it’s just that easy!”

With this camera, there is no privacy because the camera is broadcasting itself to any WiFi devices around it, and allowing any of them to connect without authentication and then browse and view/download anything on the microSD card.

What’s worse is you can also telnet in to the device. I tried that to see if it still worked:

You will notice it did not ask for a password here, either.

Both of these screenshots (web browser and telnet) were done on my iPad.

WHILE I was connected to my X2 via the iPad, I then connected a Windows PC. Using the default password of “88888888” I was now connected from two devices (which for some reason folks think isn’t possible). Both my Windows PC and my iPad were connected and able to access the files from a web browser.

At least two firmware updates have come out since this first appeared on REDDIT, and it does not appear anything has changed.

ScrewX2: The proof-of-concept that a script kiddie could have written

Shortly after this exploit was first mentioned, someone could have easily created a script that would look for WiFi hotspots following the name “ONE X2 xxxxx” and connect to them. The script could then issue http GET commands to retrieve files on the memory card, or telnet in to delete things, potentially bricking the camera.

Worse, the script could deliver a payload of malware, and if the user ever mounted that memory card in a computer, the malware could have been ran accidentally. Hopefully most of us will never run some random executable or installer found on a camera memory card, but it would be tempting to try to find out what “360VIEWER.EXE” does, or “Insta360MacConverter.dmg” is.

I will not link to any such “screwx2” script, and will delete any links to such posted in the comments here. The cat is firmly out of the bag, with the default WiFi password known, and NO password on the web interface or telnet, so all we can do is hope that Insta360 addresses this issue eventually.
