Dear all

I once noticed, that my Chromecast created its own wireless-network. The Chromecast wireless-network had minimal security, and it did not require a password to connect to - so everyone could connect to it.

1.
Could a hacker connect to the Chromecasts network, and then upload malware to the Chromecast.
So that when another device connected to the Chromecasts wireless-network, the device would get infected by the malware on the Chromecast?

2.
What changes would it require to the Chromecast device?
Would it require a change in the hardware?
Would it require a change in the firmware?

3.
Does it require NSA-level skills?
Can only be done by Google?
Every tech savy hacker could do it?

4.
Can devices connected to the Chromecasts wireless-network interact with eachother, like on a normal wireless-network?

Thank you

This is probably a Wi-Fi Direct setup for the remote. Generally they don’t give network access to anything connected to them.

Also they would have to be in close enough physical proximity to the device to do it. But most Wi-Fi Direct applications either only accept the remote signals or require some sort of pairing if a phone or other device is being used.

We get the same type of person appearing again and again periodically. They crave attention and who knows what else.
Probably the same users creating accounts that look "ineedhelpplease" as user names stating infections and posting to not respond but create another account. The forum is being flooded with it lately.

They only give access to the Chromecast device, and not network access to eachother like a router?

When I am connected to the Chromecast, then I am paired with it. Or what do you mean?

I know that.
I was just trying to say, that I am not trolling or something like that.
My questions are authentic, and I genuine appreciate when other users reply and help me.
If this is the case, you have sincerest apologies, although do understand the forum gets flooded with "bait" posts all the time, users looking to cause trouble, and a few of yours fit that with what's asked and how.

It’s for communicating directly with the chromecast, either with a remote or a phone so they can talk to each other. It should not be communicating on your lan through the chromecast.

Amazon Fire devices have the same thing, but they hide the SSID. The remotes and apps use almost no airtime, so shouldn’t cause wifi interference.

Maybe I have not been good at explaining the scenario.

The scenario:
There is no other router, network, wifi etc.

The Chromecast creates a wireless network.

There is no password on the Chromecasts wireless network - anyone within range can access it.

Hacker connects to Chromecats wireless network > Hacker infects the Chromecast with malware > device X connects to Chromecast wireless network > the malware on the Chromecast infects device X
Is this possible?
Or is this purely theoretical / NSA-level stuff?

Thank you

It’s probably possible with some zero day flaw, but by design they only respond to known Wi-Fi Direct connections. If you aren’t a sensitive target who someone would go sit outside your home to try to connect to the very short range signal then there isn’t much need to worry.

Your Chromecast can create its own wifi-signal when turned on for the first time or if they don't have a wifi connection. If you see this happening occasionally its very much possible your Wi-Fi network is briefly dropping out. That causes the Chromecast to broadcast its setup network so you can configure a new Wi-Fi network if necessary.
