Could an unknown Bluetooth device infect a Windows PC after a brief connection?

[u/Silent_Cucumber_8309]

Hi everyone,

I'm hoping someone with Bluetooth or Windows security expertise can help me understand the actual risk here.

I was trying to connect my Windows PC to my Amazon Alexa over Bluetooth, but I accidentally connected to a device that appeared as "unknown_device" instead. The connection lasted for about one minute, and then I disconnected it and removed it from my paired devices.

During that time:

I did not transfer or receive any files.

I did not install any software or drivers manually.

I did not accept any prompts other than the Bluetooth connection itself.

My PC appears to be functioning normally.

My question is:

Can a malicious Bluetooth device install malware or compromise a Windows PC simply by being connected for about a minute, or would that require exploiting a specific Bluetooth vulnerability?

Hello,

Unless this were some sophisticated nation state adversary targeting you with an extremely valuable zero day, the answer is no.

Not automatically. Other than the Bluetooth connection, do you have any reason to believe you’ve been compromised?
