I want to prevent malicious program accessing my PC via USB. My thread is as follows: I'm just a regular citizen with a non-dangerous job. However I live in a country that didn't care about data privacy and security.
Recently I just learned about the dangers of badusb. The problem is I have never checked the authenticity of my USB although I bought it all from the official stores.
To sort this out, I checked my usb collections with H2Testw. I also had time to download Beamgun app to detect badusb and all the results were positive without any issues. I have also made sure there is no Command Prompt showed on my screen when I plugged the USB.
However, new problem emerged. After I teardown some of my USB, I found a Phison controller inside. I checked on flashboot(.)ru and there is a software that can reflash that controller model.
Does that mean attacker can reflash my USB with a malicious payload?
I wasn't sure if buying from official store and checking with beamgun app and H2testw is enough to prevent badusb. Should I be worried?
What do you think about this?
