I understand that if someone physically plays with the mouse's firmware memory he can potentially plant malicious code and later seatch for vulnerable places in the machine it is plugged to. Does antivirus and antimalware programs able to detect anything coming from that type of source (mouse). Does that apply only for wireless mouses or also to the cabled ones? Can mouse get infected from a virus/malware without physical intervention, just through infected machine.Have you ever seen anything like this in the wild. How dangerous can it be?

 

Can a laptop charger be programmed somehow as well?

To do what you are suggesting - change the firmware in a mouse - you would need physical access to the computer. No computer can be considered secure if unauthorised persons have physical access to it, and if someone does have access to it there are quicker and simpler ways to steal data or insert malware than by trying to re-program what is probably a PIC type chip in the mouse.

 

A charger takes in mains AC - 110 or 230V - transforms it to about 20V, rectifies it and smooths it to DC and passes it to the battery charging circuitry. There are no programmable components.

 

While being security conscious is good, being paranoid makes life difficult for yourself !

I am going to be away until about the 22nd October. Time on-line will be reduced and my internet access may be limited. PMs may not be replied to as quickly as normal !

Well, they can steal your data, and then fry your laptop to cover their tracks by modifying the charger.

Same principle as USB Killer.

Actually, by modifying and/or adding electronic components, this can be come a motherboard killer, or transmitter.

Chris, yes i understand that, in reality nothing is 100%, even the safety of your own home can be compromised, some of the things i ask are to educate myself and the others around the forum :)

 

Crazy Cat it's good info, it's funny how creative people can get when it comes to destruction!
