comment Does a Virtual Machine stop malware from doing harm?
@Basic Very interesting! Could you give a reference for one which does so (e.g. a news article / paper)?

comment Should I format storage after buying it?
So, formatting helps in some cases but definitely not in all. Is that what you're saying? What if I don't expect to be targeted?

So the attack vector might be "sql injection" and the exploit is then the browser? I thought in case of sql injections the exploit would be "unsantized user data" or something like this?

comment Is there any protection against malicious devices on a CAN bus?
I thought an "intermediate device" developed by the car manufacturer could prevent this kind of attack. That means the access to the CAN bus gets controlled by a device between each "foreign" device and the CAN bus. This intermediate device would not do much. It would only check if the device sends its identifier and eventually if it sends too many packages. The intermediate device should have the possibility to cut the access to the CAN bus. Isn't that an efficient way of securing the CAN bus against this simple attack?

comment Is it possible to set up a second router with the same SSID to get the password?
I skipped thorugh some wikipedia articles. It seems as if the router sends a text to the client called "challenge". The client encrypts the challenge with the secret key and a public, symmetric algorithm (AES?). The router compares the encrypted challenge with what it should be. If this is correct, they are connected. My attack does not work as it is hard to get the key given the challenge and the encrypted challenge. Right?
