Home Computer Audio Asylum

Music servers and other computer based digital audio technologies.

RE: I disagree with you and agree with Sprezza Tura

The main take-home is that these cards can hold hidden information that can not be discovered by the user using only normal access to their pins. This means:

1. If they contain illicit material or malware, they may retain this unwanted information after you think you have "sterilized" the card. This information may remain accessible to anyone who knows a secret code, but otherwise inaccessible by a normal user.

2. This capability makes it easier for the card to serve as a vector for malware or spy ware, etc...

3. If you do not trust the supply chain for the card or if the card has ever been connected to an untrusted computer then it is not to be trusted, and should not be connected to any computer that you wish to continue to trust.

Of course, this depends on how paranoid you are, what information you have and who might want to know it, if you are a person of interest, etc... Probably not a problem for cards used in computers that are never used for anything but audio, but if you have a file server that holds personal material as well as music then there may be a risk.
