A common saying around the Linux community is that it is less likely you will get a virus. Some people even claim you can't get any, but I think most Linux users know viruses/malware/nasty stuff do exist for Linux and we need to be security minded just like any other computer user regardless of software running on the machine. One major problem I think some times people forget about is this awesome yet dangerous program called Wine. It is a combatability layer that doesn't have any sandboxing at all. If it works on Windows you just opened yourself up to a much wider variety of issues. The vast majority of desktop users are OSX and Windows users so this can keep us little Linux guys some what safe just because it serves little purpose to target us. As Linux matures on the desktop and gains more adoption I think we need to start taking a look at what this attack vector could mean and how we could help users by limiting exposure.
Here is an interesting Ubuntu forum post I found while researching I thought everyone reading might get a kick out of it and prove some what educational. It is a little old, but still fun. Have a read - http://ubuntuforums.org/showthread.php?t=72598
If you have any ideas how people should protect themselves while still using Wine please comment below, or send me an email.
