- Chmod 777 wallet.dat so that it is world writable.
- Share it over an insecure NFS or SMB share.
- Not use a firewall and park your Linux box inside your Network DMZ while running OpenSSH server.
- Pretend RAID is a backup solution.
- Never back up wallet.dat to a removable device.
- Have a weak root password that is either (1) a dictionary word, or a (2) a dictionary word plus some numbers so that you're vulnerable to a dictionary and rainbow-table attack.
- And of course, you could always run every application as root, including applications that are vulnerable to scripting attacks such as IRC.
- Disable SELinux/AppArmor.
At which point, your Linux box will be almost as insecure as a Windows box and your wallet.dat vulnerable. However, to truly replicate the insecurity you need to run Internet Explorer under Wine running with root privileges and surf the Internet for a while. That would just about do it.
Ok, I guess I'm in a snarky mood today
+1; LMAO that's sounds like alot of work but still will be necessary. This is good to know if any of my professor have more questions about. Some of them question the security about it.
