I assume James will just ignore this question, but it never hurts to ask. I can see a lot of people being hacked here on the forum, someone always complains of the BTC stolen.
There is so much virtual currency under your control that highest security standards for you are obviously a must. I have never seeing you talking about your personal setup. Can you share with us how were you able to stay safe all these years. What I mean is you probably using Linux (which of those). You probably have wifi router setup (any special configuration with something enabled or disabled?). VPN? Antiviruses? Any advice would be appreciated.
All your security stands and falls with you. Humans are the weakest part in every security chain. The smarter and more experienced a person is the harder is to hack him. Apart from that there are the same rules as ever:
1. Think before you click (or type).
2. Keep all (!) your systems up-to-date.
3. Install a good antivirus software on the machines you are working with (But it will only sort out 90% of all attacks).
4. Be skeptical about everything and everybody if you can't see the real person (see tip #1).
5. Encrypt everything.
6. Use unique passwords for every website or service which are strong enough (16-32 chars long, letters, symbols and numbers)
7. Backup your most important data frequently and keep the backups offsite (but don't forget #5).
8. Keep a low profile on the internet hoping that no bad guys will spot you.
And if you deal with money or other sensitive information there are a few special recommendations:
- Use multifactor authentification where ever it's possible.
- Use a cold storage which is also placed offsite (bank deposit box, for example)
