Hello guys,

I will tell the story how I lost 0.4 BTC. I want to ask you advices.

It is (was) a paper wallet I generated in bitaddress.org. I generated it online, in my work. The system is protected by firewall and VPN. Then I printed it in the printer connected in the network.
The network is very safe - I will not tell the name of company for privacy. The printer is connected to the system's network.
Supposing that there's no one from inside evolved, is it possible to have a malicious intermediate between my computer and bitaddress?
Any other ideas about how that happened?

Another thing is your opinion about one method I'm thinking for generate a paper wallet in bitaddress.org. Everybody tells that the bitaddress' website is safe. Is that so?
The idea is to enter in the website and switch off the internet. The next steps will all be done without any internet:
- generate the wallets
- restore the windows, erasing everything
- take out this HD, connect to my other notebook and format it using the program Eraser, which records random information in the drive
- return the HD to the previous notebook and install Windows again
Only now, turn on the internet.

Any risk in this procedure?

Thank you.
