Recently my debit card information went to another hand, and he/she started to using it until my bank reports that there is an overdraft. I use Ubuntu 14.04 machine.
I am sure I am not a victim of phishing, or email-scam. But I sometime use debit card for online purchases.
Moreover, after going through my account history, I have noticed that these unauthorized transactions occurred just a couple of days after a taxi ride, where I had to pay with my debit card.
And during the same time I just started to explore the Tor network.
I do not have any firewall.
what could be the reason? Any idea?
