I rec’d a call from Citibank 1 day after I bought 2 tickets from Cebu Airways through the net, telling me that my card has been copied and a transaction in US$ was pending for authorisation. Luckily, the bank called me to verify before they approved the transaction, which was rejected of course. Applause to them for their alertness and efficiency. Wonder how all these people are able to copy your card, when there is a security lock.
Do you think it is safe to make a purchase through the net?
I would run Malwarebytes and superantispyware to see if you got some infections. There are malware that can log your keystrokes as you type in your credit card details for instance Zbot which is a notorious trojan that aim at unsuspecting users. Malware today is much more sophisicated than 2 years ago, and some can give no signs at all that your computer is affected.
If you use a wireless router, you need to secure that, and you need to have a firewall and security protection. It is safe if you know what to do and I do buy through the net myself.
