Take care when dealing with incoming phone calls about fraudulent activity on your credit cards or debit cards - especially if you're asked to call back on a special number. That's the warning issued by Secure Computing. It says that a new VoIP-based phishing scam - using a technique called vishing - is automatically harvesting information about cards.
Vishing is reckoned to let baddies collect details about three-digit security codes, expiration dates and other essential ID information - as well as card and account numbers.
