Criminals exploit net phone calls

Malicious hackers are turning to net phone systems in a bid to trick people into handing over personal details.

Security firms have identified several scams in which net phone systems are harnessed to try to catch out potential victims.

Anti-virus firm Sophos has also come across a combined e-mail and phone scam aimed at net payments service PayPal which also asks people to phone to update or confirm their account information.

Secure Computing has found a more sophisticated scam that avoids e-mail altogether. Instead the criminals behind this scam have programmed computers to dial a long list of phone numbers and play a recorded message to anyone that answers.

The recorded message warns that a person’s credit card has been used fraudulently and asks them to enter their card number. Significantly, those responding are also asked for the security number found on the rear of the card.
