AOL today issued a security warning to its users not to divulge credit card details over the internet.

The US internet service provider discovered its users had received hoax emails requesting users resend credit card details due "technical difficulties."

"AOL staff will never ask for a password or customers' [bank] details. If any members do receive this email then it is definitely a scam and they should just ignore it," said a company spokesperson.

Although the company estimated only two members a month fall for the scam the hoaxes are still worrying.

AOL's investigation team is employed to search for such scams but prosecutions are few and far between.

"Security is a big issue for users and anything that poses a threat to that should be taken extremely seriously and dealt with immediately," says the company.
