According to the latest Symantic Security Threat Report criminals are targeting social networking sites as their users are less careful with their personal details making them perfect prey for fraudsters to steal their identities.
In fact according to the report details of some UK bank accounts are available for sale online for as low as a fiver in certain 'cyber crime supermarkets'. Credit card details were also available for as low as 20p per credit card number, whilst full identies were also available. Symantec believe that online identity trading was on the increase and even stolen ebay account information was found to be for sale.
