In the recent weeks, they have been hacking dozens of the telephone systems across the whole country, by using them a way to contact the unsuspecting customers of the bank and then by tricking them into divulging the customer's bank account numbers and the passwords too.

The victims of this trick are typically the banks with some smaller regional institutions, which usually have fewer resources for scam detection. Scammers hack into the phone systems and then they call the victims, by playing the pre-recorded messages, which says that there occurred some billing error or by warning them that their bank accounts have been suspended due to some suspicious activity. If any of the worried customers enters the account number and also the ATM password, those bad guys can use the customer's information to make the fake debit cards and then they empty the bank accounts of their victims.

Hackers have made headlines for the purpose of breaking into the phone company systems approximately more than twenty years ago, and this practice was known as phreaking, but as soon as the traditional telephone system are becoming more integrated with Internet, it is now creating new opportunities for such frauds that are just beginning to be understood.
