(TNS) -- Montgomery County officials reported Tuesday that they estimate it will cost about $280,000 to shore up security.

Last month, Montgomery County had its data encrypted by attackers who demanded 9 bitcoins, an online currency not recognized by any government or bank. The county tried to recover its data, but eventually relented and paid the attackers to prevent them from deleting the data.

The county has already paid about $45,000 for the ransom to get its data back. Lou Ialacci, chief information technology officer for Montgomery, said at a county commission meeting that he is working with experts to put in place new intrusion detection and backup systems.
