If you're a Verizon customer, you should change your PIN — now

If you're a Verizon customer, you need to change your PIN — the personal identification number you use when contacting customer service — right now.

An security firm revealed on Wednesday that information on as many as 14 million Verizon accounts was exposed on an unsecured server. The information consisted of the subscriber's name, cellphone number, and the account PIN. The last element is obviously the crucial one: With the PIN, an attacker could easily gain access to the subscriber's account.
