@mariocataldo In response to consumer feedback, we are waiving fees for removing and placing Security Freezes for the next 30 days. -Tim — Equifax Inc. (@Equifax) September 12, 2017

The oldest credit bureau in the US admitted earlier this month that attackers got into its system and stayed there to access 143 million US citizens' info from mid-May through July 29th. It originally offered free credit monitoring for a year and charged a fee if you wanted to freeze your credit report. Pretty soon, though, those who forked 10 bucks over discovered that the PIN codes they got to lock their accounts were generated using the time and date they made their request. If you bought a PIN on September 11th, 4:20 PM, for instance, your code would have the numbers "0911" and "1620" in it. That method makes the PINs easier to crack.

In addition to making its credit freezes free going forward, Equifax says it will give you a refund if you already paid for a PIN code. However, to be completely sure that nobody opens a credit line in your name, you'll have to pay to freeze your info with Experian and TransUnion, as well. A reader forwarded an email exchange with Equifax to the The New York Times, wherein the credit bureau said it's preparing a service that can lock your Equifax, Experian and TransUnion files at the same time. The company rep told the NYT reader that the service will be available "soon," but it's unclear if it will also be free.
