What happened

Ally Bank said it found in November 2018 that a third-party supplier had sent files containing personal information to another financial institution by mistake. Ally mailed a notice dated December 12, 2018, and filed a sample with the California Attorney General the next day. Ally did not state how many people were affected.

This was a mistaken transfer, not a hack. According to Ally, the receiving institution reported the error right away and deleted the files. Ally said it had no reason to believe the information was misused, and that the supplier changed its procedures and retrained staff.

What was exposed

The files held what people had provided when they applied for a home loan with Ally. Per the notice, that may include:

  • First and last name, phone number and email address
  • Social Security number and date of birth
  • Credit scores, monthly income, employer name, job title and dates employed

A Social Security number combined with a date of birth and income details is enough for someone to try to open credit in your name or to write a convincing phishing message about your loan.

What Ally offered

Ally paid for two years of Equifax Credit Watch Gold with 3-in-1 monitoring and $1 million of identity fraud expense coverage. Enrollment had to be completed by January 31, 2019.

What to do if you were in it

  1. 1

    Freeze your credit at all three bureaus

    Place a free freeze at Equifax, Experian and TransUnion, separately at each. It blocks most new accounts opened in your name, and you can lift it when you apply for credit yourself.

  2. 2

    Check your credit reports

    Get your free reports at annualcreditreport.com and look for accounts or inquiries you don't recognize. Repeat every few months for a year.

  3. 3

    Be wary of messages about your home loan

    Your lender, income and employer were in the files. Treat unexpected calls, texts or emails about your mortgage as suspect and contact Ally through the number on its website.

  4. 4

    Check whether your email or phone is in this and other breaches
