What happened

The Washington State Auditor's Office used a file-transfer product from Accellion, a roughly 20-year-old tool called FTA, to share files with state agencies. Attackers exploited it, and the office learned on January 12, 2021, after Accellion announced a security problem. It took until early February to learn which files had been accessed. Reports differ on the count: the state described 1.6 million claims involving about 1.4 million people.

The affected people had filed for unemployment benefits between January 1 and December 10, 2020. The auditor held the data while investigating how the state's Employment Security Department lost money to fraudulent claims.

How we research this Report an error

What was exposed

The files contained Social Security numbers, driver's license numbers, bank account numbers and employment information. That mix lets criminals try to open credit, redirect benefits or file false tax returns. Unemployment fraud was already widespread in 2020, so people in this group have extra reason to watch for claims filed in their name.

Who else was in the data

The auditor's office also reported personal information held by the Department of Children, Youth and Families, plus non-personal financial data from about 100 local governments and 25 other state agencies.

What to do if you were in it

  1. 1

    Freeze your credit

    Place a free credit freeze at Equifax, Experian and TransUnion, as the FTC advises when a Social Security number may be exposed. Then check your reports at annualcreditreport.com for accounts you don't recognize.

  2. 2

    Check for unemployment claims you didn't file

    If you get a benefits letter or a tax form for unemployment you never claimed, report it at IdentityTheft.gov and to your state's unemployment agency.

  3. 3

    Watch your bank account

    Bank account numbers were among the data. Check statements for transfers you don't recognize, and ask your bank if you should get a new account number.

  4. 4

    Be wary of messages that mention the breach

    Scammers write to people named in a breach. Don't click links or call numbers in an unexpected email, text or letter; go to the organization's own website or phone number instead.

  5. 5

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