OLYMPIA, WA — The Washington State Auditor's Office (SAO) says it will begin notifying everyone whose data was compromised by their recent security breach sometime this week.

Notifications will be sent out over email and will include an offer of 12 months of free credit monitoring, plus instructions on how to receive further assistance, if necessary. The SAO says it intends to have notified all potential victims by the end of the next two weeks.

The data breach, which was first reported earlier this month, involved hackers accessing SAO data through Accellion, a third-party provider the office had been using to transfer files.

At the time, the SAO had been auditing the Employment Security Department's handling of an unrelated unemployment security issue, meaning hackers could have accessed the data of all 1.6 million Washingtonians who applied for unemployment last year. The breach may also have included other Washington residents whose data was being reviewed by the SAO as part of other investigations.

The exposed data likely includes the claimant's name, social security number, driver's license or state identification number, workplace, and bank account or bank routing numbers.

In the weeks since the hack was discovered, the auditor's office says they have taken steps to address their online security, and are still working with Accellion to identify the exact files that the hackers may have accessed.

The SAO has also set up a web portal containing legal information and resources, frequently asked questions and general tips to protect yourself if you are concerned your data was compromised.
