OLYMPIA, Wash. – Investigators now say the breach of a state database exposed the personal data of hundreds of thousands of Washingtonians in late January.

Personal data in active, expired, revoked or suspended licenses was stolen by the hackers from the Washington State Department of Licensing.

Investigators say up to 650,000 current and former Washington state professionals and business owners may have had sensitive data like Social Security numbers stolen.

The breach was detected January 24th and disclosed last week.

The agency is currently reaching out to those who may have been affected and offering free credit monitoring and identity theft protection.
