The breach involved a third-party software vendor, Accellion, which the state Auditor’s Office uses to transmit files. The auditor has been looking into how Washington’s Employment Security Department lost hundreds of millions of dollars to fraudsters, including a Nigerian crime ring, who rushed to cash in on sweetened pandemic-related benefits by filing fake unemployment claims in the names of real state residents.
“I know this is one more worry for Washingtonians who have already faced unemployment in a year scarred by both job loss and a pandemic,” Auditor Pat McCarthy said in a news release. “I am sorry to share this news and add to their burdens.”
During a news conference later in the day, she called it “ironic” that files the agency obtained from the Employment Security Department to investigate the fraud would be subject to a breach, possibly opening victims to more fraud.
Those potentially affected include people who filed for unemployment benefits between Jan. 1 and Dec. 10, 2020. That includes many state workers as well as people who had fake unemployment claims submitted on their behalf.
It’s not clear how many people are affected because some would have filed multiple unemployment claims, but McCarthy said she believes it to be at least 1 million people — close to 1 in 7 Washington residents.
The data includes names, Social Security numbers, driver’s license numbers, bank information and place of employment. The Auditor’s Office says it is working with state cybersecurity officials, law enforcement and others to try to mitigate the damage.
Also potentially affected was personal information held by the Department of Children, Youth and Families, and non-personal financial and other data from about 100 local governments and 25 other state agencies.
In a statement Monday, Palo Alto, California-based Accellion called the attack “highly sophisticated” and said it targeted the company’s legacy secure file-transmitting software, a 20-year-old product called FTA. The Auditor’s Office said it had nearly completed transitioning from that product to the company’s new one at the end of the year when the breach occurred; since Dec. 31, the auditor’s office has been on the new system.
Other Accellion customers were also affected, including Australia’s securities regulator and New Zealand’s central bank.
McCarthy said the state learned of the attack Jan. 12, after Accellion made a general announcement regarding a security breach, but Accellion said it notified customers Dec. 23. It wasn’t until last week that the Auditor’s Office learned what files might have been accessed, McCarthy said.
The Auditor’s Office said it has used Accellion for the past 13 years, on a contract worth about $17,000 annually.
