Unemployment claims information on 1.4 million Washington state residents was exposed via a breach of its file-transfer software vendor Accellion.
The Washington state auditor's office today said names, Social Security numbers, banking information, and other personal data on residents filing unemployment claims were breached in the attack on the vendor, whose product is used by the auditor's office for transferring large files. The exposed data affects claimants who filed for unemployment benefits with the state between Jan. 1 to Dec. 10, 2020.
Meanwhile, an Accellion executive told The Seattle Times that the breached software was FTA, an older legacy package that the company has urged customers for years to abandon in favor of a next-generation product. Accellion's software was breached in December.
