Accellion Data Breach

On February 1, 2021, the Office of the Washington State Auditor (“SAO”) announced that the personal information of approximately 1.6 million individuals in the State of Washington was compromised in a data security breach of its file transfer software vendor, Accellion. Accellion is a software company that provides hosted file transfer services. Beginning as early as December 2020, and continuing into January 2021, attackers exploited vulnerabilities in Accellion’s file transfer software to gain unauthorized access to files that were being transferred. As a result, an unauthorized individual was able to gain access to data being used by SAO, including the claims information of 1.6 million individuals who filed for unemployment benefits with the State of Washington. The compromised personal information includes names, social security numbers and/or driver’s license or state identification numbers, dates of birth, bank account numbers and bank routing numbers, and places of employment.


On February 2, 2021, Tousley Brain Stephens filed a complaint against Accellion for negligence and violation of the Washington Consumer Protection Act. You can find more information on our Accellion page here.
