Sequoia breach sees hackers access customer Social Security numbers and COVID-19 test results

HR and payroll giant Sequoia has said a data breach has exposed critically sensitive information about its users, including salary and benefits information, SSNs and other government-issued IDs, and even COVID-19 data such as vaccination status.

In a data breach notification (opens in new tab) to the California Attorney General’s office, the company, which has proven popular with SMBs and start-ups, explained: “recently became aware that an unauthorized party may have gained access to a cloud storage system that contains personal information that is processed in connection with the Company’s services to its customers, including your employer or, if you are a dependent, your relative’s employer.”
