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

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

In a data breach notice (opens in new tab) to the California attorney general’s office, the company, which has proven popular with SMEs and startups, explained it, “recently became aware that an unauthorized party may have accessed a cloud storage system that contained personal information provided in connection with the Company’s services to its clients, including your employer or, if you are a dependent, your family member’s employer.”
