On January 5, 2018, Appen informed employees that their personal information could have been compromised in a data breach. The letter states that Appen learned one of their employees had been the victim of a phishing attack on October 16, 2017. Through an investigation of the breach, Appen determined that the attackers could have viewed HR files containing personal information from August 11, 2017 until October 16, 2017. In some cases, the files may have included limited personal information about dependents identified by certain Appen employees hired in 2017, or personal information submitted in 2017 by certain individuals for Appen to run a required background check.
