The Netherlands-based Russian search engine, email service provider and ride-sharing trips Yandex has revealed a data breach that led to 4,887 email accounts of its users being hacked.
The company blamed the incident on an unnamed employee who was providing unauthorized access to users’ mail for personal gain. “The employee was one of three system administrators with the necessary access rights to provide technical support for the service,” Yandex said in a statement.
The company stated that the security breach was identified during a routine audit of its systems by its security team, and there is no evidence that the user’s payment details were compromised during the incident, and it informed the affected mail owners to change the passwords.
It is not immediately clear when the violation occurred or when the employee began providing unauthorized access to outside parties. Yandex said: We are conducting a comprehensive internal investigation into the incident, and are also making changes to administrative access procedures, and this helps reduce the possibility of individuals compromising the security of user data in the future.
It is noteworthy that this is not the first time that technology companies are plagued by internal threats that lead to financial damage.
