Zendesk has acknowledged a data blunder that affects 10,000 customers, but only those who used the company's helpdesk solutions prior to 1 November 2016.
The business informed its clients that they had just learned about a security issue that might have affected users of Zendesk Support and Chat products who had their subscriptions authorized before November 1, 2016, as well as those customers.
Regarding the security breach, Zendesk believes that no unauthorized use of stolen login credentials has occurred as of yet.
A "third-party" contacted Zendesk, which led to an internal investigation and the notification of regulatory bodies.
