Customer support company Zendesk revealed on Wednesday that it has become aware of a security incident impacting thousands of accounts activated before November 2016.
Zendesk says its customer support platform is used by 145,000 entities across 160 countries and territories, but the firm claims the 2016 data breach impacted only around 10,000 Support and Chat accounts.
The company learned about the hack recently from a third party. The investigation into the incident is ongoing, but Zendesk has so far determined that roughly 10,000 accounts, including expired trial accounts and inactive accounts, were impacted. The breach does not appear to affect accounts activated after November 1, 2016.
