Hello, We respect…
We are writing to notify you of a security incident that happened between August 26 and August 31, 2019. We became aware of it on August 31, resolved it immediately, and have been assessing the scope of impact since then. Based on that ongoing assessment, we have concluded that the incident involved your workspace. We are very sorry for any issues this may cause.
Between August 26 and August 31, 2019, an unauthorized party compromised a Segment employee’s account and used it to gain unauthorized access to Segment product usage data. Upon detection, we took immediate action, disabling and deleting the account and removing unauthorized access. We also reported the incident to law enforcement.
What information was involved?
The unauthorized party accessed information about how Segment users interact with the Segment product, as well as first name, last name, email address, and IP address for your Segment users, and the Segment write keys for your workspace. No Segment customer passwords were compromised. No personally identifiable information relating to your own customers was accessed. As a result, no action is required from you at this time.
For more information, please visit our security bulletin page. This page contains a detailed timeline about what happened and information about what actions Segment has taken in response. It will be updated with any new developments.
