Data breach

Docker Hub data breach exposes data of 190,000 users.


On April 24, 2019, Docker Hub suffered a data breach that exposed the sensitive data of 190,000 users from the Docker Hub database. The compromised information included usernames and hashed passwords, in addition to Github and Bitbucket tokens for Docker autobuilds.

The aftermath.

Docker Hub requested that all the affected users change their Docker Hub passwords, and the company also urged users to change their passwords for other applications if they used the same password. Docker Hub also revoked the GitHub tokens and access keys of users whose autobuilds were impacted. As a security measure, the company urged its clients to monitor their security logs for any suspicious activity in their environments.

The breach only lasted for a short time, and it affected less than 5% of Docker Hub users. However, these affected autobuilds could serve as an entry point for hackers to gain unauthorized entry into the products which use them. Docker Hub has subsequently taken steps to implement protective measures to enhance its security.

  • Obtaining important forensic information about incidents. The collected logs can be securely archived to help prove adherence to compliance standards and reduce potential legal penalties during investigations.
