content: Docker Hub User Information Breached Email I just received: On Thursday, April 25th, 2019, we discovered unauthorized access to a single Hub database storing a subset of non-financial user data. Upon discovery, we acted quickly to intervene and secure the site.  We want to update you on what we've learned from our ongoing investigation, including which Hub accounts are impacted, and what actions users should take.  Here is what we’ve learned:  During a brief period of unauthorized access to a Docker Hub database, sensitive data from approximately 190,000 accounts may have been exposed (less than 5% of Hub users). Data includes usernames and hashed passwords for a small percentage of these users, as well as Github and Bitbucket tokens for Docker autobuilds.  Change your passwords and tokens.
