According to the slow fog warning: the Docker Hub database was invaded, involving approximately 190,000 accounts, and related parties in the digital currency field were wary of potential supply chain attack risks. Today Docker officially found the Hub database to be unauthorized access on April 25, 2019. Sensitive data for approximately 190,000 accounts was leaked during the short period of unauthorized access to the Docker Hub database. The data includes usernames and hashed passwords, as well as Github and Bitbucket tokens from Docker autobuild. The authorities quickly took interventions and stated that they would follow up on which Hub accounts were affected and what actions the user should take.
