Dropbox disclosed a security breach after threat actors stole 130 code repositories after gaining access to one of its GitHub accounts using employee credentials stolen in a phishing attack.
"To date, our investigation has found that the code accessed by this threat actor contained some credentials-primarily, API keys-used by Dropbox developers," Dropbox revealed on Tuesday.
The successful breach resulted from a phishing attack that targeted multiple Dropbox employees using emails impersonating the CircleCI continuous integration and delivery platform and redirecting them to a phishing landing page where they were asked to enter their GitHub username and password.
After stealing the Dropboxers' credentials, the attackers gained access to one of Dropbox's GitHub organizations and stole 130 of its code repositories.
"These repositories included our own copies of third-party libraries slightly modified for use by Dropbox, internal prototypes, and some tools and configuration files used by the security team," the company added.
"While GitHub itself was not affected, the campaign has impacted many victim organizations," GitHub said in an advisory at the time.
