The data breach happened on October 13th, and Dropbox realized the next day that something was wrong. The attacker spoofed the CircleCI integration and delivery platform, which allows login using GitHub credentials, and with a lifelike phishing email, he attacked Dropbox staff. Many of them were blocked by Dropbox’s internal systems, but some passed.

Passwords to malicious sites.
This allowed the attackers to compromise Dropbox’s private Github area and copy 130 code repositories from there. According to a Dropbox statement, the data accessed includes: [It] It also included thousands of names and email addresses belonging to Dropbox employees, current and former customers, sales leads, and vendors. “These repositories contained our own copies of third-party libraries that were slightly modified for use with Dropbox, internal prototypes, and some tools and configuration files used by our security team.” Importantly, it contained no core app or infrastructure code, and access to these repositories is even more restricted and tightly controlled.”
