Over a hundred of Dropbox source code repos compromised in a phishing attack
Cloud storage service and file synchronization service Dropbox has suffered a data breach after threat actors gained access to 130 of its source code repositories hosted on GitHub. The company said it fell victim to a phishing attack similar to the September GitHub security incident, in which an unauthorized party accessed GitHub accounts by impersonating the code integration and delivery platform CircleCI.
In the Dropbox case, the attackers sent phishing emails to multiple Dropbox employees with a link to a bogus CircleCI login page, which asked victims to provide their GitHub credentials and then use their hardware authentication key to pass a One Time Password (OTP) to the malicious site. The hackers were able to get access to one of accounts and copy 130 of the company’s code repositories, which included copies of third-party libraries modified for use by Dropbox, internal prototypes, and some tools and configuration files used by the security team. Dropbox did not share the number of impacted employees, but said it found no evidence that the intruder gained access to its core infrastructure or its customer data was compromised.
