Dropbox, the popular file-sharing service, reported a breach affecting its electronic signature service Dropbox Sign, allowing unauthorized access to users’ personal information.

According to the company’s press release, on April 24 hackers accessed users' emails, usernames, phone numbers, and passwords. They also got into some account settings and authentication info, like API keys and OAuth tokens. However, they do not believe the hackers were able to fully access any content or documents in the accounts.

“The actor compromised a service account that was part of Sign’s back-end, which is a type of non-human account used to execute applications and run automated services. As such, this account had privileges to take a variety of actions within Sign’s production environment. The threat actor then used this access to the production environment to access our customer database,” the press release read.
