> On April 24, 2024, Dropbox, Inc. (“Dropbox” or “we”) became aware of unauthorized access to the Dropbox Sign (formerly HelloSign) production environment. [...] Upon further investigation, we discovered that the threat actor had accessed data related to all users of Dropbox Sign, such as emails and usernames, in addition to general account settings. For subsets of users, the threat actor also accessed phone numbers, hashed passwords, and certain authentication information such as API keys, OAuth tokens, and multi-factor authentication. [..] we believe this incident was limited to Dropbox Sign infrastructure and there is no evidence that the threat actor accessed the production environments of other Dropbox products. We are continuing our investigation. Oompf.
