Item 1.05 Material Cybersecurity Incidents

On April 24, 2024, Dropbox, Inc. ("Dropbox" or "we") became aware of unauthorized access to the Dropbox Sign (formerly HelloSign) production environment. We immediately activated our cybersecurity incident response process to investigate, contain, and remediate the incident. 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. Based on what we know as of the date of this filing, there is no evidence that the threat actor accessed the contents of users' accounts, such as their agreements or templates, or their payment information. Additionally, 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.

When we became aware of the incident, we launched an investigation with industry-leading forensic investigators to understand what happened and mitigate risks to our users. We have notified and are working with law enforcement. As appropriate, we are also notifying regulatory authorities and users with respect to unauthorized access to personal information.

As of the date of this filing, the incident has not had, and we do not believe it is reasonably likely to have, a material impact on our overall business operations, given our current understanding that this incident is limited to the Dropbox Sign infrastructure. We have not determined that the incident is reasonably likely to materially impact our financial condition or results of operations. We remain subject to various risks due to the incident, including potential litigation, changes in customer behavior, and additional regulatory scrutiny. Our remediation efforts are ongoing.
