Dropbox offers a handful of features that use machine learning to understand content much like a human would. For example, Dropbox can generate summaries and answer questions about files when those files are previewed on the web. Instead of asking a coworker for the gist of last week’s all-hands meetings, Dropbox can provide a summary of the video and a user can ask questions about its contents—all from the file preview. We recently expanded AI-powered summarization and Q&A to handle multiple files simultaneously, too.  (As part of our commitment to responsibly using AI, Dropbox abi ..read more

The Dropbox API servers will be updated with certificates issued from a new root starting on or after January 1, 2026. Some of the official Dropbox SDKs implemented certificate pinning based on a list of root certificates included in the SDKs. These certificates will stop working in many web browsers and devices in 2026, so Dropbox needs to change which root is used to issue its server certificates. Apps using these SDKs need to be updated to the latest versions of the Dropbox SDKs to ensure uninterrupted access to the API. The versions listed below have been updated to maintain compatibility ..read more

People trust Dropbox to keep their most important content secure. As more teams embrace remote and distributed work, ensuring the privacy and security of their data has never been more important. While customers already appreciate our simple, seamless access controls, those who work with more sensitive information have told us they want even more control over how their data is secured. One of the ways that Dropbox is meeting the needs of these customers is with the introduction of zero-knowledge, end-to-end encryption for team folders. While Dropbox already encrypts files at rest using 256-b ..read more

We recently discovered a new training data extraction vulnerability involving OpenAI’s chat completion models (including GPT-3.5 and GPT-4). This work builds upon prior Dropbox LLM prompt injection research as well as that of academic researchers. Our findings were shared with OpenAI in January 2024, confirmed as vulnerabilities, and subsequently patched. AI/ML security practitioners should take note as the attacks are transferrable to other third-party and open-source models. Background As part of our mission to help Dropbox customers work smarter and more effectively, Dropbox contin ..read more

A Dropbox team can contain multiple members, and each member may have many of their own files and folders, as well as access to other files and folders, such as via shared folders or team folders. That can add up to a lot of content, and sometimes, it‘s useful to be able to programmatically list all of those items across all of the members of the team, such as for organizational or auditing purposes. The Dropbox API does offer the ability to list the contents of any particular folder, and there are multiple ways an app could go about finding and listing all of the contents across all team me ..read more
