Systems and methods for ransomware protection in collaboration systems. One embodiment operates in conjunction with a collaboration system that manages one or more user devices that store device-local copies of content objects in storage areas of the one or more user devices. The collaboration system is accessed by the one or more user devices to facilitate collaboration activity over the content objects. Patterns of collaboration activity are classified, and in some cases, such patterns are deemed to be indicative of ransomware. If ransomware is indicated to be running on a user device, the collaboration system is notified that a ransomware process has been detected on the user device. The collaboration system delivers a prevention policy to other user devices that interface with the collaboration system. The prevention policy is in turn enforced by the other user devices to prevent synchronization of content object changes made by the ransomware.

Ransomware remediation in collaboration environments

Executable code comprising a local file system is stored at a collaboration system server for downloading. The remote collaboration system responds to a message from a user device to download the local file system. The local file system to be downloaded is configured to operate on the user device so as to issue requests from the user device to perform an initial access to server-side collaboration data. The collaboration system responds to such requests by predicting interests of the user, which predictions are used to retrieve additional server-side collaboration data. The additional server-side collaboration data is sent to the user device and stored on the user device in an area for locally-stored collaboration system information. The user provides search terms for searching the locally-stored collaboration system information, and results are displayed on the user device. The results are displayed without the need to perform additional communications with remote collaboration system.

User device processing of information from a network-accessible collaboration system

Content management in a collaboration system. Ease-of-use of shared content is facilitated. A URL is presented in a user interface. The system determines (e.g., based on user preferences) whether to display the content corresponding to the URL in a browser at the user device, or whether to display the content corresponding to the URL using a non-browser application. If the user device is configured to display the content corresponding to the URL using a non-browser application, then when the user clicks or touches or hovers, or otherwise indicates a selection of a URL, the system displays the content using the non-browser application. In this situation, the system retrieves the content from the collaboration system, stores a local instance of the content in local storage of the user device, and opens the local instance using the non-browser application. Local instance edits are synchronized with the collaboration system using a synchronization protocol.

Synchronized content replication

Methods, systems and computer program products for managing shared content directory structure metadata stored on client devices. A method embodiment includes identifying a collaboration system that stores one or more content objects that are organized in accordance with a directory structure. Requests pertaining to the content objects are raised by processing entities running on the client device. The requests include instructions to retrieve one or more of multiple types of metadata associated with the directory elements that constitute the directory structure. Based on timing and patterns of requests pertaining to the content objects, a monitoring function detects unwanted runaway retrieval by a runaway process. To prevent further unwanted runaway retrieval of the metadata, the runaway process is blocked from continuing its pattern of unwanted (runaway) retrieval. The collaboration system is notified of characteristics of the runaway process. Some or all of the unwanted retrievals are remediated automatically.
