A system performs federated learning and retraining of a machine learning model used for processing audio detected by a user device. The system uses both gradient data (which may correspond to false-rejects) and audio data (which may correspond to false-positives) received from devices. The system may also use a teacher model to produce labels for data in an automated fashion, thus allowing retraining to happen in an unsupervised manner.

Federated learning for audio processing

The disclosed computer-implemented methods for automatically recovering from malware attacks may include (1) saving, in response to determining that a reputation of a process is unknown, a backup copy of a file on a remote storage device prior to allowing the process to modify the file; (2) determining, after the process has modified the file, that the process is potentially malicious; and (3) restoring, in response to determining that the process is potentially malicious, the backup copy of the file from the remote storage device. The provided methods may automatically recover computers from ransomware attacks and other malware attacks which encrypt file systems. Various other methods, systems, and computer-readable media are also disclosed.

Purchasing related activity that is executed on computing devices on a LAN is monitored. Information is identified concerning purchases of IoT devices on the LAN, based on the monitoring of the purchasing related activity. For example, a specific purchase of a specific device (or specific device type) can be identified, or identifying information concerning a purchased device can be inferred, based on monitored purchasing related activity. IoT devices are discovered on the LAN and identified. Identifying a discovered device can further comprise interrogating the discovered device, monitoring activities of the discovered device, and/or analyzing information concerning purchases of IoT devices on the LAN. Gleaned identifying information concerning a discovered device can be used to determine or disambiguate the device's identity. Identifying information concerning discovered devices can be transmitted to a backend component, which provides constraint profiles concerning discovered devices, which can be enforced on the LAN.

The disclosed computer-implemented method for classifying electronic files may include (i) identifying an electronic file that is being evaluated for importance by a file-categorization system, (ii) collecting, via at least one user-state monitoring device, information about a physical state of at least one user while the user is interacting with the electronic file, (iii) determining, based on the information about the physical state of the user while the user was interacting with the electronic file, whether the user considers the electronic file to be important, and (iv) classifying, by the file-categorization system and based at least in part on determining whether the user considers the electronic file to be important, the electronic file as an important file. Various other methods, systems, and computer-readable media are also disclosed.

Systems of the present disclosure can detect user activities on endpoint devices based on the interference patterns those actions produce in wireless transmissions between those endpoint devices and another device (e.g., an edge device operating as a web security gateway). A web security gateway sends time-series data describing interference on wireless transmissions sent from, or received by, an agentless endpoint device to a network security service. In response, the network security service uses a machine-learning model to infer a type of an action that occurred on the agentless endpoint device concurrently with the wireless transmissions. The network security service sends an indication of the action type to the web security gateway. The web security gateway applies a network security policy to the action or a network communication associated therewith.

The present disclosure includes a method for maintaining a dynamic geofence. The method receives a set of digital IDs and data pairs from a monitored user credential. Each digital ID was received by the monitored user credential as part of a wireless transmission from a node device, and each digital ID includes one or more attributes. The method retrieves a user policy that includes a required attribute and a threshold distance. The method determines whether at least one of the digital IDs includes an attribute matching the required attribute, and verifies any digital id containing the attribute matching the required attribute. The method determines the distance between the monitored user credential and the node device using the data paired with the digital ID, and determines whether the distance between the monitored user credential and the node device is less than the threshold distance.
