Abstract: Media, methods, and systems are disclosed for hosting an event-based application. Application instructions corresponding to processing steps to be performed in response to particular events are received from a development environment. The events are associated with a group-based communication channel. An application comprising computer-executable instructions is generated based on the application instructions and metadata associated with the events. In response to detecting one or more of the events, execution of the computer-executable instructions is triggered. A response is received corresponding to output from applying the processing steps to the events. A message is posted into the respective communication channel corresponding to the response.

Abstract: Techniques for using a detector coupled to a controller area network (CAN) bus of a vehicle system to identify and generate alerts in response to wake-up attacks on the vehicle system. Techniques include an electronic control unit (ECU) sending a wake-up message across the CAN bus that is detected by the detector. The detector includes memory and a processor to identify the timestamp of the wake-up message when the vehicle ignition is off. The detector determines a total operational time for the ECU over an observation time period and generates a notification of a wake-up anomaly when the total operational time over the observation time period exceeds a predetermined threshold.

Abstract: A node of a network receives account access information (AAI) for an account that a user has with a system. The node causes a first record to be added to a distributed ledger that is used for managing access to the account, wherein the first record includes the AAI or an encrypted storage identifier that identifies a storage location for the AAI. The node determines a likelihood that the account is being accessed by the user based on the AAI and/or historical AAI for one or more accounts, that include the account, that are used to access the system. The node causes a second record that includes a value representing the likelihood to be added to the distributed ledger. The node causes one or more other nodes of the network to be alerted that the first record and the second record have been added to the distributed ledger.

Abstract: An electronic lockbox includes a latching apparatus that uses a rotary actuator with multiple positions to achieve multiple locking states. Multiple positions of the actuator are detected, using optical sensors. The locking mechanism includes an outer sleeve and an inner cylindrical barrel that are coupled with torsion springs. The lockbox has a shackle and a key bin that include latch pins which are retained by the inner barrel when in the locked state, and the barrel can be rotated to either release the shackle or to release the key bin that typically holds a building's key. During insertion of a latch pin into the rotatable barrel, the maximum torque imparted on a first spur gear by the torsion spring, at a maximum rotation angle of the rotatable barrel, is sufficient to rotate the barrel back to its neutral position after the latch pin has been fully inserted into the barrel, and is less than or equal to a back drive torque limit of a prime mover of the rotary actuator.
