Abstract: There is disclosed in one example a ransomware mitigation engine, including: a processor; a convolutional neural network configured to provide file type identification (FTI) services including: identifying an access operation of a file as a write to the file or newly creating the file; computing a byte correlation factor for the file; classifying the file as belonging to a file type; determining with a screening confidence that the file type is correct for the file; determining that the screening confidence is below a screening confidence threshold; and circuitry and logic to provide heuristic analysis including: receiving notification that the confidence is below the confidence threshold; performing a statistical analysis of the file to determine a difference between an expected value and a computed value; determining from the difference, with a detection confidence, that the file has been compromised; and identifying the file as having been compromised by a ransomware attack.

Abstract: An electronic device displays a wake screen that includes a representative image in a sequence of images. While displaying the wake screen, the electronic device detects an input that includes a contact over the wake screen. In response to detecting the contact over the wake screen, the electronic device displays, in sequence, a plurality of images in the sequence of images.

Abstract: A dishwashing machine configured to detect the presence of rinse aid in fluid in a washing chamber of the dishwashing machine. An electronic controller selects the drying stage of the dishwashing cycle based on whether rinse aid is present.

Abstract: A dishwasher includes a plurality of electrical wash system components connected to a control system constituted by a user interface controller and a main controller. The user interface controller includes a plurality of user input selectors for establishing model dependent operational parameters for a washing operation. The main controller broadcasts an information packet regarding a desired washing operation in the form of a first set of instructions associated the model dependent operational parameters and a second set of instructions associated with other dishwasher models. The dishwasher is then operated based upon the first set of instructions, while the second set of instructions are automatically filtered out.

Abstract: A multi-compartment dishwasher includes first and second washing units defining corresponding first and second washing tubs or chambers. The dishwasher also includes first and second control boards operatively associated with the first and second washing units respectively. Preferably, the first and second control boards are joined by a communication link that serves as a conduit for sharing data. The dishwasher further includes at least one ID designator that identifies one of the first and second washing units as a primary washing unit and the other of the first and second washing units as a secondary washing unit. The primary and secondary washing units share certain system resources during an overall washing operation, with the primary washing unit having preference over the secondary washing unit.

Abstract: A universal controller is employed in a domestic appliance including a user interface. In order to determine the particular user interface utilized and, correspondingly, the available cycles, features and options of the appliance, a scan of a keypad matrix associated with the user interface is performed to determine the presence and/or absence of shorts used to reflect the existence of permanently closed keys of the matrix. In accordance with the invention, the shorts can be indicated individually, in sequence and/or in combination in order to indicate to the controller which firmware to execute for a particular user interface.
