Abstract: An apparatus for detecting a phishing website based on website icons is disclosed. A disclosed example apparatus includes parser circuitry to parse code of a first website, detector circuitry to detect, based on the parsed code, a first website icon and a first Uniform Resource Locator (URL) corresponding to the first website, and hash generator circuitry to generate a first hash of the first website icon, and store the first hash in association with the first URL in a hash entry of an icon hash database, the hash entry to be used for determining that a second website is a phishing website when (a) the first hash matches a second hash of a second website icon corresponding to the second website, and (b) a first portion of the first URL matches a second portion of a second URL corresponding to the second website.

Abstract: An apparatus for detecting a phishing website based on website icons is disclosed. A disclosed example apparatus includes a parser to locate a first website icon corresponding to a first website, an icon hasher to generate a first hash of the first website icon, and a hash checker to determine whether the first hash matches a second hash of a second website icon corresponding to a second website in an icon hash database, the hash checker to, in response to the first hash matching the second hash, determine whether a first portion of a first Uniform Resource Locator (URL) corresponding to the first website matches a second portion of a second URL corresponding to the second website, the hash checker to, in response to the first portion not matching the second portion, identify the first website as a phishing website.

Abstract: The invention provides a processing system, comprising a memory comprising a processor call stack; a stack space usage register configured to determine the stack space usage of the processor call stack and to store a usage parameter indicative of the determined stack space usage; a first threshold register configured to store a pre-determinable first stack level threshold; and a first comparator configured to compare the usage parameter with the first stack level threshold and to output a first interrupt blocking signal, if the usage parameter exceeds the first stack level threshold, the first interrupt blocking signal being configured to block the decoding of interrupt signals input to the processing system and having interrupt priorities lower than or equal to or just lower than a first interrupt priority threshold. The invention further provides a method for stack management, especially in a processing system.

Abstract: In a method of driving a hydraulic system, a contracting force is applied to a hydraulic actuator, thereby causing hydraulic fluid from the hydraulic actuator to flow through a first hydraulic pump motor into a first accumulator, thereby causing the first hydraulic pump motor to apply rotational energy to a shaft. The rotational energy from the shaft is applied to a second hydraulic pump motor, thereby causing hydraulic fluid to be pumped from a second accumulator to a third accumulator so as to store energy in the third accumulator. Once energy is stored in the third accumulator, the second hydraulic pump motor is driven with hydraulic fluid stored in the third accumulator so as to apply rotational energy to the shaft, thereby driving the first hydraulic pump motor to pump hydraulic fluid from the first accumulator to the hydraulic actuator, thereby applying an expanding force to the hydraulic actuator.
