In hacking, a shellcode is a small piece of code used as the payload in the exploitation of a software vulnerability.It is called "shellcode" because it typically starts a command shell from which the attacker can control the compromised machine, but any piece of code that performs a similar task can be called shellcode.
If, due to a hardware fault or program error, the computer fails to restart the watchdog, the timer will elapse and generate a timeout signal. The timeout signal is used to initiate corrective actions. The corrective actions typically include placing the computer and associated hardware in a safe state and invoking a computer reboot.
In computing, a shell is a computer program that exposes an operating system's services to a human user or other programs. In general, operating system shells use either a command-line interface (CLI) or graphical user interface (GUI), depending on a computer's role and particular operation.
Computers with Extensible Firmware Interface, such as IA-64, use a method of device-detection that is not tied to the operating system. [1] Hardware detection operates somewhat differently depending on whether or not Advanced Configuration and Power Interface (ACPI) is supported by the hardware. It passes on the hardware details gathered from ...
Since the 3.74 release, the Syslinux project hosts the Hardware Detection Tool (HDT) project, licensed under the terms of GNU GPL. This tool is a 32-bit module that displays low-level information for any IA-32–compatible system. It provides both a command-line interface and a semi-graphical menu mode for browsing.
A web shell is a shell-like interface that enables a web server to be remotely accessed, often for the purposes of cyberattacks. [1] A web shell is unique in that a web browser is used to interact with it. [2] [3] A web shell could be programmed in any programming language that is supported on a server.
The hardware fault injection method consists in real electrical signals injection into the DUT (devices under testing) in order to disturb it, supposedly well working, at hardware low level, and deceive the control - detection chain (if present) in order to see how and if the fault management strategy is implemented.
