The Absolute Home & Office client has trojan and rootkit-like behaviour, but some of its modules have been whitelisted by several antivirus vendors. [6] [8]At the Black Hat Briefings conference in 2009, researchers showed that the implementation of the Computrace/LoJack agent embedded in the BIOS has vulnerabilities and that this "available control of the anti-theft agent allows a highly ...
In 2011 Jonathan Brossard demonstrated a proof-of-concept hardware backdoor called "Rakshasa" which can be installed by anyone with physical access to hardware. It uses coreboot to re-flash the BIOS with a SeaBIOS and iPXE benign bootkit built of legitimate, open-source tools and can fetch malware over the web at boot time. [1]
A backdoor is a typically covert method of bypassing normal authentication or encryption in a computer, product, embedded device (e.g. a home router), or its embodiment (e.g. part of a cryptosystem, algorithm, chipset, or even a "homunculus computer"—a tiny computer-within-a-computer such as that found in Intel's AMT technology).
The default username and password are usually found in the instruction manual (common for all devices) or on the device itself. [citation needed] Default passwords are one of the major contributing factors to large-scale compromises of home routers. [1] Leaving such a password on devices available to the public is a major security risk.
BIOS interrupt calls perform hardware control or I/O functions requested by a program, return system information to the program, or do both. A key element of the purpose of BIOS calls is abstraction - the BIOS calls perform generally defined functions, and the specific details of how those functions are executed on the particular hardware of the system are encapsulated in the BIOS and hidden ...
A backdoor can also be a side effect of a software bug in legitimate software that is exploited by an attacker to gain access to a victim's computer or network. The idea has often been suggested that computer manufacturers preinstall backdoors on their systems to provide technical support for customers, but this has never been reliably verified.

A part of the Intel AMT web management interface, accessible even when the computer is sleeping. Intel Active Management Technology (AMT) is hardware and firmware for remote out-of-band management of select business computers, [1] [2] running on the Intel Management Engine, a microprocessor subsystem not exposed to the user, intended for monitoring, maintenance, updating, and repairing systems ...
