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.
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 ...
A "backdoor" allowed an operator with sysadmin status to deactivate the exchange's transaction log, alarms and access commands related to the surveillance capability. [18] The rootkit was discovered after the intruders installed a faulty update, which caused SMS texts to be undelivered, leading to an automated failure report being generated.
The company started as a manufacturer of complete motherboards, positioning itself in the high-end segment. Its first customer was PCs Limited, [4] later known as Dell Computer. [6] As hardware activity moved progressively to Taiwan-based original design manufacturers, [7] AMI continued to develop BIOS firmware for major motherboard ...
A PBA environment serves as an extension of the BIOS, UEFI or boot firmware and guarantees a secure, tamper-proof environment external to the operating system as a trusted authentication layer. [2] The PBA prevents any operating system from loading until the user has confirmed he/she has the correct password to unlock the computer. [ 2 ]
