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 ...
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).
Hardware backdoors are backdoors in hardware, such as code inside hardware or firmware of computer chips. [1] The backdoors may be directly implemented as hardware Trojans in the integrated circuit. Hardware backdoors are intended to undermine security in smartcards and other cryptoprocessors unless investment is made in anti-backdoor design ...
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 ]
The Worst Passwords List is an annual list of the 25 most common passwords from each year as produced by internet security firm SplashData. [4] Since 2011, the firm has published the list based on data examined from millions of passwords leaked in data breaches, mostly in North America and Western Europe, over each year.
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.
Intel responded by saying, "Intel does not put backdoors in its products, nor do our products give Intel control or access to computing systems without the explicit permission of the end user." [5] and "Intel does not and will not design backdoors for access into its products. Recent reports claiming otherwise are misinformed and blatantly false.
An unlocked bootloader, showing additional available options. Bootloader unlocking is the process of disabling the bootloader security that makes secure boot possible. It can make advanced customizations possible, such as installing custom firmware.
