The Alureon bootkit was first identified around 2007. [1] Personal computers are usually infected when users manually download and install Trojan software. Alureon is known to have been bundled with the rogue security software, "Security Essentials 2010". [2]
XCP.Sony.Rootkit loads a system filter driver which intercepts all calls for process, directory or registry listings, even those unrelated to the Sony BMG application. This rootkit driver modifies what information is visible to the operating system in order to cloak the Sony BMG software. This is commonly referred to as rootkit technology.
Blue Pill is the codename for a rootkit based on x86 virtualization.Blue Pill originally required AMD-V (Pacifica) virtualization support, but was later ported to support Intel VT-x (Vanderpool) as well.
Rootkits are notoriously used by the black hat hacking community. A rootkit allows an attacker to subvert a compromised system. This subversion can take place at the application level, as is the case for the early rootkits that replaced a set of common administrative tools, but can be more dangerous when it occurs at the kernel level.
rkhunter (Rootkit Hunter) is a Unix-based tool that scans for rootkits, backdoors and possible local exploits. [1] It does this by comparing SHA-1 hashes of important files with known good ones in online databases, searching for default directories (of rootkits), wrong permissions, hidden files, suspicious strings in kernel modules, and special tests for Linux and FreeBSD. rkhunter is notable ...
The arrow represents a rootkit gaining access to the kernel, and the little gate represents normal privilege elevation, where the user has to enter an Administrator username and password. Privilege escalation is the act of exploiting a bug , a design flaw , or a configuration oversight in an operating system or software application to gain ...
The original application was not forensics, but rootkit detection and process hiding – showing how physical memory forensics grew partly from rootkit development. [23] With the release of HBGary's product Responder in 2008, Hoglund was one of the first to deliver OS reconstruction to the market, pivotal in the use of physical memory to ...
