A rootkit is a collection of computer software, typically malicious, designed to enable access to a computer or an area of its software that is not otherwise allowed (for example, to an unauthorized user) and often masks its existence or the existence of other software. [1]
However, because a Windows Kernel is thread based and not process based, pointers can be freely modified without any unintended effects. [1] By modifying linked list pointers to wrap around the rootkit process itself, the rootkit becomes invisible to the Windows event viewer and any system integrity applications that rely on this list.
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.
Since GameGuard works like a rootkit, [2] [6] players may experience unintended and potentially unwanted side effects. If set, GameGuard blocks any installation or activation of hardware and peripherals (e.g., a mouse) while the program is running.
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.
In Italy, ALCEI (an association similar to EFF) also reported the rootkit to the Financial Police, asking for an investigation under various computer crime allegations, along with a technical analysis of the rootkit. [37] [38] The U.S. Department of Justice made no comment on whether it would take any criminal action against Sony.
