Shortly after shared computing made its debut in the early 1960s, individuals began seeking ways to exploit security vulnerabilities for personal gain. [2] As a result, engineers and computer scientists soon began developing threat modeling concepts for information technology systems.
A vulnerability such as a buffer overflow may be used to execute arbitrary code with privilege elevated to Local System. Alternatively, a system service that is impersonating a lesser user can elevate that user's privileges if errors are not handled correctly while the user is being impersonated (e.g. if the user has introduced a malicious ...

Attack trees are conceptual diagrams showing how an asset, or target, might be attacked. [1] Attack trees have been used in a variety of applications. In the field of information technology, they have been used to describe threats on computer systems and possible attacks to realize those threats. However, their use is not restricted to the ...
Often it is easy to confuse a new exploit with a new attack. New exploits are created all the time for the same attack patterns. The Buffer Overflow Attack Pattern is a good example. There are many known exploits and viruses that take advantage of a Buffer Overflow vulnerability. But they all follow the same pattern.
Meltdown exploits a race condition, inherent in the design of many modern CPUs.This occurs between memory access and privilege checking during instruction processing. . Additionally, combined with a cache side-channel attack, this vulnerability allows a process to bypass the normal privilege checks that isolate the exploit process from accessing data belonging to the operating system and other ...
A remote exploit works over a network and exploits the security vulnerability without any prior access to the vulnerable system. A local exploit requires prior access or physical access to the vulnerable system, and usually increases the privileges of the person running the exploit past those granted by the system administrator. Exploits ...
[4] At the same time, according to Dell: "No 'real-world' exploits of these vulnerabilities [i.e., Meltdown and Spectre] have been reported to date [7 February 2018], though researchers have produced proof-of-concepts." [77] [78] Several procedures to help protect home computers and related devices from the vulnerability have been published.
