A cyberweapon is usually sponsored or employed by a state or non-state actor, meets an objective that would otherwise require espionage or the use of force, and is employed against specific targets. A cyberweapon performs an action that would normally require a soldier or spy , and which would be considered either illegal or an act of war if ...
It provides a way to prevent and see vulnerabilities in a specific network system. A honeypot is a decoy used to protect a network from present or future attacks. [2] [3] Honeypots derive their value from the use by attackers. If not interacted with, the honeypot has little to no value.
If an attacker can arrange that the speculatively executed code (which may be directly written by the attacker, or may be a suitable gadget that they have found in the targeted system) operates on secret data that they are unauthorized to access, and has a different effect on the cache for different values of the secret data, they may be able ...
A hardware Trojan is completely characterized by its physical representation and its behavior. The payload of an HT is the entire activity that the Trojan executes when it is triggered. In general, Trojans try to bypass or disable the security fence of a system: for example, leaking confidential information by radio emission .
In computer security, a cold boot attack (or to a lesser extent, a platform reset attack) is a type of side channel attack in which an attacker with physical access to a computer performs a memory dump of a computer's random-access memory (RAM) by performing a hard reset of the target machine.
The deception is designed to lure the attacker in – the attacker may consider this a worthy asset and continue by injecting malware. Deception technology generally allows for automated static and dynamic analysis of this injected malware and provides these reports through automation to the security operations personnel.
Return-oriented programming builds on the borrowed code chunks approach and extends it to provide Turing-complete functionality to the attacker, including loops and conditional branches. [ 9 ] [ 10 ] Put another way, return-oriented programming provides a fully functional "language" that an attacker can use to make a compromised machine perform ...
An attacker who knows the hash function need only feed it arbitrary inputs; one out of two million will have a specific hash value. If the attacker now sends a few hundred requests all chosen to have the same hash value to the server, that will produce a large number of hash collisions, slowing (or possibly stopping) the server with an effect ...
