A cyberattack is any type of offensive maneuver employed by individuals or whole organizations that targets computer information systems, infrastructures, computer networks, and/or personal computer devices by various means of malicious acts usually originating from an anonymous source that either steals, alters, or destroys a specified target by hacking into a susceptible system.
In the aftermath of the attack, it was revealed at a Senate Armed Services cyber subcommittee hearing that the Department of Homeland Security was not alerted to the ransomware attack and that the Justice Department was not alerted to the ransom type or amount, prompting discussion about the numerous information silos in the government and ...
Because side-channel attacks rely on the relationship between information emitted (leaked) through a side channel and the secret data, countermeasures fall into two main categories: (1) eliminate or reduce the release of such information and (2) eliminate the relationship between the leaked information and the secret data, that is, make the leaked information unrelated, or rather uncorrelated ...
[1] [2] [3] Hacks looking for specific information may only attack users coming from a specific IP address. This also makes the hacks harder to detect and research. [4] The name is derived from predators in the natural world, who wait for an opportunity to attack their prey near watering holes. [5]
The cyber kill chain is the process by which perpetrators carry out cyberattacks. [2] Lockheed Martin adapted the concept of the kill chain from a military setting to information security, using it as a method for modeling intrusions on a computer network. [3] The cyber kill chain model has seen some adoption in the information security ...
This attack is normally harder, a hash of n bits can be broken in 2 (n/2)+1 time steps, but is much more powerful than a classical collision attack. Mathematically stated, given two different prefixes p 1 , p 2 , the attack finds two suffixes s 1 and s 2 such that hash ( p 1 ∥ s 1 ) = hash ( p 2 ∥ s 2 ) (where ∥ is the concatenation ...
