Attack

Cyber Attack

Definition: A cyber attack refers to the type of attack or manipulation by a nation, an individual, a group, or an organization that attacks and intrudes into a computer network, computer information system, infrastructure, and / or personal computer equipment through various malicious acts, usually from anonymous sources, in changing or destroying targeted targets by invading susceptible software. Under different circumstances, these can be marked as cyber movements, cyberwars or cyberterrorism. Cyber attacks may include the installation of spyware on a PC in an attempt to destroy the entire country’s infrastructure. Cyber attacks can fall into two broad categories: hacking, whose goal is to disable or take the target computer off-line or to attack the target computer’s data and potentially gain administrator rights data and second, breaches, where system and database are intruded to steal or detain data and in many cases damage the system by the attacker. Attackers use a variety of techniques to achieve these goals, including:

Malicious software (malware) downloaded to the target computer, can do anything from stealing data encrypted files and asking for ransom

  • Phishing emails designed to cheat victims, give up passwords, or take other harmful actions
  • Denial of service attacks that overwhelm the web server with false traffic
  • Man-in-the-middle attacks that trick the target computer into a damaged network
  • Identity theft
  • Data leakage
  • Espionage

Of course, these technologies can be used together. For example, phishing emails may trick users into downloading malware.
