What Is A Cyber Attack?

A cyber-attack is an assault launched by cybercriminals using one or more computers against a single or multiple computers or networks. A cyber-attack can maliciously disable computers, steal data, or use a breached computer as a launch point for other attacks.

Cybercriminals use a variety of methods to launch a cyber-attack, including malware, phishing, ransomware, denial of service, among other methods. Here are the five most common cyber-attacks:

Malware: Malware is a term used to describe malicious software, including spyware, ransomware, viruses, and worms. Malware breaches a network through a vulnerability, typically when a user clicks a dangerous link or email attachment that then installs risky software.

Phishing: Phishing is a technique by which cybercriminals create emails to trick a target into taking some harmful action. The recipient might be tricked into downloading malware that’s disguised as an important document, or urged to click on a link that takes them to a fake website where they’ll be asked for sensitive information like bank usernames and passwords.

Man-In-The-Middle Attack: A man-in-the-middle (MitM) attack is when an attacker intercepts communications between two parties either to secretly eavesdrop or modify traffic traveling between the two. Attackers might use MitM attacks to steal login credentials or personal information, spy on the victim, or sabotage communications or corrupt data.

Ransomware: Ransomware is a form of malware that encrypts a victim’s files. The attacker then demands a ransom from the victim to restore access to the data upon payment. Users are shown instructions for how to pay a fee to get the decryption key.

Denial of Service Attack: A Denial-of-Service (DoS) attack is an attack meant to shut down a machine or network, making it inaccessible to its intended users. DoS attacks accomplish this by flooding the target with traffic, or sending it information that triggers a crash. In both instances, the DoS attack deprives legitimate users of the service or resource they expected.
