Common Types of Cyber Attacks

Cybersecurity is the practice of protecting systems, networks, and programs from digital attacks. These cyber attacks are usually aimed at accessing, changing, or destroying sensitive information; extorting money from users; or interrupting normal business processes.

 

Implementing effective cybersecurity measures is particularly challenging today because there are more devices than people, and attackers are becoming more innovative.

 

Types of Cybersecurity Threats

 

1. Denial-of-service (DoS) and distributed denial-of-service (DDoS) attacks

A denial-of-service attack overwhelms a system’s resources so that it cannot respond to service requests. A DDoS attack is also an attack on the system’s resources, but it is launched from a large number of other host machines that are infected by malicious software controlled by the attacker.

 

2. Man-in-the-Middle Attacks
When you’re on the internet, your computer has a lot of small back-and-forth transactions with servers around the world letting them know who you are and requesting specific websites or services. In return, if everything goes as it should, the web servers should respond to your request by giving you the information you’re accessing. This process, or session, happens whether you are simply browsing or when you are logging into a website with your username and password.

The session between your computer and the remote web server is given a unique session ID, which should stay private between the two parties; however, an attacker can hijack the session by capturing the session ID and posing as the computer making a request, allowing them to log in as an unsuspecting user and gain access to unauthorized information on the web server.

 

3. Phishing attacks
Phishing email attacks are untargeted, mass emails sent to many recipients that are meant to acquire sensitive information (e.g. password, username or bank details). With this information, a hacker can perform a data breach. It’s difficult to spot a phishing email because it’s disguised as a trustworthy entity that prompts a recipient to visit a malicious website.

 

4. Malware
Among the most common cybersecurity threats, malware refers to multiple forms of harmful software executed when a user mistakenly downloads it. Some of the most recent cybersecurity breaches involved malware, including the ransomware attacks WannaCry and Petya/NotPetya. Traditional malware such as viruses, Trojans, and backdoors also remain persistent.
