Cyber attacks are severe threats to businesses of all sizes. According to statistics, 43% of cyberattacks in 2021 involved small businesses. So, whether you are a big brand, a startup, or a small-to-medium size business, cyber-attacks are sensitive issues that demand attention. Especially if you consider nearly every business has an online presence and a digital ecosystem.
There are various types of cyber-attacks you should know about to reduce vulnerabilities. Cyber training gets you inside the major types of attacks you should worry about. As a result, it’s easy to identify threats and mitigate them. That said, this article walks you through four types of cyber-attacks. But first, let’s understand the meaning of a cyber-attack.
What Is a Cyber Attack?
A cyber-attack is a data breach that allows cybercriminals to use harmful computer programs to hijack computer systems and networks. Some cybercriminals attack networks and systems for money, while others steal sensitive data for their gains. The digitization of businesses has contributed to the increased cyberattacks in recent years.
Here are the most common cyber-attacks you should know about as you start to digitize your business.
Malware is any malicious software created to harm a server, computer, or network. This malicious software can remain in the host device and only impact it or spread from one device to another. Malware” is any malicious software virus and includes spyware, worms, ransomware, trojans, and adware.
The trojan virus passes itself off as legitimate software while Ransomware blocks all access to your network’s key components. Spyware on the other hand steals all your data while Adware displays advertising content like banners on your screen. Malware works by hacking a network or device through a vulnerability.
Phishing attacks are fake communications that appear to come from a credible source. They are most common in email communication. These attacks trick the user into opening the fake communication. Upon clicking, the attacker can access sensitive data like logins and credit card information. Phishing attacks also focus on installing malware on the user’s computer.
Attackers frequently use emotions like curiosity, urgency, and fear to persuade the user to click on links or open attachments. Phishing attacks are severe therefore, you should scrutinize emails you receive before clicking on any link shared.
Denial of Service Attacks (DoS)
This cyber-attack overwhelms a computer system or network such that it can’t respond to requests. Once the system or network is down, the attacker leverages the opportunity to launch other attacks. DoS primarily intends to deny legitimate users (like employees and account holders) access to resources or services. As a result, the user loses a great deal of time and money.
These attacks decode a user’s password and use it to access sensitive information. These attacks are common since many people reuse the same login credentials across different online accounts. Types of password attacks include brute force attacks which is a guessing game where the hacker uses software to try different password combinations. Using generic and obvious passwords increases the vulnerability of a brute force attack. Another is social engineering where hackers create a believable website to steal internet users’ passwords.
Knowing the different types of cyberattacks help you to implement a cyber security plan. That way, you avoid the impact of cyber-attacks on your business. Cybersecurity measures help you safeguard your computer systems, networks, and their components from illegal digital access.
