What Are The Common Cyber Attacks And How To Avoid Them?

A cyberattack is an attempt to break into a computer network or system by hackers, cybercriminals, or other digital enemies to steal, alter, destroy, or disclose information. Cyberattacks can target a broad spectrum of governments, businesses, and individual users. Hackers typically aim to obtain sensitive and important company resources, like payment information, customer information, and intellectual property (IP), when they target corporations or other organizations.

Cyberattacks are destructive in several ways. Executing an attack may result in data breaches, which may cause data loss or modification. Financial losses, diminished customer trust, and reputational harm are all experienced by organizations. 

Common Types Of Cyber Attacks:

Although there are numerous ways for an attacker to get access to an IT system, most cyberattacks use methods that are quite similar. Below is a list of some of the most common types of cyberattacks:

1. Malware:
   Malware, which can infect computers through reputable websites, apps, or file attachments, is undesired software that has been installed on a system without authorization. Malware can infiltrate a system using a variety of techniques, including encrypting files, presenting advertisements, preventing access to data, and duplicating itself. Malware may be found in a wide variety of formats, including keyloggers, botnets, worms, trojans, spyware, adware, and ransomware. Malware attacks infiltrate the network by taking advantage of an anomaly and inserting harmful code. 
2. Phishing:
   Phishing is a type of cyberattack in which malicious websites or emails are used to get sensitive data, including account numbers, credit card numbers, and login credentials. It occasionally involves targeted spear phishing, which sends false emails to specific people or companies. Sometimes, they are powerful people who steal cash or private information. To get the subject to reveal private information that will be utilized fraudulently.
3. Ransomware:
   Ransomware is when malicious data encrypts data and prevents the victim from accessing it. Typically, this malicious software is used to extort money in exchange for the ability to decode the attacker’s encrypted files, folders, and computers.
   Next, the information is encrypted by the malicious program by taking advantage of a system weakness. 
4. Password Attacks:
   A password attack might be as easy as someone figuring out your password correctly, or it can involve more sophisticated techniques like keylogging, in which hackers track the data you type to identify passwords. Using automated password-guessing software, the attacker can attempt every combination in the dictionary and ultimately guess the password.
5. DoS and DDoS Attack:
   A denial of service (DoS) attack is executed by a single attacker. Still, a distributed denial of service (DDoS) attack is launched by several attacker-controlled workstations that are frequently infected with malware. These attacks primarily aim to disrupt the targeted system or service, rendering it inaccessible to authorized users. When DoS or DDoS attacks are successful, the system may become open to other attacks. 
6. Zero-Day Attacks:
   A zero-day exploit is a type of cyberattack in which criminals take advantage of a vulnerability that was only found in widely used operating systems This makes it possible for attackers to take advantage of the vulnerability while it is still unfixed and target companies who use that software.

How to Prevent Cyber Attacks?

To prevent cyberattacks, everyone should take into account these suggestions which are verified by cybersecurity education professionals.

Malware: Use anti-malware and spam protection software, spot phishing emails and websites, enforce strict password requirements, keep software updated, and restrict access to systems and data to prevent malware infections.

Phishing:  Never open an email from a sender you don’t know. Examine emails you receive carefully for flaws and serious mistakes. 

Ransomware: Ensure your antivirus and antimalware software are up to date to prevent ransomware. Never click on links or open attachments from unverified or unknown sources. 

Password attacks: Multi-factor authentication (MFA), penetration testing, and strong password policies are all necessary to prevent password attacks. 

DoS and DDoS: A strong network architecture, including firewalls, traffic filtering, rate limitation, and cooperation with ISPs, is necessary to prevent DoS and DDoS attacks, especially when working with a managed network services provider.

Man-in-the-middle (MITM) attacks: When connecting over public Wi-Fi, it is essential to use a secure VPN service to protect yourself from MITM attacks. Using a secure VPN service is the ideal approach.

Zero-day attack: Next-generation antivirus software can provide some defense against zero-day exploits, but traditional antivirus software might not be able to stop them entirely.
