Top 10 Cyber Security Threats and Vulnerabilities to Aware of in 2021

In this post, we’ve gathered the top 10 cyber security threats and vulnerabilities to Aware of in 2021. Enjoy and stay secure!

Every individual must be aware of the damages that cyber security can do. Vulnerability in only one aspect can cause more trouble than a person imagines. That’s why to avoid the damage that a cyber attack causes, and protect all the data and information, following cyber security trends is a must. You can learn the most up-to-date kinds of a cyber attack by reading this article.

1- Malware

Malware is a common security threat. Malware is the word that is short for malicious software. It is a cyber security threat by its viruses, worms, trojans, and such. Since data protection is essential when it comes to defending your individual or business device, you should know the measures that are being taken to avoid malware.

Protecting from a cyber attack is possible with antivirus software. Besides, to decrease the vulnerability of your devices and strengthen your network, you must be aware of spam. A tight email system can save you from a lot of attacks.

2- Phishing Attacks

A phishing attack is a kind of cyber attack that risks data protection. With this attack, hackers can steal user data, such as login credentials and credit card numbers. Phishing attacks can occur through an email, instant message, or text message. Thus, every person should be aware of a cyber attack that happens via messages for data protection.

The most common phishing attack techniques that can increase the vulnerability of devices are through emails. So, just like malware, cyber security is provided through a tight email system.

3- Ransomware

While ransomware is a kind of malware, it has more specified features. This kind of cyber attack increases the vulnerability of computers, printers, smartphones, wearable, point-of-sale (POS) terminals, or other endpoints. That’s why every business owner and manager need to acknowledge the cyber security trends.

Some of the globally recognized ransomware is WannaCry, Cerber, Locky, Cryptolocker, NotPetya and Petya, Ryuk, and GrandCrab. By knowing cyber security trends, you can skip phishing emails, dangerous email attachments, malicious links on social media, malvertising, infected programs, drive-by infections, Traffic Distribution System (TDS), and self-propagation.

 

Do you wonder about all the general details about cyber security? Do you think you should search for it more since it is an essential topic in the modern world? If yes, you can learn all the things you wonder about cyber security by reading this article. Here you can find everything you need to know about cyber security.


4- Cryptojacking

Crytojacking is the kind of cyber security threat that happens because of unauthorized use of someone else’s computer by hackers to mine cryptocurrency. Since mining cryptocurrency is a popular phenomenon lately, crytojacking can be considered as one of the cyber security trends.

For data protection, preventing your devices from crytojacking is important. It is only possible by training your staff about avoiding a cyber attack.

5- Social Engineering

Social engineering is a kind of cyber attack that causes people to share confidential information. Since it is a relatively easier method of stealing information, hackers prefer this method that ends with devices’ vulnerability. It’s being easy to make social engineering one of the cyber security trends.

Social engineering can occur through an email from a friend, a trusted source. Or it can happen via an email response to a question you never had. When it comes to data protection, the most significant measure is to be aware. You should be aware of every email you respond to, every link you click, and every file you download.

6- Drive-By Attack

Another kind of cyber security trend is drive-by attack. This cyber attack is not so different from others. It is basically a malicious program that installs on your devices. The best defense against drive-by attacks is being cautious. In addition, you should keep all website components up to date.

7- MitM Attack

MitM attack is a kind of attack that is short for the man-in-the-middle attack. Different from the other kinds of cyber attacks, it can be hard to detect MitM attacks. However, it is preventable with some knowledge and caution.

MitM attacks danger the data protection deeply. To prevent this cyber attack, an encryption protocol such as TLS is a must. Otherwise, it can leave the devices vulnerable.

8- SQL Injection

SQL injection is a kind of cyber attack that causes hackers to interfere with the database. With SQL injection, it is even possible for hackers to retrieve hidden data. That’s why everyone needs to check out cyber security trends once in a while.

To prevent this data protection threat, all you have to do is use parameterized queries. In any situation, parameterized queries can be used. But to understand how to use it, further research is required.

9- Zero-Day Exploits

A zero-day exploit is a cyber attack that happens when some kind of vulnerability is detected in a device. That’s why recognizing the vulnerabilities of devices must be done frequently. Since data protection is only achievable by discovering some spots and find a way to fix them, the zero-day exploit is a hard cyber security threat to be protected.

For data protection, users must have a good cyber security system that checks the device regularly and find out every vulnerability. Only this can save the delicate information that is being held in devices.

10- Traffic Interception

The last cyber security trend is traffic interception. This cyber attack is also called eavesdropping. As everyone knows, the web’s encrypted traffic is HTTPS. And according to the studies, 4% and 10% of the HTTPS is intercepted. That means traffic interception is one of the cyber security trends that needs to be payed attention to.

Measurement to take for preventing interception is not easy. But it is possible via some attention. User-agent advertised in the HTTP request is an essential step toward cyber security. To improve security, and decrease vulnerability, this is an important measure everyone should take.

Conclusion

The most significant phenomenon that causes an increase in vulnerability is lack of knowledge. We mentioned some of the cyber security trends in this article, such as (1) malware, (2) phishing attacks, (3) ransomware, (4) Cryptojacking, (5) social engineering, (6) drive-by attack, (7) MitM attack, (8) SQL injection, (9) zero-day exploits, and (10) traffic interception.

By acknowledging these and other cyber attack threats, you can be assured of the cyber security of your devices, and networks. For protecting your data and information, everyone should be aware of measures that should be taken for cyber security.
