10 Most Dangerous Virus & Malware in 2021
Viruses and malware have become more advanced and dangerous in the world of technology. It is difficult for computer users to keep their data safe and secure. These viruses are difficult to detect but with the right strategy, you will be in a better position to beat the threats.
If you want to keep your data safe and secure, the first thing you need to know is about viruses and malware. In our previous articles, we discussed many types of phishing attacks. If you are interested then check out our phishing and hacking series.
In this article, we are going to discuss-
10 Most Dangerous Virus & Malware in 2021
- Clop Ransomware
- Fake Windows Updates (Hidden Ransomware)
- Zeus Gameover
- Ransomware as a Service (RaaS)
- News Malware Attacks
- IoT Device Attacks
- Social Engineering
- Artificial Intelligence (AI) Attacks
Clop is a ransomware-type of malware and a type of malicious software designed to block computers. It also leaves a file called "Please read me" that explains what happened to your computer and how to send a payment to the hacker to fix it. There is a fixed limit on the amount to be paid and the amount can be increased if the money is not paid before the stipulated time. This money is paid through a virtual currency called bitcoin. The computer remains encrypted until payment is made.
Fake Windows Updates (Hidden Ransomware)
Fake Windows Update installs ransomware on your PC where victims receive emails that claim to be from Microsoft. The ransomware contained in these emails is called cyborg. It encrypts all your files and programs and demands payment for un-encrypting the files.
GameOver Zeus is a malware extension of the Zeus family. Cybercriminals use it to "filter" money from banking customers. It was discovered in 2011. This malware was created by a Russian hacker named Evgeny Mikhailovich Bogachev. It is believed to be spread through the use of the Cutwell botnet. Zeus typically promotes via email or drive-by downloads. These emails can often use social engineering techniques that lead victims to fake versions of popular social networking sites such as MySpace, Facebook, or LinkedIn.
Ransomware as a Service (RaaS)
Ransomware as a Service (RaaS) is a pay-for-use malware offering. It is designed to perform extortion on stolen or encrypted data, which is known as ransomware. In short, someone made ransomware. The ransomware developer offers a ransomware builder and the builder runs for a specific amount of time until you pay for it again.
It is now ransomware as a service because it is now being sold online (so it is a service).
News Malware Attacks
Cybercriminals often use current news and global events to target people with malware. For example- hackers using the wave of the coronavirus or the COVID-19 outbreak to target individuals with malware. Hackers send out emails disguised as legitimate information about the outbreak. Readers are asked to click on a link to learn more about the information, but the link contains malware that copies files on your device and steals your personal and sensitive information.
Fleeceware is a type of malware mobile application that comes with hidden exorbitant subscription fees. These applications also take advantage of users who do not know how to unsubscribe to charge for a long time after deleting the application. Recent research has found that by 2020 more than 600 million Android users have downloaded "Fleeceware" on their devices.
IoT Device Attacks
With the popularity of IoT (Internet of Things) devices rising in 2021, things like smart speakers and video doorbell hackers are trying to exploit these devices for valuable information.
There are many reasons why hackers choose to target IoT devices. For example, most IoT devices do not have enough storage to establish proper security measures. These tools often contain easy-to-access data such as passwords and usernames, which can be used by hackers to log in to user accounts and steal valuable information such as banking details.
Social engineering is the art of manipulating the users of a computing system into revealing important/confidential information that can be used to gain unauthorized access to a computer system in a secure network.
In our previous article, we had discussed social engineering in detail. Check it out if you are interested.
In this attack, a hacker hijacks a target's processing power to mine cryptocurrency on behalf of the hacker. Hackers have two methods to secretly mine the cryptocurrency on the victim's computer.
One is to trick victims into loading crypto-mining code onto their computers. Strategies like phishing do this: Victims receive a legitimate-looking email that encourages them to click a link. Link runs a system that places crypto-mining scripts on the computer, then runs in the background as the victim works.
Another approach is to inject a script into a website, or an advertisement that is delivered to multiple sites, once victims visit the website or an infected ad pops up in their browser, the script is automated. is properly executed. There is no code stored in the victim's computer. Whatever method is used in this attack, the code runs complex mathematical problems on the victim's computer and sends all the results to a server that the hacker controls.
Artificial Intelligence (AI) Attacks
Most of the hackers are taking advantage of artificial intelligence technology to create links to help them get into any system. This is the technique that many cybersecurity companies use to deal with hackers. In 2021 and the coming years, people should be prepared to deal with more advanced and devastating artificial intelligence-based viruses.
