NEW DELHI: Managing a business is difficult enough, but the recent evolution of malware has made it worse. Every year, millions of new malware strains emerge, each of which is more difficult to detect than the previous one. Malware has had a particularly good year in 2021, owing to an increase in people working from home and other hardships.
As the year progresses, let’s take a look at ten of the most dangerous malware to be aware of.
1. Ransomware Clop
Clop is a variant of the CryptoMix ransomware family. This variant primarily targets users who use Windows as their primary operating system. It is capable of attacking entire networks as opposed to individual computers. This ransomware has the ability to freeze hundreds of Windows processes and programmes, rendering the victim powerless to stop it.
2. Gameover Zeus
This malware is well-known for getting victims’ financial information and uses peer-to-peer infrastructure. It infiltrates a user’s computer through spam messages. It then joins a botnet and watches whenever you enter sensitive information into your online bank account or payment service.
The value of cryptocurrency fluctuates over time, and the amount of effort required is prohibitively expensive for many users. When hackers send out spam emails with crypto mining code embedded in them, this is known as cryptojacking. When the user clicks the link, the code begins mining coins on the computer. The victim’s computer bears the brunt of the work, and the hacker obtains all of the cryptocurrency coins.
AlienBot malware can infect your business-related mobile apps. This malware infiltrates legitimate apps where users enter login information. The malware steals the data and then takes control of the victim’s entire device.
5. REvil Ransomware
To regain access to their files and programmes, this ransomware requires the user to pay the hacker in Bitcoin. The ransom will double after the initial period expires. This ransomware is notorious for leaking celebrity confidential data onto the dark web.
6. Ryuk Ransomware
Ryuk is well-known in the ransomware community. Ryuk, like the others mentioned, will infiltrate your device and disable your files, programmes, and the device’s system. This ransomware has become more common in recent years as more people work from home, away from the security of IT at the office. They are more likely to unintentionally grant Ryuk access to their computer via Remote Desktop Services.
This ransomware is aimed at both small and large businesses. When the hackers extract the data from the network, a portion of it will be published on the dark web right away. The victim will be given proof of this, as well as a ransom letter for the remaining amount. When victims see that the hacker is serious about the threat, they are more likely to pay the ransom quickly.
Tycoon is Java-based ransomware that targets both Windows and Linux users. The ransomware will infiltrate the system via an insecure server connection. After that, it can prevent anti-virus software from being detected.
9. Phishing Emails regarding COVID-19
While the world is dealing with the COVID-19 pandemic and its aftermath, hackers are taking advantage of the situation to target vulnerable people. In 2021, cybercriminals began sending out mass emails claiming to contain pandemic updates or relief payments. When the individual clicks on the provided link, malware is downloaded onto their device, which either freezes their files or steals their login credentials.
It is critical to remember that you are unlikely to receive pandemic updates via email from random people. If you receive an email from someone you don’t know, run their name through an online background check before opening it. You will be able to see their place of employment and if they have one, their criminal record. You will most likely discover that the email is spam, and you should simply delete it.
10. Operating System Updates
Most users are now aware that they should only open files and emails from people they know. Hackers are aware of this and are masking their email addresses so that they appear to be from verified Microsoft employees. According to the email, it contains information about new Windows updates. When the user attempts to download the file, it appears as an ‘.exe’ file. This is most likely ransomware, which will encrypt all of your files and prevent you from accessing them. To obtain the decrypting software, you must pay the hacker money.
The Consequences of Malware
Businesses contain a large amount of confidential data that must be kept secure at all times. This is especially true when dealing with clients’ addresses, phone numbers, email addresses, and financial information. If your customers’ data is compromised as a result of a data breach, it will be extremely difficult to regain their trust.
How to Prevent Malware
One of the most important things you can do is to keep your device updated at all times. Every new patch adds another layer of defence against malicious malware. You should also use your anti-virus software and run regular scans for any signs of malicious activity.
You should also exercise caution when visiting unfamiliar websites. If in doubt, do not enter any information into the site and leave as soon as possible. Before you click on a website, most anti-virus software will display a green checkmark to indicate its safety. If it does not have that checkmark, you should look for a more reputable site instead.
Another indicator of a website’s reputation is the presence of “HTTPS” at the beginning of the URL. This means that it is secure and should be safe to enter sensitive information.
