Top 25 Latest Computer Viruses 2020 You Must Not Overlook:

Threat of the Month: COVID-19 Malware

Cybercriminals are constantly evolving new tactics to make their malware more adaptable, resilient and damaging than ever to exploit system and network vulnerabilities. Take a look at some of the top cybersecurity threats:

1. CryptoMix Clop Ransomware

It is the new variant of a well-known CryptoMix ransomware family that aims to exploit the whole computer network instead of individual users. Cybersecurity researchers discovered this variant at the end of February 2019. After gaining persistence in the targeted system, this vicious ransomware encrypts all the stored files by appending .CLOP or .CIOP extension to the end of all victim’s file names. 

Whenever the victims’ tries to open an encrypted file, it displays a ransom note informing the users about the attack and compels them to pay the ransom amount in Bitcoin or other cryptocurrencies for the alleged restoration of their encrypted files.

2. Gandcrab Ransomware

GandCrab, one of the most destructive ransomware crypto viruses which was first introduced in January of 2018. GandCrab family variants have been employing various distribution techniques such as Fallout exploit kits, malicious URLs, keygens, GradSoft, RIG, etc. to make an entry into targeted computers. 

Once executed, it terminates all the active tasks and processes running on the system and starts encrypting all kinds of files and folders available on your hard drive. Also it appends .GDCB extension to the end of all file names and displays a ransom message CRAB-DECRYPT.txt with instructions regarding the payment method.

Creators of such infections use advanced AES–256 and RSA-2048 encryption methods and store the decryption key on command and control servers hosted on .bit domains.

One malicious program that should never exist in your computer is Trojan.Glupteba as it has a tendency to bring several other malicious programs with itself. Cyber criminals often distribute the Trojan.Glupteba infection through exploit kits. 

The primary purpose of this latest computer virus is to redirect the users to malicious and third-party sites so that it can download and install more harmful software. Mostly the malware infection enters as a service on the affected Windows system and authorizes various processes on the system by masquerading as a legitimate or authentic software.

After doing this, it gathers users’ data for various IP addresses and then generates the traffic by routing the users towards several malicious domains such as sportpics.xyz, bigdesign.website, kinosport.top, ostdownload.xyz, etc. To prevent such threats, avoid visiting unsafe websites, downloading junk attachments and enable your popup blocker.

4. Cyborg Ransomware

Aids Info Disk Trojan (AIDS), also known as the PC Cyborg ransomware virus, was the first of their kind, introduced via floppy disk back in 1989. The malicious program was designed to count the number of times the operating system of a computer turned on, once the tally reached 90, it used to encrypt all the victim’s data and change the desktop wallpaper with ransom message Cyborg_DECRYPT.txt. 

The ransom note informs the victims about the encryption and asks for a huge sum of money in return if they want to decrypt their files. In addition, recently cyber crooks used an executable file disguised as a .jpg image format to distribute the variant of Cyborg through a fake Microsoft Windows 10 update.

To protect yourself from this ransomware, never click or download any kind of attachment files with .jpg extension coming from an unknown or unsolicited sender.

The Melissa was one of the most dangerous macro viruses, developed by a software programmer named David Lee Smith back in March, 1999. The virus was distributed through an e-mail attachment titled list.doc. When the users opened the document with Microsoft Word, the Melissa virus was injected onto the victim’s computer. 

It was specifically designed to take control of the victim’s Microsoft Outlook program and then mass mail itself to another 50 individuals present in the user’s mail list.

ILOVEYOU, also known as the Love Bug, is one of the deadliest computer worms that exploited more than 10 million systems since it was first discovered in May, 2000. Hackers distributed it via an email message with a document titled as “LOVE-LETTER-FOR-YOU.txt.vbs”.

Upon clicking the interpreted file, it executes the Visual Basic script and starts overwriting a wide array of stored files, including Microsoft Office, media files, and backup files. And then it makes the most of the vulnerabilities of Microsoft Outlook by mass mailing a copy of itself to all other recipients available in the Windows Address Book. 

It allowed malware authors to cripple millions of internet-connected systems and due to the fact many governments and large organizations around the world were forced to shut down their mail delivery systems.

Storm Worm is another dreadful Trojan horse which was first dubbed by the company named F-Secure in the first month of 2007. The malware attack began affecting hundreds of computer using Windows operating systems through an email message with following subject lines:

• 230 dead as storm batters Europe.
• War with Iran is the reality now.
• Occupation of Iran.
• Naked teens attack home director.
• A killer at 11, he’s free at 21 and kill again!

When the user clicks on such attachments, the Storm Worm activates the wincom32 service and downloads several other malware-infected software, turning the compromised system into a bot or zombie computer. In addition, the hackers behind such attacks can remotely control the botnet and further use it to send spam messages and viruses to other computer users.

8. Emotet Malware

Emotet, also known as the Mealybug, is an extremely harmful banking Trojan that acts as a downloader of other malicious programs. Emotet malware is one of the most dangerous malware threats of 2019.

Recently cybersecurity researchers discovered that hackers are now exploiting the fear of global epidemic Coronavirus to spread Emotet malware through malicious email attachments in Japan.

The spam email messages claim to provide the latest information about the outbreak of the Coronavirus and once the users clicks on the document, the Emotet malware gets installed onto their computer. After gaining access to the victim’s computer, it steals both personal and financial information and later trades it on the dark web marketplace. 

A new cryptovirus of ransomware family called B0r0nt0k is targeting thousands of Linux and Windows web servers and encrypting all of the available files with an advanced cipher algorithm.

Instead of directly locking them, the ransomware places .rontok extension at the end of file names. Unlike other ransomware viruses, it makes false entries in the Windows registries, modifies various start-up and browser settings, disables security programs, and locks down the entire system.

The sole purpose of developing such dreadful file-encrypting malware is to extract a hefty amount of ransom money from innocent computer users. And if the victim fails to pay the ransom within a given time, the attacker deletes all the stored files and folders permanently. 

Jigsaw is one of the most dangerous and well-known ransomware families with hundreds of variants of the malware. Cybercriminals often distribute this type of malicious program via junk attachments, free software updates, pirated movie download links, unsafe third party domains, etc.

After successfully invading the targeted system, it encrypts the victim’s files with extensions such as .Fun, .Beep, .FuckedbyGhost, .Game, etc. After doing this, it shows a ransom note which contains information about the payment method and threatens to delete some files permanently every hour if the user fails to transfer the money within a given time period.

However, a company named Emsisoft is now claiming that they’ve managed to develop a decrypting tool for Jigsaw ransomware variants. 

It is another highly dangerous malicious computer virus that belongs to a ransomware family called Thanatos. Similar to other cryptovirus, it encrypts the user’s data and appends .THANATOS extension at the end of each compromised file name. For example, file named luck.txt will be encrypted and renamed to luck.txt.THANATOS. 

After encrypting, it starts blackmailing victims’ by not allowing them to access their files until they pay the ransom amount demanded by the attackers. It is suggested that you should never trust such cybercriminals because once you paid the ransom amount, there’s no guarantee that you would be able to retrieve the lost or encrypted files.

To keep your system secure from such harmful malware infections, it is recommended to install a good antivirus program so you can protect yourself from any future computer virus attacks.
