Cybercriminals are coming up with new and more cunning ways of infiltrating other people’s devices to steal their data, information, or even money. They use malicious software that targets huge corporations, businesses, and individuals. A good example is the CovidWorldCry ransomware, which is somewhat the new kid on the block (discovered in late May 2020).

What is CovidWorldCry Ransomware?

This is a new COVID-19-themed virus that is also known as BigLock or CoronaLock. It locks the data and some system files stored on the infected machine, and asks for a ransom in the form of Bitcoin. The malware not only encrypts the data but also modifies the Windows boot stage, which is quite unusual for ransomware as most of them only encrypt user-related files.

The ransomware was released in two different versions, and it uses ChaCha + AES encryption algorithms to lock pictures, images, videos, files, databases, and other personal files on the host computer.

What Can CovidWorldCry Ransomware Do?

Once it has gotten into your computer, the ransomware does not start encrypting files right away. It first prepares the host for proper file locking by infecting all files stored on it. After successful infection, the virus then performs the following:

  • Deletes Shadow Volume copies
  • Manipulates the storage size attributed for Shadow Volume copies
  • Initiates changes within the registry
  • Terminates processes and starts new ones
  • Drops many malicious files on the system

After the infection process, data stored in the device is locked, and users can no longer gain access to it. The encrypted files are renamed by appending the malware’s extension “.corona-lock.”

How Is the Data-Locking Virus Spread?

CovidWorldCry ransomware spreads via the Rig Exploit kit as the primary attack vector. If you notice double encryption, it means that your device was infected with CovidWorldCry ransomware alongside Djvu. Such secondary infections are difficult to get rid of.

Since CovidWorldCry ransomware is mostly distributed via exploit kits, users who have vulnerable software on their computers are at a higher risk of infection.

How to Remove CovidWorldCry Ransomware

All the locked data requires a particular key to unlock. If you can’t get that key to decipher the already encrypted data, what do you do? Don’t worry – we’ll show you how to get rid of CovidWorldCry ransomware safely using other methods without the key:
