What is CoronaLock Ransomware

Discovered in 2020, CoronaLock restricts access to user’s data by encrypting it with ChaCha, AES and RSA algorithms. Files compromised by this ransomware, experience a change in extension to either .pandemic, .corona-lock or .biglock. For example, if 1.mp4 gets modified by the virus, it will migrate to 1.mp4.pandemic, 1.mp4.corona-lock or 1.mp4.biglock. After this, extortionists display ransom information in the note (PROTECT_INFO.TXT, !!!READ_ME!!!.TXT or README_LOCK.TXT) that is dropped on the desktop.

Interestingly enough, people who get attacked with ".biglock" extension, do not have any contact information in the ransom note to connect with cybercriminals. It seems like its developers forgot to include it before the release. In the meantime, ".corona-lock" versions do not have that drawback and contain e-mail in the text file. If you want to take a test-decryption, you are free to send them one file. Despite the fact that data remains encrypted even after virus deletion, you have to get rid of it to prevent further encryptions. Our free guide below will help you to do so.

How CoronaLock Ransomware infected your computer

Very often, users get malware from e-mail spam messages, fake software cracking tools, botnets, keyloggers, trojans, and other suspicious downloads. Unfortunately, spam messages tend to contain malicious attachments (MS Office documents, PDFs, executables, JavaScript files, etc.) that lead to numerous infections caused by the help of executable scripts. Trojans are known to be a buffer for different malware. Once it gets active, chain-infections will be initiated to deliver other malware. Be careful and do not trust click-bait banners and ads, and never download unknown software from the web.
