What is BlackByte Ransomware

BlackByte is the name of a data-locker that encrypts files stored on a device. Such malware is more known as ransomware because it extorts money from victims for the recovery of data. Even though BlackByte is new and little observed, there are enough details to differ it from other infections. One of them is the .blackbyte extension that is appended to each encrypted file. For instance, a piece like 1.pdf will change its extension to 1.pdf.blackbyte and reset the original icon. The next step after encrypting all available data is ransom note creation. BlackByte generates the BlackByte_restoremyfiles.hta file, which displays recovery details.

Within, victims are instructed to contact cyber criminals by e-mail. This action is mandatory to receive further instructions on how to purchase a file decryptor. This decryptor is unique and held only by cybercriminals. The price of ransom can vary from person to person reaching hundreds of dollars. Keep in mind that paying the ransom is always a risk to lose your money for nothing. Many extortionists tend to fool their victims and not send any decryption instruments even after receiving the requested money. Unfortunately, there are no third-party decryptors that can guarantee 100% decryption of BlackByte files. You can try them but bear in mind that third-party decryptors can damage the files unless they knew how to approach them. The best solution, in this case, would be deleting the virus and recovering data from backup copies. If you had them saved on external devices prior to the infection, then your files can be restored safely. Otherwise, you should read our guide below and learn some other recovery methods along with BlackByte removal.

How BlackByte Ransomware infected your computer

BlackByte and other infections of this type are usually installed via script files distributed in various ways. These files can be received in fake messages sent by e-mail. Such messages are usually categorized as spam, making their content even more suspicious. Unfortunately, this does not stop most users from opening such content. Usually, malicious letters contain .docx, .pdf, .exe, .rar, .zip, or .js files that, once opened, may initiate the installation of malware like Blackbyte. Sometimes ransomware developers attach links leading to fake software asking users to download it. The installation of software may be disguised as something legitimate, but install completely different stuff like trojans or direct infections eventually. This is why it is advised to avoid downloading unfamiliar software from landing pages promoted by suspicious figures. Before closing this section, it is worth mentioning some other channels abused by extortionists to deliver malware. This list includes distribution via unprotected RDP configuration, botnets, keyloggers, backdoors, fake software cracking tools, and forged updates promoted via malicious ads. If you are careful and wary enough whilst surfing the web, you will likely avoid all kinds of malware. In addition to that, you can equip yourself with antimalware software that runs live protection against potential threats from the web. Learn more about important preventative measures down below.
