8lock8 Ransomware – How Does It Infect
The 8lock8 ransomware is very specific in its methods of infecting users. It’s primary method may be distribution via malicious email URLs, like the example below:
Such infected email links may redirect to malicious URLs that may inject a script which compromises your PC and may download the payload of 8lock8 onto your computer.

8lock8 Ransomware In Detail
8lock8 otherwise known as EightLockEight is believed to have similar coding to another notorious ransomware infection – HiddenTear which is an open source project and has been associated with many other infections, like Sanction ransomware. The one thing that may characterize all ransomware using Hidden Tear is that they may directly attack the drives of infected PCs, changing their settings and encrypting the data in them.
After its payload has been dropped on the infected computer, it may be situated in one of the following locations:
The payload may be set to delete the shadow copies and other backups of Windows, by using vssadmin scripts. This is successfully done with the usage of privilege escalation. The command for deleting Shadow Volume Copies is the following:
→ vssadmin delete shadows /for={Your volume} /all /shadow={ID}] /quiet
Besides that, the ransomware may modify the Registry Editor(Regedit) in Windows so that its encryptor runs on Windows startup. This is possible by entering custom values for its executable in the following key:
→ HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
If the encryptor is executed, according to researcher Demonslay335, who has also developed a decryptor for the ransomware, it begins to scan for and encrypt the following file types
→ zip,.bmp, .csv, .doc, .docx,., sql, .txt, .wav, .xls, ..avi, xlsx, .xml, ..ppt, .pptx, .rar, .sln, .htm, .html, .jpg, .mdb, .odt, .pdf, .php, .png, asp, .aspx
After it encrypts files each and every drive that Is active on the compromised computer with a very strong AES-256 encryption cipher, the infection adds its 8lock8 extension to the encrypted files, for example:
→ New Text Document.txt.8lock8
After encryption, the files are unable to be opened and 8lock8 ransomware creates the following ransom note, named “READ_IT.txt” so that the user can see it:
→ “Files have been encrypted!Файлы были зашифрованы
It uses cryptographically strong algorithm!Используется криптостойкий алгоритм
contact by e-mail: [email protected] or [email protected]
to identify , use lower hash!для идентификации используйте нижний хэш
{Random hash identification}”Source:Demonslay335
