A new malware in development has been spotted by experts, the new strain is known as the Cockblocker ransomware. Learn more about it in our removal guide.
Cockblocker Ransomware Description
The Cockblocker ransomware is a new malware threat that has been recently identified by security researchers. The ransomware is also known under the name RansomwareDisplay. Actually, the virus is a form of “scareware” which doesn’t encrypt or compromise the files. It merely adds the .hannah extension to the target files. However, it is developed to scan victim’s local drives, removable memory devices and shared drives and folders in search for certain file types and appends the extension .hannah as if it implements encipher algorithm and encrypts them.
A ransomware note is then shown to the user which is displayed in an app window. The criminal operators demand a ransom payment of one Bitcoin to restore the user files.
The note states:
“Yo file’s been encrypted nigga
Pays me a bitcoin and I unencrypt them fam”
One bitcoin is close to a thousand dollars. Maybe that’s not enough money for to take English classes.
Update: Files will no longer be accessible or readable by applications on the computer until you type in the string not_a_backdoor in the textbox. The command will help you to get rid of the malicious extension .hannah and regain control over your system and files. As the virus does not compromise the files, yet another way to restore them is to simply remove the .hannah extension. However, you should consider the removal of all malicious files and objects that are created by Cockblocker on your computer.
