What is .HHOO File Extension Ransomware?

hhoo file virus ransomware removal


Ransomware viruses are frequently spread by malicious email attachments, dubious websites, torrents, vulnerabilities, and social engineering techniques. Most victims of STOP/DJVU versions, including the HHOO infection, report downloading the virus from shady sources as setup or crack files for software. When internet users look for popular software cracks, these risky websites frequently show up in the search results. They often offer a password-protected archive file and ask users to download the installation package using a direct link or torrent. Antivirus detection is meant to be avoided by the password protection. But as soon as the user enters the password and launches the infected setup.exe file, the virus inside starts performing destructive deeds.

Demands of HHOO virus:

The HHOO virus is a type of ransomware that encrypts the victim’s files and demands payment in exchange for the decryption key. The HHOO malware’s authors frequently demand payment for the ransom in Bitcoin or other difficult-to-identify cryptic currencies. The exact ransom demand can vary, although it is often several hundred dollars or more. Additionally, the attackers may establish a deadline and threaten to delete the encrypted files if the ransom is not paid within the allotted time. In general, victims of ransomware attacks are urged not to pay the demanded ransom because there is no guarantee that the attackers will release the decryption key even if the ransom is paid. The malicious program called Hhoo Ransomware is made to encrypt data on a victim’s computer, rendering them inaccessible, and then demand a ransom payment in exchange for the decryption key that will release the contents. It is a variation of the STOP/Djvu Ransomware and is now making its way through the internet using false pretenses. Once the computer has been infected by the Hhoo Ransomware, all of the victim’s personal files, including vital documents, pictures, and videos, will be encrypted and given the “.hhoo” file extension. The “_readme.txt” file, which the virus then uses as a method of communication, contains instructions on how to pay the ransom and receive the decryption key required to unlock the encrypted data.

HHOO file virus


Why is .HHOO File Extension dangerous?

When a file is encrypted by the HHOO ransomware, its extension is changed to ‘.HHOO’, which locks its contents and prevents access to the file. Each file that is impacted by the virus has the suffix “.HHOO” added to its original name on the right. For instance, after encryption, a file with the name “document.docx” will now be called “document.docx.HHOO.” Whether it is on the internal disk or network storage, the HHOO virus attacks every file on the victim’s PC. Certain file types found in the OS system folders, including those with the extensions.dll,.lnk,.bat,.ini, and.sys, as well as files with the name “_readme.txt,” are not encrypted by the virus. Consequently, different file kinds, such as films, photographs, documents, and others, are vulnerable to the HHOO file virus.

Do not pay for HHOO ransom!
