Features of The Threat

The HappyLocker ransomware is based on the code of HidenTear ransomware family. Hidden Tear ransomware samples were created for educational purposes, however it does not take a long until the first malicious ransomware variants based on its source code have appeared. Other ransomware variants based on the source code that is published online are MasterBuster, CerberTear, Pokemon Go .exe and HollyCrypt.

HappyLocker cryptovirus may hide its payloads in some major Windows folders like:

  • %AppData%
  • %Roaming%
  • %Temp%
  • %User’s Profile%
  • %System32%

The malicious files of HappyLocker ransomware might replace or modify critical system files. Furthermore, some Windows Registry keys are probably changed by the ransomware. Such modifications are usually performed with the purpose of automatic start of the malicious HappyLocker’s files whenever the OS is launched.

The core of Happy Locker ransomware is the encryption function. Upon establishing and running its malicious files on the computer, it performs a scan of all drives. HappyLocker ransomware targets particular file types that it encrypts with strong (AES) encoding encipher. The target list may include images, documents, audio and video files, databases and other commonly used file types. At the end of the encryption, it appends the suffix .happy to the file name as an indicator that the file is encrypted.

After the encryption process, the ransomware drops two files on the victim’s desktop. A text document named “READDDDDDD.txt” and an image – “READ.jpg”. Both files prompt victims to enter the “Happy Decryptor Page” website. The page presents special Happy Decryptor software which allows victims to decrypt and return control to all encrypted files. The HappyLocker payment service resembles the one used by Locky ransomware creators.


Victims are asked to send 0.1 BTC to cyber criminals’ Bitcoin address. However, most of the ransomware viruses based on Hidden Tear source code are successfully decrypted. So after the removal of the threat, all victims of HappyLocker may try to restore the data using the Hidden Tear decryptor. Even if this approach doesn’t restore the data our advise is not to fund the malicious actions of the attackers and patiently wait until a decryption solution is developed.

The image file “READ.jpg” might be displayed automatically on the desktop. It depicts a text that reads as follow:

All your files are encrypted with HAPPY Ciphers
To Decrypt:
– Open This Page : http://ysasite.com/happy
– Follow All Steps “
