What is happy ransomware? And how does it carry out its attack?

.happy ransomware is a new crypto-virus that appears to be a new variant of Bad Rabbit ransomware. This dangerous threat was discovered in the last week of January 2019 and is reported to be causing a menace to several users. It uses a .happy extension in marking its encrypted files which cannot be opened once encrypted. It starts to carry out its attack once its malicious file is opened by a user.

happy Ransomware

This malicious file is the one that initiates the attack and connects the computer to a remote server. From this remote server, .happy ransomware downloads the following files and places them in several Windows directories.

  • T1.exe
  • T1.pdb
  • .exe – randomly named executable
  • qqf85h6c.bmp – the picture with the note loaded on the service
  • don.bmp
  • screen.jpg

After these files are downloaded, .happy ransomware will continue its attack by further modifying the infected computer. It creates and modifies existing registry entries in order to allow it to run automatically in every system boot. Once this crypto-malware achieves persistence, it begins encrypting files using the AES encryption algorithm. Following data encryption, it appends the .happy extension to every compromised file and opens a text file named “HIT BY RANSOMWARE.txt” which contains a message that states:

ln order to decrypt your files, you must decompile the ransomware
(which is easy) and find out the encryption method (easy as well)
Next time, think before you execute. Your next ransomware couldn’t be
that easy to crack and you would lose all your files 🙁

It also opens an image file that contains the following content:

“If you access this page your computer has been encrypted.
Time left before the price goes up:
Price for decryption:
-0.05 BTC
Enter your personal key or your bitcoin address.”

How is the payload file of .happy ransomware distributed online?

  • Cracks
