Emsisoft releases a free decrypter for MegaLocker Ransomware
Our research team has uncovered a new ransomware campaign popularly known as MegaLocker or the NamPoHyu Virus and the decrypter for the dangerous malware was developed with the help of the group Ransomware Hunting Team.
Below is a table of the latest count of successful decryptions per country.
If you’re a victim of this ransomware, please follow the instructions below and DO NOT PAY the ransom.
MegaLocker is a ransomware that encrypts victims’ files using AES-128 ECB, and adds the extension “.nampohyu” to files. The ransom note “!DECRYPT_INSTRUCTION.TXT” instructs the victim to go to a Tor website to contact the criminals.
The ransom note contains the following text:
What happened to your files ?
All of your files were protected by a strong encryption with AES cbc-128 using NamPoHyu Virus. What does this mean ?
This means that the structure and data within your files have been irrevocably changed,
you will not be able to work with them, read them or see them,
it is the same thing as losing them forever, but with our help, you can restore them. The encryption key and ID are unique to your computer, so you are guaranteed to be able to return your files.
Your unique id: [redacted hex] What do I do ?
You can buy decryption for 1000$.
