What is .NamPoHyu files virus? Is .NamPoHyu files virus a variant of the MegaLocker ransomware family? What kind of encryption does the .NamPoHyu files virus use?
.NamPoHyu Files Virus is a cryptovirus that targets Ubuntu Apache servers, NAS storages, along with other servers used for various purposes, be it running a website (domain) or ones used for storing data. Mac and PC operating systems can be affected. The virus encrypts files by using the AES encryption algorithm via CBC (Cipher Block Chaining) and places a ransom note. With the ransom note, the cybercriminals that are behind the virus demand money as a ransom to get the files restored. Files will receive a custom extension, which is .NamPoHyu but other variants are not excluded from appearing. The .NamPoHyu Files Virus is called NamPoHyu Virus and it is actually a variant of the MegaLocker ransomware.

.NamPoHyu Files Virus – Update May, 2019
There’s some great news for victims of the NamPoHyu ransomware – a decryptor is now available. Emsisoft developers have released a decryptor for the ransomware, and its victims can now use the tool to recover their files for free.
NamPoHyu is a variant of the MegaLocker ransomware, meaning that the decryptor will also work for MegaLocker victims. As explained by the developers of the decryption tool, to use it, you will require one of the ransom notes left by the malware. You can download the NamPoHyu dectyptor and recover your files. Emsisoft has also provided a detailed guide on how to use their tool.
.NamPoHyu Files Virus – What Does It Do?
Users have contacted us and reported new information about the infection method of the .NamPoHyu virus. The report states that the NAS storage device of one user was infected remotely, due to the router accidentally placing the server in a Virtual DMZ, hence making the public IP open. The same user had checked his own WDmycloud IP on his router and also found out that the IP was in a DMZ. Thus, the NAS device was encrypted, but nothing else on the configured network.
The .NamPoHyu Files Virus ransomware might distribute itself via different tactics. A payload dropper which initiates the malicious script for this ransomware is being spread around the Internet, and researchers have gotten their hands on a malware sample for the original variant. The website that got hit with the ransomware has not been identified to be hit by malware by most security tools as showcased in the below snapshot:
In addition, to try and get ahead of ransomware threats, you should read the ransomware prevention tips located at the corresponding forum thread.
.NamPoHyu Files Virus is a virus that encrypts files and demands a ransom via a note. The ransomware is also known as the NamPoHyu virus, but it is actually a variant of the [wplinkpreview url=”https://sensorstechforum.com/remove-megalocker-ransomware/”] MegaLocker Ransomware family. The cryptovirus uses the AES encryption algorithm by using Cipher Block Chaining (CBC) with 128-bit ciphers. That encryption is sequential (i.e., it cannot be parallelized), and the message is padded to a multiple of the cipher block size. Every block of data is encrypted by using data from the previously encrypted block, making this a chain, hence naming the encryption method CBC. AES-CBC, operates by XOR’ing (eXclusive OR) each block with the previous block and cannot be written in parallel. This affects performance due to the complex mathematics involved requiring serial encryption. AES-CBC also is vulnerable to padding oracle attacks, which exploit the tendency of block ciphers to add arbitrary values onto the end of the last block in a sequence in order to meet the specified block size. That could explain why the ransomware is set to encrypt systems in strange hours in the night, so users could be less aware of an attack.
.NamPoHyu Files Virus ransomware might make new entries in the Registry to achieve persistence, and could launch or repress processes of the operating system. Such entries are typically designed in a way to start the virus automatically with each boot of the operating system.
The ransom note message itself is located inside a file called !DECRYPT_INSTRUCTION.TXT:
The ransom note file has the following contents:
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: 02DCED685XXXXXXXXX41863What do I do ?
You can buy decryption for 250$.
But before you pay, you can make sure that we can really decrypt any of your files.To do this:
1) Download and install Tor Browser ( https://www.torproject.org/download/ )
2) Open the https://qlcd3bgmyv4kvztb.onion/index.php?id=23CAEC83B8FF4ED5A89A8E19B0D7E85C web page in the Tor Browser and follow the instructions.FAQ:
How much time do I have to pay for decryption?
You have 10 days to pay for the ransom after decrypting the test files.
The number of bitcoins for payment is fixed at the rate at the time of decryption of test files.
Keep in mind that some exchangers delay payment for 1-3 days! Also keep in mind that Bitcoin is a very volatile currency,
its rate can be both stable and change very quickly. Therefore, we recommend that you make payment within a few hours.How to contact you?
We do not support any contact.What are the guarantees that I can decrypt my files after paying the ransom?
Your main guarantee is the ability to decrypt test files.
This means that we can decrypt all your files after paying the ransom.
We have no reason to deceive you after receiving the ransom, since we are not barbarians and moreover it will harm our business.How do I pay the ransom?
After decrypting the test files, you will see the amount of payment in bitcoins and a bitcoin wallet for payment.
Depending on your location, you can pay the ransom in different ways.
Use Google to find information on how to buy bitcoins in your country or use the help of more experienced friends.
Here are some links: https://buy.blockexplorer.com – payment by bank card
https://www.buybitcoinworldwide.com
https://localbitcoins.netHow can I decrypt my files?
After confirmation of payment (it usually takes 8 hours, maximum 24 hours)
you will see on this page ( https://qlcd3bgmyv4kvztb.onion/index.php?id=02DCED685XXXXXXXXX3C0DFD0E241863 ) a link to download the decryptor and your aes-key
(for this, simply re-enter (refresh) this page a day after payment)
Download the program and run it.
Attention! Disable all anti-virus programs, they can block the work of the decoder!
Copy aes-key to the appropriate field and select the folder to decrypt.
The program will scan and decrypt all encrypted files in the selected folder and its subfolders.
We recommend that you first create a test folder and copy several encrypted files into it to verify the decryption.
Accessing the TOR link provided in the message opens up a FAQ page with some of the text included in the ransom note as seen from the below screenshot:
The ransom note of .NamPoHyu Files Virus indicates that your files are encrypted. You are demanded to pay a ransom sum to allegedly restore your files. However, you should NOT under any circumstances pay any ransom sum. Your files may not get recovered, and nobody could give you a guarantee for that. Adding to that, giving money to cybercriminals will most likely motivate them to create more ransomware viruses or commit different criminal activities. That may even result to you getting your files encrypted all over again after payment.
If a server or a computer system was infected with this ransomware and your files are locked, read on below on how you can remove the cryptovirus and what you try to potentially restore some of your files.

bonjour,
j’ai été attaqué par NAMPOHYU (Megalocker),
avec Spyhunter et Emsisoft, je me suis , à prior, débarassé du Virus, cependant le decrypter de Emsisoft ne fonctionne pas
Bonjour Jean Jacques, que se passe-t-il exactement avec le décrypteur?
