Emsisoft发布了MegaLocker和NamPoHyu Virus勒索软件的解密器,该软件一直针对暴露的Samba服务器。受害者现在可以使用此解密器免费恢复他们的文件。下载后,用户需确保具有Internet连接,然后启动解密器。启动后,浏览并选择勒索信息,解密器会尝试恢复解密密钥。勒索软件开发者声称要改变使用的加密算法,但在此之前用户仍然可以利用解密器恢复文件。

MegaLocker encrypts a victim's 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 text of the ransom note can be found below:

What happened to your files ?[出自:jiwo.org]
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$.
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 http://qlcd3bgmyv4kvztb.onion/index.php?id=[redacted hex] 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.

How can I decrypt my files?
After confirmation of payment (it usually takes 8 hours, maximum 24 hours)
you will see on this page (http://qlcd3bgmyv4kvztb.onion/index.php?id=[redacted hex] ) 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.
