NamPoHyu ransomware removal instructions
What is NamPoHyu?
NamPoHyu is a new version of MegaLocker ransomware. Its developers (cyber criminals) use it to encrypt data stored on Samba servers. After a successful computer's infiltration this ransomware uses brute-force attacks to guess passwords of Samba servers that are being connected to using the infected computer. If these servers are hacked, NamPoHyu encrypts files stored on them and makes them unusable unless a ransom is paid. NamPoHyu adds the ".NamPoHyu" extension to every encrypted file (i.e. renames a file named "1.jpg" to "1.jpg.NamPoHyu" and so on), it also creates a ransom note, text file named "! DECRYPT_INSTRUCTION.TXT". Victims can find it in folders that contain encrypted data.
As stated in the ransom note, this ransomware encrypts data using AES cbc-128 cryptography algorithm. The only way to decrypt files is to pay its developers the ransom. To unlock/decrypt files victims have to send NamPoHyu's developers $250 (in Bitcoins). The price of the decryption might be changed over time. However, it is possible to check if these cyber criminals really have the tools required for a successful decryption. According to them, it can be done by using Tor browser then visiting a provided web address and following the instructions. NamPoHyu's developers promise to send the decryption tool and key after confirmation of the payment (after up to 24 hours). To download tools required for a decryption victims have to visit a website address that is provided in the ransom note. However, they will be available only if the ransom is paid. The problem is that most cyber criminals cannot be trusted, even if they say otherwise. Typically, paying them gives no positive outcome - they do not send the decryption tools as they promised and simply ignore their victims. It is very likely that that is the case with NamPoHyu's developers too. Unfortunately, most ransomware-type programs cause encryptions that are impossible to decrypt without using tools/keys that only particular ransomware's (in this case NamPoHyu's) developers have. To avoid financial loss and becoming victim of a scam we recommend to use data backup and to restore everything from there.
Screenshot of a message encouraging users to pay a ransom to decrypt their compromised data:
There are many malicious programs programs of this type out there, for example Langolier, Etols, Tellyouthepass and many others. Typically, these programs behave very similarly: they encrypt data allow their developers to demand for a ransom. Main differences usually are the price of the decryption key or/and tool and cryptography algorithm used to encrypt data. In most cases ransomware-type viruses are 'uncrackable' and their developers are the only ones who can help with the decryption. However, in some cases these encryptions can be decrypted without interference of ransomware developers, but only if these programs are still in a development state, have some bugs, flaws and so on. One way or another, to avoid data and financial loss we recommend to create data backups regularly and store them on remote server (like Cloud or other) or unplugged storage device.
How did ransomware infect my computer?

|Distribution methods||Infected email attachments (macros), torrent websites, malicious ads.|
|Damage||All files are encrypted and cannot be opened without paying a ransom. Additional password stealing trojans and malware infections can be installed together with a ransomware infection.|
To eliminate NamPoHyu virus our malware researchers recommend scanning your computer with Spyhunter.
How to protect yourself from ransomware infections?
To protect accounts from being hacked, we recommend to use strong passwords that include random characters. They should not contain details such as names, dates of birthdays and so on. To protect servers, we recommend to use a double layer of protection. In other words, to use two different passwords. We do not recommend to open attachments/links that presented in emails received from suspicious, unknown addresses. If received email is irrelevant (even if presented as important) or its sender seems to be suspicious, then the best option is to ignore it. Download software from official websites and using direct download links. Any other (third party/unofficial) tools should not be used for that. Update operating system or installed programs using implemented functions or tools provided by the official developers only. Usage of software 'cracking' tools is a cyber crime and can lead to computer infections too. And finally, we strongly recommend to have a reputable anti-virus or anti-spyware suite installed and keep it always enabled. If your computer is already infected with NamPoHyu, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.
