How to remove Nanocrypt Ransomware and decrypt .ncrypt files

What is Nanocrypt Ransomware

Nanocrypt Ransomware is a new strain of ransomware that our team detected during security analyses. Much like other ransomware types, it primarily targets and encrypts files on the infected device, rendering them inaccessible to the user. After encryption, it appends the .ncrypt extension to the file names, for instance, turning document.docx into document.docx.ncrypt. The malware employs a combination of RSA and AES encryption, ensuring that without the corresponding decryption key, regaining access to the files is practically impossible. Typically, once the encryption process is complete, it generates a ransom note in a text file named README.txt. The contents of this note inform victims about the encryption, instruct them on how to purchase 50 USD worth of Bitcoin to receive the decryption tool, and caution against trying to recover the files independently or restarting the computer. This kind of manipulation is common in ransomware attacks, aimed at creating urgency and fear to coerce payment.

Despite the pressure exerted by the creators of Nanocrypt, security experts unanimously advise against paying the ransom. The reason is twofold: firstly, payment does not guarantee that the attackers will provide a decryption tool, given their primary aim is financial gain. Secondly, supporting such operations inadvertently funds and motivates further cybercriminal activities. Unfortunately, as of now, no free decryption tools are available to counteract this specific ransomware. Those affected are in a tight spot, as the complexity of RSA/AES encryption used by Nanocrypt makes it virtually unhackable without the original decryption keys held by attackers. For now, victims can explore options like consulting data recovery professionals or leveraging any pre-existing backup solutions to retrieve their data. Meanwhile, protecting devices with updated antivirus solutions, maintaining regular data backups, and exercising caution with email attachments and downloads remain the best preemptive strategies against threats like Nanocrypt.

How Nanocrypt Ransomware infects computers

Nanocrypt Ransomware infiltrates computers primarily through deceptive tactics commonly employed by cybercriminals. One prevalent method involves concealing the ransomware within pirated software, cracking tools, or key generators, which users unwittingly download from illicit sources. Additionally, attackers often exploit email phishing schemes, sending messages with malicious attachments or links that, once opened, execute the ransomware. Another avenue is through compromised websites and malicious ads that users might encounter while browsing the internet. Furthermore, vulnerabilities in outdated software can be exploited to deliver ransomware payloads, highlighting the importance of regular updates. Once executed, Nanocrypt begins encrypting files on the infected device, making them inaccessible and demanding a ransom for decryption.

How to decrypt and restore .ncrypt files

Use automated decryptors

Download Kaspersky RakhniDecryptor

Use the following tool from Kaspersky called Rakhni Decryptor, that can decrypt .ncrypt files. Download it here:

Download RakhniDecryptor

There is no purpose to pay the ransom because there is no guarantee you will receive the key, but you will put your bank credentials at risk.

Dr.Web Rescue Pack

Famous antivirus vendor Dr. Web provides free decryption service for the owners of its products: Dr.Web Security Space or Dr.Web Enterprise Security Suite. Other users can ask for help in the decryption of .ncrypt files by uploading samples to Dr. Web Ransomware Decryption Service. Analyzing files will be performed free of charge and if files are decryptable, all you need to do is purchase a 2-year license of Dr.Web Security Space worth $120 or less. Otherwise, you don’t have to pay.

If you are infected with Nanocrypt Ransomware and removed from your computer, you can try to decrypt your files. Antivirus vendors and individuals create free decryptors for some crypto-lockers. To attempt to decrypt them manually, you can do the following:

Use Stellar Data Recovery Professional to restore .ncrypt files

1. Download Stellar Data Recovery Professional.
2. Click Recover Data button.
3. Select the type of files you want to restore and click Next button.
4. Choose the location where you would like to restore files from and click Scan button.
5. Preview found files, choose ones you will restore and click Recover.

Download Stellar Data Recovery Professional

Using Windows Previous Versions option:

1. Right-click on infected file and choose Properties.
2. Select Previous Versions tab.
3. Choose a particular version of the file and click Copy.
4. To restore the selected file and replace the existing one, click on the Restore button.
5. In case there are no items in the list, choose an alternative method.

How to protect computer from viruses, like Nanocrypt Ransomware, in future

1. Get special anti-ransomware software

Use ZoneAlarm Anti-Ransomware

Famous antivirus brand ZoneAlarm by Check Point released a comprehensive tool, that will help you with active anti-ransomware protection, as an additional shield to your current protection. The tool provides Zero-Day protection against ransomware and allows you to recover files. ZoneAlarm Anti-Ransomware is compatible with all other antiviruses, firewalls, and security software except ZoneAlarm Extreme (already shipped with ZoneAlarm Anti-Ransomware) or Check Point Endpoint products. The killer features of this application are: automatic file recovery, overwrite protection that instantly and automatically recovers any encrypted files, file protection that detects and blocks even unknown encryptors.

2. Back up your files

As an additional way to save your files, we recommend online backup. Local storage, such as hard drives, SSDs, flash drives, or remote network storage can be instantly infected by the virus once plugged in or connected to. Nanocrypt Ransomware uses some techniques to exploit this. One of the best services and programs for easy automatic online backup is iDrive. It has the most profitable terms and a simple interface. You can read more about iDrive cloud backup and storage here.

3. Do not open spam e-mails and protect your mailbox

Malicious attachments to spam or phishing e-mails are the most popular method of ransomware distribution. Using spam filters and creating anti-spam rules is good practice. One of the world leaders in anti-spam protection is MailWasher Pro. It works with various desktop applications and provides a very high level of anti-spam protection.
