Questions about Nelocker ransomware virus

Nelocker virus is a noxious software example that is used to encrypt files on a target computer and demand a ransom payment. This virus is developed by the same criminal who has been working on Kovter and Miuref Trojan distribution. Lately, the criminal started delivering malware via email spam, which typically carries Label_[random numbers].zip attachment. If the victim opens this .ZIP file and double-clicks on an identically named .js file, Nemucod Trojan gets installed, and it compromises the system by launching two executable files. Now the criminal has improved Nemucod Trojan and uses 7ZIP and PHP command line utilities to encrypt victim’s data. After encrypting victim’s files, Nelocker ransomware creates a text file that explains what happened to the personal data.

ATTENTION!
All your documents, photos, databases and other important personal files were encrypted using strong RSA-1024 algorithm with a unique key.
To restore your files you have to pay 0.48307 BTC (bitcoins).

Nelocker virus

The virus employs a legitimate program 7ZIP to encrypt files on victim’s computer drives. It targets a wide range of file types, uses a randomly generated password and AES-256 encryption to corrupt data, and then sends the password to a C&C server (the same one that malware was downloaded from). Moreover, malware researchers have discovered that the Trojan downloads a PHP file and a legal PHP command line tool. In this case, Nelocker malware employs PHP command line tool to run an obscure PHP file. This file scans drivers and encrypts target files with XOR cipher. However, no matter how confusing this explanation sounds, we have some good news for you. There is a tool that can decrypt files encrypted by Nelocker ransomware. You should firstly scan the system with a tool like Reimage Reimage Cleaner Intego or SpyHunter 5Combo Cleaner and remove Nelocker virus and related malware for good. After successful Nelocker removal, start the decryption procedure.

Dissemination of this virus

Computer users should stay away from malicious emails that the author of this malware spreads via email spam. Below, you can see some examples of email attachments that the perpetrators distribute.

  • 000534364.zip
  • FedEx_ID_00000435461.zip
  • 00000875525.doc.js
  • Label_00684596.doc.js
  • FedEx_ID_00000432471.doc.js

If you receive an electronic letter from unknown individual – do not open it. As you can see, examples above show that criminals tend to hide the original .js file extension by adding a safe-looking file extension to the filename (for instance, .doc). Do not be deceived! Besides, such dangerous malware is actively distributed via exploit kits, so stay away from questionable websites, avoid clicking on ads in gambling and adult-content sites, and never explore content of emails that your email provider filters as “Spam.” Your computer system should always be guarded by an up-to-date anti-malware software, too. Creating backups is always a good idea, so create them and keep them in safe place so that you could use them in case ransomware manages to enter your computer system.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove Nelocker from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by 2-spyware.com security experts.

If your files are encrypted by Nelocker, you can use several methods to restore them:

Use Nemucod Decrypter to restore data

You can restore your files using Nemucod Decryptor. Download this tool here. To decrypt files, you need to have an encrypted copy of a file (size of at least 510 bytes) and an original copy of it. Select both files and drag them to the decrypter.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from Nelocker and other ransomwares, use a reputable anti-spyware, such as Reimage Reimage Cleaner Intego, SpyHunter 5Combo Cleaner or Malwarebytes

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. It is a hassle when your website is protected from suspicious connections and unauthorized IP addresses.

The best solution for creating a tighter network could be a dedicated/fixed IP address. If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for server or network manager that need to monitor connections and activities. This is how you bypass some of the authentications factors and can remotely use your banking accounts without triggering suspicious with each login. 

VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world. It is better to clock the access to your website from different IP addresses. So you can keep the project safe and secure when you have the dedicated IP address VPN and protected access to the content management system.

Backup files for the later use, in case of the malware attack

Computer users can suffer various losses due to cyber infections or their own faulty doings. Software issues created by malware or direct data loss due to encryption can lead to problems with your device or permanent damage. When you have proper up-to-date backups, you can easily recover after such an incident and get back to work.

It is crucial to create updates to your backups after any changes on the device, so you can get back to the point you were working on when malware changes anything or issues with the device causes data or performance corruption. Rely on such behavior and make file backup your daily or weekly habit.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware occurs out of nowhere. Use Data Recovery Pro for the system restoring purpose.
