Nodera virus Removal Guide
What is Nodera ransomware?
Nodera ransomware – newly-discovered malware that aims to attack Node.JS platforms
Nodera ransomware - malware that urges for 0.04 BTC in exchange for the decryption tool
When Nodera ransomware plants itself on the computer system completely, it starts searching for encryptable files that hold specific extensions. Then, the malware executes the RSA-4096 encryption cipher and starts locking each data component found even though the cybercriminals claim in their text message that they are employing RSA 2048-bit encryption. Afterward, the ransomware will generate an extension (mostly, it will be .encrypted) and append it to each filename of the encrypted documents.
Continuously, Nodera virus pastes the ransom message named How-to-buy-bitcoins.html, in the AppData folder, which includes information on how to purchase Bitcoins for the price transfer. Also, the cyber threat will place a BAT file named Decrypt-your-files.bat, on the computer's desktop, which is the decryptor that should be executed by activating various specifications after the criminals receive their Bitcoin payment.
|Target||This dangerous cyber threat targets Node.JS servers that are running on the Windows operating system. However, if the cybercriminals develop the malware even more, it can also start functioning on other OS such as Linux and macOS|
|Encryption||The ransomware claims that the encryption process executes the RSA-2048 algorithm when it truly uses a 4096-bit cipher. When all files are locked, a random appendix such as .encrypted is added to all the filenames|
|Ransom note/price||The malicious string includes the ransom note named How-to-buy-bitcoins.html in the AppData folder where the cybercriminals urge for a 0,04 Bitcoin transfer|
|Delivery||It is known that this ransomware virus is most commonly delivered through infectious HTA files and malvertising advertisements that are met on unsecured online sources|
|Related files/folders||Files: fs.js, package.json, polyfills.js, graceful-fs.js, legacy-streams.js, ILT8PCI.js, GFp0JAk.exe, node.exe. Folders: node_modules|
|Termination||This dangerous cyber threat can be eliminated by purchasing and launching antimalware software that is capable of dealing with such advanced viruses|
|Repair software||If you have discovered any compromised areas on your Windows operating system, RestoroIntego might help you to fix them|
Nodera ransomware is a severe computer infection that has been already deeply analyzed by Quick Heal security specialists. These people have discovered the Node.JS framework that was linked to the malware. Such a specific fact was found very interesting as the misusage of such a platform is not common across threat developers.
Continuously, the cybersecurity specialists have discovered that the easiest way to get infected by Nodera ransomware is during online surfing sessions. The user can easily execute the malware by stepping on an infectious HTA file or clicking on malvertising-based advertisements that carry the malicious payload around the Internet.
Nodera ransomware is a dangerous malware form that targets Node.JS platforms on Windows computers
Slightly after that, Nodera ransomware fills the node_modules directory with the mentioned libraries that are named fs.js, package.json, polyfills.js, graceful-fs.js, and legacy-streams.js. However, the main script that is responsible for loading all ransomware-related tasks such as encryption of files is named ILT8PCI.js.
Afterward, Nodera ransomware scans all system directories instead of the C: drive for encryptable files and documents as its main targets are components that are created and included by the victim. Before the encryption process begins, the ransomware virus runs specific tasks that permanently delete the Shadow Copies of all encrypted files.
This way Nodera ransomware tries to harden the decryption process for the victims in case they try to recover some of their files by using alternative software. However, the ransom note claims that the only way to restore files properly is by purchasing the decryption tool from the cybercriminals before the software's expiry date:
Your files are encrypted! Encryption was produced by using a unique public key RSA-2048 generated for this computer. To decrypt files you need to obtain the private key. The single copy of the private key, which will allow to decrypt files, located on a remote server on the Internet. The server will destroy the key after a March 1, 2018. After that, nobody will be able to restore files … To obtain the private key for this computer, you need to send
to bitcoin address
You can easily delete this software, but know that without it, you will never be able to get your original files back. Disable your antivirus to prevent the removal of this software. When your transaction will be verified and confirmed you will receive your private key.
Our recommendation would be to decline any offers to pay the payment in order to release files from the prison of Nodera ransomware. Do not listen to the crooks' urges to disable your antivirus protection and so on. It is not worth risking to pay an inadequate amount of money as there is a big chance that you will get scammed by these hackers.
As you can see, Node ransomware developers generate unique keys for each computer they target. Continuously, both encryption and decryption codes are stored on remote servers that are reachable for the owners only. However, there still are some great alternative options that can help you to recover some data without big payments.
What you should do is remove Nodera ransomware with the help of an antimalware product that is capable of dealing with this dangerous parasite. Additionally, when you are done with the malware and it is gone for good, you should go to the end of this article where we have provided data recovery techniques some of which might allow you to restore locked files.
Nodera ransomware is a file-encrypting cyber threat that deletes the Shadow Volume Copies of encrypted data in order to harden the decryption process for the victims
You have to be extremely careful with Nodera ransomware as it might also be programmed to bring other virtual parasites up to the surface. There are some ransomware viruses that distribute other malware such as Trojan viruses and these dangerous infections can relate to permanent data loss, software corruption, identity theft, money swindling, etc.
Nodera ransomware removal should be your primary goal while dealing with this cyber threat. The process will be a complex task to complete, that is why we do not recommend trying to eliminate the virus on your own. It will likely have also placed unwanted files and entries in your Windows Task Manager, Windows Registry, and other locations.
If you are having some trouble with uninstalling Nodera ransomware from your Windows operating system, the malware might be running specific processes to block antimalware software and interrupt the removal process. For this purpose, you should reboot your computer system in Safe Mode with Networking or activate the System Restore feature.
Malvertising is a popular way of spreading ransomware viruses
Computer specialists from NoVirus.uk state that ransomware developers think of various ways how to distribute their products. One popular technique is known as malvertising. The execution of the malicious payload happens when a user steps on a malicious advertisement while browsing on an unsafe website.
Also, you might get ransomware downloaded from files and hyperlinks that you access online. A tip would be not to click on everything that looks attractive to you, avoid visiting unsecured sources, and use antivirus protection with safe-browsing.
Continuously, ransomware viruses often get delivered through email spam. Criminals pretend to be from reliable shipping organizations such as FedEx or DHL and aim to trick users by providing malicious attachments as “shipping information”. Be aware of random messages that fall into your inbox, always identify the sender, and do not open unknown files.
Furthermore, ransomware can get delivered through peer-to-peer networks such as The Pirate Bay, eMule, and BitTorrent that offer to download software cracks. These sources often get hacked and allow criminals to change the regular downloading links into ones that contain malicious products and services.

How to prevent from getting ransomware
Protect your privacy – employ a VPN
There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals.
No backups? No problem. Use a data recovery tool
If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.
If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
