How to remove Nin9 ransomware and recover encrypted files

Tips to delete Nin9 ransomware and restore files

Nin9 ransomware is a deadly computer infection from Xorist ransomware group. It has data locking feature. It encodes all stored files, making users inaccessible to them until a ransom fee is paid. The encrypted files will receive .nin9 extension. For example, a file named “1.jpg” to “1.jpg.nin9”, “2.jpg” to “2.jpg.nin9”, and so on. After the files encryption process is complete, the ransomware drops “HOW TO DECRYPT FILES.txt” text file and drops a pop-up message and changes the desktop wallpaper.

The ransom notes provide alleged instruction to the users on how the files decryption can be done. According to this, the files recovery requires a unique decryption tool/ key and the crooks behind Nin9 ransomware are the only people who can provide this tool. Unfortunately, this is true that there is such key exist which is necessary to unlock the encrypted key and obviously the crooks are the only people who have this tool stored on their remote server. Typically, the ransomware developers ask users to contact them, transfer the demanded sum and then wait for the decryption tool to receive it.

However, in the case with Nin9 ransomware infection, the users will find no any option through which the contact is to be made. This means that the malware is at its initial stage. However, even when there is certain contact info in the form of email address or any other means, you avoid contacting/ paying to the crooks. These people will never provide you the decryption tool even if you fulfill all their demands. In such a case, the best option is to remove Nin9 ransomware and recover the files using existing backups. The malware removal is necessary to prevent further files encryption. You will find complete guide how the ransomware removal should be done just below the post.

How to recover the encrypted files?

The Nin9 ransomware removal process will do nothing to the already encrypted files. To get the files back, you can use existing backups. This could be in the form of stored data on USB drives or the cloud services. The main problem arises when the users have no such backup option available. This is the reason why security experts always recommended having a backup of all crucial data you saved on the computer. But, even when the backups are not available, there are fairly two possible options for the files recovery – first one is to use Shadow copies – the automatically created backups from OS. You will find complete guide below the post on how to recover the files using shadow copies. Another option is to use third party data recovery tools that claim to provide access to damaged, corrupted, deleted, altered files to the system.

How did Nin9 ransomware infiltrate my computer?

Usually, ransomware and other malicious malware use phishing emails, Trojans, questionable sources, channels for downloading files and programs, fake software updaters and unofficial software activation tools. It is common that the crooks send spam emails with malicious files or website links in them. The main purpose of such emails is to trick people into downloading/ opening malicious file that can be designed to infect computer with malware. The recipients infect their systems when they open the presented malicious MS Office documents, JavaScript files, executables, and archives and so on. Trojans are malicious malware especially designed to cause chain infection on already infected system.

Freeware download pages, free file hosting sites, unofficial websites, third party downloaders, p2p networks and etc can be used to proliferate to malware as well. Users infect their systems when they open the malicious files when they open malicious files that they have downloaded using those sources. The malicious files appear legit and harmless. The prime examples are fake software updaters and cracking tools. Fake software updating tools exploit bugs/ flaws of outdated software or by directly downloading malware instead of providing updates. Unofficial software activation tools cause system infection by allegedly bypassing activation keys for paid software.

How to prevent ransomware infection?

Programs and files should always be downloaded/ installed from official websites and direct links. Other sources like p2p networks, free file hosting sites and third party downloaders/installers can be and often are used to distribute malware. All installed apps should always be updated/ activated using the tools/ functions from official software developers. Most of the unofficial software activation tools and updaters are designed to distribute malware. Also, it is not legal to activate software using third party tools and use pirated software. Attachments and website links presented on any emails received from unknown sources should never be opened as well. Additionally, the system should have a reliable antivirus tool installed that provides adequate PC protection.
