RSA-NI virus Removal Guide

What is RSA-NI ransomware?

RSA-NI ransomware – malware that threatens to leak stolen data if the demands of the criminals aren't met

RSA-NI ransomware imageThe file-locked is targeted at companies, but regular internet users could also get infected.

RSA-NI virus infects targeted networks to make copies of important documents for the attackers. Later, the victims are asked to pay a ransom in Bitcoins to protect their data from leakage. The ransomware delivers a ransom note as Attention!!! Your data breaches!!!.txt file and its victims are addressed to contact the criminals via 0x720x730x610x30@tutanota.com and 0x720x730x610x31@tutanota.com emails.

To prevent the companies from accessing their files, the ransomware employs powerful military-grade ciphers to encode the information[1]. It is currently unknown what extension it appends following the encryption. However, due to the sophisticated algorithms used, IT experts should struggle to generate the decryption key.

name RSA-NI
Type Ransomware, file-locker, file virus
Symptoms of infection Unable to access non-system files; ransom note found on the desktop
Additional features Downloads data from infected computers/networks before encrypting them
Elimination Remove the threat with professional anti-malware software to prevent it from renewing itself
System health By using the ReimageIntego system diagnostics tool, all system irregularities will be fixed automatically so you can enjoy your device anew

Note that RSA-NI ransomware is surprisingly similar to AES-NI ransomware virus, which demands 500-1600 US dollars. Likewise, cybersecurity professionals link them to the same developers or hacker groups.

According to the malware researchers, the ransom note provides the following information:

===============================# rsa-ni ransomware #===============================
IMPORTANT: XXX and XXX

We hacked your server and copied your important data.
Please write us to the e-mail in 24 hours 0x720x730x610x30@tutanota.com 0x720x730x610x31@tutanota.com
After payment, Your data will be destroyed, Otherwise your data will be leaked to the public.

The linkage of RSA-NI ransomware virus to AES-NI virusThe ransomware threatens to leak stolen data, and experts say that AES-NI developers might have developed it.

Ransomware developers give 24 hours to make the transaction and prevent the crooks from leaking it to the public. Even though the CEOs of the companies might be desperate, we suggest you remove RSA-NI and do not encourage them to perform more cyber attacks on other businesses.

Experts from UdenVirus.dk[2] recommend performing the ransomware removal with SpyHunter 5Combo Cleaner or Malwarebytes since these are professional tools developed to deal with such high-risk computer threats. If you have another reliable security software, feel free to use it as well.

After you've successfully eliminated the malware from your device, you have to take care of its overall health. Ransomware causes a lot of damage to system files and settings, which could lead to BSoDs, freezes, and other system failures. Repair all system issues with the time-proven ReimageIntego software.

Companies receive spam emails hiding ransomware files inside

Since most of the ransomware attacks targeting businesses happen via infected emails, it is vital to raise awareness[3]. Criminals create well-designed fake letters holding the attachment with ransomware executable and send them worldwide. Usually, they try to convince people to open them by pretending to be reputable couriers like UPS or DHL.

According to our research, the emails look incredibly genuine and are named as Invoices to trick gullible people. Once clicked, the attachment enables malicious scripts and downloads the payload of the ransomware. Therefore, companies should educate their employees about the possible threats which hide inside innocent-looking emails.

Additionally, ransomware might be designed to impersonate commonly used software updates and put on peer-to-peer networks. Thus, companies are advised to avoid downloading any upgrades to their programs from unauthorized websites which might look legitimate.

Remove RSA-NI instead of enriching your assailants

Most importantly, we want to warn you not to try to remove RSA-NI manually. Ransomware is a dangerous threat to the whole system, and any attempts to get rid of it manually might cause even more damage. Therefore, stay safe and employ a certified IT specialist or follow the guide below.

The removal can be completed in 4 steps:

  1. Get Malwarebytes or SpyHunter 5Combo Cleaner from official distributors;
  2. Run a full system scan to detect and eliminate ransomware components;
  3. Repair system damages by employing the ReimageIntego system diagnostics tool;

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.
