NOOS ransomware – the 169th Djvu family member that uses private or public keys to disable proper file access

NOOS ransomware

NOOS ransomware is the latest 169th variant of the Djvu category. This time the .noos appendix is included to each file name after locking the component by employing public or private (AES/RSA) encryption tools. Of course, NOOS virus shares the same _readme.txt note as other siblings to express ransom demands which vary between $490-$980 in BTC cryptocurrency. The first price is demanded if the payment comes between 72 hours and if the victim is late, he/she needs to pay a double amount. In addition, the users are allowed to send one file without valuable data included to cyber crooks via gorentos@bitmessage.ch, gorentoshelp@firemail.cc, or @datarestore telegram if they want to receive proof of the decryption key's existence.

Name NOOS ransomware
Type Ransomware virus/file-encrypting malware
Family This notorious cyber threat belongs to the Djvu and STOP ransomware families
Version number Since Djvu ransomware creators have been releasing new versions almost daily, NOOS virus appears to be the 169th variant
Appendix Once the malware appears on your computer, do not be surprised to see your files locked and the .noos appendix added to each document name
Cipher Criminals supposedly use encryption keys such as AES or RSA to lock up all data that is found on your computer
Ransom note  The typical _readme.txt message is also used by this ransomware virus and placed in each folder that includes locked data
Payment conditions Crooks urge for $490 in BTC if the ransom price is transferred in 72 hours and threaten to double the price if the victims pay the money in a longer time period
Spreading Ransom-demanding malware might be distributed via RDP TCP port 3389, fake FedEx/DHL shipping messages, or p2p networks such as The Pirate Bay
Identification Use antimalware such as Reimage Reimage Cleaner to locate all malware-laden strains on your Windows computer system

NOOS ransomware begins its boot-up process by carrying out different commands. The malware launches PowerShell to eliminate Shadow Volume Copies of encrypted data, prevents Windows Defender from running antivirus protection, stops the Background Intelligent Transfer Service,[1] and corrupts Windows hosts file to disable user access to security-related forums and websites where they might find a solution for NOOS ransomware removal and data recovery.

NOOS ransomware is not a threat to mess with as it might also cause secret infiltration of other malware forms. According to research, STOP ransomware variants carry an additional virus named AZORult. This is a trojan that might be distributed together with each Djvu/STOP form. Once installed, the Trojan virus might steal your passwords, access private data, swindle money from your bank account, relate to severe system and software damage.

The best decision for you here is to remove NOOS ransomware as fast as possible. This process should be taken seriously in order to delete all malicious strains that have been planted on your computer during the malware attack. First, use software such as Reimage Reimage Cleaner to discover all the malware-laden objects and then employ automatical cleaning and repair software that is capable of eliminating the ransomware infection from your Windows operating system.

If you are wondering what type of changes and processes signify about the NOOS ransomware appearance, there might be several of them. One is that your file names are changed with the .noos extension added to them. Also, you might see questionable processes running in the Windows Registry and Task Manager that allow the malware to boot up automatically and perform encryption tasks. Besides, malicious content has a chance to be spotted in these locations:

  1. %AppData%;
  2. %Temp%;
  3. %Roaming%;
  4. %Local%;
  5. %LocalLow%%.

Cybercriminals who promote NOOS ransomware urge for a hug ransom price. Our suggestion would be to avoid paying it as there is a risk of receiving no decryption software at all. Hackers are known for scamming their victims as they are only self-orientated in these types of situations. In addition, do not be threatened by claims in the ransom message that your files will be lost forever if you do not contact and pay the cyber crooks immediately:

After you uninstall NOOS ransomware from your Windows computer, you can start thinking about file recovery possibilities. Even though cybersecurity experts are currently working on the official decryptor and will release a report once the software is generated, you can take a look at the end of the article where we have provided three different data restoring methods. Pick the one that should be able to work under all conditions.

Continuously, DrWeb experts have also released a solution for those who got attacked by a Djvu malware form such as NOOS ransomware. They offer to try a decryption tool for free and if it appears to be successful for locked files, the user is advised to purchase the Rescue Pack software package for $150. Here you will get data decryption software and antivirus protections for an entire 2 years of time period.

NOOS ransomware is a file-locking threat that damages Windows hosts file to prevent users from accessing security-related websites

Distribution possibilities that are used by ransomware developers

Experts from LosVirus.es[2] state that ransomware developers think of different techniques on how to bring their beloved viruses to the surface and plant them on random computer systems. Most commonly, hackers fake to be from FedEx, DHL, or similar order shipping agencies and drop order confirmation messages to victims' email addresses.

Here you might be provided with a hyperlink that is “necessary” to confirm a shipment or with a bogus Word, Excel, or similar attachment that supposedly includes order-related information. These types of components need to be avoided and definitely not opened before scanning each one with reputable antimalware software.

In addition, RDP[3] is also known to be a way how ransomware reaches Windows computers. The TCP port 3389 is recognized as a vulnerable one which cybercriminals hack and use to brutally enter machines. Last but not least, p2p networks[4] such as The Pirate Bay also might include infectious hyperlinks with ransomware-related payload.

Necessary steps towards full computer protection against ransomware viruses

The combination of automatical and manual protection is the best way to ensure that the risk of cyber attacks decreases slightly. First of all, choose a reliable security product that will take care of your computer system and prevent various malware forms, including ransomware, from accessing your machine and its software.

Continuously, do not visit sources that force any security concerns. You should keep a distance from secondary-downloading networks, online-dating, adult-themed pages that include pornography, gambling, etc. Besides, if your AV tool marks the website that you are looking forward to visiting as unsafe, you should definitely not proceed further.

For data safety, you should always store backups of important data on at least a couple of different servers/devices. A good decision would be to purchase a USB flash drive and keep copies of valuable files there. However, remember to unplug it after usage as if you keep it connected to the computer all the time, your data might still get encrypted after a ransomware attack.

NOOS ransomware removal (automatical only)

NOOS ransomware removal is not a process to play with so you should no try to eliminate the cyber threat on your own. Instead of risking to make damaging mistakes, you should employ reliable tools to scan the system for infected locations. You can choose to install a program such as Reimage Reimage Cleaner , SpyHunter 5Combo Cleaner, or Malwarebytes.

In addition, before you start to remove NOOS ransomware, you should boot your computer in Safe Mode with Networking or System Restore just to ensure that all malicious processes have been disabled on our Windows operating system and that the malware will not boot up again automatically.

When NOOS ransomware is gone, you can try the below-provided data recovery solutions. Also, DrWeb cybersecurity firm has released a Rescue Pack for $150 that includes data recovery software and antimalware protection for 2 years which you also might find helpful.
