Crypted ransomware might be back into the wild

Crypted virus

Crypted is a ransomware-type cyber infection that emerged in spring 2016 appending .crypted file extension to various files on the targeted computer. However, in November 2017, computer users reported about data being locked with .crypted_uridzu@aaathats3as_com extension. Malware researchers assume that criminals created a new, undecryptable version of the malware. Though, this crypto-virus is still under investigation.

Crypted virus is also known as Nemucod ransomware[1]. However, the file extension that it originally appends is also used by PyCL ransomware virus. When audio, video, music, images, documents, and other necessary files are encrypted, malware drops a ransom note.

Ransom-demanding instructions are delivered in two files – Decrypt.txt or Decrypt.hta. They state that that victim’s files were encrypted and that one needs to buy a private decryption key[2], which can be used for data decryption.


Just like any other ransomware, Crypted Trojan commands to use The Onion Router, also known as TOR software and make the payment in Bitcoins.[3] However, if you are a victim of this ransomware, we recommend you to think about Crypted removal instead of paying the ransom because:

  • First of all, you can never know if cyber criminals will actually provide the decryption key, or if they just want to steal your money;
  • Second, think if you want to support cyber criminals in such way. The more ransoms they gather, the more motivation they get, therefore, it encourages them to continue their fraudulent activities;
  • Finally, in this case, you can recover your files without paying the ransom!

Questions about Crypted virus

Crypted ransomwareCrypted ransomware is a version of Nemucod and it locks files in order to receive a ransom. Usually, the virus leaves Decrypt.txt file on victim's computer - it is a ransom note that contains a message from cyber criminals.

.crypted files can be restored for free

Nevertheless, the majority of ransomware viruses are undefeatable, and there is no way to restore files unless authors of the malware reveal decryption tool. However, in case of .Crypted ransomware attack, malware researchers have good news. There's a free decryption tool[4] that can restore files with .crypted extension. You can find full data recovery instructions in the guide presented below virus' removal instructions.

To remove Crypted virus, we recommend using Reimage Reimage Cleaner Intego or another trustworthy malware removal tool. It is not recommended to play with this ransomware and attempt to remove it manually unless you know what you're doing. If you lack knowledge about computer viruses, please do not try to uninstall this virus manually.

IMPORTANT NOTE. Please remember that .crypted file extension virus differs from .encrypted file extension virus. The latter extension is used by many different ransomware viruses such as CryptoLocker, Keranger and Crypren

Ransomware mostly spreads via malicious spam emails

Crypted malware usually spreads via infectious emails: the cyber criminals send fake emails that contain attachments. It is vital to check if you know the sender of email before you open it or its attachments. Usually, frauds pretend to be delivering relevant documents, for example, invoices, price charts, bills, resumes and so on.

Be careful when dealing with such emails. In addition, stay away from Spam/Junk folders as many fraudulent emails do not pass these email security filters and fall into these categories. 

You should be attentive when browsing the Internet as cyber criminals tend to spread malicious files and programs by concealing malicious links in some websites. Try to avoid visiting suspicious websites, and refrain from clicking on intrusive pop-up ads or banners.

Also, avoid downloading files from insecure file sharing networks. You might install Trojan horse on your computer without even knowing it; reportedly, a trojan named JS.Nemucod spreads this ransomware, as well as other well-known viruses, such as Locky, Teslacrypt, KeRanger, and others.

Nemucod Trojan mostly proliferates via email in a form of malicious JavaScript file. Of course, this JS file is crafted to look safe, so inattentive users can open it without realizing how dangerous it actually is. For this reason, some security researchers[5] identify Crypted as Nemucod ransomware.

Crypted ransomware removal and date recovery

Crypted removal is a hard process. The ransomware is a complicated and well-constructed virus, which hides its components deeply in the computer system. Moreover, components of such viruses use safe-sounding names, which makes it harder to identify them.

For this reason, we recommend you to install a professional malware removal tool and terminate all programs and processes related to it. We recommend using Reimage Reimage Cleaner Intego or another top-rated malware removal software. In case you wish to remove Crypted virus but your anti-malware software won't start, follow these instructions that will help you to prepare your computer for malware removal.

Bonus: Recover your data

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

If your files have been encrypted by the discussed virus, do not even think about making the payment. Malware researchers have already discovered a method how to crack this ransomware and developed Crypted decryption software. You can find instructions how to use it below.

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

Try Data Recovery Pro software

In case the suggested decrypter doesn't help you to recover your files, you can give Data Recovery Pro a try. This data recovery software is known to be effective when dealing with corrupted or deleted files.

  • Download Data Recovery Pro;
  • Follow the steps of Data Recovery Setup and install the program on your computer;
  • Launch it and scan your computer for files encrypted by Crypted ransomware;
  • Restore them.

Use .crypted decryption software to set your files free

To recover your files, download this program – Crypter decryptor, and then find two files – the original one and encrypted version of it. You can use any file you want, and the easiest way is to use sample photos that are stored in My Pictures folder.

Once you have the two files, select both of them and drag them to the icon of the decryptor you have just downloaded and release. The decrypter then brute-forces the key, which is required for data decryption. 

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from Crypted 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 from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
