DecYourData ransomware – a file locking virus that asks users to contact hackers for a chance of restoring personal data

DecYourData ransomwareDecYourData ransomware is a file locking virus that encrypts all personal files with AES and then demands ransom in Bitcoin for their redemption

DecYourData ransomware is a crypto-malware that was first spotted in December 2019, with a new variant appearing a month later.[1] Just as many other similar viruses of such type, it relies on file encryption process (which is performed with the help of AES[2] cipher) to hold all personal files like pictures, documents, databases, videos, PDF, and others, hostage, and demand ransom payment in Bitcoin cryptocurrency for DecYourData ransomware decryption software.

Once the DecYourData virus infection is triggered, it will scan the machine for encryptable files and provide a unique ID for each victim, which will later be used for identification, payment, and decryption process. To make sure that users know how to proceed next, malicious actors drop a ransom note “Help for decrypting id-victim ID [contact email].txt, which emails that users have to contact them via decyourdata@protonmail.com, although later version used backtonormal@tutanota.com and backtonormal@vistomail.com emails. The encrypted data is marked per the following template: id-victim ID [contact email]_all-files-encrypted. Currently, the only safe way to recover DecYourData ransomware encrypted files is by using backups, although using a few alternative methods might sometimes prove successful.

Name DecYourData ransomware
Type File locking virus, cryptomalware 
Encryption algorithm  All files are locked with the help of a symmetric AES encryption algorithm
Extension  There is no dot after the full name of the file – instead, the malware uses a space. Each of the encrypted files is appended with a particular template that consists of victim's ID and contact email; an example of an encrypted file: AfaqyStoreDataSource.xss id-42L1AP5921PZ [decyourdata@protonmail.com]_all-files-encrypted
Ransom note A template for the ransom note is also used, and includes victim's ID and email address, for example: Help for decrypting id-42L1AP5921PZ [decyourdata@protonmail.com].txt
Contact decyourdata@protonmail.com, backtonormal@tutanota.com and backtonormal@vistomail.com
Ransom size Some victims were asked to pay $5,000 in Bitcoin to recover all encrypted data

Data decryption  The only safe way to retrieve files is by using backups, although using third-party recovery software might be helpful for some victims
Malware removal To get rid of ransomware infection, scan your computer with reputable anti-malware software (for example, SpyHunter 5Combo Cleaner or Malwarebytes) in Safe Mode with Networking 
System fix Malware can cause significant damage to Windows system files. To fix virus damage and restore the registry, use Reimage Reimage Cleaner Intego repair tool

Due to relatively low prevalence of DecYourData ransomware, pinpointing its exact distribution techniques can be difficult. Nevertheless, most of file locking malware is delivered via the following methods:

  • Malicious spam email attachments or hyperlinks;
  • Pirated software installers or software cracks/loaders/keygens;
  • Poorly protected Remote Desktop (RDP) connections;
  • Exploit kits and software vulnerabilities;[3]
  • Fake updates and other executables presented on phishing sites.

As soon as the DecYourData virus breaks into a computer (it can attack all Windows versions, including the latest Windows 10), it populates various files into %TEMP%, %Users%, and other folders, one of which is typically a main executable of the malware. This file is generally used to examine particular ransomware behavior by automated sandbox tests.

Once launched, DecYourData proceeds with various system modifications, such as deletion of Shadow Volume Copies (prevents data recovery from automated backups), modification of Windows registry database (increases persistence), termination of various recovery features, etc. Due to these changes, DecYourData ransomware removal might sometimes not be successful in the normal environment, which is why experts[4] suggest users accessing Safe Mode and only then perform a full system scan with powerful security software. 

Once the preparations are complete, DecYourData ransomware proceeds with file encryption process witch appends a lengthy extension to most commonly used file types, such as .doc, .pdf, .mp4, .jpg, .dat, .mdb, .ini, etc. As a result, victims can no longer access their data, and they see a blank icon instead of an original one. Unlike most of the other ransomware, the DecYourData virus does not use the dot, which is followed by a predetermined file extension but instead replaces it with space.

After that, a brief ransom note is presented to the infected users, which states:

All your data have been locked. Want restore your data?

Fill subject with your ID like this: id-xxxxx

Email: decyourdata@protonmail.com

Most experts recommend avoiding contact with DecYourData, as well as other ransomware authors, as there is no guarantee that they will provide a decryption tool. However, because the decryptor is unique to each victim, there is little chance of recovering data without paying criminals or negating ransomware devastating effects by using backups.

DecYourData ransomware virusDecYourData ransomware is a type of virus that specializes in money extortion

If your files are encrypted by DecYourData, and you have no backups available, you should consider what is best for you. We highly recommend avoiding paying the ransom, although it might be the only choice in some cases (you should realize that you might also lose your money, however). Some victims who contacted cybercriminals claimed that they were asked to pay as much as $5,000 in BTC for decryption software.

Instead, you should copy encrypted files to an external or a virtual drive, remove DecYourData ransomware with anti-malware software, fix your Windows with Reimage Reimage Cleaner Intego or similar repair software, and then attempt data restoration via methods provided in our recovery section below.

Data-encrypting malware can be spread via various different methods

As already stated before, there are a variety of methods that cybercriminals behind ransomware viruses can use, including exploits, fake updates, spam emails, weakly protected RDP connections, etc. Some of these methods are relatively primitive, while others are far more sophisticated and complicated, and because no anti-malware software can catch 100% of the incoming computer threats, having a security program installed is not enough to protect yourself.

One of the most prominent ransomware and other malware distribution method is spam emails, where crooks clip malicious attachments or insert hyperlinks. As a general rule, malspam campaigns use popular brand names, such as Amazon, UPS, etc., although random short email messages are common too. With the help of email spoofing[5] and good social engineering skills, criminals convince users to open attachments embedded with malicious macros or click on hyperlinks that would connect to a remote server and deliver the malicious ransomware payload. Thus, please do not casually open email attachments or click on links inside, unless you are sure that the email is real.

Additional protection measure tips include:

  • Use strong passwords for all your accounts;
  • Apply security updates for all your installed applications and the OS immediately;
  • Never download pirated software installers or cracks;
  • Employ additional tools for protection, such as ad-block and Firewall;
  • Do not use the default TCP port for RDP and disconnect as soon as you are done using the feature;
  • Backup your files regularly.

Data recovery options and DecYourData ransomware removal method

Getting infected with ransomware is a tough situation to be in, as DecYourData ransomware removal would not restore all the encrypted files, despite the popular belief. It is important to realize that, once files are encrypted, only a specialized decryption tool that is stored in the reach of hackers or, in some cases, third-party software might be able to work.

Note that security researchers are also constantly working on finding bugs within the encryption process of ransomware viruses, which already resulted in successful decryptor release for multiple malware families or its versions, including BigBobRoss, Djvu, Cerber, Paradise, and many others. You can find many of such tools on the No More Ransom Project page. Thus, while there is no guarantee, it is possible that decryption software will be created for the DecYourData virus as well.

If you had no backups, you should safely copy the encrypted files over (otherwise, the files might get permanently damaged, and even a working decryptor will not be successful in its recovery), remove DecYourData ransomware by following the instructions below, and then use third-party software tools to attempt file recovery.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove DecYourData from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by 2-spyware.com security experts.

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

Data Recovery Pro might be successful in recovering encrypted files

Data recovery software does not decrypt files, but rather looks for working copies burred within your hard drive. The success rate of this process highly depends on how much you used the machine after the infection.

  • 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 DecYourData ransomware;
  • Restore them.

Make use of Windows Previous Versions Feature

This method could help you recover some files one-by-one if you had System Restore enabled before ransomware struck.

  • Find an encrypted file you need to restore and right-click on it;
  • Select “Properties” and go to “Previous versions” tab;
  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

ShadowExplorer might sometimes recover 100% of your data

In case the DecYourData ransomware virus failed to delete Shadow Volume Copies, you should be successful in all of your data recovery with tools like ShadowExplorer.

  • Download Shadow Explorer (http://shadowexplorer.com/);
  • Follow a Shadow Explorer Setup Wizard and install this application on your computer;
  • Launch the program and go through the drop down menu on the top left corner to select the disk of your encrypted data. Check what folders are there;
  • Right-click on the folder you want to restore and select “Export”. You can also select where you want it to be stored.

No decryptor is currently available

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from DecYourData and other ransomwares, use a reputable anti-spyware, such as Reimage Reimage Cleaner Intego, SpyHunter 5Combo Cleaner or Malwarebytes

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

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.
