Frequently Asked Questions

JYWD virus is a ransomware-type computer infection that aims to encrypt all files stored on the system. This harmful program is a recognized variant of STOP/DJVU ransomware. It uses .jywd extension to mark affected data, so for instance, files named 1.jpg and 2.zip will appear as 1.jpg.jywd and 2.zip.jywd following a successful attack. To inform the victim about the consequences of the cyberattack and provide instructions, the malware drops _readme.txt ransom notes in each folder.

The virus uses online/offline encryption modes to lock files on the compromised computer. It attempts to connect to its Command&Control server and obtain a uniquely generated key for the infected host. If this fails, the malware reverts to offline encryption mode and uses a hardcoded key that comes with the ransomware itself. This slightly increases the chances of decrypting data, as all offline encryption victims can recover their files with the same decryption key. You can read more on this in this guide for STOP/DJVU victims.

Unfortunately, JYWD ransomware does not only encrypt files but also infects the system with information-stealing Remote Access Trojans (RATs) known under the names of Vidar, RedLine, and AZORult. These Trojans can steal passwords, credit card details, browsing history, and other sensitive information.

The ransom note says cybercriminals want money

The ransom note created by the virus explains that all data on the computer has been locked with “strongest” algorithm, and it also claims that only the ransomware operators can restore data back to normal. The note offers JYWD file decryption tool for $980, however, it promises a 50% discount for those who contact the criminals within 72 hours after getting infected.

The note includes two email addresses that can be used to reach out to the perpetrators – support@freshmail.top and datarestorehelp@airmail.cc. The criminals also ask to include the Personal ID provided in the note when contacting them, and, if the victim wants to, they can attach one encrypted file for test decryption. The cybercriminals provide this service in hopes to encourage the victim to pay the ransom.

However, cybersecurity experts from our team do not recommend paying a ransom to cybercriminals. Doing as the criminals say may not result in the expected outcome, and your files can remain encrypted. Remember that threat actors cannot be trusted, and their sole goal is money. In addition, paying money to perpetrators allows them to fund their further operations, which leads to more malware and more victims.

If you’re someone who has been infected with this malware, we highly recommend that you remove JYWD ransomware virus using instructions provided below. Follow each step attentively and you will get rid of this threat and related malware in no time. Our team recommends using INTEGO Antivirus for malware removal task, and you may also want to download RESTORO to repair damaged Windows OS files afterward.

Typical ransomware distribution methods you should know

To avoid ransomware attacks, it is important to understand how these malicious computer programs are distributed. The criminals behind JYWD file virus usually rely on phishing emails and cracked software to infect computer users, although other methods can also be utilized. Therefore, we will overview the most common distribution methods ransomware operators use.

Phishing emails containing email attachments. Cybercriminals send thousands of deceptive emails to different recipients daily, hoping to trick them into opening an infectious URL or email attachment. They craft messages that seem to be sent by well-known companies or government institutions and invite the recipient to view attached files or URLs regarding an important matter. The attachments are usually named invoices, order summaries, waybills, notices, etc. If the recipient opens the attached file, the malicious code planted inside it launches and infects the entire computer system.

Cracked software downloads. Ransomware operators often upload deceptive installers to rogue websites and wait for victims to download them. They even set up fake crack websites to hunt for victims. Usually, popular software names like Adobe Photoshop, Illustrator, AutoCAD, Cubase, FIFA, and others are used to bait computer users into launching malware on their computers.

Exploits. Threat actors also create malicious websites designed to exploit vulnerabilities in users’ web browsers, extensions, or other applications. The user can get redirected to such sites after clicking a rogue link online.

RDP attacks. Computer users using weak RDP credentials are at high risk of getting infected with ransomware. Cybercriminals use brute-force attacks to hack into unprotected systems and plant ransomware there.

In order to avoid getting infected, computer users should avoid visiting shady online resources, keep their software and operating system up-to-date, be attentive when checking their emails and avoid cracked software. In addition, protecting the computer with antivirus software is a must.

Decrypt JYWD files

Fix and open large JYWD files easily:

It is reported that STOP/DJVU ransomware versions encrypt only the beginning 150 KB of each file to ensure that the virus manages to affect all files on the system. In some cases, the malicious program might skip some files at all. That said, we recommend testing this method on several big (>1GB) files first.

Create a copy of encrypted file to a separate folder using Copy > Paste commands.
Now, right-click the created copy and choose Rename. Select the JYWD extension and delete it. Press Enter to save changes.
In the prompt asking whether you want to make the changes as file might become unusable, click OK.
Try opening the file.

STOP/DJVU decryption tool usage guide

STOP/DJVU ransomware versions are grouped into old and new variants. JYWD Ransomware Virus is considered the new STOP/DJVU variant, just like KAAA, BGJS, BGZQ (find full list here). This means full data decryption is now possible only if you have been affected by offline encryption key. To decrypt your files, you will have to download Emsisoft Decryptor for STOP DJVU, a tool created and maintained by a genius security researcher Michael Gillespie.

Note! Please do not spam the security researcher with questions whether he can recover your files encrypted with online key - it is not possible.

In order to test the tool and see if it can decrypt JYWD files, follow the given tutorial.

Download the decryption tool from Emsisoft.
Click the little arrow next to your download and choose Show in Folder.
Now, right-click the file and choose Run as Administrator. If asked, enter administrator's password.
In UAC window, click Yes.
Click Yes to agree to software terms in both windows.
The tool will automatically include C:// disk as a location to decrypt. The file recovery tool will prepopulate the locations to scan, including connected data storage drives or network drives. Click Add folder if you wish to add additional locations.
In Options tab, you can choose to keep encrypted file copies. We recommend leaving this option selected, especially if you do not know if the decryption tool will work.
Click Decrypt to start restoring JYWD files. You will see the progress in the Results tab. Here, you can see messages from the tool, such as whether the decryption procedure is successful, or you need to wait for an update.
You might also be informed that online key was used to encrypt your files. In such case, the decryption tool won't work for you, and the only way to recover your files is to use a data backup.

Meanings of decryptor's messages

The JYWD decryption tool might display several different messages after failed attempt to restore your files. You might receive one of the following messages:

Error: Unable to decrypt file with ID: [example ID]

This message typically means that there is no corresponding decryption key in the decryptor's database.

No key for New Variant online ID: [example ID]
Notice: this ID appears to be an online ID, decryption is impossible

This message informs that your files were encrypted with online key, meaning no one else has the same encryption/decryption key pair, therefore data recovery without paying the criminals is impossible.

Result: No key for new variant offline ID: [example ID]
This ID appears to be an offline ID. Decryption may be possible in the future.

If you were informed that an offline key was used, but files could not be restored, it means that the offline decryption key isn't available yet. However, receiving this message is extremely good news, meaning that it might be possible to restore your JYWD extension files in the future. It can take a few months until the decryption key gets found and uploaded to the decryptor. We recommend you to follow updates regarding the decryptable DJVU versions here. We strongly recommend backing up your encrypted data and waiting.

Report Internet crime to legal departments

Victims of JYWD Ransomware Virus should report the Internet crime incident to the official government fraud and scam website according to their country:

In the United States, go to the On Guard Online website.
In Australia, go to the SCAMwatch website.
In Germany, go to the Bundesamt für Sicherheit in der Informationstechnik website.
In Ireland, go to the An Garda Síochána website.
In New Zealand, go to the Consumer Affairs Scams website.
In the United Kingdom, go to the Action Fraud website.
In Canada, go to the Canadian Anti-Fraud Centre.
In India, go to Indian National Cybercrime Reporting Portal.
In France, go to the Agence nationale de la sécurité des systèmes d’information.

If you can't find an authority corresponding to your location on this list, we recommend using any search engine to look up "[your country name] report cyber crime". This should lead you to the right authority website. We also recommend staying away from third-party crime report services that are often paid. It costs nothing to report Internet crime to official authorities.

Another recommendation is to contact your country's or region’s federal police or communications authority.

Frequently Asked Questions

✓ How can I open .JYWD files?

You can only open JYWD files if you have the decryption key, or if you were affected by offline encryption type.

✓ How do I know if my files were encrypted with offline or online encryption?

To figure out whether you were affected by offline encryption, please go to C:/SystemID/PersonalID.txt and see if the string inside of it ends in t1. You can also try using Emsisoft Decryptor for STOP/DJVU.

✓ My files contain very important information (family memories). Every tool I used says it is impossible to decrypt. What should I do?

Please follow the guidances provided by the official JYWD decryption tools and believe what they say. If they say it is impossible to decrypt, it really is so. There is no magic tool or human capable of decrypting your files hiding somewhere. Encryption is a technique created to be nearly impossible to decrypt without a special private key (held by the criminals).

✓ I am afraid virus is still in my computer system. What should I do?

We advise scanning with anti-virus, anti-malware, malware removal tools or software like RESTORO to eliminate virus damage on the system. If you do not trust using a single tool, try running one after another. However, we do not recommend keeping several security programs on a computer at once as they can interfere with each other's work.

✓ I saw several Youtube videos suggesting secret decryption tools. Can I trust them?

Beware of fake JYWD decryption tools circulating around the web. Cyber criminals are uploading them to various shady websites, also might be promoting them via suspicious Youtube videos. These programs can infect your computer even more heavily (Trojans, miners, etc.). We suggest being extremely cautious around the web. If there will be an official STOP/DJVU decryption tool available, it will be widely discussed in public media.
