Frequently Asked Questions

EIJY ransomware is a malicious computer virus designed to encrypt all files on computers and then extort their users. This virus belongs to the STOP/DJVU ransomware family. Its operational method is in this format; infect a computer, encrypt files contained in it, and also append .eijy extension to all the file names. For example, let’s assume that files stored in a computer were named 1.jpg, 2.jpg and so on prior to it being infected with the virus. Afterwards, they would automatically become 1.jpg.eijy, 2.jpg.eijy etc. Coupled with that is a message sent by the cybercriminals known as _readme.txt. It contains information notifying the victim about what has occurred and why they must fulfill their demands so they could be given EIJY decryption tool that would reverse the encryptions.

This ransomware is part of a malware family known as STOP/DJVU – the same online rogues that have been threatening computer users across the globe since 2018. There is no doubt about the potency of this virus or the intentions of those circulating it, as it has been confirmed to be a highly destructive tool being used by cybercriminals to seize control of other people’s files for extortion purposes.

The virus drops a ransom-demanding note

Although the victim may have already noticed their computer no longer functions properly and would be wondering if it has been infected by some virus, the message contained in the _readme.txt will clear all doubts. Depending on how important the data collected in the computer is, the victim may become desperate to try to retrieve them, especially if there are no backup copies available. Already anticipating such, the cybercriminals would also forward two email addresses, namely; support@bestyourmail.ch and supportsys@airmail.cc.

In addition to that, they will also list their price and conditions that have to be met during payment. To influence the victim and make them pay quickly, they will state that a 50% discount on the ransom fee could be given to them, thereby bringing it down to $490. However, if the victim fails to make payment within a maximum of 72 hours or 3 days, the discount offer would become nullified, and the full payment of $980 would become mandatory.

As if that wasn’t enough trouble, they will also insist that payment can only be made with cryptocurrency that would be transferred to any wallet of their own choice. The apparent reason why they avoid other payment methods is simply to prevent investigators from detecting their identity or location. To gain the confidence of the victim that they genuinely have the capacity to decrypt their files, they may at this point request that samples of the corrupted files be sent to them for test decryption. However, they would also add that returning the result would be at their own discretion if they consider the file to be of less importance to the victim.

Regardless, a memo released by the FBI warns that ransom should not be paid to cybercriminals no matter the pressure. This advice is also supported by other influential security organizations. Some of the reasons given by them for taking this stand include the following:

There is no assurance you will recover your encrypted files even after paying huge sums as ransom.
You indirectly support criminality by making it profitable to those involved in it.
When you pay the ransom, you make yourself vulnerable to future extortions.

The specifics of this ransomware variant

From our studies, we discovered that a number of countries were designated as “protected from a ransomware attack”. The countries are Ukraine, Russia, Belarus, Syria, Uzbekistan, Kazachstan, Kyrgyzstan, Armenia, and Tajikistan. To ensure that computers located in these countries are not affected by the STOP/DJVU ransomware, the malware was configured to be able to detect the geo-location of computers and would also make a connection with https[:]//api.2ip.ua/geo.json so that vital details like IP address, city, zip code and country, as well as longitude and latitude. These pieces of information are what would signify if the attack should continue or not.

The malware is also known for spreading other Trojans, generally called RATs or Remote Access Trojans. The RATs are used by cybercriminals to steal crucial personal information such as cryptocurrency wallets, passwords, banking details, software logging credentials, etc. Access to such information would enable them to engage in other forms of fraudulent activities.

It is very important for victims of STOP/DJVU ransomware to get rid of it as quickly as possible to avert further damage. The best way to remove EIJY ransomware is to boot your computer using the Safe Mode with Networking option. Afterwards, genuine antivirus software should be installed on the computer. The use RESTORO is also recommended to help repair some of the damaged Windows OS files.

How to Protect Your Computer From STOP/DJVU Ransomware

Cybercriminals exploit different means in spreading malware to as many computers as possible. The most common ones are by embedding them in cloned key generators and pirated game or utility software that are often uploaded on online torrents sites, and also by sending out malicious emails/attachments. Therefore, it is essential to avoid online torrents platforms, sharing of software contents illegally, as well as opening of emails and attachments you’re not fully of its genuineness or intentions.

Information gathered over the years shows that cybercriminals often clone/pirate popular software content that are in high demand. These fake software contents are what they use as bait in getting computer users that are desirous of freebies.

Here is a list of popular software copies often pirated and used by cybercriminals in spreading ransomware:

AutoCad;
Cubase;
Adobe Illustrator/Photoshop/Premiere Pro;
Corel Draw;
Internet Download Manager.
Tenorshare 4ukey;
VMware Workstation;
League of Legends.

It may appear attractive to download needed software copies in online torrents platform, but when you consider the accompanying risk of ransomware attack, then you will agree it’s not worth it. Also, remember that these software copies required time, resources, and investments to develop, thus it becomes unfair to deny the genuine producers a reward for their efforts.

Aside the use of cloned software, cybercriminals equally make use of emails and attachments in spreading malware. They will either impersonate brands or individuals in order to take their target audience unaware. By making use of files like DOCX, PDF or XLS among similar others that enable macro functions, they will be able to embed malware and trigger it when opened in any computer. It is imperative not to open emails and attachments from unknown sources, has its address spoofed or contains obvious typo errors.

If you’re already a victim, you shouldn’t panic and start engaging online adverts that claim to provide decryption solutions because most of them are not genuine and could put you in further trouble. Since last time we checked, only Emsisoft and DiskTuna brands have proven capable of restoring encrypted files.

Decrypt EIJY files

Fix and open large EIJY 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 EIJY 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. EIJY Ransomware Virus is considered the new STOP/DJVU variant, just like BBYY, BBII, BBZZ, BBII, HKGT, EFVC, EIJY (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 EIJY 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 EIJY 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 EIJY 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 EIJY 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 EIJY 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 .EIJY files?

You can only open EIJY 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 EIJY 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 EIJY 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.
