They will emphasize that EYRV ransomware virus has successfully encrypted all the files contained in the infected computer, including documents, pictures, data etc. Therefore, they have no other choice than to comply with the ransom payment since they made use of very strong encryption key that can’t be breached. To open a channel of communication, they will equally drop two email addresses, namely: support@sysmail.ch and supportsys@airmail.cc, to enable the victim respond to them. Other information contained in the _readme.txt file includes decryption prices as well as terms and conditions attached with the payment. They will point out that paying without delay will make it possible for the victim to pay only 50% of the ransom fee which amounts to $490. However, once the 3 days window period elapses, only the full ransom fee of $980 must be paid by the victim. Peradventure the victim decides to respond to them using any of the emails they dropped; they will state that payment can only be made by purchasing cryptocurency that is worth the ransom fee and transferring it to a wallet address that would be made available for the purpose. They obviously use such anonymous payment method in order to protect their identity and avoid possible arrest by the authorities. To convince the victim of their ability to restore their files, they would suggest for excerpts of it to be sent to them for test decryption. Whatever happens, the general advice by our team of experts is that victims should adhere to FBI’s guidelines regarding ransom issues and the bottom-line is that ransom must not be paid, no matter what. The reason is because paying ransom does not guarantee that decrypted files will be restored by the cybercriminals and moreover, doing so would only make more funds available to cybercriminals which would enable them to expand their criminal activities and victimize more people. Globally, cybercriminals extort millions from their victims annually and this situation can only be stopped or minimized to the barest minimum when victims stop paying ransom. Also of concern is the fact that information-stealing Trojans like AZORULT and VIDAR are usually released as secondary virus to steal vital information such as banking details, software account details, cryptocurrency wallets, passwords, and browsing history among others which they could also use to perpetrate further criminal acts. Victims of this STOP/DJVU malware variant are advised to remove EYRV ransomware from the PC as soon as possible to avoid further damage. This can be done setting up your computer in Safe Mode with Networking option before scanning a strong antivirus software on it. However, it is crucial to make use of only genuine antivirus software and if you’re not of which brand to use, then you can always avail yourself INTEGO Antivirus because it has been proven to be very reliable. Additionally, we recommend scanning with RESTORO (secure download link) to repair virus damage on Windows OS files.

Ransomware Summary

REPAIR VIRUS DAMAGE

Ransomware distribution techniques to be wary of

The most common way computer users infect their PC with STOP/DJVU variants including EYRV virus is when they download software contents from malicious online torrents. Cybercriminals often embed malware in pirated software contents; therefore trying to make use of fake key generators and so-called “cracks” downloaded from such platforms is dangerous and can lead to severe malware infection. Over the years, victims have reported of ransomware attack after downloading certain software copies and the common ones mostly used by cybercriminals in distributing ransomware through online torrent libraries are listed below:

Internet Download Manager;Adobe Photoshop;Tenorshare 4ukey;AutoCad;Opera browser;Corel Draw;VMware Workstation;Cubase;Adobe Illustrator;League of Legends;Fifa 20;KMSPico (illegal Windows activation tool).

For those that have a tendency of searching online torrents for software copies to download, you should know that such habit is dangerous and is putting you at serious risk of cyber-attack. The old phrase “penny wise, pound foolish” holds true here because in trying to avoid paying a token for your software needs, you may end up paying outrageous fees as ransom to cybercriminals when you eventually become a victim. Besides, when you download pirated software contents from malicious online torrents, you’re indulging in copyright infringement and such activity is a punishable offence by law. On the contrary, we recommend that software contents should only be sourced from the official pages of the original content developers or their third-party affiliated partners. By so doing, you won’t be at risk of ransomware attack; losing your money, time and important files. Another method of distributing ransomware used by cybercriminals is through malicious email attachments, whereby they would compose highly believable email messages alongside customized attachments, using formats such as DOCX, PDF and XLS among similar ones. They prefer these particular ones because they enable macro functions and JavaScript that are required for download of payload and also to trigger it in diverse random computers. Lastly, for those that have become victims of STOP/DJVU ransomware already, it would be in your best interest to avoid certain dubious websites that claim to offer decryption services because they’re mostly crooks trying to spread other versions of ransomware. Downloading such fake tools could lead to double file encryption and loss of sensitive information.

More details concerning the virus

For those that may want to know more about what happens during EYRV ransomware attack and the extent to which their computer was affected, this section would come handy. The first action the malware takes is to launch build.exe or build2.exe executables as well as winupdate.exe (which displays fake Windows screen). Once that is done, it will connect to https[:]//api.2ip.ua/geo.json and save the response to geo.json file. Afterwards, it will begin information gathering of every detail concerning your computer and would store them in its geolocation-related database and would contain the infected computer’s geolocation, time zone, zip code, as well as longitude and latitude details. The image below shows examples of the geo.json file. It will also save names of active processes on the computer, installed software list and hardware details into information.txt file as shown below. At this point, the virus will profile the computer’s country code against a list of countries they designated as encryption-exempted, namely: Russian Federation, Ukraine, Belarus, Syria, Armenia, Tajikistan, Ukraine, Kazachstan, Kyrgyzstan, and Uzbekistan. If it confirms that the computer is located in any of the aforementioned countries, it will automatically stop any further action. However, if otherwise, the ransomware will extract online encryption key from their server and would merge it with the victim’s ID before saving it in bowsakkdestx.txt file and also save the ID separately to PersonalID.txt file. Shown below are examples of these files. If on the other hand, the virus fails to extract an online encryption key, it will resort to the use a hardcoded offline key. The remarkable difference between both keys is that online version is unique to every victim while the offline version is uniform for all. You can detect if an offline key was used if you observe the appearance of t1 characters suffixed at the end of the personal ID. Also, the use of offline key offers an advantage to the victim because there is a high chance that .eyrv files could be decrypted going forward. For more information about this, please check below the article. The ransomware will now commence with full data encryption procedure by scanning every folder and encrypting it with Salsa20 before locking it with RSA-2048 key. While the process is still going on, the virus will mark files with additional extension. Shown below is screenshot of compromised data folder. Here is a screenshot of _readme.txt ransom note that is dropped by the cybercriminals. Before concluding the attack, the virus will blacklist certain domains in the Windows HOSTS file as well as map them in localhost IP, thus effectively barring the victim from having access to them. Any attempt by the victim to browse them may bring up DNS_PROBE_FINISHED_NXDOMAIN error message. The cybercriminals go to this extent just to ensure that the victim does not get any support from online forums that offer help to victims of cyber-attack.

Decrypt EYRV files

Fix and open large EYRV 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.

STOP/DJVU decryption tool usage guide

STOP/DJVU ransomware versions are grouped into old and new variants. EYRV Ransomware Virus is considered the new STOP/DJVU variant, just like BPTO, ISWR, ISZA, BPSM, ZOUU, MBTF, ZNSM (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 EYRV files, follow the given tutorial.

Meanings of decryptor’s messages

The EYRV 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 EYRV 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.

Victims of EYRV 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.
