Once the victim finds out that personal files cannot be opened, one will also notice _readme.txt notes saved in each data folder. The virus drops these in every folder containing encrypted files to store a message from the ransomware operators. These are known as ransom notes and they explain that the threat actors have taken victim’s data hostage and in order to set it free, the victim has to pay a ransom, or, as the criminals put it, purchase BBYY file decryption tool.

Ransom note explains pricing of the decryption tools

The _readme.txt file explains that even if now encrypted, files can still be recovered. In order to restore them, the victim is instructed to follow the cybercriminals’ guidelines and pay a ransom. The crooks promise to sell the victim the decryption tool and private key for $490 if the victim attempts to contact the attackers within 72 hours after being infected; otherwise, the decryption means would cost $980. The attackers also recommend attaching one encrypted file to the email and also include the personal ID string that’s provided at the end of the ransom note. The only way to contact the ransomware operators, according to the note, is via two email addresses – support@bestyourmail.ch and supportsys@airmail.cc. When it comes to ransom payments, you should know that the attackers never accept regular transaction methods and rather opt for those that are less traceable. In the majority of cases, cybercriminals tend to rely on cryptocurrency. That said, they often instruct victims to purchase the equivalent of required amount of dollars in Bitcoin and transfer it to the provided virtual wallet address. This helps to prevent law enforcement agencies, such as FBI, from tracking the cybercriminals down. Speaking of law enforcement agencies, we have to inform you that FBI as well as many cybersecurity experts advise against ransom payments. There are several reasons why people shouldn’t pay ransoms – one, it doesn’t guarantee data recovery, two, it helps the attackers to fund further operations. Finally, the cybercriminals tend to target victims who have already paid again.

Beware of additional risks associated with the malware

Victims whose computers were affected by such vicious ransomware variants such as BBYY virus should know that these tend to drop additional malware on infected systems. In simple terms, if you’re infected with this ransomware, you will also find more malware on your computer, such as VIDAR or AZORULT. Threats like these are capable of stealing various sensitive data from victim’s computer, including PC’s hardware and system information, browser-saved passwords, in-app login credentials, browsing history, cookies and more. This gives the cybercriminals many opportunities to use such information for blackmailing the victim. On top of that, these Trojans are also capable of viewing, deleting files, or downloading additional ones on unprotected system. Finally, keeping an unprotected computer increases risks of getting infected again. For this reason, we strongly recommend that you remove BBYY ransomware virus along related malware using a robust antivirus solution. Afterward, we recommend using RESTORO to repair virus damage on Windows OS files.

How file-encrypting threats are distributed

Any computer user can get infected with such notorious data-encrypting malware if one’s computer isn’t protected with a robust antivirus and also if the user has some shady habits that increase the risk of infecting the computer system. Speaking of shady habits, one of such is searching for pirated software copies or copyright-protected content online and trying to download it for free. Cybercriminals often tend to prey for unsuspecting victims in shady online websites that provide descriptions of popular software along some download links that either download a torrent file or a password-protected archive with the alleged software setup inside. Once the victim runs the provided executable, the computer system gets compromised instantly. Computer users are advised to visit legitimate software websites to download secure copies of desired computer tools. Attempts to bypass software license fees can only result in high-risk computer infections. After all, software licenses rarely cost more than decryption tools offered by cybercriminals. Another common ransomware distribution vector is malicious email spam. Cybercriminals use social engineering methods to convince the victim that the email originates from a secure source – such as well-known company or a colleague, and invites the potential victim to review attached files. Unfortunately, opening them can cause an immediate computer infection, especially if the user doesn’t have antivirus with real-time protection activated on the computer. Common lines that the attackers use to create a sense of urgency and are also often used as email subject lines are listed below:

Important! Your password will expire in 1 day(s);Your email account will be deactivated;Payment declined – Update Required;Your order has been shipped;Invoice number [random number];Problem with bank account.

That said, we advise computer users to avoid opening emails that seem at least slightly suspicious, include an unfamiliar greeting line or urge you to interact with attached contents as soon as possible. On top of that, computer users can get infected with serious ransomware variants when looking for data decryption solutions online. Since data decryption is a delicate topic and in majority of cases there are no ways to recover files without a backup, victims often find it hard to believe it. As a result, they continue to search for solutions and even wander to suspicious websites, attempting to try every solution possible. This, unfortunately, can lead to double file encryption. For this reason, we recommend you to read confirmed methods to restore/repair files locked by STOP/DJVU. At the moment, only Emsisoft and DiskTuna provide useful solutions.

Decrypt BBYY files

Fix and open large BBYY 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. BBYY 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 BBYY files, follow the given tutorial.

Meanings of decryptor’s messages

The BBYY 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 BBYY 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 BBYY 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.
