Once this phase is completed, the ransomware will forward certain messages known as _readme.txt in every folder. These _readme.txt messages are more or less ransom notes sent by the rogues behind the attack, informing the computer user about what is unraveling and the need for them to pay ransom in order to receive RRBB decryption tool that would enable them recover their encrypted files.

Ransom note contents explained

The note will further draw the victim’s attention to the fact that all their crucial data including important documents, pictures, videos and all other files have been successfully encrypted following RRBB ransomware attack. Haven gotten the victim’s attention, they will attempt to open a channel of communication via electronic mails by dropping these two emails, namely; support@bestyourmail.ch and supportsys@airmail.cc. At this point, the cybercriminals would demand huge sums of money as ransom fee, usually about $980. However, in their desperation to make their victim pay without delay, they would state that half of the ransom fee being demanded i.e. $490 could be acceptable provided that payment would be made within three days or 72 hours of being notified to do so. They will also warn that if for any reason whatsoever the victim fails to pay within that time limit, then the ransom fee would have to be paid in full. To complicate matters for the victim, they would be notified that payment can only be made using crytocurrency. The obvious reason why they don’t accept other conventional methods of money transfer is to avert any chance of being tracked down by law enforcement agencies. If the victim accepts to pay the ransom fee, they would be forwarded a wallet address and also informed about the particular cryptocurrency to use in transferring it. A section of the ransom note will also suggest that any random part of the encrypted files could be forwarded to them so they could prove their expertise – but must not contain any information that could be considered as important to the victim. All these are psychological manipulations aimed at making the victim to pay the ransom fee. Regardless of their shenanigans, the FBI and diverse reputable cybersecurity experts have warned victims never to pay ransom to cybercriminals. This standpoint was recommended after they considered several factors which are listed below:

Paying ransom is never a guarantee that encrypted files would be recovered.It encourages cybercriminals by providing them huge sums of ill-gotten money.There is a high chance that such paying victim would be targeted again in the future.It might be against the law to pay ransom in your country.

Additional details regarding this ransomware attack

Following studies conducted by cybersecurity experts on different variants of STOP/DJVU ransomware, it was made known that a particular group of countries are typically exempted from ransomware attacks. The countries in this list include Russia, Syria, Belarus, Tajikistan, Armenia, Kazachstan, Krygyzstan, Uzbekistan and Ukraine. Once the virus makes a connection with https[:]//api.2ip.ua/geo.json, it will send the result to geo.json file containing vital details such as IP address, zip code, city, country, as well as longitude and latitude. If it indicates that such computer is located in any of the aforementioned countries, it would abort the mission. The dangers associated with RRBB virus goes beyond data encryption because it is also infamously known for transferring other destructive variants of malware known as Remote Access Trojans or RATs. Notable ones among them are VIDAR and AZORULT. The cybercriminals use these RATs in pilfering sensitive private data like bank account details, cryptocurrency wallets, passwords, and browsing history among others. Their target is to use them in committing further criminal acts including blackmail and theft. Victims of RRBB ransomware are advised to immediately remove the malware once they detect it in their computer. The best way to go about it is to obtain a reliable antivirus, but before installing it, the system should be booted using the Safe Mode with Networking option. In addition to that, the use of RESTORO (secure download link) is also advised to help repair damaged Windows OS files that were affected during the cyber-attack.

The Most Effective Way of Avoiding Ransomware Infiltrations

Generally speaking, illegal downloads using online torrents, opening of malicious email attachments, as well as attempting to update a computer using fake tools are the common ways through which most of these ransomware variants are distributed. Although RRBB virus and other variants of STOP/DJVU malware are typically distributed when computer users try to obtain software copies illegally by visiting online torrent platforms where pirated software contents are shared to unsuspecting computer users. Studies over the years have shown that STOP/DJVU ransomware infections are often detected after such unwholesome downloads are made. Therefore, computer users are strongly advised to stay away from such platforms and also avoid downloading/sharing of software contents using inappropriate methods. We also discovered that certain types of software contents that are in high demand are the ones cybercriminals usually pirate and use as bait in getting their victims. Some of the most ones are listed below:

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

Considering the risks involved, computer users are advised to source for all their software needs by going to the official websites of the original content producers or their authorized third-party affiliates. Also, emails should be opened with caution, especially when they emanate from unknown/unrecognizable sources. Cybercriminals are known for impersonating people/brands or even obfuscating their own address just to catch their victims unawares. The attachments they use are often created on files like DOCX, XLS or PDF. It is important for computer users to avoid opening them totally because once opened, they immediately trigger the release of ransomware on the computer they were opened. At the moment, only Emsisoft and DiskTuna have proven to be effective in helping to restore the encrypted files. Therefore, we recommend that you stay away from rogue pages promoting deceptive solutions for ransomware victims as these tools might be filled with additional malware.

Decrypt RRBB files

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

Meanings of decryptor’s messages

The RRBB 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 RRBB 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 RRBB 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.
