The aim of RRCC ransomware is to make victim’s files unusable by encrypting them. This way, the data stored on victim’s computer becomes inaccessible, or in other words, taken hostage by the ransomware operators. In order to access data again, the victim has to obtain a specific decryption tool along with a unique decryption key. The cybercriminals offer to sell it for a particular price. This is nothing else but extortion, as the cybercriminals demand a ransom payment after illegally corrupting victim’s files. The crooks explain their conditions in _readme.txt ransom notes that are dropped in each computer folder respectively.
What’s explained in the ransom notes
The ransomware drops identical copies of _readme.txt file throughout the computer system. These notes explain that all of victim’s files were encrypted with the strongest encryption and unique key, and in order to recover the data, the victim has to pay a ransom. The amount of money demanded depends on how quickly the victim writes an email to the ransomware operators – if this is done within 72 hours, the crooks promise a 50% discount on the demanded amount, which would be $490 in this case. If the victim delays writing the message to the criminals any longer, they will demand $980 for RRCC decryption software and unique key required to unlock the data. The ransom note also includes two of the cybercriminals’ email addresses – support@bestyourmail.ch and supportsys@airmail.cc. The note instructs to write to these emails and insert the victim’s personal ID (a unique string assigned to the infected computer) and attach one sample of encrypted file for test decryption. This test file should not include any relevant information or the attackers might refuse to decrypt it. After contacting the criminals, victims discover that the threat actors only accept payments made using cryptocurrency. This helps to ensure that the attackers’ identities cannot be revealed or traced down by law enforcement agencies. For those wondering whether it is worth listening to the criminals’ demands, we advise checking these official FBI guidelines for ransomware victims. Paying the ransom rarely guarantees successful data recovery, besides, it helps the cybercriminals to continue their attacks and employ more people (such as malware developers and distributors).
Additional details regarding the ransomware attack
Malware analysts point out that versions of STOP/DJVU such as RRCC virus are usually distributed in tandem with dangerous information-stealing Trojans such as VIDAR or AZORULT. These threats can be controlled remotely to perform a variety of illegal actions on the compromised host, such as:
Steal browser-saved passwords, cookies and browsing history;View, delete files or download additional malware;Steal cryptocurrency wallets;Steal in-app passwords (Steam, Telegram, Skype).
Access to such information can open many opportunities for the cybercriminals to blackmail the computer user. For this reason, it is important to get rid of all malware from the computer as soon as possible and ensure it gets properly protected. We recommend you to remove RRCC ransomware virus using guidelines provided below this article. You should start by booting your PC in Safe Mode with Networking and then run your chosen antivirus solution. Afterwards, you may want to download RESTORO to initiate a system scan and identify virus-damaged Windows OS files. Then you can use this tool to repair virus damage to these files automatically.
Ransomware Summary
REPAIR VIRUS DAMAGE Files encrypted by this ransomware can be distinguished from blank icons and new extensions added to their filenames as shown in the folder screenshot below.
How ransomware-type threats are distributed
Ransomware-type threats usually await either in illegal downloads or in phishing email attachments. These distribution channels are the most common when it comes to targeting home computer users, because when it comes to attacks targeted at large companies, cybercriminals tend to use more planned and sophisticated attack methods. The vast majority of STOP/DJVU variants including RRCC ransomware virus are distributed via illegal downloads such as pirated software versions. Threat actors upload fake downloads to rogue warez sites or torrent listings claiming they’re providing “100% working free and full premium software versions” while in reality they’re spreading ransomware in disguise. Computer users who have a habit of searching for pirated software versions are at extremely high risk of infecting their computers with this ransomware strain. We always recommend visiting official software websites to download legitimate and secure copies of desired software. After all, a legitimate software license almost always cost less than the decryption tools that cybercriminals demand purchasing to recover encrypted data. Another popular ransomware distribution method relies on email spam. Cybercriminals create convincing messages accompanied by malicious attachments that usually come in popular document formats such as DOCX, PDF or XLS. The attackers often impersonate legitimate and well-known companies and claim to be sending files such as invoices, order summaries or waybills that are filled with scripts used to download and execute ransomware from an external source. If the victim falls for this bait and opens the malicious attachment, the computer gets compromised by a file-encrypting malware. For this reason, computer users are advised to practice caution when checking the email and avoid interacting with URLs or attachments sent by someone they don’t know or don’t have any kind of business interactions with. Moreover, if you can sense that the sender urges you to review attached email contents and reply soon, it is most likely a trick to make you open a malicious file. Finally, victims of ransomware should be very careful and avoid websites offering solutions for online-key encryption victims of STOP/DJVU.

Decrypt RRCC files
Fix and open large RRCC 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. RRCC 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 RRCC files, follow the given tutorial.
Meanings of decryptor’s messages
The RRCC 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 RRCC 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 RRCC 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.
