How to remove CRYBrazil Ransomware and decrypt .crybrazil or .hacked files

What is CRYBrazil Ransomware

CRYBrazil is a ransomware variant that was discovered by MalwareHunterTeam in 2018. This virus mainly targets Brazilian and Portuguese users in order to encrypt potentially important files and then demand a ransom for their decryption. While restricting access to files, the file-encryptor has been observed to assign .crybrazil or .hacked depending on what version penetrated the computer. Once the encryption is finished, CRYBrazil changes the desktop wallpapers to display decryption guidelines and also places the SUA_CHAVE.html file (which leads to a fake download page for Adobe Flash Player) in each folder containing encrypted data. This or other fake websites may therefore be used for distributing unwanted software or additional malware infections.

The text is featured in Portuguese and tells victims they have to contact extortionists via the given e-mail address (LOSALPHAGROUP@PROTONMAIL.COM) in order to return the enciphered data. Although there are no more details presented within the text, it is likely that cybercriminals will demand payment for running the decryption of files. Amounts extorted by threat actors can vary from ransomware to ransomware and range between tens, hundreds, or even thousands of dollars. Unfortunately, cybercriminals are often the only figures able to decrypt access to files completely. Decryption usually requires a unique key for each victim, which is kept secret on cybercriminals’ servers until the ransom is paid. For now, there are no free third-party tools that could be used to bypass encryption made by CRYBrazil Ransomware. The same case is common with other ransomware infections that use strong cryptographic algorithms and generate unique keys for each affected victim. The only way to recover your files is either to collaborate with extortionists and pay the ransom or restore data from external backup(s) that were not affected by the time of infection. Using your own backup is always a safer option compared to trusting extortionists – many threat actors fool their victims and do not send any decryption tools even after the payment is made. You can also ignore the decryption and not do anything if the data is not of great value to you. Note that deleting ransomware is crucial to not let it encrypt other files at the time of manual recovery. It is also important to remove it after decrypting files with cybercriminals if you decide to. Follow our guide below to do so and get protection against such threats in the future. You will also see some reputable third-party decryption/recovery software presented in our guide, however, this recommendation is general and does not guarantee the tools will successfully decrypt files blocked by CRYBrazil Ransomware.

How CRYBrazil Ransomware infected your computer

Ransomware covers a number of propagation channels that help it get settled within a targetted system – e.g., via weak/unprotected RDP configuration, phishing e-mail spam letters, trojans, deceptive third-party downloads, pirated/cracked downloads, fake software cracking tools, fake software updates/installers, backdoors, keyloggers, botnets, system exploits, and other vectors as well. To prevent various infiltrations and drive-by (stealth) installations of malware, it is advised to avoid downloading software from unofficial resources (Peer-to-Peer websites, torrent pages, landing pages, etc.) and beware of opening content that looks suspicious. For example, opening attachments or links from unknown or potentially hacked senders (be it on social media or in a dubious e-mail message) can be dangerous and thereby lead to the installation of malware. Attachments inside malicious e-mail letters or private messages sent by hacked senders may contain files like .pdf, .docx, .xlsx, .zip, .rar, .exe that might be reconfigured to deploy malware installation upon their opening. Thus, always look out for suspicious content and do not interact with it to prevent inadvertent infections.

Famous antivirus vendor Dr. Web provides free decryption service for the owners of its products: Dr.Web Security Space or Dr.Web Enterprise Security Suite. Other users can ask for help in the decryption of .crybrazil and .hacked files by uploading samples to Dr. Web Ransomware Decryption Service. Analyzing files will be performed free of charge and if files are decryptable, all you need to do is purchase a 2-year license of Dr.Web Security Space worth $120 or less. Otherwise, you don’t have to pay.

2. Back up your files

As an additional way to save your files, we recommend online backup. Local storage, such as hard drives, SSDs, flash drives, or remote network storage can be instantly infected by the virus once plugged in or connected to. CRYBrazil Ransomware uses some techniques to exploit this. One of the best services and programs for easy automatic online backup is iDrive. It has the most profitable terms and a simple interface. You can read more about iDrive cloud backup and storage here.

3. Do not open spam e-mails and protect your mailbox

Malicious attachments to spam or phishing e-mails are the most popular method of ransomware distribution. Using spam filters and creating anti-spam rules is good practice. One of the world leaders in anti-spam protection is MailWasher Pro. It works with various desktop applications and provides a very high level of anti-spam protection.
