CryBrazil Ransomware – Distribution
An infection with CryBrazil ransomware begins after its payload is started on a target host. The payload is usually an executable file that lands on computer systems with the help of deceptive email attachments and compromised web pages. We all receive many emails in our inbox on a daily basis. All those emails are designed to grab our attention, make us open them and interact with the elements they present. Hackers know well how to exploit human weaknesses and provoke a sense of urgency. And it appears that they often prefer to use email campaigns for the distribution of their malicious code.
By spoofing the email sender and its address, they could easily mislead you and make you believe that the email is sent by a representative of a well-known institution or business services like PayPal, DHL, FedEx, and Amazon. Hackers could also impersonate a friend or colleague of yours in an attempt to make you more prone to infect your system with the distributed ransomware.
The compromised email elements are usually file attachments presented as important documents, pictures, invoices, notifications, bills, taxes or in-text links that open a new web page in the browser. Once you got tricked into opening such an attachment on your PC or visiting the presented web page, you automatically enable the devastating malware infection CryBrazil to plague your system and data.
So next time when you need to open a dubious file on your PC you can consider the use of a free online extractor that will reveal you whether the uploaded file contains malicious elements or not. Another way to catch the ransomware on time is to scan all newly downloaded files with anti-malware tool before you open them. Once you are informed about the level of the security of a certain file you could easily refrain from opening it and this way prevent severe malware infections like CryBrazil ransomware from infecting your system.

Ele que é o palhaço, mas sou eu quem põe fogo no circo.
Todos os seus arquivos foram criptografados, para recuperá-los de volta entre em contato: LOSALPHAGROUP@PROTONMAIL.COM
The message is written in Portuguese and its purpose is to blackmail victims into contacting cybercriminals at the given email. Beware! Negotiations and contacts with hackers should be avoided. There is no guarantee that they could provide you a working decyption solution. They can try to scam you and make you a victim of their malicious intentions for the second time.
CryBrazil Ransomware – Encryption Process
Being a data locker ransomware CryBrazil primarily aims to locate specific types of files and encode them with sophisticated cipher algorithm. The algorithm known to be used by this crypto virus is AES. It is a symmetric algorithm that generates one key that is used both for encryption and decryption of data. This key is generated during the encryption stage utilized by CryBrazil ransomware. Unfortunately, immediately after encryption, the threat connects to its command and control server to deliver the key to hackers.
In case of infection with CryBrazil all corrupted files will be renamed with the extension .crybrazil. It is likely that the ransomware will encode all files that have one of the following extensions and are stored on predefined drives and folders:
→.txt, .doc, .docx, .xls, .xlsx, .ppt, .pptx, .odt, .jpg, .png, .csv, .sql, .mdb, .hwp, .pdf, .php, .asp, .aspx, .html, .xml, and .psd
The .crybrazil files will remain inaccessible until an efficient data recovery solution is applied to them.
