Researchers discovered new Virobot Ransomware that distributed along with botnet futures mainly focusing on victims based on the United States. Attackers using spam email botnet to delivery the ransomware into more number of victims and this ransomware doesn’t have a previous Ransomware family.

The experts highlighted a curiosity about the ransom note and ransom screen displayed by the malware, even if it is currently targeting users in the US, the ransom note is written in French:

Virobot Ransomware Encryption Data Process

The encryption process relies on the RSA encryption scheme, Virobot will target files with following extensions: TXT, DOC, DOCX, XLS, XLSX, PPT, PPTX, ODT, JPG, PNG, CSV, SQL, MDB, SLN, PHP, ASP, ASPX, HTML, XML, PSD, PDF, and SWP.

Or now, according to Trend Micro, the threat has been temporarily mitigated because at the time of writing the Virobot C&C server was down, meaning the Virobot’s ransomware module would not start the encryption process if it infected new victims.

Since this is a new malware strain, this is most likely because of tests that most malware distributors carry out, and it’s expected that the ransomware’s C&C servers will eventually come back for broader distribution campaigns in the future.

Virobot is also not the first malware strain that combines different components. The line between ransomware, banking trojans, keyloggers, and other malware categories has been getting murkier in past years.
