What is NEVADA Ransomware
NEVADA is a ransomware virus that encrypts data on Windows and Linux operating systems and urges victims to pay money for its decryption and non-disclosure of collected information. At the time of encrypting access to data, the virus also assigns its .NEVADA extension to affected files. For instance, a file originally named
1.pdf will change to
1.pdf.NEVADA reset its icon, and become no longer usable. Following this, the malware creates readme.txt – a text note with decryption guidelines. Cybercriminals behind NEVADA Ransomware may vary since this file encryptor is open for purchase by other malefactors (Ransomware as a service model).
Greetings! Your files were stolen and encrypted.
You have two ways:
-> Pay a ransom and save your reputation.
-> Wait for a miracle and lose precious time.
We advise you not to wait.
After 2 days of your silence we will make call your superiors and notificate them about what's happened.
After another 2 days all your competitors will be informed about your decision.
Finally, after 3 days we will post your critical data on our TOR-website.
If you are going to recover your files from backupsa and forget this like a nightmare, we are hurry to inform you - you can't prevent a leak.
-> Don't delete/rename encrypted files
-> Don't use any public "decryptor", they contain viruses.
You have to download TOR browser.
To contact with us your can use the following link:
The cat is out of the bag.
It is said victims have about 2 days to contact extortionists via the given TOR link and pay for decryption – otherwise, cybercriminals will begin measures aimed at disrupting the reputation of victims, which implies the publication of important data and informing alleged competitors. This, therefore, indicates that NEVADA Ransomware targets businesses rather than regular users. Unfortunately, cybercriminals are the only figures who can decrypt the locked data. The virus uses strong encryption algorithms (Salsa20) and also stores its keys securely on an online server, which makes manual decryption practically impossible. At the moment, the only and always viable way to return the encrypted files for free is to recover them from an available backup that was not affected at the time of infection (cloud storage, USB pen drives, external drives, etc.). The only downside of this is that cybercriminals might still publish the data as promised and indeed deal reputational damage. If you otherwise consider paying the ransom please note that there is always a risk to be fooled – some cybercriminals do not send any decryption tools to victims who eventually paid for decryption. Lastly, you can also ignore the threats and simply delete the ransomware if there is no reputational damage or data loss to worry about. Unless you are planning to pay the ransom, 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, it is less likely they will be able to decrypt .NEVADA files at this moment. Keeping encrypted files and waiting for some free third-party tool in the future may be a good idea, however, it is not guaranteed that one will be developed meaning your files may stay locked for years.
How NEVADA Ransomware infected your computer
Ransomware infections can enter your system in a number of ways – such as phishing e-mail letters, unprotected RDP configuration infected software installers (pirated or cracked), exploit kits, trojans, fake updates/license cracking tools, unreliable ads, backdoors, keyloggers, and other dubious channels. As a rule, users become infected after downloading or opening some malicious file or link, such as those found in fake emails disguised as legitimate files (.DOCX, .XLSX, .PDF, .EXE, .ZIP, .RAR, or .JS). These e-mails may impersonate reputable compines (e.g., delivery companies, tax authorities, banks, and so forth) to trick usersinto clicking harmful links or downloading malware. Interacting with content from such e-mail messages is dangerous and can lead to the installation of malware. Links attached to malvertising e-mails can lead to fake websites proposing malicious software or asking for users’ credentials. Thus, you should always avoid interacting with dubious download sources, torrent-sharing pages, suspicious ads, potentially malicious attachments/links, and other kinds of risky content. Download software only from official resources to prevent drive-by (stealth) installations of malware.

How to protect computer from viruses, like NEVADA Ransomware , in future
1. Get special anti-ransomware software
Use ZoneAlarm Anti-Ransomware
Famous antivirus brand ZoneAlarm by Check Point released a comprehensive tool, that will help you with active anti-ransomware protection, as an additional shield to your current protection. The tool provides Zero-Day protection against ransomware and allows you to recover files. ZoneAlarm Anti-Ransomware is compatible with all other antiviruses, firewalls, and security software except ZoneAlarm Extreme (already shipped with ZoneAlarm Anti-Ransomware) or Check Point Endpoint products. The killer features of this application are: automatic file recovery, overwrite protection that instantly and automatically recovers any encrypted files, file protection that detects and blocks even unknown encryptors.
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. NEVADA 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.
