Beware: CryptXXX 4.0 virus has been released!

It’s official – CryptXXX 4.0 ransomware has been released, and this time its developers have fixed flaws in its code, making the virus even more powerful. It seems that the authors of this ransomware have decided to release an even more complicated version of CryptXXX since they have lost a lot of potential income by unintentionally releasing free decryption keys for users who have been attacked by .Crypz and .Cryp1 versions of this virus. In addition to that, CryptXXX 4.0 version provides a fixed decryptor as well. Of course, the victim has to pay a certain sum of money to get it.

CryptXXX malware family contains of CryptXXX 2.0, CryptXXX 3.0, but now the fourth member has been discovered. The fourth version of CryptXXX scans the computer system thoroughly, and also all removable drives plugged into the compromised computer. No matter if these are USBs, CDs or hard drives, this malware will corrupt data stored on them as well. The encryption that this virus uses is currently the strongest one – RSA4096. The virus uses a public encryption key to encode victim’s files, and only the authors of this ransomware know what is the unique decryption code (individual for each victim). Once CryptXXX 4.0 ransomware encrypts victim’s files, it creates and saves ransom notes in .bmp, .txt and .html formats. These ransom notes inform the victim what has happened and that all files were locked with strong RSA-4096 encryption, and even provides a link to Wikipedia page about this encryption. The rest of the ransom note provides traditional decryption instructions: the user has to download Tor browser to access the payment website, buy Bitcoins and transfer them to a provided Bitcoin address. Then the victim gets a unique decryption key and can restore all encrypted data.

CryptXXX 4.0 virus leaves a threatening ransom note

If you have been infected with this virus, we would like to encourage you to not pay the ransom. Cyber criminals ask for a considerable amount of money, and by paying them, you would support their illegal activities and fund their further ransomware projects. We understand that people want to recover their files, and that is absolutely normal, but we advise you to think twice before reaching out for your credit card. If you do not want to pay the ransom, then remove CryptXXX 4.0 virus with a malware removal program, for example, Reimage Reimage Cleaner Intego. Sadly, it would be way too hard to delete this virus manually, so we do not recommend you to attempt to do that.

CryptXXX 4.0 distribution methods

Questions about CryptXXX 4.0 ransomware virus

CryptXXX 4.0 developers are advanced programmers and IT experts, and although it might sound like a compliment to them, it is sad that these guys are using their skills for such illegal activities. It seems that they spread CryptXXX 4.0 via compromised legitimate websites, which then redirects victims to Neutrino Exploit Kit. Cyber criminals exploit websites that have slightest security vulnerabilities, and it was noticed that they target pages that have added Revslider slideshow plugin (for WordPress) to them. For example, when the user clicks on a video or a slideshow presentation to start it, they will be redirected to Neutrino Exploit Kit. Cyber criminals have automated the process of scanning websites for vulnerabilities by utilizing SoakSoak botnet, which is running since 2014.

However, this ransomware still spreads using traditional malware distribution methods as well. You can get it via email, disguised as an official letter, invoice, or another document from a well-known company. Typically, crooks create email addresses that look secure and send emails to victims from them. We advise you to carefully investigate who is the sender of an email, and if you do not know it personally, do NOT open the email or its attachments.

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. It is a hassle when your website is protected from suspicious connections and unauthorized IP addresses.

The best solution for creating a tighter network could be a dedicated/fixed IP address. If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for server or network manager that need to monitor connections and activities. This is how you bypass some of the authentications factors and can remotely use your banking accounts without triggering suspicious with each login. 

VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world. It is better to clock the access to your website from different IP addresses. So you can keep the project safe and secure when you have the dedicated IP address VPN and protected access to the content management system.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
