  • Eliminating or permanently destroying Shadow Copies.
  • Damaging the Windows hosts file.

As you can see, Chch ransomware is more than just a file-locker. It can complete a big variety of activities in order to succeed.

The distribution process of ransomware viruses

Cybersecurity experts from LosVirus.es[3] claim that ransomware infections are distributed via multiple deceptive techniques. Cybercriminals are most likely to inject malicious products into email attachments. They drop phishing emails to users' email boxes and pretend that they have come from some type of reputable organizations, e.g. banking, healthcare, shipping, etc.

A piece of advice would be not to open any clipped attachments without scanning them with antimalware software. Continuously, you should always identify the sender, check if the message is not sent from some type of rogue email address. Also, go through the email text and search for possible grammar mistakes. Be sure that reliable companies would take care that their emails are free from such misunderstandings.

In addition, ransomware viruses are distributed through software cracks that come from p2p networks such as The Pirate Bay, BitTorrent, and eMule. We recommend downloading all of your products and services only from reliable sources. Avoid any types of pirating websites and do not use any unknown downloading services.

Last but not least, there are other malware spreading sources such as malvertising, exploit kits,[4] malicious software updates, outdated products, infectious hyperlinks, and so on.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove Chch from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by 2-spyware.com security experts.

If your files are encrypted by Chch, you can use several methods to restore them:

Use Data Recovery Pro for file recovery purposes

Try using this software if the ransomware virus has locked your important files. Make sure that you perform each step as required to reach the best results possible

  • Download Data Recovery Pro;
  • Follow the steps of Data Recovery Setup and install the program on your computer;
  • Launch it and scan your computer for files encrypted by Chch ransomware;
  • Restore them.

Windows Previous Versions feature might help with data restore

If you have enabled the System Restore feature in the past, this method might allow you to recover some individual files and documents

  • Find an encrypted file you need to restore and right-click on it;
  • Select “Properties” and go to “Previous versions” tab;
  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

Using Shadow Explorer can help to recover some files

Try this tool if you are looking for an alternative to restore some of your data. However, make sure that the ransomware virus did not eliminate Shadow Copies, otherwise, you might not find this technique successful

  • Download Shadow Explorer (http://shadowexplorer.com/);
  • Follow a Shadow Explorer Setup Wizard and install this application on your computer;
  • Launch the program and go through the drop down menu on the top left corner to select the disk of your encrypted data. Check what folders are there;
  • Right-click on the folder you want to restore and select “Export”. You can also select where you want it to be stored.

Currently, there is no official decryptor available for .chch files

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from Chch and other ransomwares, use a reputable anti-spyware, such as Reimage Reimage Cleaner Intego, SpyHunter 5Combo Cleaner or Malwarebytes

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.
