How to remove Cns ransomware and recover files

Complete tips to delete Cns ransomware and decrypt data

Cns ransomware encrypts stored files and then demand ransom payment for the decryption. During the encryption process, it appends filenames of each of the encrypted file with this pattern: [email protected] email address, victims ID and the “.Cns” extension.

For example, it renames “1.jpg” to “[email protected]=C279F237.Cns”, “2.jpg” to “[email protected]=C279F237.Cns”. As its ransom note, Cns displays a pop-up window (“info.hta”) and the “ReadMe.txt” text file.

The ransom notes inform the victims that their files have been encrypted. To get them decrypted, they need a decryption tool that they have to purchase from the crooks the infection. TO receive the payment information, they are asked to contact them via the provided email address.

Additionally, it is mentioned in the note that if there is an attempt to rename the files or decrypt them using third party is being made, this may lead to the permanent data loss. Before paying the ransom, the victims are asked to send up to five encrypted files and receive them back decrypted for free.

Most ransomware variants encrypt files using strong cipher algorithm. This makes it impossible for the victims to decrypt them without using a right decryption tool. However, this does not mean that users should contact/ pay to the crooks.

These individuals can’t be trusted. They never provide the decryption tool even if all their demands are met. Removing Cns ransomware even does not decrypt the affected files. However, this is necessary as this prevents the further files encryption and avoids more system damages in network.

For the files recovery, you should rely on alternatives you have. Existing backups could be the one. In fact, this is the best option to get the files back in the original accessible condition. The main problem is that not all users have backups available all valuable data.

In this case, you should once check if Shadow Copies exist. The automatically created backups from Windows OS sometimes left untouched during the entire process of system attack and files encryption. However, it could be deleted by the ransomware. So, other data recovery alternative you have is to rely on third party data recovery tool.

How did Cns ransomware enter my system?

Most users install malware through emails, fake software updaters, files downloaded through untrustworthy sources, Trojans and software cracking tools. Ransomware gets installed through emails when recipients open malicious attachments or a file downloaded via a received website link.

Fake software updaters infect systems by exploiting bugs/ flaws of outdated software or by installing malware instead of updates, fixes for the installed software. Malware downloads from unreliable pages install malware when users open/ execute them.

Trojans are malicious apps, especially designed to cause chain infections. Software cracking tools are used to activate legit software without paying for it. It is not legal to use such tools and they can be used to distribute malicious software.
