How to remove CC4H Ransomware

CC4H ransomware is a hazardous type of virus that is said to be part of notorious GlobeImposter 2.0 malware family. The primary objective of this file-coder threat is to lock the important data from the infected computer in order to demand payment from victims. CC4H ransomware is using a complicated cryptographic algorithm to encrypt target files like documents, spreadsheet, presentations, archives, databases, images, photos, videos, drawings, and many more.

How CC4H Ransomware Infects the Computer?

Though CC4H ransomware came from a different family of malware, it spreads similarly like other crypto-virus as LuckyDay, Jdyi, Termit, and so on. Commonly these computer hazards are employing deceptive technique during propagation. One of the most favored methods is the use of mass-mailing technique, where attackers are able to send CC4H ransomware to thousands of email address in just a matter of time. Moreover, because these attackers amass significant amount of contact address, they can quickly deploy CC4H ransomware with ease.

Some infection cases were seen to be coming from the execution of malicious software installers that computer users may obtain from the following sources:

Dubious Freeware – Some freeware that can be downloaded from suspicious site was uploaded for the main intention of spreading ransomware like CC4H. Therefore, if downloaded and installed on the computer, the freeware gave way for the execution of CC4H ransomware attack.

Fake Software Update – Visiting malicious websites can trigger the display of misleading ads on the internet application. Some of this ads are purporting as system alert prompting to download update for famous applications like Google Chrome, Adobe Flash, on any media player. Instead of installing the software update, these tactics by cyber crooks will load CC4H ransomware onto the computer.

Cracked Programs – Just like fake software update, CC4H ransomware may also be embedded to cracked software. Some computer users are relying on pirated copies of application to run it even without proper licensed code. Aside from illegal, installing cracked applications is basis for infecting the computer with CC4H ransomware.

CC4H File Encryption and Decryption

The method that CC4H ransomware used to encrypt the file on the computer is too complex that even some experts have no capability of deciphering. Aside from the applied encryption, this ransom virus also modifies the data format by appending .CC4H file extension. Therefore, the normal image.jpg will become image.jpg.CC4H after the full encryption process. Please also note that this file extension may vary and other victims may have the CC1H, CC2H or CC3H file extension.

In order to decrypt all CC4H encrypted files, victims must pay the attackers via specified payment service that is usually process with Bitcoin currency. This is stipulated on the ransom note file with the following message.

All Your Files and Important Data Are Encrypted!
To recover data you need decryptor.
To get decryptor you should:
Send 1 test image of text file to chinarecoverycompany@airmail.cc.
In the letter, include your personal ID (look at the beginning of this document).
We will give you the decrypted file and assign the price for decryption of all files.
After we send you instruction on how to pay for decryption and after payment, you will receive a decryptor and instructions. We can decrypt one file as evidence that we have the decoder.
