ChaCha ransomware
ChaCha ransomware is a file-locking and ransom-demanding threat that uses a mixture of RSA and ChaCha 20 ciphers to encrypt files

ChaCha ransomware is a file-encrypting threat that uses two different ciphers (RSA + ChaCha20) to lock targeted data. The malicious activities of this cyber threat were spotted in the first have of May this year. It is known that once files are encrypted, ChaCha virus ads an extension which contains random characters. Additionally, the ransomware virus applies 0x66116166 mark to each encrypted component. Later on, the malware bombards the computer screen with a message named DECRYPT-FILES.html. No particular details about the ransom price are given, however, the criminals urge to discuss all matters by making contact through the getmyfilesback@airmail.cc email address. 

ChaCha ransomware targets English-speaking people because it produces a message in this language. English is first in the entire world so using this type of language is the easiest for crooks to communicate with there victims. Take a closer look at the ransom-demanding message:

Removal process Scan the system with Reimage and find all infected sources on your computer 

Before you start performing the ChaCha ransomware removal process, it would be very useful and handy to download and install a reputable antimalware tool such as Reimage. Launch this tool to start the computer system scanning process, identify all infected directories and detect all malware-laden components. After you do this, take a look at the bottom of the page where you will find some data recovery measures.

ChaCha ransomware is a very dangerous and difficult threat due to the ways its activities are being carried out. First of all, this malware tricks users into opening a spam email and infiltrates the system unknowingly. After that, it uses unique encryption codes to lock files. Nevertheless, both encryption and decryption keys are stored in remote servers so that nobody, except the crooks themselves, could reach them. 

Sadly, ChaCha ransomware might be capable of even a bigger variety of activities. Some of these cyber threats are known for their capacities to destroy files' Shadow Volume Copies[1] so that the victim could not restore his/her data by using other techniques. Other file-locking viruses can inject dangerous malware and boot various malicious actions in the background.

Dealing with ChaCha ransomware virus might be hard but that does not mean that it is impossible. In order to stop the malicious activities from spreading on your computer, you need to reboot it to Safe Mode with Networking. For the future, use portable drives to store all important documents and files so that if a virus gets installed on your machine, it will not be able to reach your data.

Spreading places of ransomware-related payload

Cybersecurity experts from LosVirus.es[2] want to warn all users that ransomware-based payload can be injected in almost any kind of unsafe content. Most commonly, criminals distribute this type of malware through email spam by adding it in a harmful executable or regularly-looking hyperlink.

However, you need to be very careful with all the content that you receive in your email box. First of all, do not open any spam messages as official organizations will contact you directly. Second, use reliable antivirus software to scan all received attachments and open them only if you are 100% sure that they are safe.

Furthermore, it is very important to prevent yourself from visiting questionable networks. There are a lot of portals and domains that lack recommended protection and might include malware-related objects. Be aware of websites such as Torrents,[3] The Pirate Bay, various online gaming websites and online movie watching pages.

Elevated removal instructions for ChaCha ransomware on Windows
