Wannasmile
is the newest member of the ransomware family. This virus is a deadly infection. It sneaks into your computer unnoticed and locks your personal files. You can still see the icons of your pictures, videos, databases, music, office files, etc., but you cannot open or use them. Well, there is a slight difference in the name of the files. The Wannasmile Ransomware ads the “.WSmile” extension at the end of each encrypted file. Thus, if you have a file named example.txt, the virus will rename it to example.txt.WSmile. Following a successful installation, the ransomware scans your HDD your target files. It uses a combination of AES and RSA algorithms to lock these files. Once the encryption process is complete, the virus changes your desktop background with a black wallpaper. Your new background is the actual ransom note. Wannasmile also drops a file named “How to decrypt files.html.” It contains the same information as the wallpaper. Now, what is interesting about the note is that it is written in Persian. Basically, it explains what has happened to your files and what the demanded ransom is. The hackers ask for 20 Bitcoin (about $165164.5USD) in exchange for a decryption tool. Just for a comparison, most ransomware viruses demand about 0.5 Bitcoin. Wannasmile demands an astonishing amount of money. We must specify that this ransomware targets the business. Yet, there are also private computers which got infected with it. According to the ransom note, the victims are supposed to transfer the ransom, then to contact the crooks via email (wannasmile@tuta.io) and to wait for a reply. We recommend against such actions. The hackers are known to ignore the victims once the ransom is paid. You are dealing with cyber criminals after all. You cannot expect them to play fair. Your best course of action is the immediate removal of the virus. We recommend you to use a powerful anti-virus program. We have also provided a manual removal below this article. However, be advised. Wannasmile Ransomware is a sophisticated infection. Its removal is a bit complicated. Using an automated solution is the easiest and safest way to clean your device.

How did I get infected with?

Wannasmile Ransomware is mainly distributed via spam emails. You know how it works. You receive an email from a stranger. It looks interesting. Quite often, the scammers write on behalf of local organizations, banks, post offices and police departments. You are tempted by the received email and you open it. It states that something urgent must be done. Of course, the message contains an attached file. You, however, have heard about too many viruses to know better. Luckily, the email also contains a hyperlink which is supposed to give you more information on the matter. You click on it. Unfortunately, what you don’t know is that the hyperlinks can also be corrupted. By clicking on this link, you’ve infected your device. The crooks are imaginative. They know how to push you into impulsive actions. Before you even open an email, verify the sender. You can simply enter the questionable email address into some search engine. If it was used for shady business, someone might have complained online. Don’t stop here. When you receive letters from organizations or companies, go to their official websites. Compare the email addresses listed there with the one you have received a message from. If they don’t match, you are definitely dealing with a pretender. Delete this imposter immediately. Wannasmile Ransomware can also be distributed via torrents, bogus software updates, and malvertising. The key to a secure and infection-free computer is caution. Always do your due diligence.
