WannaSmile Ransomware

WannaSmile Ransomware Description

Type: Trojan

The WannaSmile Ransomware is an encryption ransomware Trojan that was first observed on November 16, 2017. The WannaSmile Ransomware is a variant of zCrypt and looks like to be targeted towards computer users in Farsi speaking regions. Variants of the WannaSmile Ransomware have been traced back to June 2016, and the WannaSmile Ransomware is just the latest in a family of threats that has been used to target computer users. The WannaSmile Ransomware is being delivered to victims through the use of spam email messages that include corrupted email attachments or embedded links. When the victim opens the attached or embedded content, the WannaSmile Ransomware is downloaded and installed on the victim's computer.

The Smile that will Never Appear on Affected Computer Users

The WannaSmile Ransomware, like most ransomware Trojans, is designed to encrypt the victim's files using a strong encryption method. This essentially allows the WannaSmile Ransomware to take the victim's files hostage. The victim then is forced to pay a large ransom in exchange for the decryption key needed to restore the affected files. The files encrypted by the WannaSmile Ransomware attack are marked with the file extension '.Wsmile.' The WannaSmile Ransomware's name seems to be a reference to the WannaCry Ransomware Trojan, which received quite a bit of attention due to the high number of victims of this attack. However, there is no connection between the WannaSmile Ransomware and WannaCry.

The WannaSmile Ransomware's Ransom Demand

The WannaSmile Ransomware delivers its ransom note after encrypting the victim's files. To do this, the WannaSmile Ransomware will change the infected computer's desktop image into a black screen with a text written in Farsi. The WannaSmile Ransomware also will deliver a file named 'How to decrypt files.html' to the infected computer's desktop. The full text of the WannaSmile Ransomware's ransom notes and messages in the original Farsi reads:
