The Iranian-speaking victims are asked to pay a 20 BTC ransom to return the files with a .WSmile extension. Hackers promise to send a decryptor once they receive a letter with a transaction confirmation in e-mail address. However, we do not recommend trusting the criminals.

After the infiltration, the computer users are provided with a How to decrypt files.html ransom note, which is written in Iranian. Experts from[2] have found linkages to the ZCrypt ransomware and believe that WannaSmile virus is an offspring of the latter one. The following is the translation of the text message:

In the event that we do not receive a fee for our bitcoin-purse a maximum of 5 days after infection, then 1 bitcoin will be added daily to the original amount (20 bitcoins) . You must pay an amount of 20 bitcoins to decrypt your files, at the following address: 1KvmWVRxqw8HeFpR2tHBaoTJiTczU7PRzw

And once you pay, do not forget to send us an email to so we can send you a file from which you can restore all the files and infected systems to their original state.
