The CryptoWall ransomware has been updated to make it increasingly difficult for users to recover encrypted data.

 

The latest version of CryptoWall, version 4.0, will now alter the file names of data that it has encrypted to prevent victims from determining exactly what has been affected by the program. In addition, ransomware will now delete all system restore points upon its installation in an effort to ensure that data remains unrecoverable. If infected, the app will be accompanied by a message to victims, shown in the screenshot posted above, which states that they will be unable to recover their data unless they pay the ransom, and that any other attempt to recover data may result in irreversible loss.

In an exclusive interview to Tecmundo – a famous tech news group in Brazil -, Ondrej Vlcek, the Chief Operations of Avast, stated that the company is planning to release a security app for the platform in 2016. No specific date was given. One of the reasons is, according to Vlcek, the large number of pirate apps for Windows Phone that pretend to be official names, which collect thousands of users’ data and show an absurd amount of ads.
