When Hitler is activated, a message pops up claiming: "This is the Hitler-Ransonware. (sic) Your files was encrypted! Do you decrypt your files?" It then demands payment of €25 in Vodafone mobile phone gift vouchers and gives the victim one hour to pay with a timer. If they don't, the computer crashes with a Blue Screen of Death and all files are deleted in the user profile folders.
Despite this, the files aren't actually encrypted, but a script runs to make people think it is. It is speculated that it was created only as a test as the batch file contains the words "This is a Test" in German.
A later version called "Hitler 2" was released that corrected the spelling of 'ransomware' and removed the countdown timer. A third version called "The Final Solution" was also created.
