Usually the criminals tend to use email spam campaigns that utilize different social engineering tricks to attempt to confuse the victims into infecting themselves. Depending on the campaign the operators may use any of the following strategies:

  • Body Content Linking ‒ The hackers use links that are disguised as important sites, notifications and other scams in their messages to conceal the executable files. Once the users execute them the .H_F_D_locked virus is activated onto their machines.
