The "zero day" is something they call a "ClickFix Attack"

Upon Googling "ClickFix":

  > "A ClickFix attack is a social engineering technique... It typically compromises devices by manipulating victims into copying and pasting malicious commands directly into system-level tools"

I'm sorry, that's not a zero-day, that's idiocy that's as old as time.
