As an IT professional those scenes never bother me. If they made it accurate for the screen it would be incredibly boring: a person sitting bathed in light from a monitor typing with a blank expression. They'd pause. Then go back to typing. Every now and they'd alt-tab over to some social media or meme site for a few minutes before sighing, maybe they toss their glasses onto the desk, inhaling deeply while rubbing their temples, then switching back to the "hacking" while muttering curses under their breath.

Instead any day I'll take the CGI animations with 1990's techno music overlayed on close-up shots of fingers on keyboards with a final triumphant smack of the ENTER key, and quick simple "beep", and the actor exclaiming "I'm in!".

Or my favourite trope from the mid to late 90's: guessing the password. But not everyone can do that; they need a hacker for that.

Amateurs!
