You Have Been Hacked — fullscreen prank screen

Pick a scene, add your victim's name and hit start: the screen fills with a fake breach console, a fake ransomware countdown or a hacker typer. After a few minutes a friendly "relax, it's a prank" reveal ends the joke. Nothing on the computer is touched — it's just a web page.

▸ 1. choose a scenebreach console

Exit any time with Esc. A stealth link opens directly on the scene; the first click or key press makes it fullscreen (browsers require one tap first).

▸ 2. how to pull it off
  1. Pick a scene and type your victim's name — "Hello Tom." makes it land.
  2. Wait until they leave their computer unlocked and open this page (or send them the stealth link).
  3. Press Start fullscreen and walk away. The cursor disappears and the screen stays awake.
  4. Enjoy the reaction. The reveal screen appears on its own, or they press Esc.
✓ 100% harmless. This is a static web page: it reads no files, installs nothing and sends nothing about your computer. All "stolen" data, IPs and file names are randomly generated. Please don't use it to scare someone who might genuinely panic, and never on a work computer mid-deadline.

Guide — a harmless fake hacker screen, fullscreen

Three fake scenes, the victim’s name, a reveal timer, optional beeps and a stealth link. It is a joke page: it touches nothing on the computer, and Esc ends it.
1Pick a scene

Click Breach console (a glitching “YOU HAVE BEEN HACKED” dashboard), Ransom countdown (a fake “files encrypted” lock screen) or Hacker typer (any key pours out movie-style hacker text).

2Personalise it

Type an optional Victim’s name (up to 30 characters) and choose when the joke reveals itself: after 1, 3 (default), 5 or 10 minutes, or never.

3Set sound and cursor

Beeps & alarm sounds (on by default) are short tones generated in the browser. Hide the mouse cursor (on) hides the pointer; moving the mouse briefly shows “press Esc to exit”.

4Start it or share a link

Start fullscreen runs the scene right away and asks the screen to stay awake. Copy stealth link copies a URL that opens straight into the scene; the first click or key press makes it fullscreen.

5Reveal and exit

After the chosen time a “Relax — you’ve been pranked!” screen explains the joke and how to lock a screen. Esc ends the prank at any time; Close on the reveal screen does too.

The “you have been hacked” prank, explained

This page is a joke. The hacker screens are pure theatre: an ordinary web page showing random text and animations. It does nothing to the computer, and Esc ends it at any moment.

Is this actually dangerous? Will it harm the computer?

No. It is a normal web page and a joke. It reads no files, installs nothing, encrypts nothing and sends nothing about the computer anywhere. Every “stolen file”, IP address, password count and file name is random text generated on the spot, and the “webcam” and “security software” lines in the log are just words: the page never touches either. The only things it loads from the internet are a web font and a cookie-free page-view counter. Close the tab and it is completely gone.

How do I prank someone with it?

Pick a scene, type the person’s name and press Start fullscreen on their computer while it is unlocked, or send them the stealth link. The page goes fullscreen, hides the mouse (if that option is on) and asks the browser to keep the screen awake so the joke doesn’t fade. After the time you chose, the reveal screen tells them it was a prank.

How do I stop it or get out?

Press Esc. When you started it with Start fullscreen, that ends the prank and returns to the normal setup page. On a stealth link, or once the reveal screen shows, the first Esc may only leave fullscreen; press Esc again, or click Close on the reveal screen. Closing the tab (Ctrl+W or Cmd+W) always works too. The friendly “you’ve been pranked” screen also appears on its own after the time you chose, unless you set it to never.

What is the stealth link?

Copy stealth link copies a URL that opens straight into the prank with no setup screen. The link carries your settings: the scene, the reveal time, the name (if you typed one, so it is readable in the link) and whether sound is muted. Browsers only allow fullscreen after a tap or key press, so the scene first runs in the browser window and the very first click or key press makes it fill the screen. A stealth link always hides the mouse cursor.

Can I put the victim's name in it?

Yes. Type a name and the breach console greets them by name and ends its log with “[name], you should have locked the screen”, and the ransom screen addresses “their” files, with the name in the made-up file paths. Leave it blank for a generic version.

What are the three scenes?

Breach console: a glitching “YOU HAVE BEEN HACKED” title with fake exfiltration counters, a scrolling log, a proxy map that hops between cities, a hex dump and four progress bars over red code rain. Ransom countdown: a fake “your files have been encrypted” lock screen with made-up file names, an alarm every 20 seconds and a timer that runs out when the reveal is due. Hacker typer: every key press or click adds a few characters of a scripted, deliberately silly hacker monologue; press Alt three times for a big ACCESS GRANTED.

Does it work on a phone?

It runs on phones and tablets, but it works best on a laptop or desktop. On iPhone, Safari does not support fullscreen for web pages, so the scene fills the browser tab instead. Keeping the screen awake also depends on the browser supporting it.

How do I use it responsibly?

Keep it light and keep it short. Don’t use it to scare someone who might believe it, such as a person who is anxious about scams or not comfortable with computers, and don’t run it on a work or school computer where pranks like this break the rules or could set off a real security response. Stay nearby so you can press Esc as soon as the joke lands. The point is the laugh at the reveal, and the reminder to lock your screen when you walk away: Windows + L on Windows, Ctrl + Cmd + Q on a Mac.
