Fake Hacker Screen Prank: Fool Tech-Savvy Friends

Updated 4 November 2026 · Standard formula, shown below

This guide shows you how to set up a convincing but harmless fake hacker screen to prank your tech-savvy friends. It uses a simple terminal window with scrolling text and a fake hacking sequence that looks impressive but does nothing. You’ll need a computer with a terminal (macOS, Linux, or Windows with WSL) and about five minutes.

What You’ll Need

A computer with a terminal or command prompt (macOS Terminal, Linux terminal, or Windows Command Prompt/PowerShell)
Basic familiarity with typing commands (you’ll copy-paste most)
Optional: a second monitor or a way to hide your screen quickly

Step-by-Step

Open your terminal. On macOS, press Cmd+Space and type “Terminal”. On Linux, use Ctrl+Alt+T. On Windows, press Win+R, type “cmd” and hit Enter (or use PowerShell).
Make the window full screen. Press F11 (or Cmd+Ctrl+F on macOS) to hide the menu bar and make it look more like a movie hacker screen.
Set a green or amber text color. Right-click the title bar (or go to Preferences/Properties) and change the text color to green (e.g., #00FF00) and the background to black. This instantly gives the classic “hacker” look.
Type a fake command that looks like a scan. For example, type: ping -t 127.0.0.1 on Windows or ping 127.0.0.1 on macOS/Linux. This will continuously send packets to your own computer, showing lines like “Reply from 127.0.0.1: bytes=32 time<1ms". It looks like a network scan but is harmless. Let it run for a few seconds, then press Ctrl+C to stop.
Run a fake directory listing. Type dir (Windows) or ls -la (macOS/Linux). This shows a long list of files and folders, many with cryptic names. It looks like you’re browsing sensitive data.
Use a fake “hacking” script. Copy-paste this into your terminal (it works on all platforms):
for /L %i in (1,1,50) do @echo Accessing server %i... & ping -n 1 127.0.0.1 >nul (Windows) or for i in {1..50}; do echo "Accessing server $i..."; sleep 0.1; done (macOS/Linux). This prints a stream of “Accessing server…” lines that looks like a brute-force attack.
Add a progress bar. Type ping -t 127.0.0.1 again, and while it runs, press Ctrl+Break (Windows) or Ctrl+\ (macOS/Linux) to show a stats line. Or use a simple progress bar script: for /L %i in (1,1,100) do @echo %i%% complete & ping -n 1 127.0.0.1 >nul (Windows) or for i in {1..100}; do echo "$i% complete"; sleep 0.05; done (macOS/Linux).
Make it look like you’re breaking encryption. Type openssl rand -base64 1000 (if OpenSSL is installed) to print a huge block of random characters. It looks like a decryption key stream.
When your friend walks by, act busy. Type a few random commands like whoami, netstat -an, or ps aux (macOS/Linux) or tasklist (Windows). These show system info and look like you’re probing the system.
Finish with a dramatic “ACCESS GRANTED” message. Type echo ACCESS GRANTED and hit Enter. Then lean back and say “I’m in.”

Common Mistakes

Using real hacking tools. Never download or run actual penetration testing tools like Metasploit or Nmap. They can trigger antivirus and are overkill for a prank.
Forgetting to close the terminal. If you leave the fake screen running, your friend might touch the keyboard and see the actual commands you typed. Clear the screen with cls (Windows) or clear (macOS/Linux) before they arrive.
Making it look too perfect. Real hackers don’t have perfectly formatted progress bars. A few typos or random pauses make it more believable.
Running commands that modify files. Stick to read-only commands like dir, ping, and echo. Avoid del, rm, or format.

Tips

Use a fake IP address. Instead of 127.0.0.1, use something like 10.0.0.1 or 192.168.1.1. It looks more like a real target.
Make it full screen. A full-screen terminal with black background and green text is the classic movie hacker look.
Add a sound effect. Play a low hum or keyboard clicking sound from your phone to add atmosphere.
Have a backup plan. If your friend is not impressed, quickly switch to a real task like checking email and say “Oh, I was just fixing a network issue.”
Practice the sequence. Run through the steps once before the prank so you can type without looking.

Troubleshooting

The terminal closes immediately. If you’re using a script, make sure you’re running it in the terminal and not double-clicking a file. If it closes, open a new terminal and try again.
Commands not found. Some commands like openssl may not be installed. Use ping or dir instead, which are always available.
The text is too small. Zoom in with Ctrl+Plus (Cmd+Plus on macOS) to make the text larger and more readable.
Your friend sees the actual command history. Clear the history with history -c (macOS/Linux) or delete the command history file on Windows (or just close the terminal and reopen it).
The green text is not showing. On some terminals, you need to change the color in the profile settings. Make sure you’re editing the correct profile.

Frequently Asked Questions

Is this actually hacking?

No. All commands shown are harmless and only affect your own computer. They display information or generate text but do not access any external systems.

Will this work on any computer?

Yes, as long as you have a terminal or command prompt. The exact commands differ slightly between Windows and macOS/Linux, but the guide covers both.

Can I make it look more realistic?

Yes. Use a full-screen terminal, change the font to a monospace typeface like Courier, and add a fake IP address. You can also install a terminal theme that mimics movies, but the built-in options are enough.

What if my friend knows Linux commands?

They might recognize that ping 127.0.0.1 is just a loopback test. Use more obscure commands like netstat -an or lsof -i (macOS/Linux) or tasklist /svc (Windows) to look busier.

Is there any risk of damaging my system?

No, as long as you stick to the commands listed. Avoid any command that deletes files, changes system settings, or installs software.

How long should the prank last?

Keep it under a minute. The goal is to surprise and amuse, not to bore. After you say “I’m in,” explain the joke and show them what you actually did.
