Screen recording is a wonderful teaching tool, but the same idea, letting someone see your screen, is also used by fraudsters. A screen sharing scam usually starts with a friendly call and ends with an empty wallet, because the caller watches your OTP or PIN arrive on screen.
This post explains how these scams work, the red flags to watch for, and the simple habits that keep your codes and passwords safe, whether you are being targeted or just recording your own tutorial.
How a screen sharing scam works
The pattern is similar almost everywhere, including Bangladesh and the rest of South Asia:
- The hook. Someone calls or messages claiming to be from your bank, a mobile wallet, a delivery company or tech support. They say your account is blocked, you won a prize, or a refund is waiting.
- The request. They ask you to install a "support" app, open a screen sharing link, or start a video call and share your screen.
- The trap. While they watch, they ask you to open your banking or wallet app "to verify". Or they trigger a login and wait for the OTP to appear in your notifications.
- The theft. They read the code or PIN off your screen and use it within seconds.
Sometimes they skip screen sharing and simply ask you to send a screen recording or screenshot "as proof". The goal is the same: to see what should stay private.
Red flags you should never ignore
- Anyone asks you to share your screen, install a remote-control app, or send a recording of your banking app.
- Anyone asks you to read out, type or forward an OTP. A real company never needs your OTP.
- There is pressure and urgency: "your account will be closed in 10 minutes".
- The caller already knows a little about you, which makes them seem trustworthy. Basic details are easy to find; this proves nothing.
- You are told to keep it secret from family or the bank branch.
Protect yourself when you record your own screen
Scams are not the only risk. Honest creators also leak codes by accident. If you make tutorials, follow these habits:
Silence notifications first
OTPs usually arrive as notifications. Turn on Do Not Disturb before you record so codes never slide onto the screen. On most phones it is a tile in quick settings. Our guide to screen recording without notifications covers the common brands.
Never type a real password on camera
Many keyboards briefly show each letter as you type. Even dots can reveal the length of your password. Log in before you start recording, or pause the recording while you log in. Cinematic Recorder's floating controls let you pause and resume from any app.
Use test accounts for money apps
For bKash, Nagad or banking tutorials, use a demo or test account wherever possible and never show a real balance. Read how to record a mobile banking tutorial safely before you start.
Check the recording before sharing
Scrub through the full video. If a code, PIN or password field is visible, cut that part. Then change the password anyway if you are not sure. For more ideas, see how to hide personal information in videos.
Why some apps show a black screen
You may notice that banking and wallet apps often appear black in screen recordings or screenshots. That is a deliberate security feature: the app tells Android not to allow capture. It protects you from exactly the scams above. We explain it in why apps show a black screen when recording.
Do not try to bypass it. If you need to teach how such an app works, use the official demo, screenshots from the provider, or draw the steps on paper instead.
How Cinematic Recorder keeps your data private
Cinematic Recorder records only when you start it, and shows clear floating controls while recording. Your videos stay on your phone; we never upload them. If you choose to use AI with your own key, that key is stored in Android Keystore and is never sent to our servers. You can read the details on our privacy policy page.
No app can protect you if you hand a code to a stranger, though. Your habits are the strongest defence.
What to do if you think you were scammed
- Call your bank or wallet provider immediately using the number printed on your card or inside the official app, not a number the caller gave you.
- Change your PIN and passwords from a safe device.
- Uninstall any remote-control or screen sharing app you installed at the caller's request.
- Report the number to your provider and, where available, to local cybercrime authorities.
- Warn family members, especially elderly parents, who are often targeted. Our guide on teaching parents smartphone basics can help.
FAQ
Is it ever safe to share my screen with support?
Only if you started the contact through an official channel and you are sure who you are talking to. Even then, never open banking apps or show OTPs while sharing.
Can a screen recording capture my OTP?
Yes, if the OTP appears as a notification or on screen while recording. Turning on Do Not Disturb before recording prevents this in most cases.
Why is my banking app black in recordings?
The app blocks capture on purpose to protect you. That is normal behaviour and not a fault in your recorder.
Does Cinematic Recorder send my recordings anywhere?
No. Recordings stay on your phone, and Google sign-in is optional.
Share your knowledge freely, but never your codes. A quick pause before every "share screen" request can save you from a very expensive mistake.
