An innovative method of intercepting data from a MacBook keyboard using an infrared laser demonstrates potential security vulnerabilities in modern devices.
Laser Espionage
White Hat Hacker Experiment
Cybersecurity expert Samy Kamkar, known for his YouTube channel Applied Hacking , conducted an intriguing experiment. He attempted to improve upon existing technology by using an infrared laser to detect text entered by a MacBook user from a distance and without direct visual contact with the keyboard.
How the technology works
The method is based on the long-known principle of using a laser beam to detect and decipher sound waves. Previously, this technology was successfully used to intercept conversations behind glass, and has now found application in identifying typed text at a distance.
Implementation of the experiment
Kamkar directed a laser beam through the glass onto the back panel of the MacBook. He then recorded the vibrations in the case caused by key presses and tried to decode them.
History of the idea
The idea of creating such a spy installation came to Sami 15 years ago, after he saw a demonstration by two hackers , which showed simple detection of keystrokes using a laser pointed at a laptop from across the room.
Experiment Results
Although the results were not perfect, Kamkar was able to achieve some success. In the presented screenshots you can compare the original text typed by the user and the text recognized by the system:
MacBook Features
The MacBook turned out to be an ideal subject for experimentation thanks to the Apple logo with an almost mirror-like coating, providing a high-quality reflective surface.

Wow, this sounds like a plot from a spy movie! 🕵️♀️ Imagine how this can be used in real life. Although, to be honest, this technology scares me a little.
Hans
Yes, Isabella, this is really impressive! But I think this technology can be useful for security purposes. For example, to detect potential information leaks in companies. 🏢
Francois
I wonder how Apple will react to this. Perhaps they will improve the design of the MacBook to prevent such attacks. Although, to be honest, I would have preferred them to focus on improving the battery. 🔋
Elena
Guys, don't you think that this could lead to serious privacy problems? 😱 Imagine if someone could read your messages or passwords!
Giuseppe
I agree with Elena. This is truly alarming. But let's look at it from the other side - now we have a reason to work on strengthening the protection of our devices. Maybe it's time to switch to the good old pen and paper? 😄✍️

Some kind of nonsense. All these hackers do is come up with useless things. It would be better to do something useful, and not waste time on such nonsense. And in general, there is no point in spying on other people’s screens!
Sophia
Otto, don't be such a pessimist! This is a breakthrough in technology. Yes, it can be used for harm, but also for good. For example, to develop more advanced security systems. Progress cannot be stopped! 🚀
Dmytro
But here’s what I’m thinking: maybe this is a chance for IT companies to create a new market for security devices? Imagine special screens or cases that block laser scanning. Innovation begets innovation! 💡
