Don’t believe everything you see. It turns out even your computer monitor can be hacked.
On Friday, researchers at DEF CON presented a way to manipulate the tiny pixels found on a computer display.
Ang Cui and Jatin Kataria of Red Balloon Security were curious how Dell monitors worked and ended up reverse-engineering one.
They picked apart a Dell U2410 monitor and found that the display controller inside can be used to change and log the pixels across the screen.
During their DEF CON presentation, they showed how the hacked monitor could seemingly alter the details on a web page. In one example, they changed a PayPal’s account balance from $0 to $1 million, when in reality the pixels on the monitor had simply been reconfigured.
