PC Monitors Vulnerable To Hacking
You should probably be leery of what you see since, apparently, your computer monitor can be hacked.
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.
It wasn’t exactly an easy hack to pull off. To discover the vulnerability, both Cui and Kataria spent their spare time over two years, conducting research and understanding the technology inside the Dell monitor.
However, they also looked at monitors from other brands, including Samsung, Acer and Hewlett Packard, and noticed that it was theoretically possible to hack them in the same manner as well.
The key problem lies in the monitors’ firmware, or the software embedded inside. “There’s no security in the way they update their firmware, and it’s very open,” said Cui, who is also CEO of Red Balloon.
The exploit requires gaining access to the monitor itself, through the HDMI or USB port. Once done, the hack could potentially open the door for other malicious attacks, including ransomware.
For instance, cyber criminals could emblazon a permanent message on the display, and ask for payment to remove it, Kataria said. Or they could even spy on users’ monitors, by logging the pixels generated.
However, the two researchers said they made their presentation to raise awareness about computer monitor security. They’ve posted the code to their research online.
“Is monitor security important? I think it is,” Cui said.
Dell couldn’t be reached for immediate comment.

Intel Developing Thunderbolt Technology
Comments Off on Intel Developing Thunderbolt Technology
A new interconnect technology being developed by Intel could be ready for market by 2015 and will be able to move data between computers at up to five times the speed of its recently launched Thunderbolt technology, an Intel researcher said earlier this week.
The new technology uses silicon photonics, which combines silicon components with optical networking, to transfer data at up to 50 gigabits per second over distances of up to 100 meters, said Jeff Demain, strategy director of circuits and system research at Intel Labs, at a company event in New York.
Intel expects the technology to be ready for use in PCs, tablets, smartphones, televisions and other products by 2015, Demain said. As well as being faster than today’s interconnect technologies, it’s expected to lower costs because the components will be built using existing silicon manufacturing processes.
The technology could possibly be used in TVs and set-top boxes to carry video streams at much higher definition than those available today. Image resolution is likely to quadruple by the middle of the decade, when successors to 1080p have arrived, and that will mean more data has to be pushed to the TV.
It should also enable faster data transfers between smartphones, tablets, PCs and peripherals such as external storage drives.
The technology still has a way to go, but Intel showed its progress at the event in New York Wednesday. It showed what it said were working prototypes of the silicon chips used to transmit and receive the laser signals.
