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.

Will Google’s Algorithm Stop Piracy?
Comments Off on Will Google’s Algorithm Stop Piracy?
Nosey Google has updated its search engine algorithms in an attempt to restrict piracy web sites appearing high in its search rankings.
The update will mean piracy sites are less likely to appear when people search for music, films and other copyrighted content.
The decision to roll out the search changes was announced in a refreshed version of a How Google Fights Piracy report, which was originally published in September 2013.
However, this year’s updated report features a couple of developments, including changes to ad formats and an improved DMCA demotion search signal.
The move is likely to be a result of criticism received from the entertainment industry, which has argued that illegal sites should be “demoted” in search results because they enable people to find sites to download media illegally.
The biggest change in the Google search update will be new ad formats in search results on queries related to music and movies that help people find legitimate sources of media.
For example, for the relatively small number of queries for movies that include terms like ‘download’, ‘free’, or ‘watch’, Google has instead begun listing legal services such as Spotify and Netflix in a box at the top of the search results.
“We’re also testing other ways of pointing people to legitimate sources of music and movies, including in the right-hand panel on the results page,” Google added.
“These results show in the US only, but we plan to continue investing in this area and to expand it internationally.”
An improved DMCA demotion signal in Google search is also being rolled out as part of the refresh, which down-ranks sites for which Google has received a large number of valid DMCA notices.
“We’ve now refined the signal in ways we expect to visibly affect the rankings of some of the most notorious sites. This update will roll out globally starting next week,” Google said, adding that it will also be removing more terms from autocomplete, based on DMCA removal notices.
The new measures might be welcomed by the entertainment industry, but are likely to encourage more people to use legal alternatives such as Spotify and Netflix, rather than buying more physical media.
