Hackers are only able to edit your online passwords from the sound of your keystrokes, a new study has revealed.
The latest cyber threat is hackers using cell phones to track their keystrokes victim. In tests, the researchers were able to identify what was typed with remarkable precision using only one smartphone.
It could pose a serious threat to people who use laptops on public places such as cafes, libraries and public transport.
Cybersecurity experts at Southern Methodist University in Texas have found that the sound waves produced when typing on a keyboard can be successfully downloaded from a smartphone.
The acoustic signals which can be blocked by the phone can then be edited, allowing a specialized hacker to decipher which keys were used and what they were typing.
Researchers have been able to decode many of what they typed using standard keyboards and smartphone - even in a noisy boardroom where others were typing and talking.
Co-author of the study, Eric Larson, said: "We were able to pinpoint what people are typing with an 41% word accuracy rate. And we can extend it - above 41% - by looking at, for example, the 10 top words from what we think they could be. »
Research has revealed that it only takes seconds to get information about what someone is typing.
Professor Larson said: "Based on what we have found, I believe that smartphone makers should go back to the design point and make sure they enhance the privacy with which people have access to these sensors in a smartphone«.
In an attempt to create a realistic scenario, the researchers arranged to meet with many people in a conference room, talking to each other and taking notes on a laptop.
Study participants were not given instructions on what to say when they spoke and were allowed to use either small or full sentences when typing. They were also able to correct or correct typographical errors, and basically act as they saw fit.
Professor Larson said: "We have looked at the security holes that may exist when you have your smartphone with you.
"We wanted to know if what you type on your laptop or any keyboard for that matter could only be felt by the cell phones that are on the same table.
Cell phones contain sensors to detect orientation whether they are in a bank or if they are carried in one's pocket. Some sensors require the user to give permission to activate them, but many are always active.
Professor Larson said: "A successful one monitoring that kind of thing could be very scary because there is no way to know if you have been cheated that way. "
The study was published in the journal Interactive, Mobile, Wearable and Ubiquitous Technologies.
