Study finds hackers could use brainwaves to steal passwords

Researchers at the University of Alabama at Birmingham suggest that brainwave-sensing headsets, also known as EEG or electroencephalograph headsets, need better security after a study reveals hackers could guess a user’s passwords by monitoring their brainwaves.

EEG headsets are advertised as allowing users to use only their brains to control robotic toys and video games specifically developed to be played with an EEG headset. There are only a handful on the market, and they range in price from $150 to $800.

Nitesh Saxena, Ph.D., associate professor in the UAB College of Arts and Sciences Department of Computer and Information Sciences, and Ph.D. student Ajaya Neupane and former master’s student Md Lutfor Rahman, found that a person who paused a video game and logged into a bank account while wearing an EEG headset was at risk for having their passwords or other sensitive data stolen by a malicious software program.

“These emerging devices open immense opportunities for everyday users,” Saxena said. “However, they could also raise significant security and privacy threats as companies work to develop even more advanced brain-computer interface technology.”

Saxena and his team used one EEG headset currently available to consumers online and one clinical-grade headset used for scientific research to demonstrate how easily a malicious software program could passively eavesdrop on a user’s brainwaves. While typing, a user’s inputs correspond with their visual processing, as well as hand, eye and head muscle movements. All these movements are captured by EEG headsets. The team asked 12 people to type a series of randomly generated PINs and passwords into a text box as if they were logging into an online account while wearing an EEG headset, in order for the software to train itself on the user’s typing and the corresponding brainwave.

“In a real-world attack, a hacker could facilitate the training step required for the malicious program to be most accurate, by requesting that the user enter a predefined set of numbers in order to restart the game after pausing it to take a break, similar to the way CAPTCHA is used to verify users when logging onto websites,” Saxena said.

The team found that, after a user entered 200 characters, algorithms within the malicious software program could make educated guesses about new characters the user entered by monitoring the EEG data recorded. The algorithm was able to shorten the odds of a hacker’s guessing a four-digit numerical PIN from one in 10,000 to one in 20 and increased the chance of guessing a six-letter password from about 500,000 to roughly one in 500.

EEG has been used in the medical field for more than half a century as a noninvasive method for recording electrical activity in the brain. Electrodes are placed on the surface of the scalp to detect brain waves. An EEG machine then amplifies the signals and records them in a wave pattern on graph paper or a computer. EEG can be combined with a brain-computer interface to allow a person to control external devices. This technology was once highly expensive and used mostly for scientific research, like the production of neuroprosthetic applications to help disabled patients control prosthetic limbs by thinking about the movements. However, it is now being marketed to consumers in the form of a wireless headset and is becoming popular in the gaming and entertainment industries.

“Given the growing popularity of EEG headsets and the variety of ways in which they could be used, it is inevitable that they will become part of our daily lives, including while using other devices,” Saxena said. “It is important to analyze the potential security and privacy risks associated with this emerging technology to raise users’ awareness of the risks and develop viable solutions to malicious attacks.”

One potential solution proposed by Saxena and his team is the insertion of noise anytime a user types a password or PIN while wearing an EEG headset.

““One of the holy grails of biomaterials research has been working out a way to get skin to grow onto and attach to metals and plastics without the risk of infection. It looks like this design and technique may have solved the problem,” says Dr Stynes, who is researching his PhD at the University of Melbourne. “It could pave the way for fully implantable robotics, prosthetics, catheters, intravenous lines, and the reconstruction of surgical defects with artificial materials.” Professor Richard Page, Director of Orthopaedics and the Centre of Orthopaedic Research and Education at Barwon Health and Deakin University, said the ability of the scaffold to make the skin think it was growing on other skin is potentially a major finding.”

Bio-Inspired Material Interacts with Surrounding Tissue to Promote Healing.

A research team from Imperial College London, led by Dr Ben Almquist, has developed a new molecule based on so-called traction force-activated payloads (TrAPs) which allow materials to talk to the body‘s natural repair systems and thereby activate healing processes. “Creatures from sea sponges to…

Breakthrough in blending metals—precise control of multimetallic one-nanometer cluster formation achieved

Researchers in Japan have found a way to create innovative materials by blending metals with precision control. Their approach, based on a concept called atom hybridization, opens up an unexplored area of chemistry that could lead to the development of advanced functional materials.

Multimetallic clusters—typically composed of three or more metals—are garnering attention as they exhibit properties that cannot be attained by single-metal materials. If a variety of metal elements are freely blended, it is expected that as-yet-unknown substances are discovered and highly-functional materials are developed. So far, no one had reported the multimetallic clusters blended with more than four metal elements so far because of unfavorable separation of different metals. One idea to overcome this difficulty is miniaturization of cluster sizes to one-nanometer scale, which forces the different metals to be blended in a small space. However, there was no way to realize this idea.

Mars Surface Is Looking Much Deadlier Than We Previously Thought

So much for those space potatoes.

A new study has revealed that compounds present in the Martian soil can wipe out whole bacterial cultures within minutes.

Researchers have had their suspicions over whether microorganisms can actually survive on the surface of the Red Planet, and now lab tests are spelling doom for any potential little green bacteria. And yeah, growing potatoes on Mars might be more difficult than we thought.

The problem here lies with perchlorates - chlorine-containing chemical compounds that we first detected on Mars back in 2008. These salty compounds are also what makes water on the Martian surface stay liquid, essentially turning it into brine.

Perchlorates are considered toxic for people, but they don’t necessarily pose a problem for microbes. And because they keep surface water liquid, on Mars the presence of these compounds could even be beneficial for life - or so we thought.

Researchers from the University of Edinburgh have now confirmed that when you pair the compounds with intense ultraviolet (UV) light exposure, things become grim for any life forms.
