Hackers can steal PINs, passwords from your brainwaves: study

July 1, 2017

Washington, Jul 1: Hackers can guess a user's passwords by monitoring their thoughts, according to scientists including those of Indian origin who suggest that brainwave-sensing headsets need better security.brain

Electroencephalograph (EEG) headsets allow users to control robotic toys and video games with the mind.

Researchers at the University of Alabama at Birmingham in the US 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 programme.

"These emerging devices open immense opportunities for everyday users," said Nitesh Saxena, associate professor from University of Alabama. "However, they could also raise significant security and privacy threats as companies work to develop even more advanced brain-computer interface technology," said Saxena.

The team, including PhD student Ajaya Neupane, 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 programme 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 programme 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.

"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 analyse 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," he said.

Washington D.C., Jan 12: A recent study has claimed that people end up wasting almost an entire day when they take a vacation.

This can happen while standing in a queue or searching for places to visit, people do not keep a count of the time they have actually utilised during the trip. As a result, they end up doing much lesser activities than they originally had planned.

According to a recent report in Fox News, the study has also shared the fact that people try to justify time waste with planning and scheduling activities whereas the truth is that these things can be done well ahead to save time during the trip.

The average time waste according to the study commissioned by Sykes Holiday Cottages also said the people taking a seven days' trip waste a minimum of 17-and-a-half hours to figure out various factors.

But there are other causes involved as well. When one visits any crowded location, the real-time spent to enjoy the location is lesser than the time spent on reaching and trying to get involved. For instance, if one visits an amusement park, the activities take lesser time than the preparatory and other phases.

Facebook on Monday launched a new consumer marketing campaign in India titled 'More Together'. India is the first country in the Asia Pacific region where such a campaign is being rolled out.

It is also the first time that Facebook is rolling out a 'high decibel campaign of this stature in India', the company said in a statement.

It is also the first time that Facebook is rolling out a 'high decibel campaign of this stature in India', the company said in a statement.

"India is at the heart of Facebook and one of our focus areas this year is to tell the exciting story of a service that is deeply embedded in the fabric of India," said Ajit Mohan, Vice President and Managing Director, Facebook India.

The campaign would have multiple campaigns over the next few weeks in eight languages and the one will be set in the context of Holi.

Facebook in 2019 introduced a new company logo to further distinguish the company from the Facebook app.

The company recently announced the appointment of Avinash Pant as the Marketing Director for India operations, to drive the consumer marketing efforts across the family of apps.

Los Angeles, Apr 28: People who experience loss of smell as one of the COVID-19 symptoms are likely to have a mild to moderate clinical course of the disease, according to a study which may help health care providers determine which patients require hospitalisation.

The findings, published in the journal International Forum of Allergy & Rhinology, follows an earlier study that validated the loss of smell and taste as indicators of infection with the novel coronavirus, SARS-CoV-2.

According to the scientists from the University of California (UC) San Diego Health in the US, patients who reported loss of smell were 10 times less likely to be hospitalised for COVID-19 compared to those without the symptom.

"One of the immediate challenges for health care providers is to determine how to best treat persons infected by the novel coronavirus," said Carol Yan, first author of the current study and rhinologist from the UC San Diego Health.

"If they display no or mild symptoms, can they return home to self-quarantine or will they likely require hospitalisation? These are crucial questions for hospitals trying to efficiently and effectively allocate finite medical resources," Yan said.

The findings, according to the researchers, suggest that loss of smell may be predictive of a milder clinical course of COVID-19.

"What's notable in the new findings is that it appears that loss of smell may be a predictor that a SARS-CoV-2 infection will not be as severe, and less likely to require hospitalisation," Yan said.

"If an infected person loses that sense, it seems more likely they will experience milder symptoms, barring other underlying risk factors," she added.

Risk factors for COVID-19 previously reported by other studies include age, and underlying medical conditions, such as chronic lung disease, serious heart conditions, diabetes, and obesity.

In the current study, the scientists made a retrospective analysis between March 3 and April 8 including 169 patients who tested positive for COVID-19 at UC San Diego Health.

They assessed olfactory and gustatory data for 128 of the 169 patients, 26 of whom required hospitalisation.

According to the researchers, patients who were hospitalised for COVID-19 treatment were significantly less likely to report anosmia or loss of smell -- 26.9 per cent compared to 66.7 per cent for COVID-19-infected persons treated as outpatients.

Similar percentages were found for loss of taste, known as dysgeusia, they said.

"Patients who reported loss of smell were 10 times less likely to be admitted for COVID-19 compared to those without loss of smell," said study co-author Adam S. DeConde.

"Moreover, anosmia was not associated with any other measures typically related to the decision to admit, suggesting that it's truly an independent factor and may serve as a marker for milder manifestations of Covid-19," DeConde said.

The researchers suspect that the findings hint at some of the physiological characteristics of the infection.

"The site and dosage of the initial viral burden, along with the effectiveness of the host immune response, are all potentially important variables in determining the spread of the virus within a person and, ultimately, the clinical course of the infection," DeConde said.

If the SARS-CoV-2 virus initially concentrates in the nose and upper airway, where it impacts olfactory function, that may result in an infection that is less severe and sudden in onset, decreasing the risk of overwhelming the host immune response, respiratory failure, and hospitalisation, the scientists added.

"This is a hypothesis, but it's also similar to the concept underlying live vaccinations," DeConde explained.

"At low dosage and at a distant site of inoculation, the host can generate an immune response without severe infection," he added.

Loss of smell, according to the study, might also indicate a robust immune response which has been localised to the nasal passages, limiting effects elsewhere in the body.

Citing the limitations of the study, the scientists said they relied upon self-reporting of anosmia from participants, which posed a greater chance of recall bias among patients once they had been diagnosed with COVID-19.

They added that patients with more severe respiratory disease requiring hospitalisation may not be as likely to recognise or recall the loss of smell.

So the researchers said more expansive studies are needed for validating the results.
