Is your kid obsessed with video games and hanging out with questionable friends? Researchers have identified characteristics and gender-specific behaviours in kids that could lead them to become juvenile hackers.

The study found that kids who had mobile phone access early on were more likely to hack — especially if they lived in larger cities. The researchers also explained the stark differences between boys and girls when it came to hacking.

“We found that predictors of juvenile delinquency, like low self-control are big factors for computer hacking for both boys and girls,” said study lead author Thomas Holt from Michigan State University in the US.

“But for girls, peer associations mattered more. If she has friends who shoplift or engage in petty forms of crime, she’s more likely to be influenced to hack as well. For boys, we found that time spent watching TV or playing computer games were associated with hacking,” Holt added.

For the study published in the journal Crime & Delinquency, the research team assessed responses from 50,000 teens from around the world to determine predictors of hacking.

The study found that spending time with peers was more likely to influence delinquent behaviour for those living in smaller cities.

Besides, having their own bedroom, their own computer or the freedom of doing what they want on the Internet without parental supervision.

The researchers also revealed a connection between pirating movies and music and hacking.

“The initial attempts might not be serious, but without supervision and low self-control, it’s likely they got a taste for what they might be able to accomplish by taking their hacking abilities further,” Holt said. (IANS)

Ultrasonic waves do not make a sound, but they can still activate Siri on your cellphone and have it make calls, take images or read the contents of a text to a stranger – without the phone owner’s knowledge, suggests a new research.

Researchers have previously shown that ultrasonic waves can be used to deliver a single command through the air. However, the new research from Washington University in St. Louis expands the scope of vulnerability that ultrasonic waves pose to cellphone security.

These waves, the researchers found, can propagate through many solid surfaces to activate voice recognition systems and — with the addition of some cheap hardware — the person initiating the attack can also hear the phone’s response.

The results were presented at the Network and Distributed System Security Symposium in San Diego. “We want to raise awareness of such a threat,” said Ning Zhang, Assistant Professor of at the McKelvey School of Engineering. “I want everybody in the public to know this.”

Zhang and his co-authors were able to send “voice” commands to cellphones as they sat inconspicuously on a table, next to the owner. With the addition of a stealthily placed microphone, the researchers were able to communicate back and forth with the phone, ultimately controlling it from afar. Ultrasonic waves are sound waves in a frequency that is higher than humans can hear. Cellphone microphones, however, can and do record these higher frequencies.

“If you know how to play with the signals, you can get the phone such that when it interprets the incoming sound waves, it will think that you are saying a command,” Zhang said. To test the ability of ultrasonic waves to transmit these “commands” through solid surfaces, the research team set up a host of experiments that included a phone on a table.

Attached to the bottom of the table was a microphone and a piezoelectric transducer (PZT), which is used to convert electricity into ultrasonic waves. On the other side of the table from the phone, ostensibly hidden from the phone’s user, is a wave form generator to generate the correct signals. The team ran two tests, one to retrieve an SMS (text) passcode and another to make a fraudulent call.

The first test relied on the common virtual assistant command “read my messages” and on the use of two-factor authentication, in which a passcode is sent to a user’s phone — from a bank, for instance — to verify the user’s identity. The attacker first told the virtual assistant to turn the volume down to Level 3. At this volume, the victim did not notice their phone’s responses in an office setting with a moderate noise level.

Then, when a simulated message from a bank arrived, the attack device sent the “read my messages” command to the phone. The response was audible to the microphone under the table, but not to the victim.

In the second test, the attack device sent the message “call Sam with speakerphone,” initiating a call. Using the microphone under the table, the attacker was able to carry on a conversation with “Sam.” The team tested 17 different phone models, including popular iPhones, Galaxy and Moto models. All but two were vulnerable to ultrasonic wave attacks.

Ultrasonic waves made it through metal, glass and wood. Zhang said there is a simple way to keep a phone out of harm’s way of ultrasonic waves: the interlayer-based defence, which uses a soft, woven fabric to increase the “impedance mismatch.” In other words, put the phone on a tablecloth. (IANS)
