Here’s Why You Should Be Cautious While Setting Pins on Your Smartphone Device or You Can Get Hacked Anytime

In the experiment, the IT security experts used various blacklists, including the real one from Apple, which they obtained by having a computer test all possible PIN combinations on an iPhone

 If your iPhone or Android smartphone PIN starts with 1234, 0000, 2580, 123456 or 654321, you are in a soup as these PINs are most prone to hacking as your device can be unlocked easily by others.

According to the study, the 10 most popular four-digit PINs are: 1234, 0000, 2580, 1111, 5555, 5683, 0852, 2222, 1212, 1998. The most popular six-digit PINs are and 123456, 654321, 111111, 000000, 123123, 666666, 121212, 112233, 789456,159753. Researchers at Ruhr University in Germany showed that the blacklist used by Apple to prevent particularly frequent PINs could be optimised and that it would make even greater sense to implement one on Android devices.

It emerged that six-digit PINs do not provide more security than four-digit ones. “Mathematically speaking, there is a huge difference, of course. A four-digit PIN can be used to create 10,000 different combinations, while a six-digit PIN can be used to create one million,” said study researcher Philipp Markert from Horst Gortz Institute for IT Security in Ruhr University.

“However, users prefer certain combinations; some PINs are used more frequently, for example, 123456 and 654321, this means users do not take advantage of the full potential of the six-digit code,” Markert added. According to the researchers, it seems that users currently do not understand intuitively what it is that makes a six-digit PIN secure.

For the findings, the research team investigated how users choose the PIN for their mobile phones and how they can be convinced to use a more secure number combination. The team asked Apple and Android users set either four or six-digit PINs and later analysed how easy they were to guess.

In the process, they assumed that the attacker did not know the victim and did not care whose mobile phone is unlocked. Accordingly, the best attack strategy would be to try the most likely PINs first. Some of the participants were free to choose their PIN at random. Others could only choose PINs that were not included in a blacklist. If they tried to use one of the blacklisted PINs, they received a warning that this combination of digits was easy to guess.

In the experiment, the IT security experts used various blacklists, including the real one from Apple, which they obtained by having a computer test all possible PIN combinations on an iPhone. Moreover, they also created their own more or less comprehensive blacklists. A prudently chosen four-digit PIN is secure enough, mainly because manufacturers limit the number of attempts to enter a PIN. Apple locks the device completely after ten incorrect entries, the researcher said.

On an Android smartphone, different codes cannot be entered one after the other in quick succession. “In eleven hours, 100 number combinations can be tested,” Markert said. The researchers also found 274 number combinations on Apple’s blacklist for four-digit PINs.

“Since users only have 10 attempts to guess the PIN on the iPhone anyway, the blacklist does not make it any more secure,” said study researcher Maximilian Golla. According to the researchers, the blacklist would make more sense on Android devices, as attackers can try out more PINs there.

The research has shown that the ideal blacklist for four-digit PINs would have to contain about 1,000 entries and differ slightly from the list currently used by Apple. (IANS)

The phenomenon known as "gaze cueing," a powerful signal for orienting attention, is a mechanism that likely plays a role in the developmentally and socially important wonder of "shared" or "joint" attention where a number of people attend to the same object or location. Pixabay

 As more and more people use video conferencing tools to stay connected in social distancing times, neuroscientists from Florida Atlantic University have found that a person’s gaze is altered during tele-communication if they think that the person on the other end of the conversation can see them.

The phenomenon known as “gaze cueing,” a powerful signal for orienting attention, is a mechanism that likely plays a role in the developmentally and socially important wonder of “shared” or “joint” attention where a number of people attend to the same object or location.

“Because gaze direction conveys so much socially relevant information, one’s own gaze behaviour is likely to be affected by whether one’s eyes are visible to a speaker,” said Elan Barenholtz, associate professor of psychology. For example, people may intend to signal that they are paying more attention to a speaker by fixating their face or eyes during a conversation.

“Conversely, extended eye contact also can be perceived as aggressive and therefore noticing one’s eyes could lead to reduced direct fixation of another’s face or eyes. Indeed, people engage in avoidant eye movements by periodically breaking and reforming eye contact during conversations,” explained Barenholtz.

People are very sensitive to the gaze direction of others and even two-day-old infants prefer faces where the eyes are looking directly back at them. Social distancing across the globe due to coronavirus (COVID-19) has created the need to conduct business “virtually” using Skype, web conferencing, FaceTime and any other means available.

For the study, published in the journal Attention, Perception & Psychophysics, the team compared fixation behaviour in 173 participants under two conditions: one in which the participants believed they were engaging in a real-time interaction and one in which they knew they were watching a pre-recorded

The researchers wanted to know if face fixation would increase in the real-time condition based on the social expectation of facing one’s speaker in order to get attention or if it would lead to greater face avoidance, based on social norms as well as the cognitive demands of encoding the conversation.

Results showed that participants fixated on the whole face in the real-time condition and significantly less in the pre-recorded condition. In the pre-recorded condition, time spent fixating on the mouth was significantly greater compared to the real-time condition. There were no significant differences in time spent fixating on the eyes between the real-time and the pre-recorded conditions. To simulate a live interaction, the researchers convinced participants that they were engaging in a real-time, two-way video interaction (it was actually pre-recorded).

When the face was fixated, attention was directed toward the mouth for the greater percentage of time in the pre-recorded condition versus the real-time condition. “Given that encoding and memory have been found to be optimized by fixating the mouth, which was reduced overall in the real-time condition, this suggests that people do not fully optimize for speech encoding in a live interaction,” the authors wrote.
