Watch out! Viral 'prank video' will CRASH any iPhone or iPad almost instantly: Here's how to fix it
• The bug is reportedly hosted on a Russian social networking site
• A simple device reboot should fix the mysterious glitch
• Apple faced a similar bug on its iOS devices earlier this year

A malicious video circling the web will crash any model of iPhone or iPad.
Playing the video causes devices to slow down and eventually grind to a halt after just 30 seconds.

Apple is still unclear as to what causes the glitch, but the video is reportedly hosted on a Russian social networking site, Miaopai.

The bug is most likely sparked because the video is a corrupt file which starts a memory leak chain when it is opened in Apple's Safari web browser, reports The Next Web.

Apple's iOS operating system then fails to handle the problem as it multiplies, rapidly slowing the device down to a stop.

The iPhone-freezing video, discoveredis a short .mp4 clip of someone standing by a bed with the words 'Honey' written across the screen.

Apple expert Everything Apple Pro has made a YouTube video detailing the new glitch.

'It doesn't matter if you're using an iPhone or an iPod, this bug will crash the device,' he says.

'It doesn't have any long-lasting effects as far as I can tell,' he says.'It's completely crazy.

Android users have reported watching the video without any difficulties.

One macOS Sierra user even reports that the video crashed Safari on his MacBook Pro.

HOW TO FIX IT
Luckily, there is a quick fix for the problem.

A force reboot of the device should resolve the issue.
On older iPhones a force reboot is activated by pressing and holding the home and lock buttons together for around ten seconds.

On newer models like the iPhone 7, simply press and hold the lock and volume-down buttons together.

For the moment, there have been no reports of any long-term damage from the glitch.

Apple has faced similar bugs and glitches on their operating system before.

Earlier this year, a bug appeared on the internet that froze some Apple devices through Safari.

Users worldwide experienced the issue on both iPhones and iPads.
A suggested fix posted by users on Twitter advised turning off 'Safari Suggestions' in settings.

Apple rapidly resolved the issue within a few days.

And the California firm will likely be keen to squash this new bug just as quickly.

This may take a while though, as engineers attempt to hone in on precisely what is causing the strange bug and then develop a new patch as a blanket fix.

iPhone and iPad users should remain wary of unknown Safari pages and links until the new patch is rolled out.

Strangely, the glitch isn't specific to any one version of iOS, meaning the issue stretches back to both recent and older versions of the software.

The video will crash devices all the way back to iOS 5, released in 2011 and compatible with the iPhone 3Gs and original iPad.

Why cramming for exams never works: Brains 'panic' after last-minute revision and can't take in new information
• 'Retrieval practice', can protect the memory against the effects of stress
• Study of students showed they remembered more in stressful situations
• Students using this method have an advantage over those who simply re-read material in order to memorize it, claims the research

Every student who has panicked while reading the same page of a textbook over and over again may suspect this.
But stress cramming for an exam does not work, because the facts are likely to be lost from your memory.
Instead it is best to learn through practice tests to protect your brain from the effects of stress, with a study showing that we remember more this way.

n findings which will also help adults training at work, re-reading was found to work far less well under stress than active learning through practice.

Under pressure, researchers examining 120 students found those learning off a page remembered only an average of seven out of 30 words and images. But those who learned the words and images, then sat a timed practice test, were able to retrieve 11 of the 30 on average from their memory.

Senior study author Dr Ayanna Thomas, an associate psychology professor from Tufts University in Masachusetts, said: ‘Typically, people under stress are less effective at retrieving information from memory.

‘We now show for the first time that the right learning strategy, in this case retrieval practice or taking practice tests, results in such strong memory representations that even under high levels of stress, subjects are still able to access their memories.’

Co-author Amy Smith, a graduate psychology student at Tufts, added: ‘Our results suggest that it is not necessarily a matter of how much or how long someone studies, but how they study.’
‘Retrieval’ practice, or using practice tests, had already been found to work better when revising. But the new study, published in the journal Science, looked at how the two strategies worked under added pressure from stress.

The research team asked participants to learn a set of 30 words and 30 images which flashed up for a few seconds each on a computer screen. They took notes, typing sentences using the items they had seen, with some then taking practice tests and the rest studying conventionally.

The stress came after a 24-hour break when half of each group were forced to give an unexpected, impromptu speech and solve math problems in front of two judges, three peers and a video camera.

Their memory was tested during the stressful situation and then 20 minutes afterwards, to examine the brain under immediate and delayed stress responses.

Those who learned using the practice tests showed little damage to their memory from the stress, remembering an average of 11 out of 30 items compared to 10 for their non-stressed counterparts.
But those who learned by re-reading saw the items they remembered fall from just under nine items to seven on average.
It has previously been suggested that learning through practice tests allows the brain to encode knowledge, making it more likely to be stored.
Dr Thomas said: ‘Our one study is certainly not the final say on how retrieval practice influences memory under stress, but I can see this being applicable to any individual who has to retrieve complex information under high stakes.
‘Especially for educators, where big exams can put a great deal of pressure on students, I really encourage employing more frequent more low-stakes testing in context of their instruction.’

HOW THE STUDY WORKED
Some 120 students were asked to learn a set of 30 words and 30 images.

Each item was displayed for a few seconds on a computer screen.
To simulate note-taking, the students were given 10 seconds to type a sentence using the item immediately after seeing it.

The student group using retrieval practice took timed practice tests in which they recalled as many items as they could remember.
For the group using conventional study practice, items were re-displayed on the computer screen, one at a time, for a few seconds each.

They were given multiple time periods in which to study.
Following a 24-hour break, half of each group was placed into a stress-inducing scenario involving given an unexpected speech and solving two maths problems in front of two judges, three peers and a video camera.

Two memory tests were taken during the stress scenario and twenty minutes afterwards.

These involved recalling the words and images they had learned the day before.

The other half of the students took their two tests during and after a non-stressful task of the same length.

Is YOUR email address and password for sale? Hacker claims 200m Yahoo accounts are listed on a dark web market
• Credentials for 200m alleged Yahoo accounts being sold for 3 bitcoins
• This translates to about $1,860, and data reveals usernames and birth date
• Tests of a sample set show some usernames correspond to real accounts
• But, Yahoo has neither confirmed nor denied the hacker's claims

A cybercriminal known as ‘Peace’ has listed the credentials for 200 million alleged Yahoo accounts for sale on the dark web.

Samples of the data reveal usernames and dates of birth, along with other bits of personal information – and the massive set is being sold for just 3 bitcoins, roughly $1,860.

Yahoo has neither confirmed nor denied the claims, and many users may now want to change their passwords.

The hacker posted the listing on The Real Deal marketplace on Monday, Motherboard reveals, after first trading it privately.
This same cybercriminal has previously sold data from Myspace and LinkedIn.

According to Motherboard, who was able to obtain 5,000 records, many of the usernames tested correspond to real Yahoo accounts.
But, attempts to contact more than 100 of these resulted in messages returned as undeliverable, indicating that the account had either been disabled, or did not exist on the platform.
Yahoo has said it is aware of the claims, but the firm has not revealed whether this dataset is legitimate.

WHAT ARE THE CLAIMS?
The hacker claims the dataset listed on The Real Deal markerplace contains credentials for 200 million Yahoo accounts.
It's said to contain usernames, passwords, dates of birth, and some back-up email addresses.

Yahoo has not yet revealed if the data are legitmate.

We are aware of a claim,’ a Yahoo spokesperson told Motherboard in an email.

‘We are committed to protecting the security of our users’ information and we take any such claim very seriously.
'Our security team is working to determine the facts.

‘Yahoo works hard to keep our users safe, and we always encourage our users to create strong passwords, or give up passwords altogether by using Yahoo Account Key, and use different passwords for different platforms.’

Without confirmation or the release of the full dataset, it remains unclear when these records are from, and if this marks a new or legitimate data breach.

The hacker has told Motherboard that the dataset is from ‘2012 most likely.’

But, the information could have been taken from earlier leaks.
The recent scare comes just months after it was found that Russian hackers were trading hundreds of millions of stolen usernames and passwords belonging to Gmail, Hotmail, and Yahoo accounts.

Details of 40 million Yahoo Mail users, 33 million Hotmail users and 24 million Gmail accounts were in the data being traded.
The breach revealed in May is one of the biggest stashes of stolen credentials to be uncovered since cyber attacks hit major US banks and retailers two years ago.

The increasing threat of cybercriminals has prompted many companies, including Facebook and Netflix, to urge their customers to change their login details if they find matching credentials with other sites.

HOW TO CHOOSE A SECURE PASSWORD
Avoid favourite sports. ‘Baseball’ and ‘football’ were both in the top 10 worst password list.

Birthdays and years of birth are easy to guess with the help of personal information.

Common names such as Michael and Jennifer are insecure, with many making SplashData’s Top 50 list, too.

Experts suggest using eight mixed types of characters, with seemingly random combinations if possible.

They say that passphrases – short words with spaces or other characters separating them – are easy to recall and are relatively secure if seemingly random words are used.

Experts also advise having different passwords for different sites, instead of relying on one, which if hacked, could prove particularly serious.
