BITFINEX USERS TO SHARE 36% OF BITCOIN LOSSES AFTER HACK

BITFINEX USERS TO SHARE 36% OF BITCOIN LOSSES AFTER HACK
Bitfinex has told users they will share losses amounting to tens of millions of dollars equally

People who stored bitcoins at a popular exchange have been told they will lose 36% of their assets following a cyber-attack.

Hong Kong-based Bitfinex, where many users had stored the virtual currency to be used in transactions, said it lost up to $65m (£49m) in an attack.

The impact of the loss will now be shared across the site’s users.

One Bitcoin expert said the move to “socialise” losses had serious implications for digital currencies.

“Anyone who holds any asset at any exchange realises they’re part of the insurance plan for others,” said Emin Gun Sirer at Cornell University.

In a statement on its website, Bitfinex said, “We have decided to generalise losses across all accounts.

“Upon logging into the platform, customers will see that they have experienced a generalised loss percentage of 36.067%.”

More details of how this figure was reached would be published in the future, the firm added.

Customers were also told that they would receive a “BFX token” equal to their personal losses.
These tokens will eventually be exchanged either for repayment by Bitfinex or for shares in its parent company iFinex Inc.

In 2014, large Bitcoin exchange Mt Gox collapsed – leaving many out of pocket

Bitfinex has said that a total of 119,756 bitcoins were taken by hackers.

In May 2015, 1,500 bitcoins were stolen in a previous attack on the exchange.

It is not the first exchange to have suffered.

Many users lost large caches of Bitcoin after they disappeared from the Mt Gox exchange, which then declared bankruptcy in 2014.

‘Rough’ times ahead

Following the news that Bitfinex had suffered a substantial loss of bitcoins, the price of the cryptocurrency fell by more than 20% – though it has since rebounded slightly.

“It’s going to be rough,” Dr Sirer told the BBC.

“I think we’re going to see a move towards models with better understood insurance.”

The “vast majority” of people held bitcoins in exchanges and online wallets, according to security expert Prof Alan Woodward at the University of Surrey.

“It’s a bit like your bank account having money taken from it and then your bank writing to all customers saying it will spread the losses across all of them,” he told the BBC.

TESLA CAR 'DROVE OWNER TO HOSPITAL'

TESLA CAR 'DROVE OWNER TO HOSPITAL'
A US driver made it to hospital while suffering a pulmonary embolism after putting his car into autopilot.

Joshua Neally was driving his Tesla Model X home from his office in the US city of Springfield, Missouri, to nearby Branson.

But after pulling onto the highway, he started suffering piercing pain in his stomach and chest.

Rather than call an ambulance, the lawyer decided to find a hospital using his car’s self-driving mode.
Around 20 miles down the road, the 37-year-old’s Tesla arrived at the road leading to the hospital emergency department.

He told Slate that he manually steered the vehicle in to the car park and checked himself in to the emergency room.

A pulmonary embolism is a potentially fatal obstruction of a blood vessel in the lungs.

Doctors say he was lucky to survive it while driving.
Tesla’s autopilot, which automatically changes lanes and reacts to traffic, is under the microscope in America after it was involved in two crashes.

A man died in Florida after the driver-assist function in his Tesla Model S failed to detect a lorry in its path in May.
Then last month a driver was unhurt after his Model X car crashed after swerving to hit wooden rails next to a two-lane road in Montana.

The electric carmaker suggested that the function wasn’t being used correctly at the time of the second accident.

The use of the technology is being investigated by the US road safety watchdog, the National Highway Traffic Safety Administration.
But Joshua Neally says he was happy to use the autopilot function and thinks it will save lives.

“I’m very thankful I had it for this experience,” Joshua told local news station KY3.

“If something like that happens where I become unconscious or incapacitated while I’m driving, I’m not going to cross over the interstate and slam into somebody or slam into one of the big rock walls.”

THOUSANDS OF DELTA PASSENGERS DELAYED BY COMPUTER BUG

THOUSANDS OF DELTA PASSENGERS DELAYED BY COMPUTER BUG
passengers have been affected by a widespread computer issue at Delta Airlines

Travel disruption has hit thousands of passengers around the world, following a “system wide” computer bug at us airline Delta.
n Twitter, the Delta told passengers: “Our systems are down everywhere.”

Delays were reported at a string of airports, including in the US, the UK, Iceland and Japan.

The airline has said en route flights are unaffected, but passengers waiting to board should check their flight status while the issue is addressed.

“Delta experienced a computer outage that has impacted flights scheduled for this morning,” it said in a statement.

“Flights awaiting departure are currently delayed. Flights en route are operating normally.”

ANDROID BUG FEAR IN 900 MILLION PHONES

ANDROID BUG FEAR IN 900 MILLION PHONES
The flaws affect devices containing Qualcomm chips

Serious security flaws that could give attackers complete access to a phone’s data have been found in software used on tens of millions of Android devices.

The bugs were uncovered by Checkpoint researchers looking at software running on chipsets made by US firm Qualcomm.

Qualcomm processors are found in about 900 million Android phones, the company said.

However, there is no evidence of the vulnerabilities currently being used in attacks by cyberthieves.

“I’m pretty sure you will see these vulnerabilities being used in the next three to four months,” said Michael Shaulov, head of mobility product management at Checkpoint.

“It’s always a race as to who finds the bug first, whether it’s the good guys or the bad.”

Affected devices included:

BlackBerry Priv and Dtek50
Blackphone 1 and Blackphone 2
Google Nexus 5X, Nexus 6 and Nexus 6P
HTC One, HTC M9 and HTC 10
LG G4, LG G5, and LG V10
New Moto X by Motorola
OnePlus One, OnePlus 2 and OnePlus 3
Samsung Galaxy S7 and Samsung S7 Edge
Sony Xperia Z Ultra
Mr Shaulov said six months of work to reverse engineer Qualcomm’s code revealed the problems.
The flaws were found in software that handles graphics and in code that controls communication between different processes running inside a phone.

Exploiting the bugs would allow an attacker to gradually be able to take more control over a device and gain access to its data.

The flaws could be used to make booby-trapped apps that steadily gain access to a phone’s data

Checkpoint handed information about the bugs and proof of concept code to Qualcomm earlier this year.

In response, Qualcomm is believed to have created patches for the bugs and started to use the fixed versions in its factories.

It has also distributed the patches to phone makers and operators. However, it is not clear how many of those companies have issued updates to customers’ phones.

Checkpoint has created a free app called QuadRooter Scanner that can be used to check if a phone is vulnerable to any of the bugs, by looking to see if the patches for them have been downloaded and installed.

In addition, Mr Shaulov said Android owners should only download apps from the official Google Play store to avoid falling victim to malicious programs.

“People should call whoever sold them their phone, their operator or the manufacturer, and beg them for the patches,” said Mr Shaulov.

Qualcomm has yet to respond to a request for comment.

SCREEN TEST

SCREEN TEST
The show revolves around hacker Elliot Alderson (l) and his relationship with Mr Robot played by Christian Slater

From the latest Jason Bourne movie to CSI Cyber and countless other films and TV shows, hacks, hackers and hacking have never been more mainstream.

But few people who work in computer security can stand those programmes or movies because, in their words, they are so technically inept.

One TV show that has proved popular with hackers is NBC Universal’s Mr Robot which centres around Elliott Alderson – a security pro by day but who is also a member of an anti-establishment hacker group called FSociety that wants to use his technical skills to change the world.

Kor Adana, one of Mr Robot’s writers who worked in IT security before jumping to TV production, said the decision to make the show as technically accurate as possible was made even before the first episode was shot.

“I’ve got nothing but disdain for how Hollywood has portrayed hacking and technology before now,” he told a packed session at Def Con that was testament to the huge following Mr Robot has won among hackers.

“We wanted to do it right,” he said, “and we thought that doing it in a realistic way would be enticing and compelling.”

Mr Robot was voted best TV drama at the 2016 Golden Globes

Tool time
To help get the details correct, Mr Adana has recruited several technical consultants well-known in the Def Con and hacking community to advise on how the hacks Elliott uses can be accomplished.

The consultants develop the hacks, prove they work and then pass on information about how they were done to Mr Adana so they can be used on the show.

However, he said, drama demands that not every last detail of how Elliot cracks passwords, spoofs text messages, hacks phones or penetrates corporate and civil networks is shown.

“We have to strike a balance between what’s visually compelling and what we have to do to move the story forward,” he said.

Despite this the show does take care to make sure real and relevant hardware and software is used, he said. This attention to detail extends to the version numbers of software packages being used, command syntax, output format and screen layouts.

“We want to nail those details,” said Mr Adana. “It really helps to ground the show in reality if we can use real tools.”
Mr Adana extended an open invitation to the Def Con audience to contact him and the technical consultants with information about the tools they use so they can be featured on the show and used in its hacks.

Beyond the technology and hacks featured in the show, Mr Adana said it was also trying to make an important point about the contemporary role of technology.

“We live in an age where we are more dependent on devices than ever,” he said. “And there are a lot of the younger generation that know how to use apps but do not know about the ways in which they are vulnerable and how if they leave their phone unlocked it will not take long for it to be rooted.”

“If Mr Robot increases the level of awareness and paranoia out there then that’s a good thing,” he said.

Veteran hacker Marc Rogers, who develops and proves many of the hacks featured in the show, said he had been encouraged by the care it took to get the tech right.


The FSociety hacker group in Mr Robot shares some similarities with the Anonymous hacktivist group

“For years and years I have watched TV betray my community,” he said, “I want to see real stuff on TV that does not make me rage and which is an accurate portrayal of people in my community.”

“It’s been a gift to work on this,” he said.

Hard target
Andre McGregor, a consultant who formerly worked in the FBI’s cyber division, said he too was heartened by the care taken over the technology in the show.

“I find it refreshing that the accuracy is so important to them,” he said, adding that he was approached to help with Series Two of Mr Robot because several episodes feature law enforcement and government responses to cyber attacks.

Mr McGregor said his advice extended beyond helping the show’s writers understand how the FBI and law enforcement agencies investigate cyber intrusions and conduct interviews. It also involved more subtle elements such as how FBI agents arrange themselves in a room during a meeting or interrogation, he said.

“An agent would never stand in front of a door,” he said. “It’s what we call the ‘fatal funnel’, you could be hit by a shotgun blast through that door.”

But there were some things that the show did gloss over, said consultant Ryan Kazanciyan, a former penetration tester who is now head of forensics at security firm Tanium.

“It’s missing the time, the number of steps you have to go through for a hack, complexity and the amount of research you have to do,” he said.

“When I would do penetration testing I would have one or two weeks to get in from the outside and then one or two weeks to see how much damage I could do from the inside,” he said.

“Sometimes I would go for days just coming up blank,” he said. “And then you would have that Aha! moment that gets you in.”

He said one facet of hacking the show did get right was the view of the world that anyone with an understanding of security software swiftly acquires.

“There’s always a way in,” he said.

FACEBOOK TESTS EXPRESS WI-FI SERVICE IN INDIA

FACEBOOK TESTS EXPRESS WI-FI SERVICE IN INDIA
As well as India, Facebook wants to bring internet connectivity to hard-to-reach parts of Africa

Facebook has confirmed that it is in the early stages of testing a wi-fi service with Indian internet service providers (ISPs).

Express Wi-fi allows users to purchase data from local providers in order to access the web.

A pilot version with a state-run telecoms company has already been offered at 125 rural wi-fi hotspots.

In a statement, Facebook said the tests were being carried out with “multiple local ISP partners”.

Facebook is probably hoping that users who first encounter the web via a Facebook initiative will be more likely to become users of the social network – rather than a competitor – according to Ian Fogg, an analyst at IHS Technology.

“In emerging economies, Facebook is pursuing an intervention strategy to increase the pace of internet and online usage because this will also raise the addressable market for Facebook,” he told the BBC.

Earlier this year, Facebook’s Free Basics internet service app was blocked by India’s telecoms regulator.

A ruling in favour of net neutrality put a stop to the plans, which would have offered free access to a select number of websites only.

Health Tips That Will Help You Deal With Grief

All humans have had to grieve at one point in our lives. Losing a job, a property, an opportunity, a pet, and above all a loved one can cause us to grieve. At that point, we feel pain, sadness and sometimes anger.

You see, grieving is a natural thing, we all have had to pass through difficult circumstances. Before I delve into the health tips that'll help you cope with grief, I will like for you to understand what grief is and some other important points.
Grief

Grief is the natural emotional pain that arises from misfortune or personal loss, when something or someone you love is taken away. Naturally, the more important the loss is, the more intense the grief will be.
Now here are some important points to note.

• Don't ignore the pain, to effectively deal with grief you must face it, and overcome it.

• Everybody grieves differently, there are mental differences. For example, someone that doesn't cry in the face of loss can't be said  to be feeling less sad.

• Recovering from grief takes time, but doesn't have a time frame.

Please keep these points in mind as we then consider these beneficial health tips.
