One in seven people on the planet now use Facebook to stay in touch, according to the social networking giant’s founder and CEO Mark Zuckerberg.

The eight-year-old company added 200 million new users in the last year, bringing its total number of “friends” to a billion across the world.

Mr Zuckerberg announced the milestone in an interview with NBC on Thursday, describing the development as “an amazing honour”.

“To be able to come into work every day and build things that help a billion people stay connected with the people they care about every month, that’s just unbelievable,” the 28-year-old tech guru said.

But he also admitted Facebook had been in a “tough cycle” since the company’s initial public offering in May. Shares in the social networking site on the Nasdaq stock exchange have lost around 50% since.

When the company went public, 421 million shares were issued at $38 (£24.20) each, rising as high as $45 (£28.66) each after trading began. But the stock closed on its first day barely above its initial public offering price of $38 and has been below that level since.

Shares were trading slightly up just after the open on Thursday, at $21.99 (£13.65).

“Things go in cycles. We’re obviously in a tough cycle now and that doesn’t help morale. But at the same time, you know, people here are focused on the things that they’re building,” said Mr Zuckerberg of his staff.

“I mean, you get to build things here that touch a billion people, which is just not something that you can say at almost anywhere else, so I think that’s really the thing that motivates people.”

Mr Zuckerberg, who founded Facebook in 2004 while at Harvard University, controls more than half of the voting stock. But the drop in the company’s value has raised questions about his abilities as a chief executive.

“I take this responsibility that I have really seriously and I really think Facebook needs to be focused on building the best experiences for people around the world, right? And we have this philosophy that building the products and services and building the business go hand in hand,” he told NBC.

Mr Zuckerberg said Facebook would be targeting new and current users on mobile devices, such as smartphones, to grow the site’s customer base and enhance its ability to make money.

  • Iran claims cyber war is deadlier than physical attacks - is it paranoia, or reality? (Image: Rex)

     

A spokesperson for the Iranian military said this week that the country viewed cyber war as MORE dangerous than physical attacks.

Iran has already been victim of a cyber attack designed to damage equipment at its Busehr nuclear plant. The attack is thought to have been ordered by the U.S.

“We have armed ourselves with new tools, because a cyber war is more dangerous than a physical war,” said Abdollah Araqi, deputy commander of ground forces in the Islamic Revolutionary Guard Corps (IRGC).

But is this paranoia – or a justifiable fear of a new kind of invisible war?

 

President Obama was the victim of cyber crime in 2008, with hackers rifling through his campaign website and stealing emails in an attack the President described as a ‘powerful reminder’ of the scope of cyber crime.

But the President is also widely suspected of having personally issued orders regarding the Stuxnet worm, a sophisticated attack which targeted Iran’s Busehr nuclear plant, with the aim of destroying equipment by spinning it out of control.

David Sanger’s book Confront and Conceal alleges that the President was not only fully aware of the attack, he ordered it to continue after the worm spread beyond the initial computers it was built to target.


America is widely thought to be the ‘world leader’ in cyber weaponry – with a history of hi-tech attacks that stretches back to a CIA attack on a Russian oil pipeline, thought to be have been blown up with corrupted software in 1982. One of the predecessors of the internet, ARPANET, was funded by a wing of the U.S military.

The same wing’s successor, DARPA  – the Defence Advanced Research Projects Agency – is currently soliciting bids for a new Plan X capability to help with ‘managing cyberwarfare’.

Defence companies are open – at least off the record – about the fact there are ‘black’ versions of the defensive software and hardware they sell to governments and private enterprise.

These are the test-beds built to refine cyber weapons. More than 100 nations are thought to be developing some kind of cyber weapon capability.

‘It’s a very complex problem,’ says Kevin Haley, Norton’s Director of Security Response, ‘There need to be treaties about cyberspace, and more rules around this. There needs to be more regulations – and more enforcement of existing laws.’

At present, cyberspace is something of a Wild West – with states able to disown cyber attacks as the work of rogue individuals.

As a result, it’s often difficult to tell whether ‘cyber war’ is an illusion dreamed up by defence companies – or whether it’s already happening.

Chinese hackers penetrated Nasa systems including ones used to manoeuvre the International Space Station. The Chinese government has always denied any association with such cyber attacks, but it is suspected of having been behind cyber attacks stretching as far back as 2003 and the sustained ‘Titan Rain’ attacks against US companies.

In 2011, U.S. government accounts were penetrated by hackers in China, after their Google Mail accounts were hacked. The targeting of government officials led many to suspect the Chinese government was involved – and the attacks originated in Jinan, home of the Chinese army’s ‘Technical Reconnaissance Bureaus.’

‘Blaming these misdeeds on China is unacceptable,’ said Chinese foreign ministry spokesman Hong Lei after the attacks.

‘Hacking is an international problem and China is also a victim. The claims of so-called support for hacking are completely unfounded.’
Google’s Mail service now has a specific warning that states, ‘We believe state-sponsored attackers are attempting to compromise your account.’

‘When we have specific intelligence—either directly from users or from our own monitoring efforts—we show clear warning signs,’ Google said in a blog post. ‘Today, we’re taking that a step further for a subset of our users, who we believe may be the target of state-sponsored attacks.’

A series of linked attacks by Russian cyber attackers blacked out banks, newspapers, comment websites and government websites in Estonia in 2007, after a dispute between the two countries over the relocation of a Soviet-era grave marker.

It was widely speculated that the Kremlin had ordered the attacks.

With other attacks, the sheer sophistication of the software hints that nations must have been involved. Run-of the-mill hackers don’t spend $1 million up front on software – the amount the Stuxnet worm is thought to have cost to develop. It is thought to have taken at least six months to create.

Stuxnet is thought to have been part of a family of related malicious software packages – including Duqu, used to steal data from computers in the Middle East, all created by governments, perhaps the United States in collaboration with other powers. In cyber war, governments will have a serious advantage over smaller groups.

But the sheer unpredictability of ‘rogue’ hackers may give them an advantage the lumbering machinery of government can’t deal with.

‘The challenge with hacktivist groups,’ says Norton’s Director of Security Response, Kevin Haley, ‘Is that they are a non-state actor. So far, they haven’t achieved great things – they have stolen people’s logins and passwords and launched denial of service attacks. But we don’t know where they will attack – or what.’

    Yahoo! News – Polish security researchers have revealed a security flaw they claim may affect up to a billion PC users (Picture: Fotolia)

Polish security researchers have uncovered a security vulnerability which they claim leaves up to a billion PC and Mac users at risk.

The vulnerability is in the Java software used with web browsers such as Firefox, Chrome, Safari and Internet Explorer.

The bug allows cyber criminals to hijack PCs running Java, and potentially install malicious software at will. It is currently ‘unpatched’ which means that anyone using Java – used commonly on the web – is potentially at risk.

At present, there is no downloadable ‘fix’. Users can stop their browser using Java, or uninstall it, but this may cause some websites and services to stop working.

[Related: Scientists design clock that will keep time after the universe ends ]

The vulnerability affects all versions of Java software.

The researchers, from Security Explorations, managed to bypass ‘sandbox’ protections to take control of PC systems.

Their findings have been forwarded to Oracle, makers of Java.

“The impact of this issue is critical – we were able to successfully exploit it and achieve a complete Java security sandbox bypass,” says Adam Gowdiak, who posted the news to the Full Disclosure security mailing list. “One billion users of Oracle Java SE software are vulnerable to yet another security flaw.”

So far, no cyber criminals have taken advantage of the flaw. Earlier this year, criminal gangs took advantage of previous ‘exploits’ in Java to mount cyber attacks.

Norton’s senior manager for security response, Orla Cox, said that a far Eastern gang of criminals called ‘Nitro’ used a previous Java exploit to mount attacks.

Parents’ Facebook sting helps catch Skagit sex offender

“When I met him, he was totally charming, really likable,” said Julie.

He is 19-year-old William Elms, also known as Liam. Liam was dating the Myrfors’ 17-year-old-daughter.

Then, Julie and Jesper learned Liam was a registered sex offender.

“When there’s a question, follow it. Find the answer for your kids,” said Julie.

With some help, the parents set up a sting.

“Why not make a Facebook and create a girl?” said Julie.

“When we did this, we had rules. We were not trying to entrap him. We were setting him up a situation where, if he was a bad guy, he could act on it,” said Jesper.

And he did. He began sending explicit messages and pictures.

“My daughter didn’t know we had done this. I invited her on to begin watching live. She started watching conversations on our fake little person,” said Julie.”The hardest part as a parent was watching her heart break.”

so what are your thoughts on it is it safe is it not? seing this to me i find it a very unstable social networking site.
