Cutting off the Internet won’t keep you safe from long-distance hackers, Ben Gurion University researchers discovered. Using a technique called air-gap network hacking, all a hacker has to do is implant the right kind of malware into a cellphone that gets within range of a computer. Hackers on the other side of the world could use cellphone-based malware to remotely access any data they want, using the electromagnetic waves emanating from computer or server hardware, with no need for an Internet connection.

The hack isn’t new, according to Prof. Yuval Elovici, head of BGU’s Cyber Security Lab. The technique was used to attack Iranian servers in the Stuxnet hack attack. What’s new is the use of a cellphone to do it.

The Iranian network targeted by Stuxnet was an air-gapped one, connected only to local computers, with no external connection to the Internet. The virus infected the servers controlling the Iranian nuclear program’s centrifuges, “choking” them until they ground to a halt. It was, many experts believe, physically transferred to the closed network via a USB flash drive. The attack described by Elovici is light-years ahead of Stuxnet, because no physical contact is required to compromise a system.

Even if you don’t think your computer is connected to anything, it sends electromagnetic or acoustic emanations from its hardware. The NSA’s (National Security Agency) TEMPEST program uses special devices to pick up data from computers and servers via leaking emanations, including unintentional radio or electrical signals, sounds, and vibrations from hardware such as video monitors, keyboards, network cards and memory chips.

Each stroke on a keyboard, for example, transmits an electrical signal that runs through a computer’s processor and shows up on the monitor, emitting electromagnetic waves. Since each letter is unique, each key gives off a different frequency wave. If a hacker can capture those waves and reconstruct them, he could figure out what usernames and passwords were used to log onto the network.

How could a mobile phone be used to hack into an air-gapped network? In a take-off of an email phishing attack, a hacker could send an unsuspecting employee in a sensitive installation a text message that looks legitimate, but contains a link to malware that surreptitiously gets installed on their cellphone.

Once the malware is on the phone, it scans for electromagnetic waves which can be manipulated to build a network connection using FM frequencies to install a virus onto a computer or server. Elovici’s team has demonstrated how this is done with computer video cards and monitors. With the virus installed on the system, the phone connects to it via the FM frequency, sucks information out of the server and uses the phone’s cellphone network connection to transmit the data back to hackers. All that’s needed is physical proximity to the system. The team said that one to six meters is enough.

Elovici and his team demonstrated this technique to President Shimon Peres during his visit to BGU’s Cyber Lab last month.

Right now, Elovici said, there’s little that can be done to prevent this kind of cyber-attack other than turning off the phone. As that is not a practical solution in this day and age, his team is searching for other solutions. It’s a major security risk, he said. Until a solution is found, that risk will only increase, as news of the hack spreads in the hacker community.

How to Use Social Network 

Effectively: Enhance ur Time 

Productivity

Like Twitter, Instagram and many other social media platforms of its type, Facebook is often vilified for being a major source of procrastination and fostering time-wasting behaviors. And let’s be honest – it’s not entirely untrue! How many hours have we wasted, shamelessly spying on our friends’ and relatives’ lives (oh, is that just me, then?) or falling down the mesmerising rabbit hole that is Farm Ville? or CandyCrush,or  Poker Watever it may be, You know the drill: you open a browser, innocently intending to double-check the date of that hot event you were invited to, and bam - that’s it, four hours of your life, gone! It’s okay – you’re not alone and happily, there are ways of not only minimizing Facebook’s inherent time-suck effect, but also (and this is the exciting part) using this popular social media network as a means to educate yourself, get inspired and meet incredible people. Read on to discover 5 tips that will change the way you use Facebook – forever!

Often, the reason why we waste so much time on Facebook is simply because we follow too many people and subscribe to too many Pages! With an average of 250 Facebook friends per U.S. female and an average of 1,500 posts eligible to appear in a user’s feed every day (data from Digital Media Ramblings), it isn’t hard to see why so many of us get sucked into the black hole of social media procrastination. The simplest solution to this predicament is to cut down on the number of people in your friends’ list and unsuscribe from the Pages that don’t add value to your Facebook experience. Consider this: how many of your Facebook friends do you actually speak with on a regular basis? Whose status updates do you find yourself repeatedly ignoring? Which posts do you systematically scroll past when they pop up in your Timeline? Ask yourself: is it worth keeping these people and Pages around if you don’t enjoy what they have to offer anymore? If the answer to that question is no, then cut them out! and Subscribe only the fruitefull and Inspiring Ones! 

Ever wanted to filter out an overzealous friend or relative’s Facebook noise without hurting their feelings by unfriending them? You can! All it takes is a simple, three-step process: 1) locate a post from this person in your Timeline and click the little arrow in the top-right corner. This will cause a drop-down menu to appear. 2) Click “I don’t want to see this.” When you do this, that specific post will be hidden from your Timeline. 3) If you want to take it further and radically diminish the number of posts from that person, click “See less from [name of the person]“. This will ensure that you see fewer posts from that person, without removing them from your friends’ list!    [ Dont try It on  Our Page... ;) ;) ] 

Most Imp: You can do this with Groups and Pages, too! All you need to do is follow exactly the same three steps. and I bet U ,u will have Saved Enough of ur usefull time!

Now that we’ve learned how to minimize distractions and noise on our Timelines, it’s time to look at some of the positive aspects of the social network! As we primarily use Facebook for staying in touch with our friends and relatives and keeping abreast of the latest developments in each other’s lives, we don’t necessarily realize that Facebook is a brilliant learning tool, too. Indeed, whether you’re trying to learn a new language, beef up your professional skills or simply be more inspired and motivated on a daily basis, chances are there’s a Page for that! Example we have page at fb.com/easyhackblog. which enables all people to open their Views on New way of Computer Security, and tricks. and as everyone of us Knows this is the most usefull topic to learn in The Digital World that today we are living in!

 Bonus: Now that you have either unfollowed or filtered the notifications of the people and Pages you’re no longer interested in, the content from the Pages you do want to see will be much more prominent on your Timeline!

OfCource! You can learn and get inspired on Facebook, but guess what? You can also meet interesting people and network with them!  Just as there is a Page for your every learning need, there is likely also a Group, too. Consider this: if you’re a solo entrepreneur, it can be difficult to find like-minded people in your entourage and mingle with others who get what you’re going through. Joining a Facebook Group or Page like EasyHack where people like you hang out is a brilliant way to get advice and support on issues that might trouble you, or simply make new friends! Bonus: If you’re an online business owner, Facebook Groups are a great place to get feedback on your products or services and to find prospective clients! Think about it: these are all people who share the same issues and predicaments. They likely also operate in the same industry as you. Therefore, they are probably the best equipped to give you advice on what you’re offering, and who knows – they might be so into it that they want a piece of it, too!

Whether you have ideas of your own that you think would be helpful to others, or a business that you would like to get more eyeballs on, Facebook is a brilliant option for sharing your views or your products with the world! If you’re operating on a non-profit basis, create a Page that your friends, relatives and fans can follow to get the latest news that you want to send out. This makes life easier for both you and for them: for you, because it saves you the trouble of having to contact people separately about a given topic or event; for them, because all the people who follow your Page can get the information they need in one place. Easy! If you’re a business owner and are willing to spend a little time and money, Facebook can be an excellent way to promote your products and build a solid online reputation. The social network’s advertising system is extremely well thought-out, and will enable you to get your posts out to the right audience for a reasonable price. Having a company Page will also give your clients and fans a rendez-vous point to keep up to date on your latest news. In short: Facebook can work hard for you, if you let it: simply filter out the content that doesn’t interest you and follow the Pages and Groups that are useful to you! Don’t be afraid to take advantage of its many perks for your personal life and your business.
