From the theft of $230,000 from ShapeShift to the DAO hack, large amounts of cryptocurrency can be stolen through security breaches if the owner does not take the necessary safety precautions.Of particular vulnerability are mobile devices, which can be subject to a host of attacks through apps that are spyware in disguise.CoinTelegraph interviewed Gary Miliefsky, CEO of cyber-security firm SnoopWall, about the security risks facing mobile device Bitcoin wallet users.CoinTelegraph: Bitcoin smartphone wallets: how secure are they?Gary Miliefsky: Smartphone wallets are completely insecure.There have been over 500 million downloads of emoji keyboards: keyloggers, spyware disguised as friendly emoticon keyboards.When you startup your smartphone wallet the first time, you may enter bitcoin info or add username/password credentials.These are shipped off to criminal servers remotely because of this kind of keyboard malware.Many of these QR code and barcode scanners come from legitimate sources like eBay, Zxing, Scan Inc, and DroidLa.

Despite this, SnoopWall still deems many of them voluntary creepware.The reason for this is that many have intrusive permissions that allow them to geolocate you, read your contacts, access USB storage, read your call log, make phone calls, and even record audio.Most of these permissions are legitimate, as most of these apps allow the user to generate information like phone numbers, contacts, and locations as scan-able QR codes.CT: Is this only a concern with aftermarket keyboards, or does this happen with standard iPhone and Android keyboard apps?In addition, on android just about any app can spy on you.For example, our favorite flashlight apps (third party) spying on you while you take a picture of a QR to scan a bitcoin, etc. Android more risky than iPhone.CT: What are some best practice tips for Bitcoin smartphone wallet users?CT: So you would recommend against doing Bitcoin transactions over wifi GM: Too risky to easily man in the middle.They call this EVIL AP and there are others, but it's very easy.

Unless you understand what rev of TLS/SSL you are running, if the wifi is encrypted, if you trust the wifi (not spoofed by hackers)...lots of issues.CT: You mentioned QR code scanners and flashlights being dangerous.Are there any that are secure to use?GM: Only those that have OPEN Source code or don't use internet or other ports.You can dig through them online using this criteria.My team made 'privacy flashlight' to prove it and it's 200 kilobytes open source, whereas the average flashlight is 3-10 megabytes!litecoin account balanceJust look for permissions used, maybe pay for one from a trustworthy party.cnbc investigation bitcoinI even think Symantec figured this out and made a 'secure' QR reader.bitcoin doaCT: Is there any way to get spyware apps taken down, or is it simply a matter of "buyer beware"?bitcoin sto je to

I've tried...no one listens.Apple, Google, Microsoft - they like their (dirty little secret) advert libraries.[They] recompile your app with their spyware libraries (oops, I mean consumer analytics) and you can do anything!Just share the 'ad revenues' even if none, while you pleasantly steal PII.CT: What got you into the privacy protection game?Editor’s note: Contributor Kevin Cruz writes for BitcoinMagazine and so he knows a few things about Bitcoin.bitcoin online rechnerBut with the help of a BTC to cash service he tried to live for weeks using only bitcoin.bitcoin mining nvidia geforceI write for a living and sometimes people pay me in bitcoins.I’m aware that I’m being paid in a currency that hasn’t reached mainstream adoption, but I keep collecting them to see what happens.Last month, while writing a book review late in the night, I got a phone call from an unknown number.

It was a guy named Cyril Houri from a Bitcoin company called Brawker.He had a proposition that blew me away: he would help me to live solely on bitcoins for a month.I was going to be his guinea pig.Brawker allows people to buy and spend bitcoins by matching a bitcoin holder with a credit card holder; The credit card holder pays for a good/service and receives the bitcoins in return.Effectively, this provides a platform for  people to buy bitcoins.More important for you to know while reading this story: the platform  allows people to use bitcoins anywhere, with a considerable discount.I didn’t know where I would spend them,  or where this journey would end, but I accepted.This was an opportunity I could not turn down.It was time to make some magic.I used Brawker to buy most of the things on this journey, and I’ve indicated the instances in which I used another method.I was living at my aunt’s apartment in New York City where I paid no rent or electricity, and travelled using public transportation (no need to buy gas).

The first thing was to take care of me my cell phone bill.I went online and purchased a refill card for my cell phone company.This was done by creating an order on Brawker, posting it, and having someone fulfill it.Within an hour, I got a pin number in an email and paid my cellular provider.Next was food, which is one of the larger expenses.To eat, I purchased a Whole Foods gift card and restocked the whole fridge with organic food.One of the bigger mistakes I made in life was going to college without knowing what I wanted to study.All I got out of it was debt.It’s a mistake I pay for to this day.Every first of the month, money is taken out of my checking account.But  this time around, I processed my loan payment a little differently.Using Brawker, I sent someone  my bitcoin and they paid Sallie Mae or whoever it is now with their credit card.I had officially finished paying all of my monthly expenses.I still had a considerable amount of  money leftover after paying my loan, so I decided to get creative.

I’ve always loved creating music.Luckily, we live in an age where we can make quality sounds with small, mobile devices.I bought a MIDI keyboard and have been jamming since.Another one of my dreams was having some farmland.The previous month while on a road trip,  I visited  a friend’s farm in Ann Arbor Michigan  that runs on bitcoins.This patch of farmland is the first of its kind.While there,  the idea of leasing land in bitcoins seemed unreal to me.I had the BTC so decided to do it, and now my crops are currently being taken care of by interns.While online one night several nights later, I found a dentist in New York City that accepts bitcoin.I made an appointment for a basic cleaning.When I got to her office, the dentist promptly began cleaning.Suddenly, after several minutes, she  told me that she was worried for me.“What is it doc”, I asked.“Am I losing my teeth?” “No, but your wisdom teeth need to be urgently removed.They’re growing sideways.” Recalling terrifying stories my friends had told me about their wisdom teeth removal, I kindly refused the wisdom teeth extraction.

She finished up the cleaning, and I paid for the cleaning with my smartphone’s bitcoin wallet by scanning a QR code on a slip of paper handed to me and inputting a dollar amount.I pressed “Confirm”, then I was off.Getting my teeth cleaned In NYC I now had a million-dollar smile.The following night, while walking to a bitcoin meetup, and I met a beautiful girl on the streets of the Big Apple.I was in a rush to get to my meeting, but we had a brief conversation in which I jotted down her email.After texting and learning about each other for a few days, we went on a romantic date at a wonderful Italian restaurant, Aperitivo.We shared smiles, intriguing conversation, fine wine, and luxurious cuisine at a candle-lit table.After we finished eating, I whipped out my smartphone.I  opened up my bitcoin wallet, and scanned a QR code on an employee’s cell phone.By pressing “Confirm” on my phone I paid for the meal, tipping generously.Before I could leave, however, another patron, who had witnessed my bill-paying tour de force, asserted that he would not be convinced that Bitcoin was real until he saw more people using it, like me.

He had a good point.I dropped my date at the train station and kissed her goodbye.After a week into this experiment, I began to notice that my supplemented income was causing stomach pudge.Frequent visits to my packed refrigerator were causing me to packing on pounds.I wanted to do some yoga.After looking online for a while I found a Bikram Yoga studio close to home in Harlem.For every day of the next week, I  spent 90 minutes a day in a hot room doing challenging body positions and sweating my ass off.Being a fairly simple fellow, and having treated myself quite well already, I ran out of ideas.I thought about everything from visiting a gun range to going skydiving.I kept thinking back to the dentist office.“What would be worse?” I asked myself.“Botched extraction or sideways molars that could crush all of my other teeth together?” After a brief deliberation, I made an appointment at the dentist, and got my wisdom teeth surgically removed.I regretted the decision immediately.

Although the surgeon did a what seemed like a reasonable job, the pain was excruciating.Shortly afterward, my cheeks inflated and I was in horrible discomfort (I found out bitcoins would not cover the prescribed pain meds, which I would have refused anyhow).I was extremely irritated and it was all Bitcoin’s fault.It seemed like I had signed myself up for a special kind of psychological torture.For an entire week I couldn’t eat any of the food in the fridge or attend yoga classes.With my facial deformity, I pushed aside the thought of finding another date.While strolling along Times Square, I saw a glittering sign promoting Aladdin: The Musical on Broadway.A strange impulse told me I had to see it, so I bought a ticket.The show was unforgettable.I was amazed at the fact that such a talented group of individuals could come together to create such an incredible spectacle.That night, I got home quite late.Laying in bed, I got an email from Jeremy Gardner, Executive Director of the College Cryptocurrency Network.

Always up to something interesting, I knew to open the email immediately.“Yo K. Cruz,” he wrote me, “I’m hosting the first ever Bitcoin conference in Disney World tomorrow called Coins in the Kingdom and I’ve got a ticket for you.Come through.” There are worse ways to spend bitcoin than on a last-minute trip to Orlando.So I booked a flight and flew across many cumulus clouds to Disney World to spend a week in my home state.That is when I had my eureka moment.I jumped in the air.It’s special because of the community that this technology has created!”A huge part of Bitcoin that is overlooked is the network effect.The media constantly reports the failure of centralized Bitcoin exchanges, drug busts, and ponzi schemes while ignoring the fact that humans are being brought together because of this computer program, and they are using their potential to try to change the financial landscape of the world.This is an unprecedented social phenomenon.I spent time at the conference listening to fascinating speakers and having thought-provoking conversations.

I also enjoyed tacos by the poolside bar.Everywhere I went, however, I could not avoid Aladdin.This caused me to think about his story.He is a boy born both poor but clever, who finds a wish-granting genie that transforms his life.By wishing for things that he believed would make him happy, he frees himself from the vicious cycle of poverty that he had always been stuck in.In hindsight, Aladdin’s genie reminds me of how this technology that everyone around me was discussing, Bitcoin, has allowed me to do the very same as this Disney character.If “money,” whatever that means, is a verifiable record that can be exchanged for goods and services, then by all means, bitcoin is real money.But paradoxically, I consider bitcoin to be more than that.It’s kind of magical.The magic of the technology exists in what it facilitates and in the multitude of problems that it solves.Writing about it has provided an alternative revenue stream, and all I need is the internet.From my personal experience, Bitcoin did more than just buy me goods and services.

Similar to the magic of love itself,  it led to both great pleasure and great pain.It’s allowed me to acquire things that I had only dreamed of three years ago, when it seemed like I had nothing.A very special thanks goes out to the kind folks at Brawker for helping on my unique one-month Bitcoin journey.Their generosity allowed me to experience what it’s like having a personal genie that used bitcoins to grant my wishes, regardless of whether the merchants accepted bitcoins or not.The extraordinary opportunity Brawker provided through Bitcoin has opened the door for more incredible opportunities, eye-opening experiences, and has since then catapulted me to many cities around the world.Yes, there are volatility issues with bitcoin as a currency.It’s not currently the easiest thing to use.But the fact this is the first invention of it’s kind and it still has value is a feat in itself (1 BTC= 350 USD  as I’m writing this).Services like Brawker are making using it on a day to day basis a feasible task.
