Read More , but many still hate it. And a big part of that is how “discoverable” you are.

Unfortunately, this means a lot of myths are now outdated and wrong. Read More that changing your Bluetooth to “non-discoverable” protects you. Sadly, hackers are smarter than that.

This has led to Bluejacking — that is, sending malicious content to your phone via Bluetooth, including eavesdropping software, and malware. In 2012, for instance, the security suite firm, Kaspersky Labs uncovered Flame, malware used in places like Israel, Sudan, and Syria but most widely found in Iran. Due to its considerable file size (and the fact it took at least two years to be discovered), Kaspersky claimed it was:

“[O]ne of the most complex threats ever discovered.”

It used Bluetooth to search and download contact names and phone numbers from not only the user’s device but also any nearby Bluetooth-enabled smartphones. Furthermore, after installation, the malware could record calls, including Skype This Trojan Malware Might Be Recording Your Skype Conversations This Trojan Malware Might Be Recording Your Skype Conversations If you've use Skype, you need to know about the Trojan T9000, malware that records your conversations, video-calls and text messaging, and is virtually undetectable to security suites.

That shows Bluetooth’s potential for spying on you.

What can you do? Being aware of the problem is a good first step, especially if you naïvely think iPhones don’t use Bluetooth. (I’m not criticizing: I was unaware of that for some years too!)

One line of defence, of course, is a solid four-digit passcode Should You Use a Fingerprint or a PIN to Lock Your Phone? Should You Use a Fingerprint or a PIN to Lock Your Phone? Should you secure your phone with a fingerprint or a PIN? No one is likely to guess your fingerprint, but is it really more secure? Could a PIN be more secure? Read More . Don’t go for something obvious. Your best bet, though, is turning Bluetooth off, preventing hackers from getting into your device. “Non-discoverable” might seem like a safe option, but it’s much better if you simply turn Bluetooth on solely when you intend to use it.

Yes, Your Battery Can Spy On You

This sounds utterly bizarre, but it’s come to light, relatively recently, that your smartphone battery can be used against you.

10190121406_52459e977c_z

It started with good intentions: websites and apps can request information automatically from your smartphone about how much battery you’ve got left; if it’s low, the site can then present a lower-power version of itself so it doesn’t burn up your much-needed charge.

But research, collated from a study of the top 1 million sites, suggests that some services can use that data to spy on your online activities and bypass privacy measures you might be employing already, like using a Virtual Private Network (VPN) 8 Instances You Weren't Using a VPN, but Should've Been: The VPN Checklist 8 Instances You Weren't Using a VPN, but Should've Been: The VPN Checklist If you haven't already considered subscribing to a VPN to secure your privacy, now is the time. Read More . It’s a scary thought because there’s very little you can do about it.

The immediate concern was that the protocol can be carried out without the user’s permission, but that didn’t set off too many alarms as it was solely to send data on the estimated time until the battery dies, and how long it’ll take to charge. But combined, these can form an identifier, especially as the information reloads every 30 seconds. That means that two seemingly-separate data sets (through private browsing 4 Ways You Can Be Tracked When In Private Browsing 4 Ways You Can Be Tracked When In Private Browsing Private browsing is private in 99% of cases, but there are many ways in which it can be circumvented, thanks to browser extensions and hacks. Some of them don't even need all that much work. Read More or the aforementioned VPN) can be linked, so no matter how you try to evade detection, your browsing can be tracked.

Visiting the same site frequently means your cookies can be reinstated, even if you’ve cleared them, a practice known as respawning; doing it for an extended period — those sites you visit every morning before your start work, for example — can result in a more definite unique identifier being assigned to your device.

This might not seem too troubling (after all, we’re used to being tracked online by all sorts of services, including those Facebook sharing buttons It Doesn't Matter If You're Not On Facebook: They're Still Tracking You It Doesn't Matter If You're Not On Facebook: They're Still Tracking You A new report claims the Facebook is tracking people without their permission. It doesn't matter if you don't use social networking service: they're still watching you. What can you do about it? Read More ), but there are real-world consequences. A notable one is Uber, the popular taxi company, which denies any questionable business techniques but admits potential is there to charge its customers more when their battery’s nearly dead. Uber’s head of economic research, Keith Chen says:

“When your phone is down to 5% battery and that little icon on the iPhone turns red, people start saying, “I’d better get home or I don’t know how I’m going to get home otherwise.” We absolutely don’t use that to push you a higher surge price. But it is an interesting psychological fact of human behaviour.”

What can you do? This is a difficult practice to battle against. Data is collected if your battery’s low, so keeping it topped up is a good move, as is avoiding apps that sap it Avoid These iPhone Apps for Better Battery Life Avoid These iPhone Apps for Better Battery Life Killing background apps won't save your battery — in some cases you'll have to completely avoid an app in order to stop it from draining your smartphone's energy. Read More . Otherwise, you might want to consider only visiting sites you go on regularly on one specific device (maybe your work’s PC) so your smartphone isn’t tracked relentlessly.

Smart Spying?

Subterfuge is the ideal method for tracking, at least to those who want as much of your private information as they can, so spreading the word certainly helps. Nonetheless, surveillance will always evolve, and these three examples highlight how smart services can be.

Which other tracking methods surprise you? How do you fight against Big Brother?

    I second, third and fourth anonymouse1's sentiments.

    The increasing online tracking trend may not "seem troubling" to the lemmings that blithely and eagerly hand over their private and personal information in an uncontrolled urge for just little more convenience. However, this trend is VERY TROUBLING to anyone who values their privacy and security. Today's amount and methods of tracking make NKVD, KGB, Stasi, Gestapo and others of their ilk look like rank amateurs. I used to believe that there will come a day that every newborn, pursuant to laws passed by governments, will be implanted with an RFID chip so they can always be tracked. Now I see that such laws are unnecessary. We VOLUNTARILY carry on our persons devices that allow anybody and everybody to track our every move and spy on our every activity. We willingly give up our private lives so that we can more conveniently post inanities on social networks and/or play Candy Crush, Angry Birds or Pokemon GO more easily.

    In response to the author's aforementioned statement, "This might not seem too troubling (after all, we’re used to being tracked online by all sorts of services, including those Facebook sharing buttons), but there are real-world consequences,"----I wholeheartedly disagree with that particular statement.

    I'm not used to being tracked because I do everything within my power to protect that which rightfully belongs to me-------my Personally Identifiable Information. I don't use privacy-violating services such as Facebook nor Skype, nor have I hopped on the Win10 anti-privacy-train to it's headquarters in Redmond, Washington, USA. And there are many millions more citizen's just like me whom also draw this boundary-line. It is a personal boundary that should never, ever be crossed we have every right to be angry about it and to reject this type of abuse and exploitation of our information every chance we get!

    To suggest that this privacy-violating trend is not too troubling is akin to throwing the 'log' of our identity on an open fire and acting as if it's of no consequence whatsoever. We have an unalienable right to protect whom we are! Corporations should not get a free pass to blur these boundaries of ours simply because they can make money by doing so---and they should never get a pass to infringe upon our human rights now, nor at any time in the future.

    A line needs to drawn which prevents this from happening while at the same time protecting our rights and our identities. These corporate thugs aren't going to draw that line, which is why it is up to us to champion our privacy at every possible juncture---lest we give up and let these corporate creeps destroy the very fabric of what makes us human in the first place.

    We have an innate need for privacy as human beings. Just because companies are acting irresponsibly with regard to our own identities, does not mean that we have to accept it, nor that it is something that we should get used to-------ever!

    [ https://www.schneier.com/essays/archives/2006/05/the_eternal_value_of.html ]

    Privacy is our fundamental right as human beings and a necessary component of true security. Those whom tell you that privacy must be sacrificed in order to provide security are lying to you for the sake of insane profiteering off of whom you are, where you go and what you do-------This is one of the greatest deceptions of our time!

    [ https://www.ted.com/talks/gary_kovacs_tracking_the_trackers ]

    These companies and their ad-affiliates get away with it because of their ability to hide behind the already obscure nature of the internet itself. Essentially, they prey upon user-ineptitude about their ability to hide their privacy-violating actions from plain sight, in order to keep us defenseless against their unethical actions of pilfering our personal information. They're able to maintain this standard of operation because they use vague---yet deceptive language in their Privacy Policies and Terms of Service Agreements, of which have been legally designed to protect their exploitation of your personal information.

    [ https://www.youtube.com/watch?v=X1F8sHjCBx0 ]

    The privacy-violating Corporations and Agencies can 'put on show' for their consumers all they want, but they're not fooling anyone! Smart people see through this veil of deception-------this egregious affront to our own lives and liberties!----Our personal freedoms and our rights to privacy!
