Edward Snowden recently revealed that the NSA has the ability to listen through your iPhone even when it is turned off. Other experts doubt this statement, but it doesn't hurt to listen to hackers who propose a way to protect your phone from unwanted ears.
Recall that Snowden was the one who exposed the US government's "secret" mass surveillance program a year ago. Since then it has continued to be news in the media with shocking facts about the scope of espionage of the National Security Agency (NSA).
In the past week offered an interview to the NBC, where he explained that you can spy on phones even if they are turned off. "Someone can turn it on remotely if it is off?»The presenter asked Snowden referring to the smartphone he used to travel to Russia for the interview. «Can they open applications? Tosomeone mind if i googled the result of the Rangers-Canadiens match last night? "
«I would say yes, to all questionsSnowden replied. «They can turn them on and use them despite being turned off"He added.
It is no news that the American agency, and they are probably not the only ones, have used mobile phones as a spy tool for at least a decade. Already 2006, the media reported that the FBI applied a technique known as «roving bug»That allowed them remotely activate a phone's microphone cell phone and listen to conversations near the terminal.
La geolocation of a person It was not a problem, thanks to the GPS. This technology has been of great help in the search for missing persons, remember that we had the belief that battery disposal the terminal made monitoring impossible, until in July of last year, the Washington Post published than "In September 2004, a new NSA technique allows mobile phones to be located, even when they are turned off.»The technology is called«The Find«, And« has been widely used in Iraq.
To eliminate this process on iPhone, you have to put it in firmware update mode (DFU), argues Eric McDonald, a hardware engineer specializing in security. In this mode, all elements of the phone are closed except for the USB port that waits for iTunes to install the new firmware. In this way, the phone's power management unit override any running software, including any type of malware designed to simulate a shutdown, McDonald says.
The following video explain step by step for those unfamiliar with DFU mode.
What sense does it make if it should be in DFU, what would its use be? Or is it just putting it in and taking it out that way?
It is not a question of utility but of choice. If you don't want to be tracked down, don't turn it off or remove the battery (ahem…) but instead put it in DFU mode.
super useful, I will do it every hour. Thanks for this fantastic news
Or you leave the phone in a drawer, which you are going to give it the same use as in dfu but also there is no possibility that you will break it.
The quality of the articles on this blog lately is amazing ...
We are common people think that NASA will be interested in spying on anyone
Be careful NASA may be spying on you to see if you qualify to be an astronaut !!!!
Oops, the NSA is spying on me! Well then, spy on me. If you are not a terrorist, a paranoid or you think you are the naughty and that is why they must be looking at you constantly, you can be calm or leave the phone alone.
Sure, NASA, yokels. NSA!
The problem is what they can do with the information in the future ... think a little now, I will not imagine this case ... right now you are nobody and you take drugs, you have women, etc .... But what if in a few years by chance of fate you become president of your country, and for some reason you are against the interests of the country in question, what do you think they would do with your information that they know about you ……….
