The DFU function in iPhone εμποδίζει οριστικά τις υποκλοπές των συνομιλιών του κατόχου του - οι οποίες μπορούν να συμβούν ακόμη και όταν εκείνος νομίζει ότι έχει απενεργοποιήσει τη συσκευή του!
Once again, Edward Snowden, the former agent of the US secret services, made revelations about the surveillance capabilities that have services such as the NSA. Snowden revealed in a broadcast of the American NBC network that there is a possibility of trapping the iPhones known to be owned by tens of millions of people around the world. With this trap, someone can eavesdrop on what the device owner is talking about, even when their device is turned off! After the revelation, experts were quick to suggest a way to prevent this trapping of iPhones.
The implant
The trap that Snooden referred to is by a technique known in the world of tapping with the term "implant". The implant referred to by Snowden works in such a way that the owner of the trapped device thinks that it is switched off while in reality it is in (hidden) mode and receives commands such as to activate the microphone. So the concealer can listen what the device owner discusses.
Το εμφύτευμα έχει την μορφή λογισμικού και μπορεί να τοποθετηθεί σε μια συσκευή είτε αν αποκτήσει κάποιος απευθείας πρόσβαση σε αυτήν για να το τοποθετήσει είτε από μακριά, αν η συσκευή συνδεθεί με το διαnetwork ή μέσω του συστήματος συχνοτήτων στις οποίες λειτουργεί η συσκευή. Το εμφύτευμα μπορεί να είναι επίσης και κάποιο εξάρτημα για την τοποθέτηση του οποίου απαιτείται φυσικά απευθείας πρόσβαση στο επίμαχο mobile.
How to protect yourself
As the Snowden revelation was understandable except from discussions it also caused a lot of disturbance to the owners of iPhones. So some experts in the field of mobile phones initially rushed to confirm the former agent stating that there is indeed this security gap in iPhones but at the same time giving a solution. They even showed a way in which the function of the implant is hindered.
The iPhone owner must initially connect the device to a socket or USB port. Then you must hold down the power button of the device. After three seconds holding down the power, press and the home button. Keep both keys pressed for ten seconds. First leave the power key while still holding the home for about 15 seconds. The DFU mode will be activated, its conventional use is related to device software upgrades but, according to experts, it also blocks specific implants.
