The bougie box that is not 315 exposure again is distressed, it is far from so return a responsibili_News

This year 315 exposure an unbeknown gray industry: Intelligence annoys phone and the bougie case that probe address of mobile phone MAC stealthily.

The bougie box that is not 315 exposure again is distressed, it is far from so return a responsibility

Then, everybody begins to study random MAC address is mixed in succession prevent harass a telephone call.

You may have seen this piece of picture a lot of times, and accompany my millet XX, my China have for XX, my XX also does not have this kind of word, lane is popular in a state of anxiety another mist water

We will explain below:

MAC address is the hardware code that the net blocks, be equivalent to the Id that the net blocks, address of mobile phone MAC is the Id that wireless net of mobile phone WiFi blocks, grow commonly such,

With 16 show into tabulation, 6 byte, detailed sees mobile phone WiFi is installed

When equipment couplet net, road by implement emissive WiFi signal, signal of WiFi of mobile phone scanning, at this moment the MAC address of the mobile phone can be mixed first road by implement MAC address butt joint affirms private parts portion, the butt joint is finished, can input password join equipment.

Bougie box follows a path by implement same place also is transmitting WiFi signal at it, because this mobile phone joins when bougie box, can be walked along by pilfer MAC address.

Different place depends on, road by implement save only already joined the MAC address of equipment, bougie box saves all MAC addresses that it scans, very scampish.

But when I see a story very interrogative:

Although MAC address is obtained easily, but how does the big data that these companies distribute MAC address with Yu Pi come?

This company still claims, their company has the information data of 600 million user of countrywide, include all sorts of information such as date of user mobile phone, big data of the Mac address that wants to will be received only and company system tiring-room undertakes matching, can change the mobile phone number that gives an user.

Through understanding, so these big data come from the App that we use at ordinary times!

Almost all App can ask to read the WLAN that takes a mobile phone and identity at the same time (IMEI strings together date) attributive, and we use mobile phone number be registered and log onto App.

If these store the information in App by divulge innocently of purpose, MAC address, IMEI strings together date to be equal to exposed completely.

If ash produced an organization to buy these information, the IMEI that inquires correspondence very easily through MAC address strings together date, repass IMEI strings together date to obtain the information such as number of user mobile phone.

So elaborative, really painstaking you

So, stem from fountainhead MAC address is detected, besides do not go out WiFi, be explored every time namely or when join WiFi, let a mobile phone make random MAC address.

But, when exploration WiFi and WiFi join, it is two kinds of circumstances.

The random MAC address before exploring, was equivalent to hand mechanism going up to divulge " the door " .

And go up when our join after unidentified WiFi, MAC address or meeting are exposed, when adding WiFi to join so random MAC, namely " the door again lock " , double defend.

Android begins from Android 8.0, the metropolis when exploring new network uses random MAC address, android 9 is same also, the risk is higher " the door " problem, had solved.

When this switch calls developer mode Wifi join random MAC, stage test hardware uses convenient developer.

Those developer mode on the net look do not have switch to leave those who scold, if it were not for was not cleared up, android 8.0 of if it were not for has with setting, and bougie box is fraud of a masses far from, the individual information that spreads in mill website and App as a child directly just is!

Finally, say to settle way for us:

1.Android 8.0 and above set equipment user, basically need not be explored before afraid join, on Android 9, castrate of may certain custom-built ROM the random MAC function after join.

But this switch is opened safer, developer mode arrives if having (setting, about the mobile phone, the dot presses version date 7 times) in open.

If 2. is Android 8.0 have in order to set or do not have this option, via this one battle, manufacturer people this function can increase in be updated next time, also need not anxious

It is OK also that 3. hand uses modification MAC address, but need Root attributive, use rise to also be bothered a bit (this App has define) , the later development end such as the user with appropriate condition has been taken oneself.

4. to the most miserable circumstance: Android 8.0 is the following, the system was not updated, also do not have Root, we can solve this problem from terminal only.

Chinese mobile user: Dial 10086 or send a short message " KTFSR " prevent to the 10086 intelligence that can open shift freely annoy a service, but need opens VoLTE first (send short message KTVOLTE to come 10086) , and have district restriction.

Debut, can have a short message / small letter (green aegis defends pilot Guan Wei) clew:

Chinese UniCom user: Send short message KT to come 1065587 also can debut freely prevent annoy a service, emmm... still have additional requirement

Chinese telegraphic user? I am sorry... it seems that telecommunication is done not have so active, everybody or support XX mobile phone steward or the system takes oneself prevent annoy intercept to serve
