When I first heard about the "fake cell phone tower", I thought to myself, hold on. Got something like "fake" cellular towers? ! ? Why would anyone want or use fake cell phone towers?
Bhuel, freagair na ceisteanna seo: Sea, tá go leor túir fón póca falsa ar fud an domhain mar is féidir leo go leor faisnéise pearsanta a bhailiú fút féin agus faoi do ghuthán cliste. Ceann de na codanna is measa, ní bheidh a fhios agat féin ná ag do ghuthán go bhfuil sé ag tarlú. Uafásach, tá a fhios agam.
As with most technologies, "fake/rogue/unregistered" cellular towers can be used for valid or malicious purposes. However, for better or worse, we should all be aware of and pay attention to this growing data interception.
Cad is túr cealla bréige ann
First of all, fake cell phone towers have many different names: Stingray, Dirtbox, IMSI Catcher, etc. The government purchased fake towers from large contract organizations such as Boeing and Harris Corporation for hundreds of thousands of dollars. However, the fake tower can be made and used effectively, and the price is less than one thousand US dollars. The more you spend, the greater your ability and scope, but the key is that you can start invading people's lives with the least investment.
Secondly, fake cell phone towers perform similar tasks, deceiving phones (or other cellular-enabled devices) to connect by broadcasting stronger signals than other surrounding cell towers. Smartphones are designed to connect to the strongest signal available to reduce power limitations and optimize the user experience. Therefore, if the fake tower broadcasts a stronger signal than the legitimate tower, your phone will automatically switch-creating a perfect "man-in-the-middle attack"-to collect data from the phone before transferring you to the legitimate tower. You never know it even happened.
Seo a leanas éifeacht amhairc a phrionsabail oibre:
Now that you understand how fake towers work, let's take a look at what they can collect.
Cad is féidir le túir fón póca falsa a dhéanamh
As we outlined, if you connect to a fake tower, it's between your smartphone and the legitimate tower that collects data. This usually includes eavesdropping on conversations. Dialogues between potential criminals, business dialogues, and even sensitive government dialogues.
Fiú mura bhfuil tú ar ghlao agus do ghuthán ceangailte, baileoidh an túr na sonraí go léir a théann tríd; Teachtaireachtaí téacs SMS, ríomhphoist, sonraí feidhmchláir, etc.
The fun doesn't stop there. Even if you do not make a call or transmit any data, fake cell towers can actively attack your smartphone, insert malicious code, and fundamentally control your phone. Therefore, even if you disconnect from the fake tower, the installed malware will continue to transmit data about you and your activities. This is called a remote radio frequency hacking and is very worrying.
Cé chomh dóchúil is atá sé nasc a dhéanamh le túr bréige?
Athróidh nascadh leis an túr falsa ó dhuine go duine, ach má tá cónaí ort i gcathair mhór nó má thaistealaíonn tú thar lear, tá tú i mbaol níos mó.
First, from publicly available information, Stingrays is being used all over the United States. This secret technology is only legally available to the government, and they don't need to report when it was purchased, used, or how it was used.
Second, if someone has the technical prowess and doesn't care about breaking the law, then a simple online guide can be used to create a fake tower. These "fake" towers will enable attackers to collect and learn a lot of sensitive personal and professional information from people connected to their towers. If someone clicks on your smartphone, you can make your brain frantically process all the information that may be collected. Commercial information, legal discussions, political opinions (yes, the country knows your political opinions on the phone), and personal information may be used for blackmail (parenting, children's social comments, etc.).
Ar an tríú dul síos, is cluiche uimhreacha é túir falsa a úsáid, mar ba mhaith leat dul áit a bhfuil cónaí ar an gcuid is mó daoine agus ag taisteal. De ghnáth cuirtear túir bhréige i scrogaill mar aerfoirt a dtugann go leor daoine cuairt orthu gach lá. Mar sin féin, de réir tuairiscí, tá túir bhréige curtha isteach ar an aerárthach freisin, rud a thugann pointe amhairc níos leithne do bhailitheoirí sonraí.
An dtabharfaidh mo ghuthán nó an rialtas cosaint dom?
I hope you haven't thrown your phone out the window, and yelled and blasphemed! But it does get worse.
Ar an gcéad dul síos, mar a luadh muid, ní bheidh a fhios agat go deo an bhfuil tú i do úinéir nó i dteagmháil le túr bréige, nó má tá do ghuthán faoi ionsaí (is aoibhneas an t-aineolas!). Is gléasanna tráchtála iad fóin chliste agus níl ardghnéithe slándála acu chun ardionsaithe a shainaithint, a chur san airdeall agus a chosc (amhail túir bhréige).
Ar an dara dul síos, níl beagnach aon mhaoirseacht ar úsáid agus monatóireacht na teicneolaíochta seo. Sea, tá roinnt smacht inmheánach ag an rialtas ar conas na gléasanna seo a úsáid chun sonraí a bhailiú, ach ní féidir le haon rud stop a chur le coirpigh. Níl an rialtas ag lorg a gcuid comhartha, ná an chuideachta teileachumarsáide. Is é an pointe go bhféadfadh aisteoirí mailíseacha in aice le do theach nó oifig a bheith ag baint úsáide as an teicneolaíocht seo agus nach bhfuil mórán aitheantais ar an ngníomhaíocht. Mar sin, ach amháin má theastaíonn uait na milliúin dollar a chaitheamh chun ardchóras a cheannach a aithníonn comharthaí túir fón póca mailíseach nó trealamh tí a thógáil, táimid go léir ag fanacht le comhartha cumhachtach mailíseach chun ár bhfóin chliste a nascadh.
Cad is féidir liom a dhéanamh chun mé féin a chosaint?
Cé go bhfuil an túr falsa an-fholaithe agus an-ionsáiteach, tá céimeanna ann ar féidir leat a dhéanamh chun sábháilteacht a fheabhsú.
Ar an gcéad dul síos, cuir in iúl duit féin gurb é na rioscaí atá i gceist an bealach is fearr chun túr fón póca falsa a chosaint. Tá cumhacht ag an eolas, agus cabhróidh sé seo le do shábháilteacht phearsanta a bheith san airdeall faoi bhagairtí féideartha.
Second, reduce or eliminate your RF signal. Simple, free solutions, such as turning off your cell phone when crossing a traffic artery, are a good start. For example, please turn off your mobile phone when you arrive and pass through the airport, especially the international terminal. But keep in mind that turning the phone "off" will only reduce its RF signal, and will not 100 percent avoid attacks. If you need additional protection, you can purchase an RF shielding solution, such as our Privoro Privacy Guard, to eliminate all RF radiation from your mobile phone. Please note that if you purchase an RF solution, you will need at least 110 dB of RF attenuation to effectively avoid false towers. There are many solutions that claim to do the job, so research before buying anything.
3. Criptigh na sonraí tábhachtacha go léir; comhaid, trácht Idirlín agus do ghuthán. Trí na sonraí a chriptiú, beidh sé níos deacra d'ionsaitheoirí na sonraí a bhailíonn siad a thuiscint. Bain úsáid as réitigh shimplí mar chliaint VPN (ná húsáid an leagan saor in aisce), HTTPS uileláithreach, agus feidhmchláir mar Signal le haghaidh glaonna criptithe. Ní dhéanfaidh aon cheann de na réitigh seo do ghuthán nó tú féin a urchair le urchair, ach ardóidh sé bacainní iontrála.
The last point of this article is to stay vigilant and consider what you discuss and send via cell phone towers. As you learned today, whether legal or illegal, someone may extract information from your phone, conversation, and surrounding environment without your knowledge. You never know whether the information was captured by a third party, and the third party may use the data for their benefit or at your expense. Our "always connected" technological lifestyle can be easily read and "always monitored". Stay safe there.
