Hear easily made
Millions telephones are uncertain
Researchers of the technical University of Darmstadt proved Luxembourg and the chaos computer club to the university together with the building house university Weimar, that many cord lot telephones with simple means can be heard. The legislator sees at present no action need. It gives in Germany approximately 30 million cord lot telephones.

The safety gap is actually already since beginning of the yearly admits (there were to 01.01.09 a short report in the messages), but now only become correctly public. As far as I know, also the necessary programs are to already circulate. The Tool is to also permit it to telephone at strange expense. That weighs my opinion then even more heavily than the hearing uncertainty. Like now however the policy reacts is m.M.n. very negligently.
A WLAN e.g. must as per. Court decision (OLG Duesseldorf, Az. I-20 W 157/07) by the user to be protected, so that abuse is dammed. Therefore it is irresponsible if the manufacturers do not react and come from politsicher side no pressure. However it will require with difficulty payment of damages from the manufacturer to, since one probably is in the burden of proof.
The question is, how is rated before court, if e.g. 0900er-Nummern to be called, which however the subscriber did not select. Problematic is naturally also the Telefonbanking. If someone that password hears, he knows the account empty spaces.
Edit: nunja, if the discussions about a telephone system (e.g. ISDN) run, can also usually the discussion data be called up. In what respect have before court the conclusive force, is times undecided. If the discussion data are not manipulatable except the total delete function, it might not at all be problematic there times soooo.
@mightyEx: This judgement is quite disputed. There are evenly none gesetzl. Obligation for coding. You e.g. are. also, your Blumentppe does not obligate on the Terasse festzudbeln, so that none can kill thereby someone and you become the Mitmrder.
The entire Mitstrerhaftungsproblematik appears to me as result of good lobbying of the music industry. Unfortunately this legal interpretation is handled different also still everywhere.

what do you want to prove thereby? bestensfalls nevertheless probably that the telephone calls were actually led across your connection, because if someone chops your DECT telephone, it stands in the log file of the TK-plant of last end nevertheless simple “call from local telephone connection XY after 0900…”
A ISDN TK plant with inserted DECT station offers perhaps somewhere a log file, at least with newer devices, which no more can be programmed over a final telephone, but over the computer, a simple DECT telephone within the range 30-100 euro offers not times the option at the PC to be attached.
But even if with so a plant the log file says that it must have been a strange telephone, places itself the question, whom interests? do you want to make your telephone offerer liable for calls, which were not made unterm line only after good faith by you (it could be also your DECT Handteil which additionally announced itself there)? and even if it is recognizable that the DECT Handteil clean-chopped itself, then is it nevertheless nevertheless in keinster way the obligation of your Telefonproviders the costs of it to take over, because usually places to you no (Dect) telephone.
Good case with e.g. 1&1 with the Fritz7270 which a DECT station contained (their use is released, DECT must be not compellingly activated) insists perhaps the possibility on the telephone offerer rail money back to receive.
@Blaria: No, it would be not the telephone offerer (Provider) of it is a matter now, but around the manufacturer of the DECT telephone (where the safety gap arose). One could proceed from a lack of product. It will be only evenly difficult to prove.
With the log file geb I you right, probably hardly a conclusive force will have. Was nen mistake in reasoning of me (stop was already late

)
That to hear can be done, is well-known to me, but at strange expense to telephone? Is there a left there in addition? I doubt that it is so easily possible, from the outside, without in-booking knowledge the pin, DECT equipment.
Thus I that in such a way so far understood that it is also an error in minutes. That if e.g. means. a DECT telephone coding does not control, then that is communicated to the basis station (a kind “handshake” - mode). Because possible also a strange mobile part (thus another manufacturer) at the basis station is to be announced. This switches then quasi into the unencrypted mode. To what extent telephoning is possible, I do not know. It was mentioned however on various sides that that should have been possible. Besides is it probably like that that the researchers found also ne possibility the coded data traffic to decode. However the researchers do not want to publish this software probably.
No matter, however the fact, the DECT is uncertain is sufficient for an abuse. It would be desirable, if DECT in new version is developed further accordingly.

Reactions of
AVM and
Siemens to info.
One knows Nunja that such hearing actions are naturally forbidden, also without the press releases. Potential aggressors will not let themselves however well be deterred from it.
I find it good that AVM revises accordingly reacted and various things in the firmware. I would wish myself of all manufacturers. More importantly a revision of the DECT Standarts, which does not succeed probably by a manufacturer alone, is however probable. It would be good, if this “handshake” runs off in principle coded. The moreover discussions should be in principle coded. These dropbake on “unencrypted” is the largest deficiency, which should be absolutely eliminated in a DECT revision - also in the Repeater mode.
The answer of Siemens is really an evidence of incapacity.

Question:
Can one hear Gigaset of telephones with the published information?
Answer:
Requires detailed technical knowledge as well as additionally the appropriate hard and software, in order to hear DECT telephones. Hearing telephone calls in all other respects represents a criminal offence existence. It is not possible to hear telephone calls coincidentally. Beyond that also manufacturing and spreading from software are to the purpose of hearing DECT telephones a criminal offence. Hearing requires thus - apart from the published information also still the entrance to the technology as well as to forbidden software - also a substantial criminal energy.
|
In other words: It is technically possible to hear discussions but it is forbidden.
If it were technically not possible, it to point out not so in detail and repeated that it is forbidden, but simply to write that it is not possible.
Apparent they do not want to undertake anything, instead the customers for stupid are sold.
Hearing of telephone calls was already forbidden with the similar devices, that Siemens however not held positioning DECT as safe alternative.
Naja, the usual attitude: which is technically feasible (and not wanted), forbidden. And which is forbidden, cannot be.
I read somewhere that the maps, which are necessary for the PCs, in order to emulate a basis are in the meantime completely sold off. There probably some still fast covered themselves up.

And do you believe that Siemens has a fence, a lockable gate and a guard service, or only a large sign, on that stands for “entering for unauthorized forbidden”? Finally unauthorized entering would be a criminal offence, which would require criminal energy and therefore be cannot.
Nee, Siemens sells business-divides including guard service before it broke to go or still more badly - to improve have…
Hello,
I have times a question: I use a Gigaset S68H dirket attached to the FB 7270. In the DECT I observed monitor during the discussion that with coding “on” stands. Does this mean the fact that the DECT coding is activated and does not hear is possible? Or does this refer to another coding?
That is really the DECT Verschlssselung.
On the AVM Internet sides there is somewhere also a suitable description in addition. There however a “1” is represented instead of “on”.
Edit: On the AVM side
http://www.avm.de/de/News/artikel/DE...rzmeldung.html on the GIF picture click. The “1” is red encircled.
This hearing topic makes also large concerns for me.
After which one reads, and/or after which which in chaos radio to it was said and with dedected.org to be read is, I mean the following to have understood:
Generally
unencrypted predominantly very old devices and approving of models are in <30 euro the range. Unfortunately ses gives so far no reliable lists, to which devices applies.
Hear unencrypted telephone calls is easily possible, however (so far) only what is spoken at the mobile part and (so far) only by noting the data stream and following playing of non removable disk. Direct monitoring as with the radio does not go (so far).
Telephone calls also coded can be heard by a trick, if the aggressor creates it, the mobile part of the original basis on its “gefakte” basis (PC map) to return. In addition however the signal of the “Fake” would have to be stronger basis, than that the original basis, which the case might be only rare.
There is for the PC map so far no software for connecting with basis stations, the map can only with mobile parts connect itself.
Is however probably also only one question of the time.
According to chaos radio 4 man-years would be necessary, in order to program a complete minutes stack for the map.
I understand that in such a way: As long as the stack does not exist, nobody can telephone thereby over stranger basis stations.
There is thus still another “grace period”.
Do not telephone over strange basis goes with switched on coding, as long as the key are not cracked, and/or are not published key crack Tools.
By programming the pin (not equal 0000) becomes the coding somewhat more surely.
The PC maps are (almost) sells off and for years no more is not manufactured, the existing originates from the insolvency mass of the former manufacturer.
Is the question, how many maps are at all “in the market”. The map was a rather rarely sold niche product (Skype over Notebook)
We accept, it gave at that time 20,000 pieces. More than half lies probably already in the garbage, other one lies somewhere at uninterested customers unused in the drawer….
Only who received at all, to which the map (deviating from the original purpose) is good, it with Ebay will sell….
Thus I would estimate that less than 1..2 thousand maps for “hackers” are available.
I.e. statistically seen not even a map on 40.000 inhabitants, and/or 10,000 basis stations
The probability, which becomes hearing the people sport, is thus in my opinion (so far) very small.
Trotzdem ein ungutes Gefhl...
I think, it rather Detekteien and similar companies drauf will fall myself, because I see the possibility in such a way acting there to more toward restaurant economics and. And the stack to crack, will already succeed to those, only that will not become public surely.

What there would a proof for you be? I mean, one can easily in a report pretend one would have it get coded DECT discussions to hear and/or in basis stations in-lure themselves. So long you you not building guidance and left for the software publish, you that would probably hardly accept.

According to chaos radio DECT was introduced only a few years ago in the USA.
Here stands:
“That
DECT standard 1991 were sketched and discharged 1992 officially ".
It stood somewhere still that the first DECT equipment came 1993 on the market.
As the FBI could hear before 20 years DECT of telephones, which came only before 15 years on the market (and in the USA only very many later) ?
K
Reliably there is suitable hardware, the developers of the Phones must the Dinger also somehow test, only these measuring instruments and transmitters is very very expensive….
For PC's there is from Gigaset both a DECT USB stick (have I recently only again in the trade seen), and different Gigaset DATA adapter (USB, serial) it gave also times a PCMCI DECT map to the safe

Surfen over ISDN, when WLAN was not yet so common.
Reliably there are also still different manufacturers, that threw suitable modules as “Wireless” modem into the market. It is also not to be excluded that perhaps also to keep as small as possible (large) a part of the logic was managed by drivers on the PC by software and under use PC of the processor (around the costs/size of the Gertschaften and maximize the profit.
Thus I could imagine that interested developers of kind of rear wall could extend such HW gladly by own functions to want to spread (without panic).
Belonged however already some to it, binaries “read” and to understand - and superficially also still “improve”

One really needs notion of the subject (DECT minutes, prop. guessing acres extensions of the manufacturers, hardware understanding and Reverse - Engeneering experience).
In relation to this expenditure a very small use stands to probably realize times the neighbour to belauschen or to telephone in vain (with VoIP still more simply).
Which concerns the criminal energy - which presupposes usually possibly a potential monitren advantage, which justifies the risk and the expenditure.
Thus I do not make myself around my DECT of devices concerns. I do not trust my neighbours in the periphery of 10 km approximately the necessary know-how too, nor I subordinate an interest, my DECT to one of those to possibly tap.
All mock fights…

Also on youtube one finds videos, in which with appropriate Tools one demonstrates, as a WPA2-Netz becomes successfully “cracked”.
It recognizably “breed force” proceeded, with a sorted word list, in which the entries consist all only of 10 to 20 small letters.
Purely coincidentally

the correct WLAN key in the video begins then also still with a letter very far in front in the alphabet and consists really only of small letters, so that finding the key out takes only a few minutes.
Who regards as conclusive “proof” that WPA2 is generally “crackable” not to really help is.
Such videos show only, how important it is to use a “good key”.

Already. The critical at the WPA2 is however that the “attacked” does not receive the attack so easily. Someone, which sits in the catchment area of a WPA2-Verschlsselten WLANs can thus more or less unidentified over days or weeks of passwords try.
For that very reason the passport cliche is not to be so fast crackable also by dictionary (or by the unsatisfactory length). A clever password will not be able to crack also over weeks so fast - all the same whether with diagram map or traditionally.
That is here nevertheless however not the topic, because as said: Breed Force is no cracking in the actual sense, but blunt trying.

@ electrical: You believe to receive nich seriously here a guidance, to the best still for Klicki Bunti Windows!?

Ask nevertheless the people dies publish have.
Hello together,
thus I am the opinion that the topic is only largely aufgebauscht. Clearly one can hear many DECT devices. Only which brings it, if I buy specially a telephone, which now codes and which none dropbake on unencrypted communication makes? Nothing at all.
You also times remembered that coding does not bring purely nothing at all, if no END ton END coding is made.
The way is safe from the hand attachment to the basis station, but thereafter? Where please is the coding with Voip? Where becomes with the similar to and/or. ISDN line codes? In 99,9% of the telephone calls not at all.
There is SRTP, only offers nearly no VoIP Provider. In addition it comes that both interlocutors must support SRTP, since otherwise also dropbake one makes. And the universal remedy is that also not. Because this concerns no coding, which is based on asyncronen keys.
Or one takes this ominse Skype. Completely madly, there minutes are used, which are coded and where only Skype can decode.
That imagine I each mark, if I make Telefonbanking. The discussion runs unencrypted over Internet. With the Onlinebanking walk everyone that one is to make sure that the connection is SSL secured. With the Telefonbanking the whole is still worse. There account number and pin are enough, in order to accomplish transactions. With the Onlinebanking one has few still iTAN and something similar, speaks somewhat unique.
And if I do not even use Voip, in order to call with my bank, but fixed net, is not coded also here. Also here can be heard problem-free.
Thus all again not further as Medienhascherei.
If I want to hear someone, over Voip telephones, then I must leave and me completely comfortable before the dwelling of the Opers place ideally not times my dwelling, but make from the domestic living room. Or there iim case of fixed net installation which beautiful into the switching boxes, which there without break-down signalling system at the roadside.
There can be more security only if each uses telephones, as it the heads of state to begin.
With asyncroner coding and mark, which are based on a PKI.
That is again the same topic as the discussion around open WLANs. If I want to surfen really anonymous, then drive I into the next larger city and set me into the next Internet cafe. The Web meeting pay I bar. And thus me also guaranteed nobody on the monitoring video of the cafe recognizes, before do not disguise not forgotten.
That is also not at all desired. Like is otherwise
Schuble & cost. with suspicion telephones to tap can, without
to have to penetrate into the dwelling?
All Provider is committed to interfaces by law, for one
Monitoring to make available (inclusive. Externally stored data storage…)
One do not END-ton-end coding at all is in the public interest, in many
Coding is even forbidden to countries (e.g. France).

There you are right.
But it concerns the proportionateness.
Before you can hear a cable, you must come to the cable, i.e. is necessary physical accesses.
The whole we fast discovered, is time-consuming and probably expensive.
In order one transmit-strains to hear, can one in the corner place itself simply somewhere.
The devices are gotten cheaply too, physical accesses are not necessary, are thus also not so fast discovered.
Ergo: In any case only coded hand attachments take, also, if the remainder of the distance is unencrypted.
The whole is now times only as “safe” as the weakest member, and which is transmit-strains.
There I must unfortunately contradict you. The schwhste member
are the ignorance and Unbekmmertheit (my DECT or
my GSM telephone codes, therefore am I).
You may be right that the danger potential with DECT
in direct proximity (up to 400 meters) by the radio transmission
a weak point represents.
That is however the smallest problem. We have a deregulierten market,
the Telekom is not any more with the state monopoly on communication
to equate. Discussions go uncontrolled both over fixed net
Lines, and over IP distances, transmitting straining, sowing elite
Connections etc. without a participant has dedicated options.
In addition it comes that many services by outsourcing partner
, complete control and security are furnished hardly are
possible.
The scandal with the Telekom - service center, the account data of
Customers sold are not at all so long ago, hearing scandals in
Enterprises such as Telekom and Bahn make the round, Nokia
law intersperses for coworker monitoring in the homeland,
the policy would like further authorizations to the surface covering
Monitoring of communication implement. Nobody has really
an interest in the keeping of the Privatsphre of the citizens and on
safe communication (except the citizens themselves).
That this Ignoranz naturally also door and gate for non-governmental
Organizations/criminal opens, in purchase one takes
(we have laws gagegen, and which bad boys get
we with the surface covering monitoring and externally stored data storage…)
Correctly, complete security does not give it anyway.
But therefore to say, it is no matter, whether one uses coding or not coding DECT equipment, finds I nevertheless very daring and counter productive.
I believe, it was in this Second Channel of German Television frontal transmission, where a Apothekerin was abeghrt.
This deals with personal data, which should not arrive outward.
Naturally she can be heard just as well on the remainder of the distance, but by far not so simply and purposefully.
To hear one can do everyone in various way (Babyphone
Function integrated by Handy's/Dect devices, Notebooks with
Microphone/loudspeaker, which one taps over suitable SW,
Arranging microphones, mini transmitter, a small induction coil + amplifiers
in the proximity of the voice grade channel with similar telephones…)
That one also created it now straight times with DECT (which
allegedly coded) provide for a few waves, because one otherwise
no message has. The danger potential more coded by not
DECT communication in relation to the other methods is not
much more largely. One can always unauthorized into the Privatsphre of others
penetrate, owing to modern technology also from safe distance.

Around a special person, i.e. in this case, to be able one hears, must special DECT equipment only once find out, one which basis (RFPI) “taps” must.
With the DECT Sniffer one can synchronize also in each case on an individual basis.
In a normal populated area one sees several dozen of basis stations (RFPIs) however fast.
Hello together,
thus I must say, somehow contradict her nevertheless you.
On the side speak you of proportionateness and expenditure, on which other side oh like importantly that it it is that DECT codes also.
That is nevertheless a contradiction.
Who has please interest to hear a small Privatmann. Also here one can bring the argument that the expenditure/proportionateness stands in no relation to the Ertag. Speak which is thereby rauskommen if someone hears me.
Also in the contribution it is grumbled that the manufacturers play the danger down. But you speak of proportionateness. And nothing else is what the manufacturers also say.
Are we nevertheless times honest, who hears? That is on the one hand the state, and on the other hand enterprise (industrial espionage). Enterprises want firm secrets, and gibt's not with the small man. And the state does not want also nothing, so long one a potential danger for the state and/or. public security represents. Also that is not with 99% the Federal citizen the case.
Thus if one is already heard fear before has, then one must protect oneself against state and companies. And there one does not need to come with the ridiculous DECT coding.
And always Dramatisiererei in such contributions. Oh God as bad, one hears vertrauchliche discussions in the pharmacy. Who please wants to know, what the pharmacist discusses with the customers? Perhaps an insurance, the employer or the health insurance company interests. Do you mean, now park in their order before each pharmacy in completely Germany during the opening times a monitoring car, in hope, their own customer/coworker call coincidentally straight in this pharmacy?
And which comes next week into frontal? It is shown there that one can hineinhorchen with arranging microphones into a dwelling. And which then? Then the bricklayers are accused of, they were not bricked the walls.
Or Babyphone: Completely does Germany use no more Babyphone?
Otherwise I know cando only an agreeing. Today the own data run nevertheless over ways, which cannot forecasts.
Still coded DECT is considered as “reliably”. At least it cannot be heard by everyone petrol-normally with Com on air map and Linux.
I find the announcement also the coding irreverent to go around to want and so the DECT standard destroy. In hospitals every few meters DECT Basen e.g. hang on the wall rum, over which confidential data go and also are used, because to a physician over fixed net can be achieved, because one white where he is not can life-saving minutes apply. With a program that it would make possible for everyone to hear coded DECT it would have to be reequipped the entire DECT Technick on/, which brings immense costs with itself. One should nevertheless roll not let such “programming, Crackern, hackers etc.”, before all with the foreseeable consequences. Surely it will crack sometime someone, the coding, but up to then, does not have one not still specially on the fact to work that this time x moves still faster closer. Foreseen that there are so long no programs, which go around a coding also no abusing evenly such give can, e.g. from terrorist (the argument nevertheless always pulls

) Thus Schuble: Put to the DECT hackers the handicraft.
Security by Ignoranz? I think times, it am very important to point the borders out so that products are improved. As long as publicly safety gaps are pointed out, the risks can be estimated at all by the customer.
The hackers, who point the gaps out, are the good ones, the bad ones use the gaps secretly and have also no interest that this admits at all becomes (there they would lose the advantage by the gaps).
Therefore a pursuit of “hackers” is etc. meaningfully only if these abuse their knowledge for crimes. If they publish your realizations, they help to recognize the gaps and close. That is the best means around an abuse to prevent to make more difficult (and the bad young the life).

It speaks against it nothing, if “the good ones” point weak points out.
If they make the bad one available” of break-down tools however by Internet “, the difference between property and bad blurs for me…
My entry door has still another simple cylinder lock.
I would find it, if not at all merry at Passanten distribute appointed policemen duplicate keys for my entry door, in order to make attentive publicly on safety problems of my door lock.
There I would already ask myself whether the “property goods” are not in reality employees of a door lock manufacturer, that exerts gentle pressure on its potential customers…
Knuffi thanks! Exactly THAT was my background thought to it, only that you created it it more plausibly to explain.
In my opinion there are enough nevertheless, if the “good ones” do not communicate, which are present such safety holes, but custom one to the public espionage software publish, which is published nevertheless only in addition so that the “bad ones” also use it. Or does someone know a legal reason to load itself such software from the net?
A goal was not finding an espionage software, but decoding DECT, in order to be able to provide an open SOURCE stack. One is evenly pushed over this safety leakage. By publication of the software it is only possible to examine different DECT devices for security. A loose “DECT is” gets out nevertheless nobody uncertainly hinter'm furnace. Only if a gap is really proven, a public discussion is activated.
Otherwise to publishing safety gaps:
http://www.it-academy.cc/article/120...isclosure.html
In order to remain times with the example of the door lock. We accept, someone have the same door lock as you and state with an attempt that one does not need key. Actually a screwdriver and something Kraft are enough to up-close over. He could keep this knowledge now for itself and tacitly exchange its own lock, in order to be even safe. Or it could inform first times the manufacturer and go with Nichtreaktion to the press, in order to move as much as possible for the change of the obviously uncertain locks.

That is nevertheless times very suitably a selected user name.
As long as you do not know anything from a danger, there are not those also. Also sometimes “head into the sand to put” one calls.
You assume that thus that after there is already DECT for many years that, which published it also first are, which found it out? It is many more probable that already different others found it out and not to have published. And you did not experience anything of it, you so long felt safe.
@Knuffi
Which concerns the comparison with the lock, then a lap, which one can open only with duplicate key, would be safe. It, even if one can open it without duplicate keys, is uncertain and/or. if one can manufacture oneself this duplicate key, without needing for it the genuine key.
And which concerns the “security” of your lock, if you really believe that your lock is safe, have you already times your key forgotten/lost and called a fitter, so that that opens the door? That gets the door faster up, out you to look can. And want you serious to state that something that admits to each fitter is admits not also in criminal circles becomes?
I think the publication of the safety gap was a correct decision. Really on the one hand also pressure can be made attentive on the industry is only in such a way exercised to develop further and make the standard DECT again safe on the safety risk and on the other hand.
Are exactly the same opinion of mightyEx. Would e.g. be. incoming inspection the Hacking in the Internet and media not so popular become, we would surfen probably still all with incoming inspection coding and us also still safe thereby would feel.

The way was published, like the topic, i.e. in form of reisserischer reports in boulevard television magazines without sober estimate of the real “threat situation”, is more than doubtful in my eyes.
The appearance (better would be still another genuine live-demonstration) on the congress of CCC was treated quite briefly and a technically correct contribution in c't, where the topic unaufgeregt pleasing essentially and, but, would have perfectly been enough.
If one does not have, but with the Veffentlichung exists the chance DECT better to understand perhaps to call and an open SOURCE DECT project in the life, those the prop. guessing eras, perhaps outdated mechanisms around modern Cryptographie solutions supplements and into a new open standard for SOHO radio telephones with small transmitting power comes up.

And where do I get for the moment a “absolutely safe lock” (DECT)?
There are none and probably more than 1 year will take, until there which are.
In the meantime do not only become
very few “inaugurated” criminal ones, but each Kleinganove the trick and the associated tool found.
Quasi one more than 1000 subject multiplication of the potential burglars.
And which is with the many “notionless” owners of telephone, who the problem not received and/or understood?
What is with those, which do not have the money to buy in the 3 Jahrerhytmus a new “safe” telephone?
One likewise proved a substantial “disservice” to those with the publication of the “break-down tools”.

History with the DECT coding/not coding is nevertheless for a long time well-known. Siemens has starting from the then new 2000er/3000er generation explicitly with the coded transmission and safe telephoning over DECT recruited…
Which meant implicitly for each customer to finally transfer to the new DECT generation because the old devices did not code and were uncertain…
The same will still again pass, it will become new generations will come, which are better. With the Gigaset series came also a technology jump, which was no longer downward compatible.
Also with DECT will happen sometime. (like straight with the similar radio telephones, which were pulled by law for this year from traffic).
There are meanwhile VoIP of mobile parts/Smart Phones, which send over WLAN and so that incoming inspections/WPA have as coding. Those are not as radiation-poor only stop as DECT. Who wants to have it now already more surely, could jump up on this course.
Also the general opinion holds itself that in the GSM net codes mobile telephones surely and transferred (Frequenzhopping…) Also those can by the way be heard with technical means…
By the way, (nich certified) broadband - one gets scanners in many import/export shops in each larger city center to buy, which one possesses, but in D not to use may. With those one can aeronautical radio, police radio, operating radio and otherwise still which monitor… As a radio amateur professional Equpment is available (one can purchase also on-line) and with the arithmetic performance of today's PC's one can make thereby also many more, than petrol-normally a citizen introduce oneself can.

Incoming inspection is a completely bad example of security. That is cracked into minute-fast - with HW of the bar.
WLAN Phones are up-to-date no real alternative, but for other reasons:
- smaller range
- higher current consumption
- no own frequency range (conflicts with Bluetooth, microwave, AV-transmission-systems)
- Administration expenditure (IP address, coding, SSID, Kanalwahl)
Therefore I mentioned also incoming inspection, it am stop not much better/more badly than DECT…
And as it and that was cracked the round made, gave it the necessary “innovation pressure” for WPA/WPA2…
In addition, during the many Hot Spots and the large spreading of WLAN in the households, as well as the introduction of VoIP is quasi available/common as basis for new “localbound” radio telephones (despite Microwellen, AV of systems and blue tooth)
jesas which gives is that for a statement, then it probably no industrial espionage geschweige to the pirat copies it is prohibitions and thus there is not that.

It has of course times heard of it that the telephones can be heard, stirs up however off: “If one in the real life introduces oneself, would have then a criminal person - hearing telephone call discussions is a criminal action - with a monitoring delivery van directly before its entry door to place, or, if they have a flat, itself this criminal person would have some days into the neighbour dwelling before in-rents”.

Who attaches importance on security, must also constantly invest in it, because which today is still safe, is tomorrow perhaps already outdated. That applies to all safety devices, technical systems and organizational precautions.
About industrial espionage: 90% the successful Atacken are implemented by Insidern in the companies (frustrated coworkers etc.) and are very difficult to prevent.
Most know-how flows off over Abwerbung of the knowledge carriers from the companies. In addition come the many advisor companies, which give themselves the handle to the hand and naturally with the know-how also “fertilize different”. The management more know-how profit than damage obviously promises itself by know-how loss of the advisors.
Which concerns the pirat copies/patent injuries: who its production into countries without copyright protection like e.g. China pages out, is even debt. That plagiarisms from cheap wage countries on the market come are also because of the “Premium” price strategy of some alleged luxury companies. The larger the difference between value of a product and demanded price are, all the more attractively are a falsification.
The DECT problem is there rather infinitesimal in the statistics.
But even a weak coding is better than none. Around the example W-Lan times on to seize prevents an incoming inspection coding direct access to the respective net without supplementary product lines. And attacks only by the fact it prohibitions is “to denials” hold I for too simple.
A little verschlseln nevertheless the DECT devices does for approx. 1998.
