Meanwhile believes Anundsen that the findings from Aftenposten investigations can be “ordinary base stations for a period has been revised strength.”
The information appears in a new letter to parliament this week, where Anundsen answer several questions about false base stations from the Justice Committee.
ANUNDSEN statements arrive while the investigation is still ongoing and without Police Security Service (PST) has talked with several key sources who assisted Aftenposten mapping mobile monitoring equipment in Oslo.
Did own findings
Before Christmas last year revealed Aftenposten signals from it most probably was active false base stations, so called IMSI catchere , several locations in downtown Oslo.
Just hours before the case was published on December 12 completed the National Security Agency, with technical assistance from PST, new own investigations, which concluded that it was made “findings”.
Three days later decided PST and Oslo police that it was “reasonable cause” to start investigation.
PST: – The Norwegian people can not talk about secrets on open line
When: Rejected Norwegian authorities
The time Anundsen that it “appears as unthinkable” that this could result false base stations that Norwegian authorities are using.
– I think you should look long in law after a legal basis for this type of business, said Anundsen Aftenposten.
Now: – Norway may use such equipment
In the letter to Standing Committee on Justice responds FRP -statsråden so the question of the justice committee if he could “guarantee that the false base stations / IMSI-catch forwards Aftenposten has revealed no equipment from Norwegian authorities?”
“Norwegian authorities can use this type of equipment,” and refers to the Criminal Procedure Act sections 216a, 216b and 222d and Police Act § 17d (see fact box).
Anundsen also emphasizes that there must be order by a court or by decision of prosecutors with the court’s subsequent control.
“In addition, the method in some necessity situations,” he adds.
– Ever legally equipment may translate
According to the minister may Aftenposten findings due entirely legal base stations.
“One must also take into consideration that quite legally equipment, such as ordinary base stations for a period has been revised strength, can affect who they Aftenposten have found,” he writes.
Anundsen would not comment on the letter or answer questions about the case.
From sources familiar investigation gets Aftenposten reported that PST believes the explanation on the newspaper’s findings are variations in signal strength in the mobile network and use of signal amplifiers.
This statement is rejected outright from those measurements performed in Oslo.
Rejects that they have concluded
PST has not tried or used the same type of equipment used Aftenposten but has established that they have access to “better equipment” – without that they will comment on what this is.
Trond Hugubakken, Director of Communications PST, do not want to answer Aftenposten questions.
– The investigation is still ongoing, so PST has not drawn any conclusions yet, he says.
Responds to report
Aftenposten 25,000 measurements before Christmas was performed with counterintelligence equipment used in a number of countries to unveil mobile espionage.
Kyrre Slettsjøe, general manager security company Cepia Technologies, who was with Aftenposten surveys, was summoned for questioning by PST Christmas Eve.
When he expressed a desire to have with him a lawyer, he was told that he could be arrested.
– It became clear to me early in the questioning that his main interest was to find any fault with the measurements, not to find those behind the monitoring, says Slettsjøe, who has extensive experience from the Norwegian intelligence service.
– I can hardly imagine that they could manage to find some watchers, who came so late in getting started with their own investigations, he said.
False base stations can be turned off in an instant, and then they are practically impossible to find. Aftenposten has previously written, disappeared signals after the newspaper wrote about the case before Christmas.
– We have long pointed high intelligence threat against Norway
– requires ability to read the manipulation
Security experts who have assisted Aftenposten, pointing out that for revealing mobile monitoring is crucial to analyze the protocols that are sent out to lure mobile phones.
The infrastructure of the GSM network sends instructions to mobile phones connected to the mains via protocols. False base stations attracts mobile phones by “manipulating” these signals.
– Detection of false base stations requires the ability to “read” this manipulation, not for measuring signal strengths and variety of these in itself. This seemed unknown to PST, believes Slettsjø.
Before Christmas let Anundsen forward a proposal allowing for a very powerful extension of PST and police authority to use fake base stations.
The proposal has faced harsh criticism from a number of consultative bodies.
PST met up unannounced in Aftenposten premises
Shortly after Anders Anundsen (FRP) had explained about mobile surveillance case in Parliament, appeared PST investigator in Aftenposten premises in Akersgata.
Aftenposten dispensed large quantities of raw data underlying the investigations into PST. Security companies that the newspaper had used as sources in cases were called for several long interviews right before Christmas.
In addition emerged two investigators from PST and Oslo police up unannounced in Aftenposten premises and asked to meet a of journalists in the case of a “conversation” immediately.
PST also asked to be given phone numbers and IMSI numbers Aftenposten had used in the case, which the newspaper did not comply.
