Aftenposten published on Wednesday all the raw data of their measurements of false base stations in central Oslo.

Aftenposten put in goes out the technical file have been used in the revelation that the false base stations, or so-called IMSI-catcher, in central Oslo on the newspaper’s website.

The magazine’s editor in chief Eskil Egil Hansen says in a statement that the purpose is to give the public an insight into how the newspaper proceeded.

The conclusion of the work presented in several articles from December 12 last year is that it most likely occurred interception of mobiles that existed in the area around the Storting, the Prime Minister’s Office, Ministry of Defense and Oslo financial centers over a period of October-December.

New measurements that the newspaper did 22 December shows that the false base stations now shut down.

Eskil Egil Hansen hope now that the newspaper’s publication of the extensive technical material to give the editors New clues which in turn can answer the question who or which actors were behind the interception. It is likely that equipment belonged to different players, according to Aftenposten.

The surveys also described in detail in a technical report.

This has been done is to measure and define the signals that are different from normal signals from base stations operators. This has been possible through the German mobile Crypto Phone 500 – working to reveal eavesdropping, and with the help of GPS data and constructed espionage equipment Falcon II.

Security experts from Aeger Group and CEPIA Technology has participated in the surveys.

Many of the discrepancies have been found in signal conditions have been natural, technical explanations after Aftenposten contacted including antenna researchers, police and operators.

But 122 results of 470 in the period October 10-November 21 is defined by Crypto Phone mobile phone as “very suspicious”.

The equipment that we used is described to be a demonstration edition of the Norwegian supplier Multisys.

The cell phone is a converted Samsung Galaxy whose software has been replaced with secure software that can analyze radio signals and manipulations of the cell phone. For example, it can check if the mobile encryption is turned off or if traffic is disconnected from the mobile networks, 3G and 4G and down to the 2G network. The latter suggests that the false base stations are in circulation.

Eskil Egil Hansen also believes that there are deficiencies in official work when it comes to reveal similar interception of Norwegian citizens, and calls the phenomenon “ansvarspulvrisering.”

Norwegian Justice Minister Anders Anundsen said yesterday in the Storting that a working group now be added between the authorities and he told me that Norwegian security police PST on tap sought for such base stations.
