Moin!

Irgendeine Organisation mit viel Geld und technischer Kompetenz hat
das Osloer Regierungsviertel mit IMSI Catchern zugebaut (1)(2).
Messtechnisch aufgespuehrt haben die Reporter des Aftenposten die
Geraete mit einem GSMK Cryptophone (3). Das prueft drei Eigenschaften
von Handymasten, die auf IMSI Catchern hindeuten, und zeigt sie an:

"The first notes when a phone shifts from a more-secure 3G network to
a less-secure 2G one. The second detects when a phone connection
strips away encryption, making interception easier. And the third
reports when a cell tower fails to make available a list of other cell
towers in the area; this is called a “neighbor’s list,” and it allows
phones to easily switch between nearby towers. IMSI catchers typically
don’t offer lists of alternatives because they seek to keep phones
captured." (4)

Damit wurden ebenfalls viele IMSI Catcher in Washington DC gefunden.

Viele Gruesse und /stay wiretapped/
