Due to high popularity of the post on SS7 hacking I am currently writing an update on this topic. Input is welcome. Here a short preview/summary:
Weaknesses in SS7 based mobile networks enable any user with basic computer skills
to perform attacks which can lead to direct financial loss, leakage of data and disruption of communication services.
Further I will reveal how to address issues in SS7 mobile phone hacking, which lead to location identification, disruption of calls, sms interception, Unstructured Supplementary Service Data (USSD) forgery requests (and transfer of funds as a result of this attack), call redirections, conversation tapping and disabling of a mobile switch.

This will NOT be a do-it-yourself guide to SS7 hacking, but rather a do-it-yourself guide on how to protect yourself.
