Text: Interception Overview
Forewarned is forearmed
Interception of communications has become the most crucial task in intelligence and surveillance. Reliable,
portable, robust solutions are critical to the success of any operation.
That is why ABILITY has created industry leading integrated solutions to cover the many facets of
Ability provides industry leading solutions for many types of needs, with off the shelf and customized systems
that have been field proven around the globe.
On the cellular side, we can provide turnkey integrated solutions that cover all GSM and CDMA networks,
providing real time offair interception, robust, ultraportable design and userfriendly operation.
On the satellite side, ABILITY can provide fieldproven, cuttingedge solutions for IRIDIUM and Thuraya as well
as for various global and regional satellite communication operators (“Intelsat”, “Eutelsat”, “Arabsat”, “Domsat”,
“Indosat”, etc.) including VSAT and DCME.
Ability has developed advanced systems to cover satellite interception for major mobile satellite communication
systems: Iridium and Thuraya .
The systems can be installed on various platforms, such as vehicles, vans, shelters, fixed installations, ships,
They can be used either as portable standalone tactical systems or as frontends integrated with larger scale
In addition, Ability has developed SLIS – Satellite Link Interception System for interception of global and
regional satellite communication operators (“Intelsat”, “Eutelsat”, “Arabsat”, “Domsat”, “Indosat”, etc.) including
VSAT and DCME.
Our fully passive cellular interception solutions are based on state of the art technology and extensive field
experience. Active GSM interception systems and IMSI/IMEI catchers are also available.We currently
offer five types of solutions:Passive GSM Interceptor GTReS – GSM Traffic Recording SystemActive

Passive GSM Interceptor
GTReS – GSM Traffic Recording System
GTReS is a multiband fully passive GSM interception system designed to record the entire traffic occurring
between Base Transmitting Stations (BTS) and Mobile Stations (MS) located within the system’s operational
range. This means literally tens or even hundreds of simultaneous calls.
“Fully passive” means that:
GTReS does not have any transmitting parts;
GTReS does not interfere with GSM networks and mobile phones;
GTReS’ operation is completely undetectable.
Recorded information can be processed either online or offline.
GTReS can intercept:
Primary and secondary DTMF tones;
Call related information
The system supports both types of encryption implemented in GSM networks – A5/1 and A5/2.
A5/2 realtime decipher is a software based solution; it works as a background application. Average
deciphering time is 15 msec.
A5/1 decipher is a separate device connected directly or remotely to the GTReS. For more information about
A5/1 deciphering, please refer to the RTDM51 description.
Active GSM Interceptor
IBIS II - In-Between Interception System - 2nd Generation
The IBIS–II is the most advanced and newest GSM interception system in the market. The system was designed
and developed according to the vast experience gathered in the last 10 years, while deploying worldwide
hundreds of GSM interception systems, listening to customer’s feedback and analyzing customer’s operational
requirements. The IBISII is an advanced integrated active solution that includes all relevant subsystems in a
single unit, allows the user to scan, analyze, intercept, monitor, recordand track GSM mobiles, regardless if they
are encrypted by A5.1 or A5.2 encryption (monitoring is not done by forcing the mobile to use A5.0 or A5.2 but
rather by anintegrated deciphering capability).The IBIS–II is a standalone solution for off the air interrogation /
interception / monitoring / deception of tactical GSM communication, in a seamless way, without any cooperation
with the network provider. The IBISII is restricted for Law Enforcement Agencies and Authorized Governmental
Agencies and it offers them a powerful tool to intercept and track GSM communication of all types.
The IBISII extracts easily and in short time the mobiles ID’s such as IMEI, IMSI & TMSI and allows the user in no
time to identify his target mobiles and to monitor them. The IBISII offers a complete set of capabilities and
advance features to allow the user to control the GSM environment and GSM communication. The user can
control the level of service to the target mobiles, selectively Jam specific mobiles, perform silent calls, call or SMS
on behalf of target mobile, change SMS messages ”on the fly”, detect change of SIM card or change of handset,
and support Direction Finding system and many additional operational features.
The IBIS-II main capabilities:
All GSM in One Single Unit the IBISII includes all required modules for dual band
simultaneous interception in A5.2 and A5.1 environment. No need for any additional hardware.
Instant Set Up Timewithout need for external modules, setup is within few minutes only.
Dual Band Solution any of the required frequencies 850, 900, 1800, 1900MHz.
Real Time Interception for voice and SMS, Incoming and Outgoing, in A5/1 and A5/2
Semi PassiveInvisible & undetectable operation, no need for cooperation with network
Data Extractingsystem detects mobile identities including IMSI, IMEI, TMSI, MSISDN
(phone number), Kc etc.
Presence verification user can detect presence of specific target mobile.
Concurrent Callssystem Intercepts up to 6 concurrent duplex calls by default.
Selective jamming of communicationuser can block communication of GSM phones
defined as targets or specific network service (voice, SMS).
Direction Finding Supportby using silent call, target mobile is activated and can be
traced by external DF / Homing system.
Manipulation user can make fake calls and send fake SMS to / from target.
Remote Control IBISII can be operated locally by the system laptop, by LAN connection
and remote laptop or via WiFi, by a remote laptop.
System can operate with variety of power sources such as AC supply, batteries, car
supply etc and by that, it can be installed and operated in many types of applications
and environments (fixed installation, remote control configuration, transportable,
vehicular, man pack).
IICat – IMSI/IMEI catcher
IICat is a modular system that detects the identities of GSM phones within its operational range.
Thanks to unique sophisticated algorithms implemented in the system, the IICat uses relatively low power (usually
less than 1W) to attract mobile phones and force them to introduce themselves.
It makes the system very lightweight, portable, virtually undetectable and highly efficient with mobile phones
located very close to the BTS.
Another great advantage of IICat is that the system can be easily upgraded to a full GSM Interception System
Smallest & Smartest 3G IMSI/IMEI/TMSI Catcher
← Automatically scans and detects parameters of all 3G networks
← Detects all 3G phones and collect all their identities (IMSI, IMEI and TMSI)
← Displays phone model, country of origin and name of network provider
← Measures distance to all 3G phones with accuracy of less than 30 m
← Selectively force only target’s phones to migrate to GSM mode. Rest of the phones stays in 3Gmode. Being
pushed into GSM mode, 3G phones stay there until reboot. It makes possible interception of such
phones by GSM passive interception systems. Active systems, after finishing interception, can send
them back to 3Gmode.
← Selectively blocks communication of 3G target’s phones.
3GCat can be used either as a standalone device or integrated with Ability’s IBIS or GTReS systems . It can
also be integrated with GSM interception systems of other vendors.
