UAB "Darseta" is a defense & law enforcement technology provider
for Government Intelligence and counterintelligence agencies.
Deployment of hostile base stations (IMSI Catcher) has become a common threat as costs and procurement hurdles have been continuously falling. The GSMK Overwatch network security system is the world’s first system capable of distributed detection, localization, alarming and neutralization of active attacks on mobile communications via the air interface. The system integrates and synthesizes data from sensors in a national situation report for cellular communications, allowing network operators, government agencies and information critical industries for the first time to detect and combat rogue base stations used for eavesdropping and fraudulent activities in real time.
1. IMSI Catcher
IMSI Catcher – is a telephone eavesdropping device used for intercepting mobile phone traffic and tracking location data of mobile phone users. Essentially a “fake” mobile tower acting between the target mobile phone and the service provider’s real towers, it is considered a man-in-the-middle attack.
DIMSI Catcher are deployed by governments and criminal organizations. Typical IMSI catchers targets are government, military and businessman phones and communications.
2. GSM blockers.
Placed in strategical terrain can block government and military mobile communication.
3. GPS blockers.
Placed in strategical terrain can block the sensitive military equipment or aiport and seaport navigation.
4. GPS spoofers (incorect GPS signal transmitter).
Placed in strategical terrain can mislead military equipment or aiport and seaport navigation and cause airplane catastrophe or ships navigation problems.
In strategical terrains (President palace, Parlament, Ministries, Ambassyes, Military buildings, Military bases, Airports, seaports, etc.) are deployed stationary GSMK OverWatch sensors and military-grade mobile sensor system for on-demand monitoring of temporary hotspots are deployed near hotels with political delegations, near temporar military and etc.
GSMK OverWatch Manager is deployed in intelligence or counterintelligence buildings.
All data collected by stationary and mobile sensors are send to GSMK OverWatch manager, analyzed and all threats are detected immediately.
1. Precise 24/7/365 counterintelligence information about working IMSI catchers, GSM blockers, GPS blockers and GPS spoofers in strategical terrain.
2. Arrest of illegal users of IMSI catchers, GSM blockers, GPS blockers and GPS spoofers.
3. Illegal use of IMSI catchers, GSM blockers, GPS blockers and GPS spoofers becomes impossible (does not interfere legal IMSI Catchers).
GSMK OverWatch system is installed in Berlin, Germany (Berlin – Mite district). It is test-demo version.
