The Right to Privacy in Thailand: Privacy International Submission to Human Rights Committee
5. IMSI catcher and other surveillance technologies
The technical surveillance capabilities of the Thai agencies are not officially
known. According to reports by Citizen Lab of the University of Toronto in
201319 and leaked communications in 201520, Thailand may be the current or
previous user of the advanced surveillance technology, Remote Control System
Galileo, marketed by the Italian firm Hacking Team. The Galileo system has the
ability to bypass encryption, take control of a user’s device, and to monitor
all activities conducted on the device, poses significant threats to the right to
privacy.21
More recently, government documents have revealed that Thailand purchased
IMSI (International Mobile Subscriber Identity) catchers. In January 2015, the
Swiss government released the list of export licences granted to companies
based in Switzerland that were selling surveillance technologies.22 The
document reveals that between March 2012 and January 2013, Thailand has
purchased nine items requiring an export licence under the category “Mobile
telecommunications interception or jamming equipment, and monitoring
equipment” and the subcategory “Interception equipment designed for the
extraction of voice or data, transmitted over the air interface”. This
is the
category of licence IMSI catchers require. Likewise, in the UK, since 2015, the
Department for Business, Innovation and Skills also started publishing data on
export licences. Thailand obtained six different licenses for telecommunications
interception equipment from the UK.23
IMSI catchers are devices that mimic the operation of a cell tower device in
order to entice a users’ mobile phone to surrender personally identifiable data
such as the SIM card number (IMSI). In recent years, IMSI catchers have
become far more sophisticated and can perform interception of voice, SMS
and data. They are also able to operate in a passive mode that is virtually
undetectable as it does not transmit any data. Further, IMSI catchers are
becoming increasingly cheap and these devices have been miniaturised to
the point of being concealable on a person in a crowd rather than requiring a
large van. But IMSI catchers are far from harmless given that their capacity to
interfere with right to privacy goes beyond the person targeted.24

Galileo is a remote control system which allows to take control of a target and to monitor them even if they
are using encryption. Hacking Team sells it as a tool to “bypass encryption, collect relevant data out of
any device, and keep monitoring your targets wherever they are, even outside your monitoring domain.” For

An IMSI catcher is portable equipment that allows the interception of data (phone communications, messages,
location data) from phones in its surrounding environment. Inorder for a mobile phone to function it has
to communicate with a cell tower. The phone then chooses the cell tower it communicates with based on the
strength of the signal. An IMSI catcher pretends to be a powerful cell tower - it sends a very strong signal
so that the phone in the surrounding areas connect to it instead of to an actual cell tower. Once connected
to the IMSI catcher some data becomes available to the person in control of the IMSI catcher. IMSI catchers
are often presented as a tool for targeted interception (one has to be geographically close to the targeted
person to intercept their communications), yet IMSI catchers can capture all the data of all phones in their
surrounding perimeter that connect to it. And indeed, some metadata from nearly every phone in the area
surrounding it. There is also no technical barrier for the operator to intercept many phone conversations
and SMS messages simultaneously. In general, each device can intercept eight phones in parallel but
additional hardware can be purchased to multiply this value to the desired rate.
