Spying goes beyond the criminal snooping it’s often reduced to. For law enforcement, it can be the only way to convict criminals when they fail to cooperate with police, allowing them to uncover new evidence about a crime away from the interrogation room.
National security agencies can use it to enhance public safety by enabling investigators to gather intelligence on potential threats, foreign espionage, and international crime.
One of the most common techniques for legal, ethical spying is technical surveillance, which allows entities to uncover information that is being deliberately hidden by their targets so they can take appropriate action against them.
This article tells you everything you need to know about technical surveillance, including what it is, how it’s conducted, and when it’s appropriate to use for intelligence purposes.
What is Technical Surveillance?
Technical surveillance is the use of electronic devices to spy on people or places. This can involve listening to conversations using hidden microphones, recording videos using hidden cameras, or tracking someone’s movements using GPS trackers to uncover information.
These devices can be very small and cleverly disguised, making them difficult to detect. This makes it possible for investigators to record conversations and or video footage of their target without their knowledge.
Law enforcement and intelligence agencies can also track a cell phone’s location using cell phone towers or GPS as part of their technical surveillance initiatives. Software can also be installed on a computer to monitor keystrokes, websites visited, and other activity.
How is Technical surveillance conducted?
Technical surveillance is primarily focused on discreetly gathering information through technology. The two main approaches are the installation of hidden devices and the exploitation of existing technologies.
Here’s a breakdown of the most common techniques:
1. Hidden Devices
In technical surveillance, tiny cameras and microphones can be disguised as everyday objects, such as buttons, pens, or even power adapters, to secretly capture live audio and video. Investigators can then retrieve the objects when the target leaves the location and use the recordings as evidence against them.
2. Signal Monitoring
Signal monitoring focuses on detecting and analyzing electronic signals from communication devices rather than using physical devices like hidden cameras. This could mean monitoring radio frequencies used for communication from things like walkie-talkies and wireless cameras, using specific radar signals used by certain vehicles (military, law enforcement), or even tracking faint non-linear emissions from listening devices themselves.
3. Network Infiltration
In technical surveillance, network infiltration refers to legally gaining unauthorised access to a computer network to gather information and steal data from the target’s devices.
Once investigators gain access to the target’s network, spying software like trojan horses or keyloggers can be installed on target systems through various means, such as phishing emails, malicious website downloads, or physical access to a device. Once installed, this malware can steal data, monitor keystrokes, capture screenshots, or even activate hidden cameras/microphones.
Investigators can also intercept network traffic by Intercepting and analyzing data flowing through a network, revealing information about the target’s communications and activity.
4. Tracking Devices
Tracking devices, such as GPS and cell phone trackers, are vital tools in technical surveillance for monitoring a person’s location and movements.
GPS trackers can pinpoint a target’s location with varying degrees of accuracy and are often covert, often magnetically attached to vehicles, or hidden within belongings.
Once active, they transmit location data via cellular networks or satellite to a monitoring platform accessible by the party conducting the surveillance.
With legal authorisation, law enforcement or intelligence agencies can also track the location of a target’s cell phone through cell towers or GPS. This provides a general idea of the phone’s location based on the nearest cell tower or the phone’s GPS coordinates.
Can technical surveillance be prevented?
It’s very difficult to completely prevent technical surveillance, especially when sophisticated adversaries with significant resources use it. However, individuals and corporations can take steps to increase their chances of detecting it if they have concerns that a third party, unrelated to government and law enforcement agents, is illegally using technical surveillance to gain confidential information that may be sought by a competitor or for insider information for investment or other illegitimate reason.
For high-risk scenarios, employing professional Technical Surveillance Countermeasures (TSCM) specialists like SIP International is the most effective way to prevent unlawful technical surveillance on your business.
Certified TSCM specialists can conduct sweeps to detect and neutralise hidden surveillance devices such as RF bugs, hidden cameras, GPS trackers, and other electronic spying tools, using specialised equipment and techniques to sweep buildings, offices, and vehicles to detect hidden devices.
Businesses can also educate employees about social engineering tactics and best practices for cybersecurity hygiene to reduce the risk of malware infection or accidentally granting access to unauthorised individuals looking to spy or steal confidential information.
When is technical surveillance necessary?
Technical surveillance can be a controversial topic. While it may sometimes be intrusive, there are many reasons why someone might use technical surveillance, including tracking criminal activity, conducting national security investigations, and, in some cases, for corporate espionage.
1. For Law enforcement
In cases of major crimes like terrorism, kidnapping, or drug trafficking, technical surveillance can be a crucial tool for gathering evidence, tracking suspects, and protecting the public from dangerous criminals. When someone goes missing, especially under suspicious circumstances, historical tracking and monitoring devices or cell phone location data can also be vital for locating them quickly and ensuring their safety. In either case, subject to the nature of the technical surveillance intended, a court order is often required for surveillance to be used legally.
2. For national security and intelligence
Intelligence agencies use surveillance to monitor potential threats, gather information about terrorist plots, and disrupt attacks before they occur. This involves monitoring communications, tracking individuals suspected of involvement in extremist groups, or using facial recognition technology to identify potential threats at airports or other critical infrastructure.
Surveillance is crucial for detecting and preventing foreign espionage activities that threaten national security. This could mean monitoring the activities of foreign diplomats suspected of spying, intercepting communications between foreign intelligence agencies, or using technical means to uncover attempts to steal classified information.
3. To prevent workplace theft
Another critical use of technical surveillance is to prevent workplace theft. Large Companies often use surveillance cameras to deter property theft and monitoring software to prevent employees from stealing confidential information or leaking trade secrets.
In the event of ransomware or a data breach on a corporation, technical surveillance techniques like network infiltration can be pivotal to finding the source of the attack, preventing further damage to the business and safeguarding corporate data.
4. To detect insurance fraud
In personal injury claims, insurers might use hidden cameras or GPS trackers to monitor a claimant’s activities. For instance, if someone claims to be too injured to work but is seen engaging in physical activities on camera, this can be used as evidence against them to deny their insurance claim.
For staged car accidents, insurers can use traffic cameras or dashcam footage from surrounding vehicles to analyse the sequence of events and identify inconsistencies that might suggest a deliberate collision. This can help reconstruct the event and expose inconsistencies in the claimant’s story about the accident.
The use of technical surveillance in insurance fraud investigations must comply with privacy laws and regulations, and investigators often need warrants or authorisation before deploying many of these surveillance techniques.
