Cyber TSCM

Cyber Technical Surveillance Countermeasures


Cyber TSCM includes detection of eavesdropping threats and vulnerabilities within Wi-Fi, Bluetooth & Cellular networks. This includes the devices, the networks and the associated connections. Internet of Things (IoT) devices are included within the Cyber TSCM umbrella.

Cyber TSCM also includes detection of spyware, malware and malicious payloads via software installed on the devices &/or networks. As well, it includes detection of  hybrid eavesdropping devices.

ComSec LLC was the first privately owned counterespionage company to be published as identifying the need for “CYBER TSCM.” More specifically, ComSec identified Cyber TSCM as a more accurate depiction of the best level of TSCM service to address emerging cyber and hybrid technical surveillance threats.

Why Is Cyber TSCM Important?

Securing information and managing cyber risk in an increasingly connected, data driven world is critical. Data is continually created, transferred or stored on devices and/or on networks. Without the proper security, an eavesdropper can exploit the networks, devices and/or connections to steal valuable data and/or compromise privacy. Smartphones, remote cloud data storage, wi-fi camera systems, remote access security apps, smart assistants (e.g. Alexa), BYOD to work, GSM and hybrid bugging devices, etc. add complexity to the task of protecting confidential and/or private information. The appropriate technical security measures for detection and prevention of these threats must be implemented. ComSec LLC’s Cyber TSCM services address this need.

What is the Difference Between TSCM and Cyber TSCM?

TSCM is an acronym for Technical Surveillance Countermeasures. TSCM involves detecting traditional electronic eavesdropping devices. These are devices that generally require an eavesdropper, or their accomplice(s), to physically recover the device to access the collected information. TSCM also includes physical wire tapping where the eavesdropper can access the information from the tap location along the line. Ultimately, this means that an eavesdropper faces a high risk of detection when installing the device and/or when recovering the eavesdropping device(s) from the collection site.

Cyber TSCM involves detecting eavesdropping threats and vulnerabilities within Wi-Fi, Bluetooth & Cellular networks, the associated devices and the connection(s). Devices and mechanisms such as GSM bugs, IMSI catchers, device spyware/malware, rogue devices on Wi-Fi networks, compromised bluetooth devices, unauthorized networks, etc. are included. Generally, the cyber eavesdropper (or their accomplice) faces a lower risk of detection since they do not have to return to the collection site to recover the information. As well, access to information can be long term if the eavesdropping devices are energy efficient (sound or motion activated), or the cyber access cannot be quickly stopped. And, the use of a virtual private network (VPN), phone number spoofing apps, or generic email addresses can mask the digital trail (and identity) of the eavesdropper.

Why Is Cyber TSCM Such an Important Element of a Cybersecurity Program?

The personnel who maintain the cybersecurity program are trained to detect network threats. They are not trained, or equipped, to detect eavesdropping devices. As well, eavesdropping exploitations of the cellular network or use of hybrid eavesdropping devices are not within their area of expertise. If your cybersecurity program does not include Cyber TSCM, you could be missing a very credible threat. For instance, eavesdropping devices can be used to push data out over the cellular network. And, hybrid eavesdropping devices can be disguised as harmless data cables. The results of these types of eavesdropping attacks can just as devastating as an IT related cybersecurity issue.

ComSec’s Cyber TSCM Inspection detects electronic eavesdropping devices and/or technical intrusions via remote access attack. These attacks are conducted via GSM, 3G & 4G, and provide remote cellular access and collection of your confidential information. Cyber intruders use these attacks to gain unauthorized access (from anywhere in the world) to your data via a mobile phone signal. ComSec LLC has an advanced suite of Cyber Counterespionage – Cyber TSCM services designed to detect anomalies associated with GSM, 3G & 4G and Advanced Persistent Threats (APT) attacks.

What are Hybrid Devices?

Hybrid devices are devices that are commonly found in offices or homes which have been re-purposed as eavesdropping devices. So, while the device would not be suspect because of its appearance and/or location, it is actually a very credible threat that can only be detected through use of Cyber TSCM methods.

Hybrid Threat Example:  A CAT 5 cable (just like this one) plugged into the back of your phone or computer with an embedded “fiber optic microphone” which is plugged into an access port or phone, etc. in your office, conference room or home. This cyber eavesdropping threat can pick up a whisper from across a room. The information gained from this type of device may be listened to via real time, via digital recording device, or boosted out over the cellular, wi-fi or bluetooth network.  How long do you think it would take to install this eavesdropping device which simply needs to be “plugged” in? This is a very serious eavesdropping threat that could stay in place, undetected for YEARS if you do not perform routine Cyber TSCM surveys.
