In the first article discussing our ongoing Chinese Telegram Group Investigation, we revealed that a Chinese Telegram group is selling date rape drugs, in the form of chewing gum, among other options, with payments available in cryptocurrency. This is merely one of many categories provided within this specific group. The same group offers a wide range of covert surveillance devices, most notably, disguised pinhole cameras, all available for direct purchase with USDT, precisely like the date rape drugs they sell. 

What We Uncovered 

The group’s advertisement promised availability of ‘various pinhole cameras, no-hole cameras, true 4K quality, through hidden recording devices, no-light night vision, remote access. Custom orders accepted.’ Following the advertisement, the admin also reminds group members of the availability of date rape drugs and other incapacitating drugs.

The group’s admin has shared numerous demo videos, with one showcasing a pinhole camera disguised as a lighter. The description reads: ‘Function: the normal lighter function remains unchanged. Bottom hidden camera function, live streaming can be viewed on mobile phone, recording can be done on mobile phone’. 

This is just one item among a catalogue of disguised recording devices. The range of devices available is staggering, with a wide variety of everyday objects listed as items with concealed devices inside. The list includes wall sockets, apple watches, hats, car keys, chandeliers, electric clocks and tissue boxes. 

The variety of options indicates that this is not a small-scale operation. The admin regularly directs buyers to a ‘24 hour customer service’ contact, underscoring the scale and organisation behind the group. 

Why These Devices Matter

Considering the context of these items, the implications of the sale of hidden cameras is just as concerning as the sale of date rape drugs. Upon closer inspection into this group, it is clear that these cameras are not being sold for benign purposes such as home security or self protection. In both cases, emphasis is placed on the disguised secretive nature of the items, ensuring victims of both the secret cameras and the drugs are completely blindsided. 

Our findings point to a highly probable link between these secret hidden cameras, and the creation and sale of secretly recorded footage. 

We will cover this more deeply at the final stage of our investigation, which will focus on the availability of a connected group that openly advertises access to videos filmed in hotel rooms, certainly without the knowledge and or consent of the victims recorded. The existence of such cameras, combined with the offerings of drugs and hotel room footage, paints a grim picture of a criminal ecosystem designed to facilitate the exploitation of individuals in numerous ways worldwide. 

What This Means For Crypto

Just like the sale of narcotics, the trade of secret surveillance equipment of this kind raises concerns about the role crypto plays in enabling these underground economies. The group’s willingness to accept USDT for such transactions demonstrates how stablecoins are becoming the preferred medium of exchange for illicit actors. 


For legitimate businesses in the crypto ecosystem such as exchanges, payment processors, and wallet providers, this underscores a familiar yet urgent reality: without effective transaction monitoring, there is a serious risk of facilitating transactions, or becoming a conduit linked to organised criminal operations. 

The challenge is not merely about preventing money laundering or criminal activity. Halting the flow of funds that enable exploitation, abuse, and invasion of privacy at a global scale is the ultimate goal. 

As cases like this reveal, dark web forums and encrypted groups continue to use cryptocurrency as their lifeline. 

The responsibility falls on the compliance teams and regulators alike to ensure that the technology is not misused. Without vigilance, the same blockchain innovations that promise financial freedom risk being co-opted by those who seek to harm others. 

In the final part of the series, we will uncover how this same group is connected to a scheme monetising footage collected from hidden cameras: selling access to videos of unsuspecting hotel guests and turning privacy violations into a profitable business. 

FAQs

Why is Telegram used to sell illicit products? 

Telegram has become a hub for illicit product sales due to its encrypted messaging, private groups, and large user base. Criminal networks exploit these features to advertise and distribute items, such as date rape drugs and hidden surveillance cameras, while remaining difficult to trace. Unlike traditional marketplaces, Telegram allows sellers to quickly create new groups, share such demo videos, and even offer customer service, under the cover of anonymity. Hence, it has become a preferred platform for illicit activity. 

Why does cryptocurrency play such a role in illicit activity? 

Cryptocurrency, particularly stablecoins like USDT (Tether) play a central role because it enables fast, borderless, and pseudonymous payments. Illicit actors avoid traditional banking systems which are subject to AML checks and regular scrutiny, and instead rely on crypto to complete sales of drugs or covert spy cameras instantly. Stablecoins are especially popular because they maintain a consistent value, making them reliable as cash while still difficult to trace. 

What risks do illicit telegram groups accepting cryptocurrency pose to legitimate crypto businesses? 

For exchanges, payment processors, and wallet providers, these activities present major crypto compliance risk. Without efficient blockchain monitoring and Know Your Transaction tools such as nominis.io‘s Nominis Vue, businesses may unknowingly process payments linked to drug trafficking, dark web transactions, privacy-invasive equipment, or even more serious life threatening crimes (known as black flag risks). 

This can result in regulatory penalties, reputational damage, potential sanctions violations or jail time for the most serious criminal cases. The lesson for legitimate businesses is clear: robust crypto compliance frameworks are essential to incorporate, to prevent becoming an indirect conduit for illicit finance and organised crime.
