Telekopye overview

Telekopye is a toolkit that operates as a Telegram bot, primarily serving as a Swiss Military knife for turning on-line market scams into an organized illicit enterprise. It’s utilized by dozens of rip-off teams, with as much as hundreds of members, to steal hundreds of thousands from Mammoths, as they name the focused patrons and sellers. Neanderthals, as we name the scammers, require little to no technical information – Telekopye takes care of every thing in a matter of seconds.

Found by ESET Analysis in 2023, Telekopye has been in use since a minimum of 2016, with victims everywhere in the world. A number of leads level to Russia because the nation of origin of the bot’s creator(s) and in addition the scammers utilizing it. Telekopye is designed to focus on a big number of on-line companies in Europe and North America, akin to OLX, Vinted, eBay, Wallapop, and others. On the time of writing, we now have counted roughly 90 totally different companies being focused by the scams.

Neanderthals – members of any Telegram group using Telekopye – achieve entry to the bot’s UI, which permits easy technology of phishing emails, SMS messages, net pages, and different options.

Telekopye teams have a business-like operation, with a transparent hierarchy, outlined roles, inside practices – together with admission and mentoring processes for newcomers – mounted working hours, and fee payouts for Telekopye directors. The Staff performing the scams should flip over any delicate info stolen, and don’t really steal any cash – that’s managed by different roles within the group. Every group retains a clear chat of all transactions, seen to all members.

Neanderthals make the most of two principal situations for concentrating on on-line marketplaces – one the place they pose as sellers and one other, rather more frequent, the place they pose as patrons. Each situations finish with the sufferer/Mammoth coming into fee card info or on-line banking credentials right into a phishing net web page mimicking a fee gateway.

Not too long ago, Telekopye teams have expanded their concentrating on by including help for scamming customers of common on-line platforms for reserving lodging, which we cowl within the following part.

Branching out to lodging reserving platforms

In 2024, Telekopye teams have expanded their scamming playbook with schemes concentrating on customers of common on-line platforms for resort and residence reservations, akin to Reserving.com and Airbnb. They’ve additionally elevated the sophistication of their sufferer choice and concentrating on.

Concentrating on with a twist

On this new rip-off state of affairs, Neanderthals contact a focused consumer of one in every of these platforms, claiming that there’s a difficulty with the consumer’s reserving fee. The message comprises a hyperlink to a well-crafted, legitimate-looking net web page mimicking the abused platform.

The web page comprises prefilled details about a reserving, such because the check-in and checkout dates, value, and placement. This comes with a troubling twist: the information supplied on the fraudulent pages matches actual bookings made by the focused customers.

The Neanderthals obtain this by using compromised accounts of authentic motels and lodging suppliers on the platforms, which they most definitely entry through stolen credentials bought on cybercriminal boards. Utilizing their entry to those accounts, scammers single out customers who not too long ago booked a keep and haven’t paid but – or paid very not too long ago – and call them through in-platform chat. Relying on the platform and the Mammoth’s settings, this results in the Mammoth receiving an electronic mail or SMS from the reserving platform.

This makes the rip-off a lot tougher to identify, as the data supplied is personally related to the victims, arrives through the anticipated communication channel, and the linked, pretend web sites look as anticipated. The one seen signal of one thing being amiss are the web sites’ URLs, which don’t match these of the impersonated, authentic web sites. Neanderthals may use their very own electronic mail addresses for the preliminary communication (quite than the compromised accounts), during which case the emails is likely to be extra simply acknowledged as malicious.

As soon as the goal fills out the shape on the phishing web page (Determine 1), they’re dropped at the ultimate step of the “reserving” – a type requesting fee card info (Determine 2). As within the market scams, card particulars entered into the shape are harvested by the Neanderthals and used to steal cash from the Mammoth’s card.

In response to ESET telemetry, the sort of rip-off began gaining traction in 2024. As seen in Determine 3, the accommodation-themed scams noticed a pointy uptick in July, surpassing the unique Telekopye market scams for the primary time, with greater than double the detections throughout that month. In August and September, the detection ranges for the 2 classes evened out.

As this improve coincides with the summer time vacation season within the focused areas – prime time for benefiting from folks reserving stays – it stays to be seen whether or not this development will proceed. Trying on the total 2024 information, we will see that these newer scams have amassed roughly half of the detection numbers of {the marketplace} variants. That is noteworthy contemplating that the newer scams concentrate on two platforms solely, in comparison with the wide range of on-line marketplaces focused by Telekopye.

Superior Telekopye options

All through our monitoring of Telekopye, we’ve noticed that totally different Telegram teams implement their very own superior options into the toolkit, aimed toward dashing up the rip-off course of, bettering communication with targets, defending phishing web sites in opposition to disruption by rivals, and different targets.

Automated phishing web page technology

To hurry up the method of making rip-off supplies for posing as patrons on marketplaces, Neanderthals carried out net scrapers for common focused platforms. With these, solely the URL to the product is required, as an alternative of getting to manually fill out a questionnaire in regards to the focused Mammoth and product in query. Telekopye parses the net web page and extracts all mandatory info robotically, offering a major speedup for the scammers.

Interactive chatbot with on-the-fly translation

Neanderthals keep a big assortment of predefined solutions to questions generally requested by Mammoths. These are translated into numerous languages and saved as a part of inside documentation, with the translations perfected over time.

Neanderthals usually use these predefined phrases to attempt to direct the Mammoth to the phishing web site, which comes with a chatbot within the decrease proper nook. Any message the Mammoth enters into the chat is forwarded to the Neanderthal’s Telegram chat, the place it’s robotically translated. Automated translation of Neanderthals’ messages isn’t supported – Neanderthals translate their messages manually, normally utilizing DeepL. Determine 3 reveals how such an interplay seems to be from the Neanderthal’s and Mammoth’s factors of view.

Anti-DDoS measures

The overwhelming majority of the phishing web sites are serviced by Cloudflare, counting on that service’s added safety, primarily in opposition to crawlers and computerized evaluation. Apparently, among the Telekopye phishing web sites additionally include DDoS safety included. In response to the Neanderthals’ information base, which we obtained by infiltrating their ranks, this characteristic goals to guard in opposition to assaults by rival teams. These are typically launched as a method to disrupt a competitor’s operations for a brief interval.

Regulation enforcement operations

In late 2023, after ESET Analysis had printed its two-part sequence on Telekopye, Czech and Ukrainian police arrested tens of cybercriminals using Telekopye, together with the important thing gamers, in two joint operations. Each operations had been aimed in opposition to an unspecified variety of Telekopye teams, which had amassed a minimum of €5 million (roughly US$5.5 million) since 2021, based mostly on police estimates.

Moreover the plain success in disrupting such legal actions, the arrests supplied new insights into the teams’ workings, most notably recruitment and employment practices. The teams in query had been managed, from devoted workspaces, by middle-aged males from Japanese Europe and West and Central Asia. They recruited folks in troublesome life conditions, by job portal postings promising “simple cash”, in addition to by concentrating on technically expert international college students at universities.

Some perpetrators confessed that in addition they participated in one other rip-off group, just like the Telekopye ones, that utilized name facilities. The police realized that the recruits in that operation had been usually stripped of their passports and private IDs to make quitting very troublesome. Additional, the managers typically went as far as to threaten the workers and their relations. This chilling growth places these operations into a totally totally different mild.
