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 1000’s of members, to steal thousands and thousands from Mammoths, as they name the focused consumers and sellers. Neanderthals, as we name the scammers, require little to no technical data – Telekopye takes care of every thing in a matter of seconds.

Found by ESET Analysis in 2023, Telekopye has been in use since at the very least 2016, with victims everywhere in the world. A number of leads level to Russia because the nation of origin of the bot’s writer(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, corresponding to OLX, Vinted, eBay, Wallapop, and others. On the time of writing, we now have counted roughly 90 completely 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 era of phishing emails, SMS messages, internet pages, and different options.

Telekopye teams have a business-like operation, with a transparent hierarchy, outlined roles, inner practices – together with admission and mentoring processes for newcomers – mounted working hours, and fee payouts for Telekopye directors. The Employees performing the scams should flip over any delicate data stolen, and don’t truly 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 consumers. Each situations finish with the sufferer/Mammoth coming into fee card data or on-line banking credentials right into a phishing internet 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 lodge and condo reservations, corresponding to Reserving.com and Airbnb. They’ve additionally elevated the sophistication of their sufferer choice and concentrating on.

Focusing on with a twist

On this new rip-off situation, Neanderthals contact a focused person of considered one of these platforms, claiming that there’s a difficulty with the person’s reserving fee. The message comprises a hyperlink to a well-crafted, legitimate-looking internet 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 site. This comes with a troubling twist: the data offered 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 probably entry through stolen credentials bought on cybercriminal boards. Utilizing their entry to those accounts, scammers single out customers who just lately booked a keep and haven’t paid but – or paid very just lately – and phone 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 knowledge offered 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 additionally use their very own electronic mail addresses for the preliminary communication (somewhat than the compromised accounts), through which case the emails could 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 kind requesting fee card data (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.

Based on ESET telemetry, this 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 enhance coincides with the summer time vacation season within the focused areas – prime time for benefiting from individuals reserving stays – it stays to be seen whether or not this pattern 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 give attention to two platforms solely, in comparison with the big variety of on-line marketplaces focused by Telekopye.

Superior Telekopye options

To hurry up the method of making rip-off supplies for posing as consumers on marketplaces, Neanderthals carried out internet scrapers for common focused platforms. With these, solely the URL to the product is required, as a substitute 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 needed data robotically, offering a major speedup for the scammers.

Interactive chatbot with on-the-fly translation

Neanderthals preserve a big assortment of predefined solutions to questions generally requested by Mammoths. These are translated into numerous languages and saved as a part of inner 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 will not be supported – Neanderthals translate their messages manually, often utilizing DeepL. Determine 3 exhibits how such an interplay seems 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 towards crawlers and computerized evaluation. Apparently, a number of the Telekopye phishing web sites additionally include DDoS safety included. Based on the Neanderthals’ data base, which we obtained by infiltrating their ranks, this function goals to guard towards assaults by rival teams. These are generally launched as a way 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 have been aimed towards an unspecified variety of Telekopye teams, which had accrued at the very least €5 million (roughly US$5.5 million) since 2021, primarily based on police estimates.

In addition to the apparent success in disrupting such legal actions, the arrests offered new insights into the teams’ workings, most notably recruitment and employment practices. The teams in query have been managed, from devoted workspaces, by middle-aged males from Jap Europe and West and Central Asia. They recruited individuals in tough life conditions, via job portal postings promising “simple cash”, in addition to by concentrating on technically expert overseas college students at universities.

Some perpetrators confessed that in addition they participated in one other rip-off group, much like the Telekopye ones, that utilized name facilities. The police discovered that the recruits in that operation have been typically stripped of their passports and private IDs to make quitting very tough.
