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 all the things in a matter of seconds.

Found by ESET Analysis in 2023, Telekopye has been in use since no less than 2016, with victims all around 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’ve 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, 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 – fastened working hours, and fee payouts for Telekopye directors. The Staff 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 most important situations for focusing on on-line marketplaces – one the place they pose as sellers and one other, far more widespread, 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.

Lately, Telekopye teams have expanded their focusing on by including assist for scamming customers of in style 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 focusing on customers of in style on-line platforms for lodge and house reservations, akin to Reserving.com and Airbnb. They’ve additionally elevated the sophistication of their sufferer choice and focusing on.

Focusing on with a twist

On this new rip-off situation, Neanderthals contact a focused consumer of considered one of these platforms, claiming that there’s a problem with the consumer’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 legit accommodations and lodging suppliers on the platforms, which they almost certainly entry by way of 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 speak to them by way of in-platform chat. Relying on the platform and the Mammoth’s settings, this results in the Mammoth receiving an e mail or SMS from the reserving platform.

This makes the rip-off a lot more durable to identify, as the knowledge offered is personally related to the victims, arrives by way of the anticipated communication channel, and the linked, faux 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, legit web sites. Neanderthals can also use their very own e mail addresses for the preliminary communication (relatively than the compromised accounts), during which case the emails may 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.

In accordance with 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 development will proceed. Trying on the general 2024 information, we are able to 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 wide range 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 applied internet scrapers for in style focused platforms. With these, solely the URL to the product is required, as an alternative of getting to manually fill out a questionnaire concerning the focused Mammoth and product in query. Telekopye parses the net web page and extracts all vital data robotically, offering a big 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 inner documentation, with the translations perfected through the years.

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 exhibits how such an interplay appears to be like 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 automated evaluation. Curiously, a few of the Telekopye phishing web sites additionally include DDoS safety included. In accordance with the Neanderthals’ data base, which we obtained by infiltrating their ranks, this characteristic goals to guard towards assaults by rival teams. These are generally launched as a method to disrupt a competitor’s operations for a brief interval.

Apart from the plain success in disrupting such prison 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 Japanese Europe and West and Central Asia. They recruited individuals in tough life conditions, by job portal postings promising “simple cash”, in addition to by focusing on technically expert overseas college students at universities.

Some perpetrators confessed that additionally they participated in one other rip-off group, much like the Telekopye ones, that utilized name facilities.
