Telekopye: Chamber of Neanderthals’ secrets and techniques


We just lately revealed a blogpost about Telekopye, a Telegram bot that helps cybercriminals rip-off individuals in on-line marketplaces. Telekopye can craft phishing web sites, emails, SMS messages, and extra.

Within the first half, we wrote about technical particulars of Telekopye and hinted at hierarchical construction of its operational teams. On this second half, we deal with what we have been in a position to study Neanderthals, the scammers who function Telekopye, their inside onboarding course of, completely different tips of commerce that Neanderthals use, and extra.

Key factors of this blogpost:

  • How aspiring Neanderthals be part of Telekopye teams.
  • Detailed view of the entire scamming operation from the Neanderthals’ perspective.
  • Evaluation of the rip-off situations and what every Neanderthal has to do with a purpose to achieve success.
  • The instruments utilized by senior Neanderthals.
  • Insights into tips that Neanderthals use to lure their victims.
  • Highlights from an interview with one of many Telekopye directors.

Overview

Not too long ago, we revealed an evaluation of Telekopye; on this follow-up blogpost, we deal with the Neanderthals’ techniques and modus operandi. Our data comes from three essential sources:

  1. supply code of the bot itself,
  2. evaluation of Neanderthals’ conversations from scamming teams we’ve infiltrated, and
  3. our evaluation of Neanderthals’ inside documentation – a set of paperwork, graphs, footage, and extra – that they use as their very own private data base. Such data is supplied to newcomers to assist them with onboarding.

We’d additionally prefer to thank Flare, who helped us in our analysis.

Becoming a member of a bunch

Telekopye teams recruit new Neanderthals by way of commercials in many alternative channels, together with underground boards. These commercials clearly state the aim: to rip-off on-line market customers, as seen in Determine 1.

Aspiring Neanderthals are required to fill out an software, answering primary questions like the place they realized in regards to the group and what expertise they’ve on this line of “work”. If accepted by current group members with sufficiently excessive position, the brand new Neanderthals can begin utilizing Telekopye to its full extent. Moreover, each Neanderthal is required to hitch two channels: a bunch chat the place Neanderthals talk and the place guidelines and manuals are stored, and a separate channel the place transaction logs are stored. The method is demonstrated in Determine 2.

Forms of scams

There are three essential rip-off situations:

1. Vendor, internally known as 1.0.

2. Purchaser, internally known as 2.0.

3. Refund.

Determine 3 is the creation menu for the primary two rip-off situations, the place column 1 on the backside represents Vendor scams (1.0). The Refund rip-off state of affairs is then tied to every rip-off state of affairs individually. These rip-off varieties are described within the following subsections.

Figure 3 Example of creation menu
Determine 3. Instance of creation menu for various rip-off situations

Vendor rip-off

On this state of affairs, Neanderthals pose as sellers and attempt to lure unsuspecting Mammoths into shopping for some non-existent merchandise. When a Mammoth reveals curiosity within the merchandise, the Neanderthal persuades the Mammoth to pay on-line relatively than in individual. If the Mammoth agrees, the Neanderthal supplies a hyperlink to a phishing web site supplied by Telekopye and punctiliously crafted to resemble the fee web page of the professional on-line market itemizing the reputed merchandise. In contrast to the professional internet web page although, this web page asks for a web-based banking login, bank card particulars (typically together with steadiness), or different delicate data. If the Mammoth enters this knowledge, the phishing web site routinely steals it. Apparently, this knowledge doesn’t change into obtainable to the Neanderthal providing the merchandise on the market, however is processed by different Neanderthals. Determine 4 reveals the Telekopye menu with already created phishing hyperlinks and Determine 5 demonstrates the communication throughout this rip-off state of affairs.

Purchaser rip-off

On this state of affairs, Neanderthals pose as consumers and so they analysis a Mammoth to focus on. They present curiosity within the merchandise a Mammoth is promoting and declare they already paid by way of the offering platform. The Neanderthals proceed to ship the Mammoths electronic mail or SMS messages (created by way of Telekopye) with a hyperlink to a fastidiously crafted phishing web site (additionally created by way of Telekopye; see Determine 6), claiming the Mammoth must click on this hyperlink with a purpose to obtain their cash from the platform. The remainder of the state of affairs is similar to the Vendor rip-off with slight variations throughout dialog (depicted in Determine 7).

Figure 7 Example of conversation for Buyer scam scenario
Determine 7. Instance of dialog for the Purchaser rip-off state of affairs

Refund rip-off

On this state of affairs, Neanderthals create a scenario the place the Mammoth is anticipating a refund after which sends them a phishing electronic mail with a hyperlink to the phishing web site, as soon as extra serving the identical function. Neanderthals both ship such emails to Mammoths they didn’t contact earlier, relying on them getting grasping and making an attempt to get this “refund” or they mix it with the Vendor rip-off state of affairs – when Mammoths complain that they didn’t obtain their items, Neanderthals ship them refund phishing emails in an try to rip-off them for a second time.

Modus operandi

Now that we have now described the completely different rip-off situations, let’s have a look at what data the Neanderthals have gathered all through the years of their operation. Their inside documentation consists of pictures, graphs, quick guides, and even complicated paperwork – the desk of contents of 1 such doc is illustrated in Determine 8.

Figure 8 Table of contents
Determine 8. Desk of contents from onboarding supplies (translated from Russian)

We additionally found that there are two sorts of Neanderthals. The primary form writes to each attainable Mammoth and the opposite one is far pickier in relation to in search of a possible Mammoth. There’s a little bit of rivalry between them because the extra cautious form argues that the “reckless” habits of the much less cautious scammers may deliver a bit extra revenue, nevertheless it creates rather more public consciousness.

Preparation

Getting ready for a rip-off differs based mostly on the chosen state of affairs. For the Vendor rip-off state of affairs, Neanderthals are suggested to arrange further pictures of the merchandise to be prepared if Mammoths ask for extra particulars. If Neanderthals are utilizing footage they downloaded on-line, they’re presupposed to edit them to make picture search tougher.

For the Purchaser rip-off state of affairs, the important thing a part of a Neanderthal’s preparation is how they select the Mammoth. Over time, Neanderthals have created pointers to observe when selecting their targets – they think about gender, age, expertise in on-line marketplaces, ranking, evaluations, variety of accomplished trades, and lots of extra indicators.

Market analysis

In nearly each group of Neanderthals, we are able to discover references to manuals with on-line market analysis from which Neanderthals draw their methods and conclusions. The supply of this analysis is normally a examine from 2017 by Avito and Information Perception company. Determine 9 illustrates the outcomes of 1 such analysis, depicting graphs of gender, age, expertise, and revenue distribution on a selected on-line market.

Determine 9. Neanderthals’ evaluation of a typical purchaser (translated from Russian)

In the course of the Purchaser rip-off state of affairs, Neanderthals select their targets based mostly on the kind of objects they’re promoting. For example, some teams keep away from electronics utterly. Alternatively, cell units are a valued class for different teams. The value of the merchandise can be essential – if too excessive, then Neanderthals is not going to goal such Mammoths, as they imagine that the Mammoths’ vigilance shall be a lot larger by default. Manuals suggest that Neanderthals, within the Purchaser rip-off state of affairs, choose objects with a value between 1,000 to 30,000 rubles (€9.50 to €290 as of 20th October, 2023).

The placement of the Mammoth can be essential. Neanderthals focus extra on richer cities the place they anticipate extra listings and other people not retaining such a detailed eye on their very own funds.

Lastly, the scammers take the day of the month into consideration too. They intention at days proper after individuals obtain their paychecks, as they naturally anticipate they will have extra money of their financial institution accounts.

Net scraping

Neanderthals make the most of internet scrapers to rapidly go although many on-line market listings and choose an ideal Mammoth who will fall for the rip-off; that is, as we have now already written, a vital preliminary a part of the Purchaser rip-off state of affairs.

We aren’t conscious of customized internet scrapers carried out by Neanderthals, however their documentation mentions a couple of supplied as professional companies. Neanderthals scrape the focused market for listings, particulars of things, and consumer data, which leads to a CSV or XML file. Neanderthals then use the outcomes to rapidly discover the best targets. We offer an instance of such a file in Determine 10.

Determine 10. Parsed information from Avito web site within the class “cellphones” (translated from Russian)

Person rankings and expertise are of specific curiosity to Neanderthals, as they use this data to keep away from targets that they deem prone to spot the rip-off.

Avoiding in-person supply

For security causes, many Mammoths desire each in-person fee and in-person supply for bought items. That poses a difficulty for Neanderthals as they should persuade Mammoths to agree to make use of a supply service and on-line fee, in order that they’ll direct them to the phishing web site. Normally, they declare they’re too distant or that they’re leaving the town for a enterprise journey for a couple of days. On the identical time, they attempt to look very within the merchandise to extend the probabilities that the Mammoth will comply with their suggestion.

Phishing internet web page hyperlink supply

Many professional on-line marketplaces have an built-in chat function and, alongside, moderation in place. Sending somebody a hyperlink by means of such a chat is normally a crimson flag and will very properly end in a ban. Neanderthals attempt to overcome this impediment by persuading Mammoths to proceed their dialog on a distinct chat platform that has much less monitoring.

Their arguments are similar to these in opposition to in-person supply. They declare that they should go away their residence and can’t entry the chat from their cell phone, however are in a position to proceed their discuss on one of many chat apps.

By their very own statistics, Neanderthals declare that about 50% of Mammoths will comply with a platform change and 20% of these will fall for the rip-off. This leads to a ten% success price total.

One other favored methodology of supply is utilizing electronic mail or SMS. Telekopye is ready to rapidly generate convincing phishing messages. Neanderthals use tips (a few of them illustrated in Determine 11) to be taught Mammoths’ electronic mail addresses or cellphone numbers with a purpose to ship them such messages. The benefit of this method is that asking for a cellphone quantity or electronic mail tackle will possible not set off any crimson flags for neither Mammoth nor chatting platform and the Neanderthal doesn’t want to steer the Mammoth to switch to a distinct chat platform.

Communication

No AI is utilized by Telekopye. This can be stunning, however Neanderthals imagine that their method is superior and fewer prone to be noticed by monitoring mechanisms. In consequence, the huge portion of their inside documentation is targeted on communication methods to attain the perfect outcomes.

Incomes the Mammoth’s belief is essential to the success of a rip-off. Neanderthals typically deliberately don’t instantly reply to each message however wait (typically even a couple of hours) to create the phantasm that they’re busy with common on a regular basis life. Talking of time: they attempt to adapt to the Mammoth’s time zone so as to not increase suspicion.

They typically interact in chitchat first; they might even share a faux private story. The entire function is to search for crimson flags – indicators that will inform the Neanderthal that the Mammoth is simply too suspicious or skilled. Since Neanderthals are targeted on revenue, they don’t need to spend time on Mammoths who find yourself recognizing the lure.

One other nice instance is that when Neanderthals make the most of the Purchaser rip-off state of affairs, they guarantee Mammoths that they’ve already paid for the merchandise. This, mixed with the design of the phishing electronic mail that guarantees fast cash retrieval, leads to Mammoths being much less vigilant.

Skilled Neanderthals present newcomers with full conversations to take inspiration in; one such instance is supplied in Determine 12.

Determine 12. Prompt dialog with a Mammoth (translated from Russian)

Neanderthals solely tolerate a sure stage of resistance from Mammoths – in the event that they deem the rip-off isn’t prone to succeed, they transfer to a distinct goal. Nonetheless, in the event that they really feel like they’ve nearly received, they’re very persuasive. An ideal instance is their documented method to conditions the place they efficiently harvest the Mammoth’s delicate knowledge, however both the financial institution blocks the transaction or there are inadequate funds. In that case, Neanderthals might go so far as asking the Mammoth to make use of a member of the family’s card and even name their financial institution and authorize the switch themselves.

Neanderthals are able to reply many sudden questions concerning the legitimacy of their requests (see Determine 13).

Translation

As this operation targets Mammoths internationally, Neanderthals have to create the phantasm that they communicate the Mammoth’s language properly sufficient. It’s fairly frequent to come across Russian-speaking Neanderthals who can write in English. Apparently, we have been in a position to cross-reference the Telegram nicknames of many Neanderthals with language-learning platform profiles. These accounts normally acknowledged that the proprietor speaks Russian and English. Clearly, the connection may be coincidental.

For a few years Neanderthals used Google Translate. Since at the least 2021, Neanderthals moved in direction of different translators, comparable to DeepL, as (of their opinion) it understands context higher.

Apart from utilizing translators, they’ve created many translation tables over time, with verified translations of frequent phrases into a number of languages. These translations are mostly from Russian to European languages (see Determine 14). Neanderthals simply copy and paste these translated sentences into the chat with the Mammoth.

Determine 14. Instance of Portuguese-Russian and Romanian-Russian translation tables

Group particular options

We also needs to point out that completely different teams have completely different quality-of-life enhancements to Telekopye. For instance, when producing a phishing hyperlink (a end result may be seen in Determine 15), Neanderthals from one in every of these teams are requested a number of questions that allow them to have sure diploma of customization of every phishing web site. Probably the most attention-grabbing is the query about guide/automated phishing website era. Within the case of guide era, the Neanderthal should specify all data wanted to create the phishing web site. For Neanderthals posing as consumers, this takes from 10 to fifteen questions (Determine 16).

Determine 15. Instance of automated phishing web site creation course of by Telekopye, the place Neanderthal poses as a purchaser
Figure 16 Manual of phishing link creation process
Determine 16. Guide phishing hyperlink creation course of

Within the case of automated web page era, the Neanderthal solely must specify the URL of the merchandise to “purchase” and to reply 5 questions (like what the client’s identify and cellphone quantity are). Telekopye then scrapes all data from the web site and creates the phishing web site.

Anonymity and evasion

Neanderthals imagine their teams are filled with “rats” (for instance, legislation enforcement or researchers). So, they religiously follow the principles, primarily no probing for data that would establish different members of the group. Breaking such guidelines might very properly end in being banned. The golden rule is “work extra discuss much less”. As well as, they’re inspired to make use of VPNs, proxies, and TOR to remain protected. Neanderthals present newcomers with in depth guides and even interact in heated discussions over what packages or companies to make use of and why, together with browser preferences. Some Neanderthals even make the most of Orbot, a TOR variant for Android.

Cash

Neanderthals want to cover not solely their identities and placement, but in addition their cash. Naturally, cryptocurrencies are the reply to that. We weren’t ready to attract any conclusions concerning cryptocurrency desire.

Lastly, Neanderthals desire companies for which they’ll register utilizing solely a cell phone quantity. They think about this the perfect method, since it’s comparatively straightforward to purchase a SIM card whereas not disclosing their id.

Bypassing automated detection

On-line market scams are nothing new. Over time, the platforms offering these companies have carried out a variety of methods to counter scammers and enhance their prospects’ safety. The Neanderthals are conscious of this and proceed to experiment with completely different approaches to beat the platforms’ moderation insurance policies. One early and relatively silly try was to make the most of Google Varieties to phish private data from Mammoths (as seen in Determine 17). Contemplating the data they focused, the purpose was to acquire a method to speak by means of a distinct channel – electronic mail or SMS – the place strict moderation wouldn’t happen.

These days, nearly all Neanderthals attempt to switch their Mammoths to much less policed, professional chat platforms. Neanderthals select them as a result of they imagine banning accounts there takes time. Moreover, sending varied hyperlinks over chat platforms is frequent apply relatively than suspicious habits. As a bonus, nearly everyone is acquainted with such purposes, so Neanderthals don’t have to clarify how they work.

Regardless of contemplating these platforms a lot safer, Neanderthals tread fastidiously nonetheless. They keep away from sending too many messages in a brief time frame and attempt to personalize messages for various Mammoths – Telekopye aids them vastly on this effort.

Exploring new territories: Actual property rip-off

Among the Neanderthals’ teams point out a distinct sort of rip-off state of affairs – one which targets actual property renters. The rip-off works as follows. In the course of the preparation stage, Neanderthals write to a professional proprietor of an house, pretending to have an interest and ask for varied particulars, comparable to further footage and what sort of neighbors the house has. The Neanderthals then take all this data and create their very own itemizing on one other web site, providing the house for lease. They minimize the anticipated market value by about 20%. The remainder of the state of affairs is equivalent to Vendor rip-off state of affairs – the Neanderthal waits for a Mammoth to point out curiosity, and directs the Mammoth to pay a reservation payment by way of a hyperlink that, in fact, truly factors to a phishing web site.

Because of ESET’s telemetry we discovered that the phishing web sites used on this rip-off state of affairs are suspiciously much like those Telekopye creates for the Purchaser and Vendor situations. This, mixed with the rip-off being marketed by Telekopye teams, leads us to imagine that there’s a connection. Nonetheless, we neither infiltrated any group specializing on this state of affairs nor obtained a Telekopye variant designed for it.

Interview

When crawling by means of completely different manuals, teams, and extra supplies, we discovered an interview with a Telekopye administrator that was performed on the finish of 2020. This helped us get a singular perception into the thoughts of a high-ranked Neanderthal. The interviewed Telekopye administrator operated a Telekopye group specializing in educating new Neanderthals.

The administrator is at one level requested how he sees the way forward for this line of “work”. To that, he responds that “On-line market scams will all the time be current. It’s a lot more durable [to scam] than it was once due to banning insurance policies on completely different websites. However it’s simply not attainable to cease all phishing on these websites”. He additionally says that he doesn’t rip-off anymore. He simply acquired uninterested in it and now works solely as administrator/tutor and that’s the reason why his group is so distinctive. “I don’t concern Mammoths. Each different Mammoth will threaten you after they notice they’ve been scammed. Apparently, everybody as of late is a spouse or a good friend of a minister of inside affairs”, says the administrator.

When requested whether or not he is considering creating a brand new rip-off challenge, he says that he doesn’t have time for that. He moderates two channels, has an energetic life-style, does lots of coaching, and he has solely 4 hours a day at residence.

He additionally confesses that he’s totally conscious that this sort of a job isn’t trustworthy however finds a typical excuse for himself. “… some individuals will consistently pay for hyperlinks, and somebody will consistently throw them. Whoever tries arduous in life will succeed.”. On prime of that he says that if he feels sorry for Mammoth, he asks himself: “Why am I scamming them within the first place? Properly… I solely steal from the wealthy (analysis notice: Mammoths that most likely have at the least €200 of their account) and if my conscience have been that fragile, I’d go work as a supply man”.

Conclusion

On this second installment devoted to Telekopye, we have now targeted on what we realized about Neanderthals. Because of getting access to each their inside communication and their data base, we have now supplied not solely descriptions of various rip-off situations, however primarily a singular perception into their modus operandi and mindset.

Now we have demonstrated how the admission course of for newcomers seems to be like and the way Telekopye aids Neanderthals of their each day work. As well as, we have now proven that they most likely are experimenting with actual property scams as properly.

On-line market scams are possible not going away. As we demonstrated in the primary installment, we have been in a position to uncover dozens of teams working Telekopye. That stated, by having our distinctive perception into the scammers’ operation, we imagine loads may be realized with a purpose to shield customers of such platforms from hurt.
