We 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 capable of find out about Neanderthals, the scammers who function Telekopye, their inside onboarding course of, totally different tips of commerce that Neanderthals use, and extra.
Key factors of this blogpost:
- How aspiring Neanderthals be a part of Telekopye teams.
- Detailed view of the entire scamming operation from the Neanderthals’ perspective.
- Evaluation of the rip-off eventualities and what every Neanderthal has to do as a way 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
Lately, we revealed an evaluation of Telekopye; on this follow-up blogpost, we deal with the Neanderthals’ techniques and modus operandi. Our info comes from three important sources:
- supply code of the bot itself,
- evaluation of Neanderthals’ conversations from scamming teams we’ve infiltrated, and
- 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 info is offered to newcomers to help them with onboarding.
We might additionally wish to thank Flare, who helped us in our analysis.
Becoming a member of a gaggle
Telekopye teams recruit new Neanderthals by way of ads in many various channels, together with underground boards. These ads 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 discovered concerning the group and what expertise they’ve on this line of “work”. If permitted by present 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 gaggle 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.
Kinds of scams
There are three important rip-off eventualities:
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 eventualities, 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.
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 slightly than in individual. If the Mammoth agrees, the Neanderthal offers a hyperlink to a phishing web site offered by Telekopye and punctiliously crafted to resemble the fee web page of the reputable on-line market itemizing the reputed merchandise. In contrast to the reputable internet web page although, this web page asks for a web based banking login, bank card particulars (generally together with steadiness), or different delicate info. If the Mammoth enters this information, the phishing web site robotically steals it. Curiously, this information doesn’t turn 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 patrons 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 e-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 as a way 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).
Refund rip-off
On this state of affairs, Neanderthals create a state of affairs the place the Mammoth is anticipating a refund after which sends them a phishing e-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 attempting 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 and rip-off them for a second time.
Modus operandi
Now that we’ve described the totally different rip-off eventualities, 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, brief guides, and even complicated paperwork – the desk of contents of 1 such doc is illustrated in Determine 8.
We additionally found that there are two sorts of Neanderthals. The primary variety writes to each attainable Mammoth and the opposite one is way pickier with regards to on the lookout for a possible Mammoth. There’s a little bit of rivalry between them because the extra cautious variety argues that the “reckless” habits of the much less cautious scammers would possibly convey a bit extra revenue, but it surely creates way more public consciousness.
Preparation
Making ready for a rip-off differs primarily based 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 added particulars. If Neanderthals are utilizing footage they downloaded on-line, they’re speculated to edit them to make picture search harder.
For the Purchaser rip-off state of affairs, the important thing a part of a Neanderthal’s preparation is how they select the Mammoth. Through the years, Neanderthals have created tips to observe when selecting their targets – they take into account gender, age, expertise in on-line marketplaces, ranking, critiques, variety of accomplished trades, and plenty 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 study from 2017 by Avito and Information Perception company. Determine 9 illustrates the outcomes of 1 such analysis, depicting graphs of gender, age, expertise, and earnings distribution on a selected on-line market.
In the course of the Purchaser rip-off state of affairs, Neanderthals select their targets primarily based on the kind of gadgets they’re promoting. As an example, some teams keep away from electronics fully. However, cellular gadgets are a valued class for different teams. The value of the merchandise can be essential – if too excessive, then Neanderthals won’t goal such Mammoths, as they consider that the Mammoths’ vigilance shall be a lot larger by default. Manuals suggest that Neanderthals, within the Purchaser rip-off state of affairs, choose gadgets with a value between 1,000 to 30,000 rubles (€9.50 to €290 as of 20th October, 2023).
The situation 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 purpose at days proper after individuals obtain their paychecks, as they naturally anticipate they will have more cash of their financial institution accounts.
Internet scraping
Neanderthals make the most of internet scrapers to shortly go although many on-line market listings and choose an ideal Mammoth who will fall for the rip-off; that is, as we’ve already written, an important preliminary a part of the Purchaser rip-off state of affairs.
We’re not conscious of customized internet scrapers applied by Neanderthals, however their documentation mentions a number of provided as reputable providers. Neanderthals scrape the focused market for listings, particulars of things, and person info, which leads to a CSV or XML file. Neanderthals then use the outcomes to shortly discover the proper targets. We offer an instance of such a file in Determine 10.
Person rankings and expertise are of specific curiosity to Neanderthals, as they use this info to keep away from targets that they deem prone to spot the rip-off.
Avoiding in-person supply
For security causes, many Mammoths want each in-person fee and in-person supply for bought items. That poses a problem for Neanderthals as they should persuade Mammoths to agree to make use of a supply service and on-line fee, in order that they will direct them to the phishing web site. Often, they declare they’re too far-off or that they’re leaving the town for a enterprise journey for a number 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 reputable on-line marketplaces have an built-in chat function and, alongside, moderation in place. Sending somebody a hyperlink by way of such a chat is normally a pink flag and should very effectively lead to a ban. Neanderthals attempt to overcome this impediment by persuading Mammoths to proceed their dialog on a special chat platform that has much less monitoring.
Their arguments are similar to these towards in-person supply. They declare that they should depart their dwelling and can’t entry the chat from their cell phone, however are capable of proceed their speak 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 ends in a ten% success charge total.
One other favored methodology of supply is utilizing e-mail or SMS. Telekopye is ready to shortly generate convincing phishing messages. Neanderthals use tips (a few of them illustrated in Determine 11) to study Mammoths’ e-mail addresses or telephone numbers as a way to ship them such messages. The benefit of this method is that asking for a telephone quantity or e-mail tackle will probably not set off any pink flags for neither Mammoth nor chatting platform and the Neanderthal doesn’t want to influence the Mammoth to switch to a special chat platform.
Communication
No AI is utilized by Telekopye. This can be shocking, however Neanderthals consider that their method is superior and fewer prone to be noticed by monitoring mechanisms. In consequence, the huge portion of their inside documentation is concentrated on communication methods to attain one of the best 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 (generally even a number 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 elevate suspicion.
They typically interact in chitchat first; they could even share a faux private story. The entire function is to search for pink flags – indicators that will inform the Neanderthal that the Mammoth is just too suspicious or skilled. Since Neanderthals are targeted on revenue, they don’t need to spend time on Mammoths who find yourself recognizing the entice.
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 e-mail that guarantees fast cash retrieval, ends in Mammoths being much less vigilant.
Skilled Neanderthals present newcomers with full conversations to take inspiration in; one such instance is offered in Determine 12.
Neanderthals solely tolerate a sure stage of resistance from Mammoths – in the event that they deem the rip-off just isn’t prone to succeed, they transfer to a special 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 information, however both the financial institution blocks the transaction or there are inadequate funds. In that case, Neanderthals could 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 surprising questions concerning the legitimacy of their requests (see Determine 13).
Translation
As this operation targets Mammoths internationally, Neanderthals must create the phantasm that they converse the Mammoth’s language effectively sufficient. It’s fairly frequent to come across Russian-speaking Neanderthals who can write in English. Curiously, we have been capable of 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, corresponding to DeepL, as (of their opinion) it understands context higher.
In addition to utilizing translators, they’ve created many translation tables through the years, 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.
Group particular options
We also needs to point out that totally different teams have totally different quality-of-life enhancements to Telekopye. For instance, when producing a phishing hyperlink (a end result will 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. Essentially the most attention-grabbing is the query about guide/computerized phishing web site technology. Within the case of guide technology, the Neanderthal should specify all info wanted to create the phishing web site. For Neanderthals posing as patrons, this takes from 10 to fifteen questions (Determine 16).
Within the case of computerized web page technology, the Neanderthal solely must specify the URL of the merchandise to “purchase” and to reply 5 questions (like what the customer’s title and telephone quantity are). Telekopye then scrapes all info from the web site and creates the phishing web site.
Anonymity and evasion
Neanderthals consider their teams are filled with “rats” (for instance, legislation enforcement or researchers). So, they religiously stick with the principles, primarily no probing for info that would determine different members of the group. Breaking such guidelines could very effectively lead to being banned. The golden rule is “work extra speak much less”. As well as, they’re inspired to make use of VPNs, proxies, and TOR to remain protected. Neanderthals present newcomers with intensive guides and even interact in heated discussions over what packages or providers 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 site, 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 want providers for which they will register utilizing solely a cell phone quantity. They take into account this one of the best method, since it’s comparatively straightforward to purchase a SIM card whereas not disclosing their identification.
Bypassing computerized detection
On-line market scams are nothing new. Through the years, the platforms offering these providers have applied quite a few methods to counter scammers and improve their prospects’ safety. The Neanderthals are conscious of this and proceed to experiment with totally different approaches to beat the platforms’ moderation insurance policies. One early and slightly silly try was to make the most of Google Varieties to phish private info from Mammoths (as seen in Determine 17). Contemplating the data they focused, the objective was to acquire a way to speak by way of a special channel – e-mail or SMS – the place strict moderation wouldn’t happen.
These days, nearly all Neanderthals attempt to switch their Mammoths to much less policed, reputable chat platforms. Neanderthals select them as a result of they consider banning accounts there takes time. Moreover, sending varied hyperlinks over chat platforms is frequent observe slightly than suspicious habits. As a bonus, nearly all people is conversant in such purposes, so Neanderthals don’t have to elucidate 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
A few of the Neanderthals’ teams point out a special 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 reputable proprietor of an condominium, pretending to have an interest and ask for varied particulars, corresponding to further footage and what sort of neighbors the condominium has. The Neanderthals then take all this info and create their very own itemizing on one other web site, providing the condominium for hire. They reduce 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 indicate curiosity, and directs the Mammoth to pay a reservation payment by way of a hyperlink that, after all, truly factors to a phishing web site.
Due to 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 eventualities. This, mixed with the rip-off being marketed by Telekopye teams, leads us to consider 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 way of totally different manuals, teams, and extra supplies, we discovered an interview with a Telekopye administrator that was executed on the finish of 2020. This helped us get a novel 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 at all times be current. It’s a lot tougher [to scam] than it was once because of banning insurance policies on totally 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 obtained 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 understand they’ve been scammed. Apparently, everybody as of late is a spouse or a pal 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 lively way of life, does quite a lot of coaching, and he has solely 4 hours a day at dwelling.
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 continuously pay for hyperlinks, and somebody will continuously throw them. Whoever tries arduous in life will succeed.”. On high of that he says that if he feels sorry for Mammoth, he asks himself: “Why am I scamming them within the first place? Nicely… I solely steal from the wealthy (analysis word: Mammoths that in all probability 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’ve targeted on what we discovered about Neanderthals. Due to gaining access to each their inside communication and their data base, we’ve offered not solely descriptions of various rip-off eventualities, however primarily a novel perception into their modus operandi and mindset.
Now we have demonstrated how the admission course of for newcomers appears like and the way Telekopye aids Neanderthals of their day by day work. As well as, we’ve proven that they in all probability are experimenting with actual property scams as effectively.
On-line market scams are probably not going away. As we demonstrated in the first installment, we have been capable of uncover dozens of teams working Telekopye. That mentioned, by having our distinctive perception into the scammers’ operation, we consider loads will be discovered as a way to defend customers of such platforms from hurt.
