The scammers who scam scammers on cybercrime forums: Part 3

In the first chapter of this series, we provided an overview of the hidden sub-economy of scammers who scam scammers, and in the second we examined the wide variety of scams and tricks within it.

The third chapter is a little different. It covers a specific scam we uncovered during our research, which we highlight because of its scale, levels of coordination, and apparent success.

The curious case of twenty fake marketplaces

During our research into Genesis Market, we found a clearnet site (genesismarket[.]org) that looked nothing like the genuine Genesis Market site but appeared prominently in search engine results.

We quickly determined that the site didn’t seem to be connected to the genuine Genesis Market. For one thing, the site demands a $100 USD deposit, whereas the real Genesis is invitation-only.

The site asks users to pay in Bitcoin or Monero:

This, and a few other elements (such as the ‘lost password’ button not redirecting anywhere, and some falsified ‘forum posts’) led us to assume it was a crude, low-effort, one-off scam, designed to take advantage of inexperienced researchers, would-be threat actors, and the generally curious.

But three things piqued our curiosity.

The first was that the onion link on the homepage doesn’t link to an onion site at all, but to genesismarket[.]org/benumbiernqlud55izbw4mdubush4zhzpg4rw3c2j6ew3ggpzbb7gdqd[.]onion. Benumb is a carding site, and we wondered if someone from that marketplace was running the scam and had made a mistake with the link.

The second thing was that the Copy address button on the deposit page triggers some JavaScript, which copies a different Bitcoin address to the clipboard:

And the third was that someone had actively advertised this site on Reddit, which suggested the scam might be more coordinated than we first thought:

We visited the ‘Benumb’ link and found a site set up in exactly the same way, with the same demand for $100 (albeit with different Bitcoin and Monero addresses):

And when we looked at the credit card numbers on the homepage, we discovered that they were identical to the ones listed on the fake Genesis site.

Figure 9: The credit card numbers and details on the fake Benumb homepage…

Figure 10: …which are exactly the same as those on the fake Genesis site

We started querying search engines for portions of the text, the credit card details, and the cryptocurrency addresses, to find other sites created by the same scammer.

All in all we found twenty sites, registered between August 2021 and June 2022, which we assess with high confidence are operated by the same individual or group. Virtually all of them imitate existing or defunct criminal marketplaces (including multiple scam versions of Genesis, Benumb, UniCC, and Pois0n), ask for an activation deposit of $100, and have a similar look and feel. Some employ the same clipboard substitution quirk, and some don’t. We also observed a few other minor differences, like background color or slight modifications to the spiel.

Along the way, we found evidence that the scammer was advertising other sites on Reddit:

We did find one anomaly – a site called ‘Cashout Guide’, which claims to teach users carding and fraud (for a fee, naturally) – which nonetheless has a similar appearance to the scam marketplaces:

Figure 17: Available tiers on the Cashout Guide site

Of the twenty sites we found, thirteen are no longer active. Most are clearnet sites, although we discovered three onion sites (and one clearnet site masquerading as an onion site).

Here’s a full list, along with the associated Bitcoin addresses and registration information (where available):

Table 1: The sites we discovered

When we collated information from all the Bitcoin addresses (by design, the balances of Monero addresses are hidden), we found that this scam network has been lucrative. Together, those addresses have received over $132,000 – and most of it has been withdrawn, leaving a total balance of only $1,633.34.

We can’t say for certain whether all the inputs to those addresses are related to the scam (i.e., we don’t know if the scammer has used them for other business), and in a few cases, the timelines didn’t add up (a few addresses made their first transaction before the associated site(s) were registered, so some inputs may have been unrelated to the scam). But even taking those examples out, there was still $87,676 going into those wallets.

One big question remained: who was behind the scam?

We found something we thought might be a clue: on some sites, the footer contains a link to a website called darknet[.]markets (there appear to be a few versions of this site with very similar content, including darknetmarket[.]org and dark[.]markets).

Figure 18: A link to darknet[.]markets on the scam site unic[.]cards

These sites are indexes of dark web criminal marketplaces, for visitors interested in drugs sales, carding, and cryptocurrency exchanges. Not only do they look similar to the scam marketplaces (and with similar hosting/registration details), they also list several of the fake marketplaces we discovered.

Figure 19: The ‘carding’ section on dark[.]markets

Most of the activation notices on the scam marketplaces mention a carding forum on the criminal marketplace Dread (also known as Café Dread). We searched the names of the index sites on Dread, and found a post by a user called waltcranston (the username is likely inspired by the television series Breaking Bad), who claimed to have created them:

We also found at least one Dread user who seemed to fall for one of the scams:

We dug further into the index sites, and found waltcranston listed prominently in the ‘Drug Markets’ section:

waltcranston is a self-proclaimed methamphetamine dealer on both Dread and other marketplaces such as Alphabay. By their own admission they’re based in the US:

Their website appears to use a similar template to the scam marketplaces, and the clearnet version has similar hosting and registration details:

We also found that one of the fake forum posts on at least one of the scam marketplaces was written by a waltcranston:

waltcranston uses both Bitcoin and Monero, as shown in this post:

Figure 26: In a post relating to their methamphetamine business, waltcranston confirms they use both Bitcoin and Monero

And several of waltcranston’s posts indicate a familiarity with criminal marketplaces and an open-minded attitude towards phishing and scamming, particularly when it comes to imitating specific marketplaces:

A Dread user had come to the same conclusion as us, publicly posting this accusation:

Figure 31: A Dread user calls out waltcranston for running some of the scam marketplaces we discovered

waltcranston did not confirm or deny the allegation in his responses, although other Dread users chipped in:

Figure 32: Some Dread users condemned scammers

In the above conversation, the accuser suggests a possible motivation for waltcranston running these scamming sites – retirement from dealing methamphetamine.

Other Dread users were more apathetic about the situation:

We should point out here that most of this evidence is circumstantial, and we didn’t find any discrete identifiers which link waltcranston to the fake marketplaces.
