Introduction
The surge in emerging threat actors directly correlates with the rapid escalation of victim counts and stolen financial resources. Simultaneously, this growth has spurred the proliferation of specialized supply storefronts across social media platforms, dark web channels, and various smaller niche marketplaces. Security teams today face evolving challenges, requiring them to continuously refine monitoring channels, adjust operational strategies, and foster cross-functional internal collaboration to capture actionable intelligence.
With fraud damages anticipated to approach hundreds of billions of USD, security teams must navigate numerous non-compliant channels while ingesting and processing diverse data formats—such as documents, imagery, video, and unformatted text—linked to organizational assets. The recent introduction of a new Fraud framework by the MITRE organization underscores the critical need to combat fraud and highlights the significant danger these threat actors pose to all organizations. The MITRE organization has been taking a positive step towards standardizing the fight against fraud, while helping organizations target the relevant directions to look at.
These marketplaces supply a range of services in need for the novice fraudster, encompassing server infrastructure, targeted lists, and even support for money laundering facilitated through compromised accounts across various platforms. As larger, well-known marketplaces have been dismantled, smaller, specialized shops are experiencing heightened activity from buyers seeking to engage in fraudulent endeavors.
This blog post undertakes an exploration of these marketplaces and their operational modalities, illuminating the contemporary fraud economy and underscoring the enduring critical nature of robust detection and prevention initiatives.
Fraud-as-a-Service (FaaS)
Fraud is broadly defined as an intentional, dishonest act or misrepresentation of material facts, calculated to deceive others in order to secure an unfair or unlawful gain. Consequently, the Fraud-as-a-Service (FaaS) model encompasses various vendors and digital storefronts that facilitate such activities by providing new tools, instructional guides, and ancillary services for fraudsters.
Online shops and marketplaces, such as Xleet, Blackpass, Infodig and Styx, provide a venue for contemporary fraudsters to acquire the necessary resources for whichever scheme they intend to execute. Users are able to purchase active accounts for online platforms, including major financial institutions, online dating services, and even AI platforms. In addition different offerings may include stolen PII, synthetic identity generator, and ready to use online infrastructure.
To satisfy shifting market demands, threat actors—alongside malware developers and marketplace administrators—continuously refine their products to optimize future monetization. Novice fraudsters often begin their journey by seeking instructional manuals on various forums or platforms like Styx. Once a strategy is established, they leverage diverse online shops and marketplaces to acquire the necessary infrastructure and credentials. These same venues frequently provide stolen personal or business data, which criminals then exploit during the monetization phase. A common tactic involves business email compromise (BEC) schemes designed to manipulate customers into transferring funds directly to accounts controlled by the fraudster.

As companies attempt to protect themselves from being taken advantage of by these fraudsters, they could gather troves of important intelligence about how the malicious actors think, and more importantly gain operational information about breaking fraud networks and protecting their ecosystems. Companies may utilize the available or purchased information into operational decisions, reducing the number of incidents, or at least hinder the fraudster’s attempts.
MITRE Fraud Fighting Framework (F3)
Introduced in early 2026, the MITRE Fraud Fighting Framework (MITRE F3) is designed to help organizations recognize adversarial TTPs, and could help security teams prioritize relevant sources for monitoring through prioritization of attack vectors or vulnerabilities. Due to the large amount of available sources, such a framework could indeed help organizations create the best strategy.
While the framework's structure mirrors traditional MITRE matrices, MITRE F3 expands into domains bridging cybersecurity and financial crime, specifically addressing the monetization stage. Although it introduces a novel perspective on fraud analysis, it does not sufficiently address the necessity of enhanced collaboration between an organization's internal departments.
To obtain meaningful environmental insights, security, fraud, and financial crime teams must maintain constant surveillance of marketplaces and similar forums. Monitoring marketplaces for asset mentions is critical for early detection of threats and new trends targeting new victims.
Key marketplaces and trends
Like other cybercrime-focused shops and forums, our monitored marketplaces also handle external threats targeting their clientele; some even use mirror sites. Similarly to other underground marketplaces, the key players must navigate themselves in an ever changing shattered environment where new marketplaces operate along alternative shopping methods through Telegram and P2P options.
When examining the MITRE framework, we can immediately see many techniques in common–mostly account takeover (ATO) techniques. Nevertheless, as seen in the different stocks and sellers, the offerings changed with time according to market demands.
There are some notable differences between Styx and the rest of the reported marketplaces, however. Styx operates by offering sellers more space for promoting their own personal shops, available mostly through Telegram.

⠀
Styx also aims to cultivate a specialized community through their "freemium" model, where premium, high-value content is reserved for users willing to pay significant fees.

⠀
While some of the free manuals have been posted through different cybercrime forums before, they show not only a real attempt by the Styx admins to generate additional income, but also sell ad space for different sellers working outside of the marketplace. These monetization techniques indicate the admins are probably well aware they have many competitors, as they attempt to provide a different shopping experience for their users.
Resource development: Infrastructure
Infrastructure for cybercrime operations has been sold for a long time, offering adversaries illegal access to active domains, cpanels, and more.
One of the leading marketplaces for such items is Xleet, first observed in 2022, which has quickly become a source for large collections of stolen credentials spanning multiple platforms. Distinguishing itself from other monitored marketplaces, Xleet is transparent about its offerings, frequently including evidence like screenshots or even email proof sent to the compromised account's email address.

Access to SMTP servers could help fraudsters reach larger audiences and evade different email protection and filtering services, thus improving success rate for different schemes. Xleet also offers alleged access to protected networks through Cpanel, web shells, SSH, and RDP connections, as well as VoIP access through their accounts:

BlackPass is another marketplace offering RDP credentials, as well as proxy services used by malicious actors for veiling their location or, as mentioned above, bypassing different restrictions on their IP addresses.
Blackpass, initially named 'Paysell,' emerged as one of the first known online marketplaces dedicated to selling compromised accounts. Estimates suggest this platform has facilitated the sale of hundreds of millions of accounts. Legal documents indicate the marketplace is controlled by Russian cybercriminals, a detail consistent with its product focus: items exclusively targeting Western countries, particularly the US.

All of these vulnerable environments could be part of a bigger scheme run by fraudsters, leading to other techniques being executed like a new vendor set up.
Another marketplace, Infodig, would offer different phone infrastructure in the past as mentioned in one of their opening posts on a cybercrime forum. Foreign or stolen numbers could be used for receiving or intercepting OTP messages, forging IT calls to employees, or self registering new accounts for other services.
Infodig has recently revamped some services offered, including the phone infrastructure, having been removed completely around the end of 2025 during an update the marketplace went through.

Styx also offers many options for fraudsters looking for ready to use infrastructure including eSIMs, VoIP services, and compromised VPN accounts. Localized SIM cards could be used by fraudsters for many reasons such as account creation but more importantly as a way to strengthen claims when confronting modern anti-fraud solutions, thus improving scam success rates.

⠀
The same marketplaces offer additional stolen, forged, and even active company documents for sale including incorporation forms, US tax forms, and other various products connected to shelf companies and stolen PII. These documents allow threat actors to generate troves of mule accounts, shelf corporations, and even combine them into money laundering networks.
Acquiring access
Stolen, self-registered (self-reg), or user-sold accounts are high-demand assets in underground markets. By acquiring pre-existing accounts that have already circumvented anti-fraud protections, threat actors can rapidly deploy them for various criminal operations.
These platforms provide access to a wide range of services, from financial institutions and streaming providers to dating sites and AI-driven website builders. Novice fraudsters often utilize these resources to secure quick profits or to stockpile accounts for future resale.
For example, Blackpass features an extensive account inventory that includes regional banks, neo-banks, and major corporations. Pricing within these markets is fluid; however, self-reg accounts typically represent the most expensive tier due to the significant labor required for their initial setup.

Xleet provides an extensive accounts division that covers a broad spectrum of common targets, including gaming, streaming, and dating service profiles. These specific credentials serve as high-value assets for executing various "pig butchering" fraud operations. Furthermore, a notable emerging trend within this marketplace is the significant surge in available credentials for AI platforms, especially those focused on accelerated website creation.

Styx holds the usual stock including stolen or self-reg accounts for a large variety of services, including financial institutions, social media accounts, streaming services, and casinos or other gambling sites.

The inventory at Infodig is categorized into several distinct sections, featuring stealer logs alongside stolen Financial Information and Personal Identifiable Information (PII), such as Social Security numbers. Their accounts division has recently been going through some technical or supply issues and there are no current accounts available. However the marketplace has revamped their target list section into a new ULP (URL:LOGIN:PASS), offering a new targeted option for large scale ATO operations.

Monetization
Styx has gained notoriety for its support of various "cashout" operations, which are prominently featured in numerous service advertisements throughout the platform.
By functioning as a hybrid of a marketplace and a forum, Styx provides a unique platform where merchants can offer specialized cashout services that exploit financial institutions across different payment rails. These merchants utilize various business accounts to assist fraudsters in laundering illicit funds through established methods, including payroll schemes, ACH transfers, and refund scams targeting multiple banks and geographic regions.

⠀
Beyond explicit solicitations for these services, marketplaces provide a variety of other products that are frequently exploited for money laundering. The exploitation of online gambling platforms remains a prevalent tactic for fraudsters, particularly as new regulations across the US lead to more states and companies entering the market. By acquiring stolen or synthetic PII, malicious actors can establish new gambling accounts to facilitate the laundering of illicit funds through techniques like chip dumping and minimal gameplay.
Conclusion
The fraud economy is changing at a fast pace with new techniques and players entering the field every day. By examining the different marketplaces portrayed in this blog post, we can see that they all react and appeal to different market needs.
The change seen through available items across shops are a clear indication of this, as marketplaces pivot towards a larger crowd–one lacking the deep technical knowledge of the earlier fraudsters and carders. The different marketplaces allow every new fraudster to purchase their entire infrastructure for the fraud kill chain, from target lists, servers, and even support for laundering illegal income. Other online services include rapid AI creation of phishing threats, or other forms of abuse of legitimate service through stolen credentials. Marketplaces are not solely made for direct use and other threat actors view them as a major supplier for their shops as well, due to their fixed prices for items with prices which could easily be inflated through their personal shops as seen below:

As fraud communities and groups become increasingly fragmented, the industry continues to splinter into smaller shops. These new, smaller marketplaces often require an invitation or administrator approval to join, a tactic designed to impede investigations and extend the lifespan of their fraudulent products. This shift to smaller shops also benefits merchants, allowing them to keep 100% of their profits instead of sharing them with marketplace administrators. Targeted companies should continue to monitor the marketplaces as they continue to function as an important link in the fraud supply chain. Threat actors are very aware and understand a major part of every business is the profit, therefore financial crime services and associated accounts are continuing to evolve.
Nevertheless, underground marketplaces will continue to operate as an important part of the cybercrime economic system. Smaller merchants may use these larger stores as suppliers for their smaller shops, as second income or even double or triple their income by selling the same stock in multiple locations. However companies should not only be aware of these underground ‘malls’, and regularly monitor them for any suspicious findings, but take a more proactive approach. The evolving nature of fraud demands a stronger reaction from organizations as well as cooperation from security, financial crime, and compliance teams for proactive measures against these threats.
Targeted companies, especially financial institutions or gambling providers, should actively investigate stolen accounts and gather vital intelligence for protecting themselves in the future, making it more difficult for threat actors to abuse their payment rails, brands, and customers.
What organizations should do
To safeguard both their infrastructure and clients, security teams must move beyond monitoring disparate data streams and actively align with internal fraud and financial crime units to cultivate actionable intelligence. Because illicit merchants rely on marketing their offerings, security analysts should actively communicate with threat actors, purchase account samples, as well as analyze images or videos to map threat actor networks, verify operational legitimacy, and finally deploy targeted security countermeasures. Threat actors are threatening organizations with more than just data exfiltration, with compliance or financial crime requirements, companies become more vulnerable to newer forms of threats, not commonly associated with security teams, but initiating through cybercrime sources.
By proactively identifying leaked assets, correlating them to their own environments, and responding quickly through credential resets, and fraud monitoring, organizations can significantly reduce both financial losses and downstream risks such as ATO, and money laundering.
