The digital underworld of dark web forums represents a complex ecosystem where cybercriminals and security researchers converge. These platforms facilitate the exchange of illicit goods, services, and information while employing sophisticated systems to establish trust and conduct transactions. This article examines the structure, features, and activities of prominent dark web forums based on documented research and observations.

Introduction

Dark web forums have evolved into highly organized communities that operate outside conventional legal frameworks. These platforms serve as marketplaces for cybercrime tools, stolen data, and hacking services while implementing intricate reputation systems to facilitate trust among anonymous users. The forums vary in focus, membership requirements, and operational structures, with some specializing in particular types of cybercriminal activities while others offer broader platforms for various illicit exchanges. Understanding how these forums function provides insight into the mechanics of cybercrime operations and the challenges faced by cybersecurity professionals and law enforcement.

Prominent Dark Web Forums

BreachForums

BreachForums has emerged as one of the most prominent English-language dark web forums since its launch in November 2022. The platform hosts an extensive collection of data, containing over 15 billion records from more than 900 datasets and has attracted a membership exceeding 200,000 users. The forum accommodates a diverse user base, including high-profile actors with established reputations such as IntelBroker and Machine1337, alongside amateur hackers and cybersecurity researchers.

BreachForums facilitates discussions on a wide range of hacking topics while also serving as a publication and marketplace for data breaches, stealer logs, and hacking tools. The platform is accessible via both the surface web and TOR, though users must register to browse forums or view marketplace content. The forum employs an in-forum transaction credit point system to unlock content, with users able to purchase credits directly or earn them through active participation.

Despite its popularity, BreachForums has experienced significant disruptions since its inception. The majority of these disruptions have been temporary, but around April 15, 2025, the primary domain (.st) went offline. In the following weeks, considerable speculation arose regarding the forum's fate, with rumors suggesting notable members and moderators may have been arrested. Although a relaunch was announced on June 3, 2025, the forum was subsequently listed for sale, and as of recent reports, it continues to struggle with regaining its former reputation and user base.

XSS (formerly DaMaGeLaB)

XSS represents one of the oldest and most professionalized dark web forums, originally founded as DaMaGeLaB in 2004. The Russian-language platform was rebranded in 2018 to "xss," a name likely associated with cross-site scripting vulnerabilities. Currently, XSS maintains over 46,000 members and is generally perceived as a forum with highly structured rules and norms governing user behavior.

The platform has attracted career criminals, state-associated actors, and those seeking to buy or sell valuable illicit assets such as zero-day vulnerabilities. XSS was once a premier forum for ransomware-as-a-service (RaaS) collectives, hosting prominent groups including REvil, LockBit, and ALPHV. However, the forum implemented a significant policy change in 2021, banning all RaaS-associated activities, which remains in effect as of current reporting.

Exploitin

Exploitin has been actively utilized for cyber attacks and crimes since approximately 2012, gaining prominence following the closure of RaidForums in 2022. This Russian forum maintains a stricter membership policy compared to others, requiring new members to pay a fee and secure an invitation from an existing member. As of the latest report, Exploitin hosts 213,672 topics, 1,337,208 posts, and has 60,856 registered members.

The platform features regular sales of categorized cybercrime tools, database leaks, credit card information, malware, and even ransomware services. Its specialized focus and selective admission process have established it as a significant venue for certain types of cybercriminal activities.

Nulled and Altenen

Nulled has operated as a dark web forum since 2015, amassing an impressive 5,131,238 users and hosting 33 million posts. The platform attracts attention with offerings including fake identity documents, malware creation tools, and databases. In 2016, Nulled itself experienced a significant data breach when 9.45 GB of user information was disclosed.

Altenen, founded in 2008, maintains a substantial user base of 1.3 million members across 1,264,546 posts. This forum is particularly noted for its association with credit card fraud, as well as the production of fake identification documents and passports.

Cracked and LeakBase

Cracked represents a substantial dark web forum with 4.27 million users, focusing on cybersecurity topics including exploit development, zero-day exploits, and cybersecurity techniques. Despite its association with cybercriminal activities, the platform is not exclusively illegal and is reportedly utilized by cybersecurity experts and penetration testers for legitimate research purposes.

LeakBase emerged in 2023 as a specialized forum focused on database leaks, positioning itself as a competitor to other established forums in this space. The platform is free to join and offers opportunities for membership upgrades. Active database leaks are primarily shared by the staff team, though the forum also hosts user accounts, logs, various software, tools, and training materials. At the time of reporting, LeakBase contained 14,275 threads, 93,258 messages, and 45,946 members.

Other Notable Forums

Several other dark web forums operate with varying degrees of prominence and specialization:

DarkForums operates with many similarities to BreachForums but does not associate rank purchases with reputation scores.
Russian Market has gained popularity for trading stolen credentials and implements a reputation score correlated to the number of logs sold. The platform also maintains public refund histories, adding an additional dimension to perceived reliability.
Exposed emerged following the closure of Breached in March 2023, though concerns about potential FBI monitoring have affected user adoption.

Forum Systems and Trust Mechanisms

Dark web forums employ sophisticated systems to establish trust and facilitate transactions among anonymous users. These mechanisms are crucial for platforms where traditional legal recourse is unavailable and participants must rely on reputational factors to assess reliability.

Credit and Point Systems

Many dark web forums implement internal currencies or point systems to facilitate transactions. BreachForums, for example, uses an in-forum transaction credit point system where users can either purchase credits directly or earn them through active participation. This system allows users to unlock premium content and access marketplace features. Similarly, XSS and the Breach forum utilize credit systems for internal transactions, creating an economy within the forum ecosystem.

Reputation Scoring

Reputation scores represent one of the most critical trust mechanisms in dark web forums. These scores typically reflect a user's history of successful transactions, reliability, and contributions to the community. The methods for obtaining reputation scores vary significantly across platforms:

BreachForums and similar forums often award "points" from fellow users when sharing free content. Users can also gain points through successful transactions or by purchasing a "rank," which grants a fixed reputation score.
DarkForums operates similarly to BreachForums but does not associate rank purchases with reputation scores.
Russian Market implements a reputation score directly correlated to the number of logs sold, while also maintaining public refund histories as an additional trust indicator.
More exclusive forums like Exploit, Ramp, and xss typically do not allow purchased reputation. Instead, users must build their reputation through meaningful participation, successful transactions, or by providing high-quality insights and feedback that are valued by peers.

Reputation scores significantly influence a user's ability to conduct business on these platforms. Users with poor reputations often face difficulties initiating transactions or may even be barred from joining certain forums. Those with low scores or limited platform history might be trusted only with low-stakes transactions but typically encounter barriers when attempting exchanges involving larger sums.

Membership Requirements

Dark web forums employ varying membership requirements that reflect their level of exclusivity and security considerations:

Some forums like BreachForums and XSS offer free account creation, making them more accessible but potentially more vulnerable to infiltration.
Others like Exploitin implement stricter policies, requiring new members to pay a fee and secure an invitation from an existing member. This selective admission process helps maintain community quality and security.
Russian Market has emerged as an increasingly popular choice for trading stolen credentials, with its reputation system and public refund history contributing to its perceived reliability.
Xss, as one of the oldest forums, maintains closed membership policies and is generally perceived as highly professionalized, with established rules and norms governing user behavior.

Forum Activities and Specializations

Dark web forums facilitate a wide range of cybercriminal activities and specialized services, with each platform often developing its particular focus and expertise.

Database Leaks and Data Trading

Database leaks represent one of the most common commodities traded on dark web forums. BreachForums, for instance, has been used to advertise numerous prominent data leaks related to government entities, healthcare organizations, and international non-governmental organizations (NGOs). The forum hosts an extensive collection of compromised data, with over 15 billion records from more than 900 datasets.

LeakBase has carved out a specialized niche in database leak trading, emerging in 2023 specifically to challenge established forums in this space. The platform focuses primarily on active database leaks, with staff members regularly sharing new compromised data. Beyond database leaks, these forums typically host additional offerings including user accounts, logs, various software, and tools.

Cybercrime Tools and Services

Dark web forums serve as marketplaces for an extensive array of cybercrime tools and services:

Exploitin features regular sales of categorized cybercrime tools, including specialized software for various illicit purposes.
