Hacker Forums

Hackers use forums as message boards to post messages via conversation threads that encompass hacking tools, tutorials, and malicious source code. The Artificial Intelligence Lab at the University of Arizona collected several major Forums in three different languages from hacker community ecosystem in order to facilitate the research in this area of cybersecurity. This collection covers emerging topics such as social engineering, AI bots, and ransomware that can facilitate the cutting edge research in analyzing hacker community. It contains useful data about forums’ posts including thread title, authors, joining date of authors, post date, and the post textual content. The forums in each language category were selected based on criteria such as the number of attachment, number of posts and number of users. The popularity of forums in hacker community combined with the rich metadata such as post date (included in ReadMe.txt), makes forum a unique data source for conducting cybersecurity research on assets used by hackers, identifying prolific threat actors, and discovering emerging threats.


English is the dominant language in hacker forums. English forums contributes to a large portion of knowledge and tool exchanges in hacker community and therefore are suitable to obtain large volumes of information about English hacker community which is not limited to English-speaking countries The topics include breached data, mobile malware, cryptocurrencies, login dumps, code for AI bots, etc.

  •   CrackingArena Forum with 44,927 posts and 11,977 active users is one of the largest forums existing in 2018.The platform has a dedicated section to hacking tools and tutorials, called "hacking zone". This section contains content-rich threads with high user participation which makes this forum conducive to cybersecurity research on the interaction patterns among cybercriminals. The variety of covered topics in the forum ranges from social engineering, cracking tool and tutorials, to exploits which makes this forum a viable source for pinpointing the characteristics of newly emerged hacker assets. The posts in this forum date from 4/8/2013 – 2/24/2018.

From cybersecurity research perspective, it is crucial to analyze the data sources in other languages to obtain a global insight about cyber threats across platforms since different geographical regions differ in tools, focus, and malicious intentions. Russian is the second largest language in hacker forums and compared to English forums they are more focused on exchanging highly-specialized hacking tools.  

  • Antichat Forum is one of the largest Russian forums with 233,480 collected posts. As a large-scale communication platform, it gained significant reputation for a data breach that revealed passwords of several thousands of its users. The topics in this forum cover vulnerabilities, anonymity, and security issues reported by administrators. One of the unique characteristics of this forum is having specific sections for web masters and system administrators. These sections contain highly specialized discussion that can answer fine-grained research questions about the threat landscape in hacker community from the view point of experts. Posts date from 3/6/2002 – 3/27/2018.
    • Suggested analytics: Identification of non-English cyber threats in Russian hacker community via applying multilingual classifiers
    • Suggested techniques: Advanced classification techniques such as deep learning
    • Suggested tools: TensorFlow, PyTorch, and Theano
