Hacker forums are forums made primarily to discuss topics related to hacking. Often, these forums operate on the dark web because the dark web provides anonymity for the users visiting the website and the website itself. Topics in these forums range from general computer security news and tutorials for the distribution of malware and leaked information.
Anonymity tips, server hacking tools and password cracking techniques are discussed and shared on hacking forums. Stolen information is traded as well.
Also, some loosely connected hacking groups organise their activities through the forums and trade stolen information. Even specific exploits and hacking services are traded on the forums. Discussion channels within the dark web are used to coordinate attacks and share attack tools.
