Online criminal forums, both on the public internet and on the “dark web” of Tor .onion sites, are a rich resource for threat intelligence researchers. The Sophos Counter Threat Unit (CTU) has a team of darkweb researchers collecting intelligence and interacting with darkweb forums, but combing through these posts is a time-consuming and resource-intensive task, and it’s always possible that things are missed.
