This rule detects network connections to known exploit sales platforms such as exploit.in, 0day.today, and leakbase. It specifically looks for HTTP traffic where the host header matches one of these domains, indicating potential access to marketplaces for exploits and zero-day vulnerabilities.
This rule detects outbound TCP connections to port 9050, which is commonly used by Tor proxies. The rule specifically looks for the initial SYN packet (flags:S) of a TCP connection from the home network to any destination on port 9050. This activity is flagged as a policy violation, indicating the use of a Tor proxy for accessing closed source resources.
This rule detects attempts to access known online platforms used for purchasing stolen data, such as 'leakbase', 'breachforums', and 'raidforums'. It specifically looks for these keywords in the HTTP host header during client-to-server HTTP traffic.
This rule detects access to known exploit kit purchase or dark web marketplace sites by inspecting HTTP host headers for specific domain patterns. The rule triggers an alert if a client on the home network attempts to connect to any of the listed domains, which are associated with exploit kit sales or underground forums.
