IP address to organization name map
Mapping Internet number resources from IP addresses to organizations is straightforward using whois or RDAP, but listing all resources held by a given organization is far more challenging. This post explores a simpler, data-driven approach using RIR extended statistics and reg-id identifiers.

From spoofing to tunnelling: New Red Team networking techniques for initial access and evasion
Guest Post: In modern network architecture, we often assume that perimeter defences are robust enough to keep internal traffic secure. However, vulnerabilities inherent in the trust mechanisms of fundamental network protocols reveal that unencrypted tunnels can become fatal backdoors in enterprise intranets.
