We prove what an attacker can really do to you continuously, and we hand you the detection information you need to improve.

We scanned thousands of hosts for CVE-2026-48710 and found something important: being behind a reverse proxy, CDN, or Cloudflare is not always enough protection. In some setups, X-Forwarded-Host can still be used as a bypass. (1/2)

AI agents mimic human pentesting logic at a scale scanners can't match, looking deceptively manual. Detecting agentic traffic through response patterns and riddles is the first step in defense. #AIpentesting #securityassessment #vulnerabilityassessment
