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

What happens when an AI pentester gets hijacked during recon? Planted pull requests or deceptive code can manipulate an agent's reasoning engine before it ever runs an exploit. Just knowing these dangers isn't enough. #AIpentesting #securityassessment #vulnerabilityassessment
