security profitable added: Sunday February 2026 17:05

A security software solution that monitors DNS traffic in real-time, detects anomalous patterns indicative of ClickFix-style attacks (like unusual nslookup usage), and automatically blocks suspicious DNS queries, preventing malware staging and data exfiltration. It integrates with existing security infrastructure to provide an additional layer of defense against social engineering attacks.
