DNS Hijacking Is Cheap and Devastating

Attackers compromise DNS records to reroute traffic, steal credentials, or impersonate services. Few teams monitor DNS changes in real-time — even though they determine where users go.

Typosquatting Exploits User Error

Fake domains mimic real ones — google.com, micorsoft.net. When DNS isn't filtered or validated, users land on malicious sites without knowing it. Detection needs context, not just lists.

DNS Logs Are Gold for Threat Intel

Outbound DNS requests show what systems are trying to reach — even when encryption hides payloads. Filtering and analyzing DNS traffic can reveal malware beacons and rogue tools.

Legacy DNS Configs Create Blind Spots

Old, unused records remain active. Subdomain takeovers and dangling entries expose apps unintentionally. DNS hygiene is rarely part of security checklists — but should be.

DNS Tunneling Bypasses Firewalls Silently

Attackers encode payloads into DNS requests. These pass through firewalls and proxies unnoticed. DNS becomes both a signal and a weapon.

Secure DNS (DoH/DoT) Isn’t the Whole Solution

Encrypted DNS protects privacy — but breaks visibility. Without careful handling, security teams lose insight into traffic patterns. Balance privacy with observability.
