Palo Alto Networks uncovers advanced threat campaigns using DNS tunneling for tracking and scanning activities.

Unit 42 reports attackers track user interactions with CDN-hosted content and measure phishing success through DNS requests.

Threat actors exploit DNS tunneling to probe network infrastructure and launch reflection attacks by finding open resolvers.

To mitigate these cybersecurity risks, organizations should deploy software to detect abnormal DNS traffic and update systems regularly.

Experts, including Elizabeth Montalbano, highlight the importance of vigilance against suspicious links to prevent such infiltrations.
