This week we are joined by Marcelle Lee, cybersecurity consultant and researcher, discussing "CTI tradecraft: Investigating a mobile scareware campaign." She details how a routine click on a Google News story led to a mobile scareware pop-up—and a deeper investigation into a broader campaign.
Using free tools like Censys, URLScan, VirusTotal, and CyberChef, she pivoted from two domains to uncover more than 100 related domains, shared infrastructure, and links to questionable antivirus apps in the Google Play Store. The findings are mapped to the MITRE ATT&CK framework, showing how freely available resources can power meaningful, actionable threat intelligence. Research Saturday

In this episode of Threat Vector, host David Moulton speaks with LeeAnne Pelzer, Senior Consulting Director, and Brandon Hogle, Consulting Director, both with Palo Alto Networks Unit 42.

Zero Trust is the foundation of modern cybersecurity, but turning principles into measurable outcomes remains a challenge for many enterprises. Pelzer and Hogle share how Unit 42’s Zero Trust Advisory helps organizations assess their cybersecurity maturity, identify visibility gaps, and create tailored roadmaps that connect security architecture with business outcomes.The conversation dives into the common pitfalls that derail Zero Trust, including visibility gaps, operational complexity, and misalignment, and explores how to overcome them with clarity, collaboration, and continuous verification. For security leaders driving transformation, this episode offers a pragmatic look at how to cut through complexity and make Zero Trust achievable.
