Please enjoy this encore of Career Notes.

Adam Marrè, CISO from Arctic Wolf, sits down to share his story of rising through the ranks. After 9/11 he decided he wanted to make a difference in the world, and so he chose to go into the FBI. There he learned the skills that got him to where he is today. In his time at the FBI, he was able to do what he loved, which was working with computers while gaining more knowledge on cybersecurity, and he became computer forensic certified. Ultimately, he needed a change in the end and decided to leave the FBI. He was able to learn the leadership skills he needed to move past that career path and follow a new dream. He is now able to share his passion with the world and help people understand security to help protect themselves as well as helping people finding success in their careers and in their lives. We thank Adam for sharing his story.

This week, we are joined by Juliana Testa, Senior Security Engineer from 7AI, sharing their work on "Quish Splash - When the QR Code Is the Weapon: A Multi-Wave Phishing Campaign That Slipped Past Every Filter." A large-scale “quishing” campaign used QR codes embedded in image attachments to hide phishing URLs, allowing 28 out of 33 emails to bypass SPF, DKIM, DMARC, and Microsoft Defender and land directly in inboxes.

Each recipient received a unique QR code and tracking ID, defeating traditional detection methods and enabling attackers to scale the campaign to over 1.6 million emails across multiple organizations while shifting execution to less-secure mobile devices. The attack was ultimately uncovered through AI-driven alerting combined with human analysis and threat hunting, highlighting a major blind spot in email security and the need for QR code inspection, mobile protections, and tighter auto-reply controls.

The research and executive brief can be found here:
