In this episode of Security Bite, I sit down with macOS reverse engineer Christopher Lopez (@L0Psec) and returning guest Kseniia Yamburkh (@osint_barbie) of MacPaw's Moonlock Lab to unpack ClickFix, the social engineering technique behind nearly half of all reported breaches in 2025. We get into who's actually falling victim, why it exploded so fast, how Mac malware is evolving in 2026, the current landscape, and more.

In this episode, I break down what I think is the most significant finding from Jamf's latest Security 360 report: trojan malware now accounting for over 50% of all Mac malware detections. This is up from roughly 17% just a year prior and beats out infostealers for the number one spot. But its not as simple as trojans are just getting popular...

It basically comes down to one malware family, Atomic Stealer (shocker), which is now simultaneously sitting at the top of both the trojan and infostealer categories. That dual classification is reshaping how we should think about the Mac threat landscape, because the old lines between malware categories I think are blurring.

In this episode, I sit down with Talal, one-half of the duo behind the Mysk security research X account and co-founder of Psylo, a privacy-focused iOS browser app that takes a fundamentally different approach to private browsing.

We get into why not all VPNs are created equal, how exactly websites are identifying you and tracking your moments across tabs, and how Psylo tackles all of this by giving every tab its own isolated silo, complete with a separate IP address, memory, storage, and more.

If you care about browser privacy on your iPhone, this one's worth a listen. Here's my conversation with Talal.

In this episode, I sit down with Jaron Bradley, author and Director at Jamf Threat Labs, to briefly explore the evolution of Apple security and threats over the last decade. In particular we discuss, the reason for infostealer's historic breakout as one of the most popular forms of malware and how AI is being used in the hands of attackers (and defenders too). Jaron also shares his 2026 threat outlook.
