Hackercool Magazine - Sep 2025

In this issue

Welcome to this month’s issue of Hackercool Magazine, where we dive headfirst into the evolving—and often unsettling—landscape of digital defense and offense. As we step closer to 2026, the line between attacker and defender continues to blur, powered by advancements in AI, automation, and adaptive threat strategies. In this issue, we start with a look inside the future of Red teaming against AI-powered defenses, unpacking the next generation of tactics, techniques, and tools security professionals must master. The battlefield is changing, and human creativity remains the ultimate exploit. Our vulnerability coverage this month is extensive and essential. From the Chrome zero-day (CVE-2025-10585) already under active exploitation, to critical exposures in Gladinet's Triofox (CVE-2025-11371) and Cisco ASA firewalls (CVE-2025-20333), we break down what these flaws mean for your environment—and how to respond before attackers do. For defenders, we feature a deep dive into open source tools every Blue Teamer should know about in our article "Open-source tools every Blue Team should know". On the privacy front, our "Anonymous Zone" explores Tails 7.0, the latest release of the go-to OS for anonymity, while our "Mobile Security" section exposes the stealth and sophistication behind "Klopatra", an Android trojan designed to drain bank accounts and hijack entire devices. We also review the latest updates in recently released Kali Linux 2025.3, keeping penetration testers and researchers informed of the newest features and tools that keep the community sharp. As always, cybersecurity is not just about tools—it’s about awareness, adaptability, and constant learning. Whether you’re red, blue, or somewhere in between, this issue aims to keep you ahead of the next exploit.
