APT 41’s VPN Exploits & The Great Firewall’s Leaky Secrets

In this episode of Breaking Badness, we dive into two major cybersecurity stories: the exploitation of a VPN vulnerability by Chinese APT 41 and the newly discovered “Wall Bleed” flaw in the Great Firewall of China. APT 41 has been using a critical VPN vulnerability to infiltrate operational technology (OT) organizations, targeting industries like aerospace and defense. Meanwhile, researchers have uncovered a flaw in China's DNS injection system, which inadvertently leaks internal data—an ironic twist for a government known for its strict internet censorship. Join us as we break down these exploits, their impact on cybersecurity, and what they reveal about modern cyber espionage. We also discuss best practices for securing VPNs, firewall vulnerabilities, and the ethical implications of studying censorship technologies.
