This episode digs into a CISA deadline for a critical Splunk vulnerability that's already being exploited in the wild, a North Korean supply chain attack that poisoned over 140 npm packages, and how a junior hacker used legitimate tools like Tailscale to maintain persistence after losing his primary command server. Adrian breaks down six stories that show how attackers are leveraging trust, timing, and creative tradecraft to stay ahead.
