The Signal: Master Navigator's Briefing — A Visual Guide to Supply-Chain Hijacks, Bug Bounties, Self-Healing Tech, and Workplace Mastery

How did a friendly live video call with a fake HR recruiter—followed by a poisoned pyenv coding test from a fake "CEO"—spark the record $6.34 billion Binance heist? Why isn't installing a vendor's clean patch enough after a 12-hour supply-chain hijack across 2,946 Linux servers? And how did a 1-millisecond vibration when NASA's Mars Polar Lander unfolded its legs trick the onboard computer into shutting off its rocket engines 40 meters in mid-air?

The Signal: Master Navigator's Briefing (Volume 4 of The Signal Visual Tech Guides) pairs 13 full-color sci-fi command-deck panels with a plain-English workplace manual written for everyday professionals—no tech degree required. Guided from the bridge by a deep-space octopus navigator, each chapter connects high-stakes cybersecurity disclosures, engineering lessons, and 1-second office shortcuts.

Inside Volume 4, you'll discover how to:
