The Signal: The Cyber-Bazaar Survival Guide — A Visual Guide to OT Hacks, Rogue TV Boxes, Legacy Tech Debt, and Workplace Tech

How can hackers thousands of miles away turn 115+ supermarket freezers into +50°C (122°F) heaters overnight? Why did Google permanently ban a hardware manufacturer after uncovering a factory-burned backdoor inside 1.3 million Android TV boxes? And why does pasting a column of invoice due dates into Excel suddenly make it look like your company owes $46,329 for a box of printer paper?

Guided by a sharp-eyed cyber-chameleon across three sectors (Threat Radar, Gadget Mastery, and The Archives), you will learn how physical building hardware, office spreadsheets, and legacy software actually work under the hood.
