When the power grid goes dark from a cyberattack, your survival shifts from convenience to capability. Prioritize redundancy: harden communications with satellite messengers and ham radios, store offline backups of critical data, and secure analog maps. Stockpile fuel, water filtration, and off-grid power, such as solar and generators, to sustain operations. Harden your perimeter. Dark streets are an invitation for opportunists. Most importantly, establish a trusted intel network to track developing threats when official channels go silent.
