UK and Israel Prepare for 'Black Sky' Cyberattack Blackout Scenarios
Britain and Israel are preparing for 'Black Sky' cyberattack scenarios that could paralyze national power grids. Investigations reveal emergency protocols to maintain vital radio broadcasts and public safety communications during prolonged blackouts.
Britain is preparing for a "Black Sky" emergency scenario where a catastrophic cyberattack could paralyze the national power grid, communications, water supply, and leave millions of citizens isolated. A BBC investigation reveals a secret contingency plan designed to ensure that radio broadcasts remain operational even under total blackout conditions.
The growing threat of targeted cyberattacks against critical infrastructure across Europe has raised alarms. Recent incidents include cyberattacks on supermarket refrigeration systems in several European countries and blood bank cooling centers in France, forcing emergency relocations of blood supplies. The UK National Cyber Security Centre (NCSC) recently blamed Russia for a December 2025 cyberattack targeting Poland's power grid, which nearly left half a million people without electricity during winter.
AI Threats and Past Disasters
Richard Horne, head of the UK National Cyber Security Centre, warned that AI-driven ransomware attacks targeting critical national infrastructure are expected by 2028. This technology will allow attackers to exploit security vulnerabilities on an unprecedented scale. A historical precedent occurred in December 2015, when severe flooding in Lancaster, north-west England, left 61,500 residents without power. Within hours, water supplies failed, trains halted, and ATMs stopped working, turning the city into a scene resembling a zombie movie.
To counter such crises, the BBC has prepared an emergency protocol involving a secure studio operated by around 100 staff members. Equipped with food, water, and fuel generators, the facility can operate autonomously for at least 72 hours, broadcasting pre-approved government instructions and survival guides via independent radio transmitters backed by up to 40,000 liters of diesel.
Preparedness in Israel
Israel is also bracing for similar grid-failure scenarios. According to National Emergency Management Authority projections, severe infrastructure damage could leave approximately 60% of households without electricity for up to 72 hours, alongside disruptions in water and telecommunications. The Home Front Command advises citizens to stock battery-powered radios, emergency water, and non-perishable food, while the Ministry of Communications strengthens backup systems at vital telecommunication sites.
