Despite Russia warnings, Western critical infrastructure remains unprepared

A news analysis describes US and allied warnings that Russian military intelligence units (including GRU Unit 29155 and GUGI) are conducting extensive scanning and reconnaissance of Western government and critical infrastructure, increasing use of zero-day exploits, and potentially preparing destructive cyberattacks that could produce physical harm (e.g., submarine cable sabotage). Agencies have issued advisories after evidence of large-scale scanning and historical GRU operations, and experts recommend patching, multi-factor authentication, and heightened defensive posture.
