Britain’s hospitals have been brought to a standstill because of ransomware infecting obsolete and unpatched Windows XP systems. The same obsolete operating system is powering Britain’s nuclear weapons arsenal. Is it prudent to ask if the British nuclear weapons submarines have been patched against this ransomware, or even hit by it?As reported in January of last year, Britain’s nuclear submarines still run Windows XP. This is the outdated Microsoft operating system that was vulnerable to ransomware, and which is the reason that practically Britain’s entire healthcare is currently nonfunctional and at a standstill: they ran Windows XP, they did not upgrade, and they did not patch.(A security patch for this vulnerability has been out since March. Getting hit in May is therefore inexcusable.)I would argue that hospitals and nuclear weapons platforms are both “mission critical” for a government. It can be safely argued that one is more dangerous than the other, but in terms of how important to society it is to upgrade them and keep them current, they are playing in roughly the same division.
The UK nuclear subs also run Windows XP. Vulnerable to ransomware?
