The UK is working to identify any potential exposure following a global cyber-security warning that has prompted governments and companies to review the security of their websites.
Organisations are taking steps to protect their online services as they assess the possible impact of the threat. The available information does not specify which UK systems may be affected or describe the nature of the vulnerability involved.
Amazon said it had experienced attacks before the warning was made public. No further details have been provided about the attacks, including their targets, scale or impact.
The UK’s assessment is continuing, while governments and businesses respond to the warning and examine whether their websites or systems require additional protection. The latest situation remains subject to those checks.
