British organisations have been warned to bolster their digital defences due to "malicious" cyber incidents in Ukraine.
The National Cyber Security Centre (NCSC) has updated its guidance to UK firms and groups and said it is is investigating the recent reports of "malicious cyber incidents in Ukraine".
The NCSC said it had not identified any current threats to the UK, but noted its updated guidance would allow organisations "to build resilience and stay ahead of potential threats".
