Russian state-sponsored hackers are actively targeting Western organizations supporting Ukraine, prompting a joint cybersecurity warning from the UK, US, and several allies, according to sources.

Britain, along with allies including the United States, has issued a joint advisory warning of a Russian state-backed cyber campaign targeting organisations involved in supporting Ukraine. The alert, released on Wednesday, highlights a growing threat to Western logistics, technology firms, and critical infrastructure.

According to the UK’s National Cyber Security Centre (NCSC), the cyber operations are being carried out by Russia’s military intelligence service and pose a significant risk to entities delivering aid to Ukraine.

“This campaign presents a serious risk to targeted organisations, particularly those providing assistance to Ukraine,” said Paul Chichester, Director of Operations at the NCSC.

The advisory, released in coordination with the US, France, Germany, and other NATO allies, said sectors such as defence, IT services, maritime transport, airports, ports, and air traffic management systems have also been targeted in multiple NATO countries.

Officials are urging organisations across these sectors to review the guidance and take immediate steps to bolster their cybersecurity.

“We strongly recommend organisations familiarise themselves with the threat landscape and take action using the mitigation strategies outlined in the advisory,” Chichester added.
