UK cybersecurity officials report that state-linked hackers from Iran and China are responsible for most "nationally significant" cyberattacks targeting British infrastructure and institutions.

The warning comes from the UK's top cybersecurity official, who noted that foreign government-backed threat actors now conduct the majority of major cyberattacks against the country. Iran and China represent the primary sources of these state-sponsored operations, targeting critical sectors and sensitive systems. The attacks have grown in frequency and sophistication, prompting increased concern among British security agencies. The assessment reflects broader geopolitical tensions and the expanding use of cyberweapons by hostile nations. UK officials have emphasized the need for stronger defenses across government and private sector infrastructure. This warning aligns with similar assessments from Western intelligence agencies, which have consistently identified state-sponsored cyber programs as major threats. The UK continues to develop countermeasures and improve incident response capabilities in response to the escalating threat landscape.
