Wake-Up Call for CNI After Iranian Attack Shuts Down UK Power Plant
An Iranian cyberattack that temporarily shut down a UK power plant has prompted warnings from security experts about vulnerabilities in critical national infrastructure. Analysts say the incident exposes inadequate defenses across key sectors and are calling for urgent investment in cybersecurity measures, improved threat intelligence sharing, and stronger regulatory frameworks to protect essential services from increasingly sophisticated state-sponsored attacks.
Hackers are using “evolved” capabilities in AI-generated malware to hit US critical infrastructure at an unprecedented scale — “active threat” currently hitting energy, water and agricultural industries
Hackers are using AI-generated malware to attack US critical infrastructure at an unprecedented scale, targeting energy, water, and agricultural sectors. The ongoing campaign exploits internet-facing Siemens S7 Series programmable logic controllers to identify targets. Officials describe it as an active threat, with attackers demonstrating evolved capabilities attributed to AI-assisted tools.
National infrastructure needs a new approach to cyber resilience
Public ownership of national infrastructure does not protect against cyber threats. Britain needs a new approach based on shared intelligence between public and private sectors, clearer prioritisation of risks, and better coordinated resilience planning. Structural ownership matters less than how organisations prepare, communicate and respond to attacks.
Gunra Ransomware Exploits Fortinet and Schneider Electric Flaws to Breach Networks
Matched: health
South Korean and US cybersecurity agencies have warned about Gunra ransomware targeting critical infrastructure globally, including healthcare, financial services, government, and nonprofit sectors. The attacks exploit vulnerabilities in Fortinet and Schneider Electric systems. Gunra follows a ransomware-as-a-service model and represents a continuing trend of sophisticated ransomware variants threatening essential services worldwide.
Australian startup Quantum Lock applies quantum physics to detect cyberattacks on embedded devices
Matched: Australia
Australian startup Quantum Lock is using quantum physics to detect cyberattacks on embedded devices in critical infrastructure. The technology offers continuous monitoring to identify compromised devices, moving beyond traditional point-in-time security checks. The approach targets sectors where embedded systems are common and difficult to secure, positioning the startup as an early mover in quantum-based cybersecurity for industrial and critical infrastructure environments.
Not a drop to drink: Unknown attackers are targeting US water systems… And it could happen here
Matched: Australia
US water utilities have been targeted by cyberattacks, with Iran suspected though unconfirmed. Attackers exploited internet-exposed industrial control systems, some still using default passwords. The incidents highlight vulnerabilities in critical infrastructure globally, with Australian operators urged to audit their systems, restrict remote access, update credentials, and apply patches to operational technology environments.
10th August – Threat Intelligence Report
North Carolina Ports suffered a cyberattack disrupting operations at Wilmington, Morehead City and other ports, forcing some processes to revert to manual operation. The authority says the incident has been contained. Additional details on other attacks, breaches, vulnerabilities, and threat intelligence findings are available in Check Point Research's full Threat Intelligence Bulletin for the week of 10th August.
3rd August – Threat Intelligence Report
Minnesota IT Services confirmed coordinated cyberattacks on over 30 community water utilities, briefly disrupting a treatment plant in Braham and affecting industrial control systems. The incidents highlight ongoing vulnerabilities in critical infrastructure. Further details on this and other threats are available in Check Point Research's weekly Threat Intelligence Bulletin for the week of 27th July.
ASD to critical infrastructure ops: be ready to isolate systems for three months
Matched: Australia
Australia's Australian Signals Directorate has issued new technical guidance urging critical infrastructure operators to prepare for the possibility of isolating their systems for up to three months following a cyberattack. The advice targets essential services sectors and focuses on building resilience and recovery capabilities to maintain operations even when disconnected from broader networks.
Australian critical infrastructure urged to tighten router security after Russian cyber warning
Matched: Australia
Australia's cyber security agency has joined international partners in warning critical infrastructure operators to strengthen the security of routers, firewalls and other network devices following alerts about Russian state-sponsored cyber threats. Operators are being urged to review configurations, apply patches and monitor for suspicious activity to reduce the risk of compromise to essential services.
