IoT and smart home devices are frequently overlooked in patch cycles, leaving them exposed long after fixes become available. This matters because compromised smart TVs can serve as pivot points for deeper network intrusions, enabling attackers to move laterally to more sensitive systems. LG has released a patch, but the window of exposure highlights how unmanaged consumer and enterprise IoT devices remain a persistent blind spot in network security posture.","**Immediate actions:**\n- Apply LG's released webOS security patch immediately across all affected smart TV models.\n- Isolate smart TVs and other IoT devices onto a dedicated VLAN or guest network segment to limit lateral movement potential.\n\n**Long-term improvements:**\n- Maintain a comprehensive inventory of all networked IoT and smart devices to ensure none are missed in future patch cycles.\n- Establish a formal IoT device lifecycle policy that includes firmware update schedules, end-of-life replacement criteria, and security baselines.\n- Require vendors to provide timely security patch SLAs and validate secure-by-default configurations before deploying smart devices on corporate or home networks.\n\n**Detection measures:**\n- Deploy network monitoring tools (e.g., NDR\u002FIDS) capable of detecting anomalous lateral movement or unexpected traffic originating from IoT devices.\n- Regularly audit network-connected devices for unpatched firmware using automated vulnerability scanning tools.",[12,13,14,15,16,17,18,19],"CIS Control 1 – Inventory and Control of Enterprise Assets","CIS Control 7 – Continuous Vulnerability Management","CIS Control 12 – Network Infrastructure Management","NIST SP 800-213 – IoT Device Cybersecurity Guidance","NIST SI-2 – Flaw Remediation","NIST SC-7 – Boundary Protection \u002F Network Segmentation","NIST IR 8259 – Foundational Cybersecurity Activities for IoT Device Manufacturers","ETSI EN 303 645 – Cyber Security for Consumer IoT (Clause 5.3: Keep software updated)",{},"published","2026-10-13T12:21:16.070903+00:00","2026-10-13T12:21:15.988+00:00",{"id":7,"url":25,"slug":26,"title":27},"https:\u002F\u002Fthehackernews.com\u002F2026\u002F10\u002Flg-smart-tvs-vulnerable-to-pre-auth.html","lg-smart-tvs-vulnerable-to-pre-auth-root-takeover-from-local-network-1cc27b","LG Smart TVs Vulnerable to Pre-Auth Root Takeover From Local Network",[29,35,41],{"id":30,"name":31,"slug":32,"description":33,"color":34},"05757c8d-6b93-4194-b35d-7359e7d33b0e","Vulnerability Management","vulnerability-management","Missing scans, no risk prioritization","#fb923c",{"id":36,"name":37,"slug":38,"description":39,"color":40},"af7fce9e-1ce8-4156-93bc-09dcfbfdf29d","Patch Management","patch-management","Unpatched vulnerabilities, delayed updates","#ef4444",{"id":42,"name":43,"slug":44,"description":45,"color":46},"f43a7f30-5046-4b10-9dba-1a704139821e","Network Segmentation","network-segmentation","Lateral movement, flat networks, missing firewalls","#06b6d4",[48],{"id":49,"date":50,"edition":51,"title":52,"audio_url":53},"2d588081-a5ac-47ad-93c0-8a8b71bc70ab","2026-10-13","afternoon","ThreatNoir Afternoon Brief — October 13","https:\u002F\u002Fcdn.threatnoir.com\u002Fpodcasts\u002F2026-10-13\u002Fthreatnoir-afternoon-brief-2026-10-13.mp3",[55,58,62],{"slug":32,"name":56,"problem":57},"Vulnerability scanning and prioritisation","You know which systems are vulnerable, and which ones to fix first.",{"slug":59,"name":60,"problem":61},"endpoint-detection-response","Endpoint detection and response (EDR and XDR)","Malware and hands-on-keyboard attackers on laptops and servers get spotted and stopped.",{"slug":44,"name":63,"problem":64},"Network segmentation and microsegmentation","One compromised machine can no longer reach everything else."]
