These converters bridge legacy industrial equipment with modern networks, making them critical attack vectors into operational technology environments. With tens of thousands of these devices exposed online, the findings highlight how poor visibility and security practices around industrial networking equipment create significant attack surfaces that could impact utilities, manufacturing, and healthcare operations.","**Immediate actions:**\n- Patch affected Lantronix and Silex devices to latest firmware versions\n- Remove unnecessary internet exposure of industrial networking devices\n- Change default credentials on all serial-to-IP converters\n\n**Long-term improvements:**\n- Implement network segmentation to isolate OT devices from corporate networks\n- Establish regular vulnerability scanning for all industrial networking equipment\n- Maintain comprehensive asset inventory of all network bridge devices\n\n**Detection measures:**\n- Deploy network monitoring to detect unauthorized access to industrial devices\n- Enable logging on all serial-to-IP converters where supported",[12,13,14,15,16,17],"CIS Control 7","CIS Control 12","NIST CM-8","NIST SC-7","IEC 62443-3-3","NERC CIP-007","published","2026-04-22T07:09:37.645833+00:00","2026-04-22T07:09:37.335+00:00",{"id":7,"url":22,"slug":23,"title":24},"https:\u002F\u002Fwww.itsecurityguru.org\u002F2026\u002F04\u002F21\u002Fforescout-uncovers-new-security-risks-in-widely-used-industrial-networking-devices\u002F?utm_source=rss&utm_medium=rss&utm_campaign=forescout-uncovers-new-security-risks-in-widely-used-industrial-networking-devices","forescout-uncovers-new-security-risks-in-widely-used-industrial-networking-devic-ab9bcb","Forescout Uncovers New Security Risks in Widely Used Industrial Networking Devices",[26,32],{"id":27,"name":28,"slug":29,"description":30,"color":31},"05757c8d-6b93-4194-b35d-7359e7d33b0e","Vulnerability Management","vulnerability-management","Missing scans, no risk prioritization","#fb923c",{"id":33,"name":34,"slug":35,"description":36,"color":37},"f43a7f30-5046-4b10-9dba-1a704139821e","Network Segmentation","network-segmentation","Lateral movement, flat networks, missing firewalls","#06b6d4",[]]
