Cybersecurity: Threats and DefencesBackground
MicroLogix is Rockwell Automation's line of programmable logic controllers, small industrial computers used to automate machinery and processes in manufacturing and utility settings. The 1100 and 1400 models are the versions named in advisory SD1790.
That advisory, published 30 July 2026 and revised the next day, carries no attached CVE and offers steps to recover a locked device rather than a fix for a discovered vulnerability. CISA's own alert on the matter cited NCSC's Secure Connectivity Principles for Operational Technology guidance, which predates the advisory by more than two years, a chronology worth noting precisely rather than glossing over.
No exploitation, attacker technique or affected-customer count has yet been reported for this advisory.
