mle✨<p>Our team at <span class="h-card" translate="no"><a href="https://infosec.exchange/@censys" class="u-url mention" rel="nofollow noopener" target="_blank">@<span>censys</span></a></span> has studied Internet exposure of <a href="https://infosec.exchange/tags/ICS" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ICS</span></a> for the better part of a year, learning more about the products, protocols, and nuances of this space. </p><p>Today I'm excited to share our third annual ✨State of the Internet Report detailing what we've learned! A few highlights:</p><p>🛜 Most ICS protocols and HMIs we've observed run on 5G/LTE (e.g., Verizon) or SOHO/business-grade ISPs (e.g., Comcast). We initially observed this in the U.S. and in this most recent research found that it's a global phenomenon. This surprised me initially, but industrial devices often need to run in places where a wired connection might not be available. While great for connectivity, use of such networks makes it often impossible to determine who owns or operates a given service, as the host metadata points back to the telco itself. </p><p>💧 Analysis of over 200 C-More human-machine interfaces (HMIs) revealed over a third appear to be related to water and wastewater systems (WWS). WWS has seen increased targeting over the last ~year, and these exposures suggest still more work is needed to adequately protect and defend this sector. </p><p>⛔️ We found nearly 200 hosts globally running HMIs alongside products banned by U.S. NDAA Section 889. While this act applies only to a specific set of operators within the U.S. federal government, it's interesting to note what technologies operators implement alongside potentially critical services.</p><p><a href="https://infosec.exchange/tags/infosec" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>infosec</span></a> <a href="https://infosec.exchange/tags/cybersecurity" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>cybersecurity</span></a> <a href="https://infosec.exchange/tags/OT" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>OT</span></a> </p><p>You can find a copy of the report with all the details here! 👇</p><p><a href="https://censys.com/the-2024-state-of-the-internet-report/" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">censys.com/the-2024-state-of-t</span><span class="invisible">he-internet-report/</span></a></p>
