An easy way is to just go visit port 16992/tcp on your device. - To be extra sure, you can also run nmap to scan the port from a different device. -This is not a hidden thing at all, people have accidentally run into it on social media: - -![Intel AMT](/images/intel-amt.png) +This is not a hidden thing at all, people have accidentally [run into it on social media](). For attack surface reduction, you should absolutely disable it. With that said, don't let the scary claims about "remote management" spook you - if some sort of hypothetical backdoor actually implemented this way, it is not hard to detect. There are better ways to implement a backdoor as discussed above, and if you don't trust the CPU vendor you should avoid them as a whole, not just the vPro model. diff --git a/static/images/intel-amt-misinfo.png b/static/images/intel-amt-misinfo.png new file mode 100644 index 0000000..27a8ab2 Binary files /dev/null and b/static/images/intel-amt-misinfo.png differ diff --git a/static/images/intel-amt.png b/static/images/intel-amt.png deleted file mode 100644 index 26caa52..0000000 Binary files a/static/images/intel-amt.png and /dev/null differ
