Paco Hope #resist<p>Some of my colleagues at <a href="https://infosec.exchange/tags/AWS" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>AWS</span></a> have created an open-source <a href="https://github.com/awslabs/threat-designer" rel="nofollow noopener" target="_blank">serverless #AI assisted #threatmodel solution</a>. You upload architecture diagrams to it, and it uses Claude Sonnet via Amazon Bedrock to analyze it.</p><p>I'm not too impressed with the threats it comes up with. But I am very impressed with the amount of typing it saves. Given nothing more than a picture and about 2 minutes of computation, it spits out a <em>very</em> good list of what is depicted in the diagram and the flows between them. To the extent that the diagram is accurate/well-labeled, this solution seems to do a very good job writing out what is depicted.</p><p>I deployed this "Threat Designer" app. Then I took the architecture image from <a href="https://medium.com/serverless-transformation/what-a-typical-100-serverless-architecture-looks-like-in-aws-40f252cd0ecb" rel="nofollow noopener" target="_blank">this blog post</a> and dropped that picture into it. The image analysis produced some of the list of things you see attached.</p><p>This is a specialized, context-aware kind of OCR. I was impressed at boundaries, flows, and assets pulled from a graphic. Could save a lot of typing time. I was not impressed with the threats it identifies. Having said that, it did identify a handful of things I hadn't thought of before, like EventBridge event injection. But the majority of the threats are low value.</p><p>I suspect this app is not cheap to run. So <em>caveat deployor</em>. <br><a href="https://infosec.exchange/tags/cloud" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>cloud</span></a> <a href="https://infosec.exchange/tags/cloudsecurity" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>cloudsecurity</span></a> <a href="https://infosec.exchange/tags/appsec" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>appsec</span></a> <a href="https://infosec.exchange/tags/threatmodeling" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>threatmodeling</span></a></p>
