From their website, I get that CMU&#x2F;SEI&#x2F;CERT works with both DHS and DoD.[0] Although I don&#x27;t see anything specific about the FBI, it&#x27;s not too much of a stretch. As DHS has grown and evolved since 9&#x2F;11, distinctions between police and military have weakened. A decade ago, CERT would have been carefully shielded through parallel construction.<p>In my opinion, this is a wakeup call for the Tor Project. The attack would have been obvious if they&#x27;d been tracking the requisite circuit parameters. Ironically enough, it strikes me that the Tor network needs something like CERT for detecting attacks.<p>[0] <a href="https:&#x2F;&#x2F;www.cert.org&#x2F;about&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.cert.org&#x2F;about&#x2F;</a>
