I spent all day looking for vulns in a IoT clothes dryer. What did I find?
* HTTPS to talk to backend service
* XMPP w/ STARTTLS to steam events
* Cert pinning so no MitM
* Android app obfuscated w/ no obvious backend URLs or certs
* Dryer runs an AP for initial setup w/ DHCP and HTTPS servers
* That HTTPS requires auth with a password printed on a label near the door
Best I could do was get the DHCP server to serve the same IP to every request.
Well done GE.
Another day, another set of BMC vulns. https://eclypsium.com/2019/07/16/vulnerable-firmware-in-the-supply-chain-of-enterprise-servers/ #iWorkThere #BackdoorManagementController

I did a podcast interview: https://unnamedre.com/episode/24
I'm in awe of how many links are in the show notes. We covered a _lot_ of topics.
