Two issues in one that nullify SSL in foscam devices: All Foscam networked cameras use the same SSL private key that is hard coded into the downloadable firmware. This is easily extracted using a utility like binwalk and would allow an attacker to MITM any Foscam device. One devices SSL keys are valid for any other device. See the below certificates CNs: *.myfoscam.org Below are the ssl certificates of two foscam devices. openssl s_client -connect [REDACTED]myfoscam.org:443 CONNECTED(00000003) depth=0 C = CN, ST =
