Hiden encrypted HTTPS connections to Blackberry servers
Hello
When I look at tcpdump output I can see that there are a bunch of background connections are made by the blackberry. One of them is HTTP and I can see it's probably just to check that my wi-fi connection works and we're connected to the internet. There is no special data transmitted there.
But 3 other connections are using TLS and thus I can't see the data being transmitted. The DNS lookups made by the device go to icc.blackberry.com and inet.icrs.blackberry.com. Behind that are CNAMEs to eu.icrs.dyn.blackberry.net here in Germany, which is 178.239.90.160. The other two TLS connections I'm not sure which domain name is behind, but the IPs belong to blackberry, too. They are: 74.82.89.17 and 93.186.27.162
I'd like to know what is being transmitted, why and how to turn it off.
Thanks
