Reading the thread from the startt, it seems that Baidu is used for pushing content to MyXperia.

MyXperia is their service similar to let you can remotely track or lock your device. My guess is they are using Baidu's push service to send the commands to device.

So I'd say this is a poor choice of service provider from Sony - especially for non-Chinese versions - but _probably_ harmless.

At best, as harmless as Google's command & control channel to Android devices (=not very).
