German police and intel agencies sent 440,000 sms type0/stealth attacks to trace phones last year, FBI sent an OTA to a suspects internet stick to broadcast his location, and something shady is going on at airports according to Cryptophone GSMK who's radio 'firewall' goes off whenever you get near an airport. Besides that Samsung backdoor found by Replicant Mod that has access to /data and /sdcard haven't heard of other directed attacks yet.

Of course google can install whatever they want on your device if given a NSL including a modified WhatsApp that sends in plaintext straight to the police everything you type but haven't heard of that yet either.

Since Facebook makes money harvesting data wonder if WhatsApp grabs advertising keywords first then sends via textsecure layer.
