Flying over the hills under ZZZ Class Bravo Airspace in IMC and Terrain Awareness (EPGWS) activated with a 'Terrain Terrain Pull Up' aural command. I clicked the TOGA (Takeoff/Go-Around) button and began a climb and briefly entered visual conditions with some terrain in sight. We advised ZZZ [TRACON] of our climb. ZZZ [TRACON] was perplexed as he stated that the Minimum Vectoring Altitude in our sector was 3;200 [feet] MSL. We were instructed to maintain 3;500 [feet] MSL and the flight continued without incident.Event due to possible sensitive Terrain Awareness Warning System/EGPWS. The crew treated the event as a terrain threat an acted accordingly.
EMB-145 Captain reported climbing after receiving an EGPWS warning that appeared to be false.
