Stains of walls

[Bruce M. Sutherland]

Can someone help me with identyfing these dark shadowy spots along the ceiling joist and wall studs behind the drywall throughout this home. It's pretty much in every room, with the exception that one of the bedrooms was really worse than the others. There were no signs of previous moisture intrusion anywhere around the house. It had been winterized over the winter and de-winterized before the inspection. The home buyer was a previous builder and the realtor even said they had never seen anything like this before. Any ideas?
