Sounds like circulating air from the outside caused the mold. Any wind/air that gets in from the exterior will carry moisture with it at some point. Vapour barrier always goes on the warm side, so please ignore previous cold side comment. Good luck with every thing.
First, kill the mold with bleach and wipe down the whole area to try to get rid of as many spores as possible. Next, identify and treat the root cause. Mold at the bottom of the inside would suggest that interior condensation is pooling there. Window condensation is caused by two factors: Interior glass temperatures below the dew point Humid enough ...
To wipe, wear gloves and make a bucket of diluted Bleach (1 part bleach, 9 parts water). Use a rag or sponge to wipe the mold and clean the rag often in the bleach solution. The bleach will kill the mold and the damp rag will keep the spores down.
It's hard to tell from the picture but it looks like it was tile mounted to a wood board. Wood is one of the worst materials for behind the sink. If going to replace with tile, use a concrete backer board instead and consider using tile trim caps to cover the top. Otherwise use a solid stone or stone like material. And make sure the caulking is in good ...

I doubt it. I'd assume that any water which has made its way far enough into your house, to wet the backside of drywall, would have already alcamated. It's hard enough to find gaping holes in the exterior of a building by scanning a panel of drywall. Thermal cameras are used to find heat gain, standing inside, or heat loss, standing outside.

Spray foam might sound appealing as a quick fix, but will be a pain in the a** if you ever want to remove it! Here is an alternative solution: If you are convinced that building a small section around the old vent will work if you could make it waterproof, then try this instead: Similar to the way for building a fish tank, go out and get some thick ...
