Hard brown sugar isn't ruined. It dried out. The molasses inside the sugar evaporated and the granules bonded together into a brick. Pretty much every household has a forgotten bag like this somewhere.
The fastest fix is the microwave with a damp paper towel. Steam from the towel re-moistens the sugar without melting it, and the whole thing takes about a minute. Use this when you're already in the middle of a recipe and need usable brown sugar right now.

Slow alternative: if you've got a couple of days, drop a fresh slice of bread directly into the container with the sugar and seal it. The bread quietly transfers moisture to the sugar over two to three days. The bread won't mold. To stop the problem from coming back, store brown sugar in an airtight container with a slice of bread for the long haul.
Tip the hardened brown sugar out of the bag or container into a microwave-safe glass bowl. Break up any large bricks with your fingers or a fork as you go.
Smaller pieces let steam reach all of it. One giant solid chunk takes a lot longer to soften, and the outside ends up melting before the inside loosens.
Run a paper towel under the tap, then squeeze out most of the water until it's damp but not dripping. The little bit of moisture trapped in the towel is what's about to release back into the sugar as steam.
If the towel is sopping wet, water drips into the sugar and you end up with a gummy mess instead of softened sugar. Damp is the target.
Drape the damp paper towel over the top of the bowl, with the towel resting across the rim. The key detail here is that the towel does not touch the sugar directly - it sits over the opening so the steam reaches the sugar from above.
Once the towel is in place, slide the whole bowl into the microwave.
Tip
If your towel keeps slipping off, pinch the corners under the rim of the bowl. Just don't tuck it down to the sugar.
Set the microwave for 20 seconds. Twenty is the safe ceiling - any longer and you risk melting the sugar into a sticky lump that's worse than where you started. Hit start and wait it out.
The wattage on your microwave matters here. A 1000W or higher microwave may need only 15 seconds per burst. Lower-wattage units may need a few extra seconds. Start at 20 and adjust down if the sugar feels warm too quickly.
Open the microwave, take the towel off, and stir the sugar with a fork. Break up any clumps that are still hard. The fork works better than a spoon because the tines push into the chunks.
Re-cover with the towel, microwave another 20 seconds, and stir again. Most batches come back to soft after two or three rounds. Stop the moment the sugar moves like fresh sugar - the texture should pour, not crumble.
Tip
If a corner of sugar started melting and turned syrupy, scrape it out and continue with the rest. The melted bit is fine for cookies but will throw off measurements in a structured bake.
