Columbia University data breach settlement, compensation and claim questions

How much could a Columbia University data breach settlement or claim be worth?
There is no set amount, and no Columbia University settlement is confirmed here.

Keep receipts and records; they're what damages claims are built on.
Is there a Columbia University data breach class action lawsuit?
Law firms often open an investigation after a breach notice like this one, and a class action lawsuit may follow. This page doesn't confirm that a lawsuit has been filed against Columbia University. You usually don't have to join a class action to be included — if a settlement is reached, class members are notified and can file a claim.
Can I sue Columbia University over the data breach?
It depends on what was exposed, the law in NH and your own state, and whether you've been harmed. Most people take part through a class action rather than suing alone. Keep your notification letter — it's the proof that connects you to the breach.
Did Columbia University offer free credit monitoring?
