After the M Advisory Group incident: what to do and your options

What should I do after getting the M Advisory Group data breach notice?
Keep the letter and the envelope, and note the date it arrived. Freeze your credit with Equifax, Experian and TransUnion, change any passwords the notice mentions, and sign up for any free credit monitoring the letter offers. Then check whether you may have a claim.
Did M Advisory Group offer free credit monitoring?
Look for an enrollment code in your M Advisory Group notice. Companies that offer free credit monitoring after a breach usually include it there, with a deadline to activate. Using the free service won't stop you from joining a lawsuit or settlement later.
Can I sue M Advisory Group over the data breach?
It depends on what was exposed, the law in New Hampshire 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.
Do I need a M Advisory Group data breach lawyer or attorney?

How much could a M Advisory Group data breach settlement or claim be worth?
