Was this a ransomware attack?

The filing does not say ransomware was involved. We do not label an incident ransomware unless the company’s report says so. Whatever the cause, the steps to protect yourself and the legal question are the same.

After the Tynan & Lannone incident: what to do and your options

What should I do after getting the Tynan & Lannone 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 Tynan & Lannone offer free credit monitoring?
Any free monitoring Tynan & Lannone is offering will be described in the notice you received, along with an activation code and a sign-up deadline. Enrolling does not give up your right to bring a claim.
Can I sue Tynan & Lannone over the data breach?
It depends on what was exposed, the law in Indiana 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 Tynan & Lannone data breach lawyer or attorney?
Whether the company's systems were encrypted by ransomware or data was simply taken, the legal question is the same: did it protect your information the way the law requires? An attorney can review your notice for free, and these cases are usually handled on contingency.
Is there a Tynan & Lannone data breach class action lawsuit?

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.
Is the Tynan & Lannone data breach letter legit or a scam?
A notice from Tynan & Lannone in the mail matches the breach Tynan & Lannone reported to the Indiana Attorney General on June 5, 2025. Check that the company name and dates in your letter match that filing. A real notice of data security incident won't ask for your password, Social Security number or a payment — if it does, contact Tynan & Lannone through a phone number or website you find yourself.
How much could a Tynan & Lannone data breach settlement or claim be worth?
There is no set amount, and no Tynan & Lannone settlement is confirmed here.
