What to Do After a Data Breach Notice
By eosguide team · April 29, 2026 · 5 min
You got a letter. It came in a white envelope that looked like junk mail, or an email with a long subject line, or possibly both. It expressed deep regret. It told you your data "may have been" accessed — which is corporate for "was accessed." It offered you free credit monitoring for 12 months — which is corporate for "please don't sue us individually."
Here's what to actually do.
First: what did they get?
The right steps depend on what was exposed. Not all breaches are the same — a leaked email address and a leaked Social Security number have very different consequences. Select what applies to you.
SSN exposure is the long game. Your Social Security number doesn't change. A fraudster who bought it in 2026 can try to use it in 2031. The steps below aren't optional maintenance — they're damage control with a very long tail.
Financial account data moves faster than SSNs. Credit card numbers get sold and used quickly — often within days. The good news: they're also easier to cancel and replace than a Social Security number.
Medical data is the breach that keeps giving. You can cancel a credit card in five minutes. You cannot cancel your medical history, insurance ID, or Medicare number. Health data enables insurance fraud that can take years to surface — and often longer to untangle.
Email and password breaches are credential-stuffing fuel. Attackers run your username and password combination against hundreds of other sites automatically. If you've reused that password anywhere — banking, email, shopping — go change it now, before you read anything else on this page.
Multiple data types means maximum exposure. Start with the highest-risk items first. SSN or medical data first, then financial accounts, then credentials. Working methodically is better than panicking and doing nothing.
The vagueness is intentional. Breach notices are drafted by legal teams managing the company's liability exposure at the same time they're informing you of a risk to yours. "May have been accessed" means it was. "Various personal information" means they'd rather not enumerate.
