Understanding your Microf data breach notification letter
If a Microf letter arrived in your mailbox, here is what it means, why you received it, and the free steps you can take right now.
Why you received this letter
Microf, a financial services company, filed a data security incident report with the Massachusetts Attorney General's office on December 23, 2025. The company is currently investigating the incident, which may have exposed personal information. This filing confirms a breach event for individuals who may have received a direct notification.
What to do after the letter
Confirm the notice is genuine
A legitimate Microf notice references the specific incident reported to the Massachusetts Attorney General and describes which categories of your information were involved. Compare the letter against the public filing before acting on any links or phone numbers it contains.
Keep the letter — it is your proof of connection
The notification letter is the document that ties your personal information to this incident. Keep the original and photograph it. If you later request a case review, this letter is the strongest evidence that you were among the affected individuals.
Protect your accounts and credit
Depending on what was exposed, consider a free credit freeze with all three bureaus, new passwords for reused credentials, and monitoring of financial statements. These steps are free and do not require you to wait for anyone's permission.
