Autofill Data
Also known as: Browser autofill, Form autofill data
Autofill data is the information browsers save to automatically complete forms — names, addresses, phone numbers, emails, and sometimes payment details. Infostealers extract autofill data, exposing personal information that aids fraud and social engineering.
What is autofill data?
Browsers store autofill profiles to speed up form completion. This can include contact details, mailing addresses, and saved payment information — a rich set of personal data tied to the user.
Why attackers want autofill data
Beyond passwords, autofill data gives attackers the personal details needed for identity theft, convincing phishing, and account-recovery abuse. It is a standard collection target for infostealers.
VantaPrism parses autofill and PII present in stealer logs, helping teams understand the full scope of personal data exposed by an infection — not just credentials.
