What happened?
In December 2022, the online firearms auction website GunAuction.com suffered a data breach which was later discovered left unprotected on the hacker's server . The data included over 565k user records with extensive personal data including email, IP and physical addresses, names, phone numbers, genders, years of birth, credit card type and passwords stored in plain text. The leaked identities could subsequently be matched to firearms listed for sale on the website.
When did it happen?
The breach date in the public record is December 3, 2022. The record was added to the catalogue on March 2, 2023 and last updated there on March 5, 2023.
What information was reported as exposed?
- Browser user agent details
- Email addresses
- Genders
- IP addresses
- Partial credit card data
- Partial dates of birth
- Passwords
- Phone numbers
- Physical addresses
- Usernames
These are incident-level categories. The record does not prove that every category was exposed for every affected person.
Who may be affected?
This record may be relevant to people who had an account or other relationship with GunAuction.com or used gunauction.com around December 3, 2022. A catalogue entry does not establish that every customer was affected or that every listed data category applied to each person. Compare the record with an official notice addressed to you.
What should you do?
Compare the organization, dates, and information categories with any notice you received. Use contact details you independently confirm.
Change exposed or reused passwords, begin with your email account, and turn on multi-factor authentication where available.
Review your credit reports and consider a free credit freeze if identity information could support new-account fraud.
Check statements for unfamiliar activity and contact the card issuer or financial institution through an independently verified channel.
Choose actions that match the information involved. If you find signs that someone is using your identity, the Federal Trade Commission provides a personal recovery plan at IdentityTheft.gov.
