Adpost Data Breach (2025)

If you are a customer of Adpost, here’s what’s now in circulation.

In February 2025, data obtained from an earlier Adpost breach surfaced. The dataset contained 3.3M records including email addresses, usernames, and display names. Adpost later published a disclosure notice and advised they'd forced a credential refresh, among other actions.

Adpost Data Breach (2025)

On February 14, 2025, a dataset containing records for 3.3 million Adpost users appeared in public forums. The exposed information includes email addresses, usernames, and display names tied to the classifieds platform. Anyone who created an account on Adpost is potentially affected, along with family members whose contact details were linked to those accounts.

What's Publicly Reported from Reporting

Public reporting from Have I Been Pwned confirms the breach surfaced in February 2025. The dataset stems from an earlier intrusion that Adpost later attributed to compromised credentials. In its disclosure notice, the company stated it had forced a credential refresh for impacted accounts and taken additional security steps. The records contain email addresses, usernames, and display names but do not appear to include passwords or financial data according to available reporting.

Why This Matters for You and Your Family

A breach of this scale means your email address and username are now easily searchable by anyone with basic technical skills. Once those details are out, they can be combined with information from other leaks to build a profile of you and your household. Children who used family email addresses for accounts may also find their usernames exposed, increasing risks of harassment or unwanted contact. The incident shows how even platforms used for everyday buying and selling can put personal identifiers into circulation.

The Doxxing and Identity-Chain Implications

Usernames and display names often stay consistent across gaming platforms, social media, and forums. A single leaked username can serve as the starting point for attackers to link your online handles to your real identity. This creates an identity chain that leads to doxxing, where private details such as home addresses or phone numbers are published. Credential leaks like this one frequently cascade into account takeovers on other services where the same email and password combination was reused. Gaming accounts belonging to you or your children are particularly vulnerable because they often share the same email domain and can be hijacked to harass or extort.

What to Do

  • Rotate the password used on Adpost anywhere it is reused and switch to 2FA through an authenticator app rather than SMS.
  • Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, with cleanup included.
  • Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure is caught in hours, not months.
  • Cover the household with DoxxScan family coverage that extends to dependents and children's gaming accounts that chain back to the same address.
  • Let remediation specialists handle takedown requests across data brokers and exposed profiles on your behalf.
