In February 2025, data from an earlier Adpost breach surfaced, containing 3.3 million records. Adpost later published a disclosure notice and advised that they had forced a credential refresh.
The confirmed data types exposed were email addresses, usernames, and display names. The breach affected an estimated 3.3 million individuals. It remains unclear if Adpost is a US-based company, which states were affected, or if any financial or medical data was involved.
Details can emerge later, and notices may be delayed.
