Unique emails by Addka

In September 2024 a threat actor known as Addka72424 shared a massive compilation of data on BreachForums. The dataset initially totaled 70GB and contained approximately 3.2 billion unique email addresses gathered from numerous previous breaches and diverse sources. After deduplication and filtering against existing known major leaks it was determined that around 270 million of these addresses were previously unseen or newly indexed for search. This incident represents a significant aggregation of credentials and contact information compiled over time from various cyber attacks and data exposures.
