Executive Summary
In February 2018, a collection of almost 3,000 alleged data breaches was found online; 2,844 of the files contained more than 80 million unique email addresses not previously seen, each paired with a plaintext password. It was loaded as a single unverified compilation.
ObscureIQ assessment: A corpus this broad enables credential stuffing, account takeover, and identity correlation across many services because it concentrates reuse opportunities in one place. Its scale also makes it useful for phishing and fraud operations that need validated identities and long-tail historical credentials.
Breach Impact
As an aggregated credential set with plaintext passwords, it is directly usable for credential stuffing; presence indicates a credential is circulating, not that any specific company was breached.
About 2,844 Separate Data Breaches (compilation)
This record is a compilation of nearly 3,000 individual alleged data breaches assembled into a single corpus, not a breach of one organization.
Why They Hold Your Data
Multi-breach credential corpora combine usernames, email addresses, passwords, and related account identifiers from thousands of unrelated incidents into one searchable dataset. The workflow is large-scale aggregation, normalization, and packaging of credentials so they can be tested or resold more efficiently.
Recent Developments
Found online in February 2018, it was loaded as a single unverified dataset because its constituent sources could not be individually established.
