Alien TxtBase

In early 2025 the Alien TxtBase collection was released via a Telegram channel containing a massive aggregation of data harvested through information stealing malware. While initial claims suggested 23 billion lines the dataset was found to contain significant duplicates and generated entries. After rigorous cleaning and removal of known data from sources like NAZ.api approximately 2.8 billion unique records remained. The breach consists of credentials stolen directly from browser storage across various platforms and applications globally. The records include sensitive login details such as emails and plain text passwords associated with specific websites and local applications.
