Researchers uncovered an exposed Elasticsearch database containing roughly 24 billion plaintext credential records, including usernames, email addresses, passwords, and associated login URLs. The dataset was estimated at more than 8 terabytes and appeared to aggregate data from 36 sources, including infostealer logs, Telegram channels, prior breach collections, local database dumps, and exports from live servers. Investigators said the database was publicly accessible before being taken offline, but the owner could not be identified.
The exposed records create a significant risk of credential stuffing, account takeover, and broader identity abuse at global scale, especially for users who do not use multi-factor authentication. Researchers reported that more than 30 of the sources were linked to Telegram channels and that 22.6 billion entries were broadly labeled as “collections,” while signs of regular updates suggested the dataset was being actively curated. They also found records referencing CVE identifiers, GitHub links, breach news, and social media posts about incidents, indicating the operator may have been monitoring the cybersecurity landscape while maintaining the credential trove.

The exposed database was taken offline shortly after researchers discovered it. Researchers still could not identify the owner, determine the age of most records, or assess the full extent of duplication and affected individuals.
Cybernews researchers found an exposed Elasticsearch cluster on June 12 containing roughly 24 billion records and more than 8.3 TB of data. The dataset largely consisted of stolen credentials, including usernames, email addresses, plaintext passwords, and associated URLs aggregated from 36 sources such as infostealer logs, Telegram channels, and breach collections.
