IntelligenceX Data Breach
IntelligenceX Open-Source Intelligence Paste Scrape (2021): 92 Million Indexed Email Addresses Exposed
Data indexing and intelligence search platform.
Risk Interpretation
Exposure can reveal investigative interest, target selection, and user behavior patterns. This creates phishing risk, operational-security risk, and possible retaliation against researchers or investigators.
Impact & Downstream Threats
In approximately August 2021 an attacker scraped the "Pastes" section of the Intelligence X platform by enumerating searches using common email domains, harvesting approximately 92.6 million email addresses that had appeared in paste content indexed by the service. The irony of a breach intelligence platform appearing in a breach intelligence dataset was noted in security community coverage. Intelligence X characterized the incident as scraping of publicly indexed content rather than a compromis

Executive Summary
Intelligence X, the investigative search and archival platform operating at intelx.io, was targeted by a scraping attack in approximately August 2021. An attacker harvested data from the platform's publicly indexed "Pastes" section by running systematic searches across common email domains and exporting the results. The scraped archive contained over 80,000 pastes drawn from pastebin.com, pastie.org, and skidpaste.org, yielding approximately 92.6 million records and 46 million unique email addresses. Intelligence X characterized the incident as scraping of publicly indexed content rather than a breach of its core systems. The exposed data consisted of email addresses only, many appearing within email and password combolists or small databases that had been posted to paste sites. No passwords or additional personal information were confirmed as part of the scraped output. However, for the platform's user base of security researchers, journalists, and intelligence professionals, even email exposure carries distinct risks. Knowing who uses a breach intelligence tool can reveal investigative interests, active cases, or professional affiliations, making affected users potential targets for phishing, social engineering, or retaliation. No regulatory action or litigation specific to this incident has been publicly documented. Affected individuals should be alert to phishing attempts and review any accounts tied to exposed email addresses for signs of unauthorized access. Those working in sensitive investigative or security roles should consider whether their professional email exposure creates operational security concerns.
