OSINT Breach Intelligence: Data Breach & Credential Exposure Detection

Overview#

In 2023, a large financial services firm discovered that credentials belonging to dozens of its developers had been circulating on a dark web marketplace for weeks before anyone noticed. The breach had gone undetected because no one was watching the right places. Breach Intelligence exists to close that gap: continuously scanning breach databases, dark web leak sites, paste platforms, and ransomware group pages so that when organisational credentials surface, security teams know within minutes rather than weeks.

With coverage spanning billions of indexed credentials and continuous dark web surveillance, the platform enables organisations to detect credential exposures early, prioritize remediation based on risk scoring, and stop account takeover attacks before they escalate.

Key Features#

• Breach Database Monitoring: Continuous surveillance across 40+ breach databases and dark web leak sites for organisational credential exposures, with automated authenticity validation and breach classification
• Credential Exposure Detection: Domain-specific email monitoring, executive account tracking, partner and vendor exposure monitoring, historical breach search, and real-time alerts on new exposures
• Password Intelligence: Password pattern analysis, reuse detection across breaches, strength assessment, corporate policy violation identification, and compromise timeline tracking
• Risk Scoring: Multi-factor risk assessment evaluating breach severity, password exposure, reuse patterns, account criticality, breach age, dark web activity, and PII exposure to generate prioritized remediation guidance
• Dark Web Leak Tracking: Monitoring of ransomware leak sites, credential marketplaces, paste sites, stealer log platforms, and Telegram channels for organisational data exposures
• Alert Notification System: Multi-channel alert delivery through Slack, Teams, PagerDuty, email, SMS, and SIEM integration with severity-based routing and customisable thresholds
• Executive Dashboard: Breach exposure overview, password intelligence analytics, breach source analysis, dark web activity tracking, remediation progress metrics, and compliance reporting
• Compliance Support: Automated workflows supporting GDPR Article 33 notification requirements, CCPA breach disclosure, HIPAA breach notification, SOC 2 documentation, and ISO 27001 incident management

Use Cases#

• Executive Credential Protection: Monitor C-suite and board member accounts with enhanced alerting, dedicated security liaison notifications, and immediate remediation workflows for high-value credential exposures
• Enterprise Security Operations: Integrate breach intelligence into SOC workflows with automated SIEM forwarding, SOAR playbook triggers, and identity management system integration for automated password resets
• Healthcare Compliance: Monitor PHI access accounts for credential exposure, automate HIPAA breach notification workflows, and maintain compliance documentation for HHS reporting
• Developer Account Security: Track developer credentials across code repositories, cloud service accounts, and API key exposures on paste sites with automated token rotation workflows
• Supply Chain Risk Management: Monitor third-party vendor and partner credentials for exposure, assess supply chain breach risk, and coordinate remediation across organisational boundaries

Integration#

The platform integrates with identity management systems (Active Directory, Okta, Azure AD) for automated remediation, SIEM platforms (Splunk, Sentinel, QRadar) for event correlation, SOAR platforms for orchestrated response workflows, and password management solutions for compromised credential detection. Webhook delivery supports custom integrations with existing security tooling. The module also connects to the broader Argus OSINT ecosystem including dark web monitoring, threat intelligence feeds via STIX/TAXII, and MISP for malware-linked credential exposure.

Open Standards#

• STIX 2.1 (OASIS CTI TC): Breach and credential exposure indicators are represented as STIX 2.1 Indicator, Identity, and Observed Data SDOs, enabling bidirectional exchange with any STIX-aware threat intelligence platform or SIEM.
• TAXII 2.1 (OASIS CTI TC): The platform subscribes to external breach intelligence feeds and pushes findings over an async TAXII 2.1 polling client, using the standard application/taxii+json;version=2.1 content type and X-TAXII-Date-Added-Last pagination header.
• MITRE ATT&CK: Credential theft and account takeover activity is mapped to ATT&CK techniques and tactics, allowing TTP-based attribution of breach sources and integration with SOC workflows that use ATT&CK identifiers.
• Sigma: Breach-derived detection rules are authored and stored in Sigma format, with pySigma translation backends enabling deployment directly to Splunk, Microsoft Sentinel, QRadar, and Elasticsearch without manual query rewriting.
• MISP Core Format 2.4: The platform federates with MISP instances to correlate credential exposures with malware-linked events, exchanging threat events and attributes in the MISP Core Format.
• CVE / CVSS v3: Where a breach is associated with an exploited vulnerability, the platform records the CVE identifier and CVSS v3 base score and vector string to support risk-based prioritisation of remediation.
• GraphQL: All breach intelligence queries, mutations, and real-time subscriptions are exposed through a GraphQL API, providing a strongly typed, self-documenting interface for SOC tooling and identity management integrations.
