Threat landscape

Hidden Credential Leaks Enable Silent Attacks

Credentials are the new perimeter, and criminals already own them. Infostealers harvest billions of credentials yearly and sell them across stealer markets and dark web channels within hours. Most organizations discover exposures only after account takeovers and fraud have already occurred, because conventional security tools watch internal systems and miss what is actively traded on the other side of the web.

ZeroFox Compromised Credentials Monitoring Solution

Unlike tools that recycle breach dumps or rely on scrapers, ZeroFox delivers operative dark web intelligence. It combines covert collection across stealer markets and closed forums with the Intelligence Evidence Graph and Global Disruption Network (GDN) to provide earlier visibility, richer context, and high-confidence alerts for rapid response.

Detect employee credentials in fresh stealer logs or dark web marketplaces.

Frequently asked questions

ZeroFox CTI Compromised Credentials Intelligence is a threat intelligence capability that detects, enriches, and prioritizes exposed credentials across the surface, deep, and dark web so security teams can respond before attackers succeed. It provides real-time visibility into credential exposures through the Intelligence Evidence Graph with over 12 billion correlated data points.
Security operations, threat intelligence teams, identity and access management, fraud prevention, executive protection, and incident response teams all use credential intelligence to stop account takeover, reduce breach impact, and protect high‑risk users. IT security teams responsible for password policy and access controls also benefit from early warning of credential compromise.
The Intelligence Evidence Graph connects credential records to actors, malware families, infrastructure, and campaigns in one unified model, combining exclusive underground sources with analyst curation for high‑fidelity context. This enables security teams to see the full picture of credential exposure, from initial theft through underground sale to potential exploitation.
Common use cases include detecting exposed employee and customer credentials, preventing account takeover attacks, monitoring executive and supplier identities, triaging suspicious login attempts, informing breach investigations, supporting vulnerability assessment, and enabling proactive password resets before credentials are exploited by attackers.
ZeroFox correlates each credential with metadata such as leak source, time of exposure, infostealer indicators, associated malware families, threat actor activity, and related campaigns. This context helps teams distinguish new breaches from recycled data, assess the severity of exposure, and choose the appropriate response based on actual risk rather than just the presence of leaked credentials.
Yes. ZeroFox integrates through APIs, webhooks, and pre-built connectors into SIEM platforms, SOAR tools, identity and access management systems, fraud detection platforms, and ITSM tools. Credential intelligence flows directly into your existing workflows for automated response and remediation.
Organizations can typically enable credential monitoring, configure watchlists for domains and VIP accounts, and begin receiving alerts within days. Initial setup involves defining monitoring scope, configuring alert thresholds, and establishing notification workflows. Organizations can then expand integrations and automation capabilities over time based on their security maturity and operational needs.
ZeroFox provides finished reports on credential‑theft campaigns, threat actor profiles focused on identity abuse operations, stealer malware family analyses, underground marketplace monitoring, breach database tracking, and industry‑specific exposure trends. These reports support both strategic planning and tactical response decisions, helping security teams understand the broader threat landscape affecting their organization.
