Business Challenge
The client operates high-volume financial services where stolen credentials, leaked PII, or early chatter about fraud on the dark web can translate directly into financial loss and severe reputational damage. Leadership wanted continuous visibility into underground activity relevant to their brand, customers, employees, and third-party vendors — plus rapid, actionable response when threats surfaced.
Key concerns included:
● Credential dumps and buyer-seller activity involving customer or employee data
● Early indicators of targeted fraud or account takeover campaigns
● Brand impersonation and fraudulent merchant listings
● Potential sale or leak of proprietary code, API keys, or third-party vendor access

Approach & Methodology
We implemented a 24/7 Dark Web Monitoring & Threat Intelligence program structured around detection, enrichment, and response:
Target & Data Mapping
Built a watchlist: brand variants, employee emails, executive aliases, domains, API keys, product names, vendor identifiers, and payment instrument patterns.
Continuous Collection
Crawled clear-web, deep-web forums, paste sites, marketplaces, and encrypted channels using automated collectors and human analysts. Ingested partner dark-web feeds and commercial OSINT sources.
Enrichment & Prioritization
Correlated artifacts with internal telemetry (SIEM, fraud logs) and contextual indicators (geography, timestamps, actor reputation). Applied risk scoring to filter false positives and prioritize high-impact items.
Alerting & Response Playbooks
Triaged findings and delivered high-priority alerts to the SOC and Fraud teams (phone/Slack/secure portal). Orchestrated remediation: credential resets, MFA enforcement, takedowns, vendor notifications, legal escalation.
Takedown & Defensive Actions
Coordinated with hosting providers, marketplace admins, and partners to remove listings and disrupt seller operations. Implemented short-term mitigations (WAF rules, IP blocks, fraud-rule updates).
Reporting & Intelligence Handoff
Produced weekly intelligence briefs and a monthly executive summary mapping risk trends and recommended strategic controls.
Key Findings
● Credential Dumps: Multiple batches containing customer email:password pairs and ~1,800 employee credentials surfaced across paste sites and a private forum. Many were recycled passwords.
● Fraud Campaign Planning: A closed forum thread described a planned account-takeover campaign timing aligned with a product launch window.
● Exposed Secrets: A contractor’s misconfigured S3 snapshot contained API keys and a small set of hashed but weakly salted credentials.
● Brand Abuse: Fake merchant pages and phishing kits using the client’s brand appeared on a marketplace, targeting payments via spoofed URLs.
● Ransomware Mention: An actor discussed selling a production database (unverified) — requiring urgent verification and containment.
