Detect exposed credentials before attackers weaponize them.
Continuously monitor the dark web, breach databases, stealer log marketplaces, Telegram channels, and paste sites for credentials linked to your organization. Know about exposures in minutes, not months.
Credentials are the #1 attack vector
Every day, millions of credentials are harvested by infostealer malware, leaked in data breaches, and traded on dark web marketplaces. When your employees' corporate credentials end up in a stealer log or breach compilation, attackers don't wait. They test those credentials within hours, launching credential stuffing attacks, gaining initial access to your network, and pivoting to higher-value targets.
Without continuous monitoring, most organizations only learn about credential exposures after the damage is done. intelsieve closes that gap by detecting exposed credentials across six major source categories and alerting your team before attackers have time to act.
Six source categories. One unified view.
We monitor the full credential exposure landscape so you don't have to juggle multiple tools or manual processes.
Stealer Log Marketplaces
Monitor Russian Market, Genesis Market, and other infostealer log shops where credentials harvested by RedLine, Raccoon, Vidar, and other stealer malware are sold in bulk. We parse raw stealer logs to extract your domain-specific credentials before buyers weaponize them.
Breach Database Compilations
Continuously ingest and cross-reference credentials from known data breaches, combo lists, and compilation dumps like COMB and AntiPublic. Our deduplication engine ensures you only see net-new exposures relevant to your organization.
Dark Web Forums
Automated crawlers and human analysts monitor closed-access dark web forums where threat actors trade, sell, and leak credentials. We cover major English and Russian-language forums where corporate credential dumps frequently surface.
Telegram Channels
Track thousands of Telegram channels and groups where threat actors distribute stealer logs, combo lists, and freshly breached credentials. Our bot network monitors channels in real time and extracts domain-matched credentials within minutes of posting.
Paste Sites
Scan Pastebin, Ghostbin, PrivateBin, and dozens of alternative paste platforms where credentials are frequently dumped publicly or semi-publicly. Our scanners check new pastes continuously, catching exposed credentials before they are indexed by search engines.
Code Repositories
Detect credentials accidentally committed to public GitHub, GitLab, and Bitbucket repositories. We scan commit histories, gists, snippets, and CI/CD configuration files for API keys, passwords, tokens, and connection strings linked to your domains.
How credential detection works
From configuration to actionable alerts in three straightforward steps.
Configure Domains & Keywords
Add your corporate domains, email patterns, brand keywords, and specific employee emails you want to monitor. Our system automatically expands your watchlist to cover subdomains, legacy domains, and common misspellings attackers exploit.
Cross-Source Monitoring
Our collection engine continuously scans stealer log marketplaces, breach compilations, dark web forums, Telegram channels, paste sites, and code repositories. New sources are matched against your configured watchlist in near real time.
Prioritized Alerts with Remediation Guidance
Exposed credentials are deduplicated, enriched with context (source, timestamp, password type, associated malware family), and ranked by risk. Each alert includes specific remediation steps so your team can act immediately.
Why speed matters in credential exposure
The window between credential exposure and exploitation is shrinking. Threat actors automate credential testing at scale, turning stolen passwords into unauthorized access within hours.

The credential weaponization timeline
Research from multiple threat intelligence sources shows a consistent pattern: once credentials are harvested by infostealer malware, they typically appear on stealer log marketplaces within 24-48 hours. Buyers then test these credentials against corporate VPNs, email systems, and cloud services within 4-6 hours of purchase.
For credentials leaked in data breaches, the timeline varies. Some breaches are sold privately for weeks before becoming widely available, while others are dumped publicly with no warning. In either case, early detection is the only reliable defense. Organizations that detect exposed credentials within the first hour reduce their risk of account takeover by over 90% compared to those relying on periodic breach checks.
intelsieve is designed for this reality. Our infrastructure prioritizes speed at every stage: real-time source monitoring, sub-minute matching, and alert delivery in under 15 minutes. When credentials are exposed, every minute counts.
Response workflow when credentials are found
A structured four-phase process ensures every exposed credential is handled consistently and thoroughly.
Instant Notification
The moment exposed credentials matching your domains are detected, alerts are pushed to your configured channels: email, Slack, Microsoft Teams, webhooks, or SIEM. Each alert contains the affected email, source, exposure date, and severity rating.
Contextual Validation
Determine whether the exposure is from a fresh breach, a recycled combo list, or active stealer malware. intelsieve enriches each finding with source attribution, password age estimation, and whether the credential appears in multiple sources, helping you separate noise from genuine threats.
Forced Credential Rotation
For confirmed active exposures, trigger password resets through your identity provider. intelsieve provides integration guides for Okta, Azure AD, Google Workspace, and other IdPs to streamline bulk credential rotation when large-scale exposures are detected.
Continuous Post-Incident Tracking
After remediation, the affected credentials are flagged for heightened monitoring. If the same credentials resurface in a new source, or if the associated accounts show signs of unauthorized access, you are alerted immediately to prevent re-compromise.
Each phase generates a timestamped audit trail for compliance reporting. intelsieve integrates with Splunk, Elastic, and other SIEM platforms to ensure credential exposure events are part of your broader security event management pipeline.
Built for security teams who need to move fast
Whether you are a lean security team or a mature SOC, credential exposure detection integrates into your existing workflows.

Frequently asked questions
Common questions about credential exposure detection and how intelsieve helps protect your organization.
What types of credentials does intelsieve detect?
intelsieve detects email and password pairs, API keys, authentication tokens, session cookies, SSH keys, database connection strings, and cloud access keys. We monitor for credentials exposed through data breaches, stealer malware (RedLine, Raccoon, Vidar, Lumma, and others), accidental code commits, paste site dumps, and dark web marketplace listings. Our detection covers both plaintext and hashed credentials, with automatic identification of hash types and weak password indicators.
How quickly are credential exposures detected?
Most credential exposures are detected and reported within 15 minutes of appearing in our monitored sources. For stealer log marketplaces and Telegram channels, detection is often faster because we monitor these sources in near real time. Breach database compilations may take slightly longer depending on when they surface, but our collection infrastructure ensures we ingest new dumps within hours of their initial distribution in threat actor communities.
How is this different from Have I Been Pwned or similar free tools?
Free breach notification services only cover publicly disclosed data breaches and typically alert you days or weeks after the data becomes available. intelsieve monitors the full credential exposure lifecycle: stealer log marketplaces where fresh credentials are sold daily, private Telegram channels, closed dark web forums, and paste sites. We also provide organizational-level monitoring (all employees under your domains), deduplication, source attribution, password age estimation, and actionable remediation guidance for each exposure. This proactive approach catches credentials that free tools will never see.
Can I monitor credentials for specific employees or VIP accounts?
Yes. In addition to domain-wide monitoring, you can add specific email addresses, usernames, or keyword patterns to your watchlist for priority alerting. This is commonly used to monitor C-suite executives, IT administrators, and employees with access to sensitive systems. VIP accounts receive elevated alert priority and can be routed to dedicated notification channels for faster response.
What should I do when exposed credentials are found?
When intelsieve detects exposed credentials, each alert includes a recommended response playbook. The immediate steps are: (1) force a password reset for the affected account, (2) review recent login activity for signs of unauthorized access, (3) check whether the same password was reused across other services, and (4) enable or enforce multi-factor authentication if not already active. For stealer log exposures, you should also check the affected endpoint for active malware since infostealer infections indicate the device itself is compromised.
Does intelsieve store the actual exposed passwords?
intelsieve does not store plaintext passwords from detected exposures. When credentials are found, we store a cryptographic hash of the password for deduplication and comparison purposes, along with metadata such as the source, date of exposure, and associated email. This approach lets us identify when the same credential appears in multiple sources and determine whether a new exposure contains a previously seen or a different password, all without retaining sensitive plaintext data in our systems.
