When an employee device is in an infostealer log, find it before the attacker uses it.
Infostealer malware drops snapshots of compromised devices into criminal markets: every browser-saved password, every active session cookie, every autofilled form field. If an employee's device gets infected, the credentials they used at work are part of the package. Deepinfo monitors infostealer log dumps continuously for any indicator that ties back to your organization.
Continuous monitoring of infostealer log markets.
When infostealer log packages surface, typically in dark-web markets and Telegram channels, Deepinfo ingests them, indexes the credentials and identifiers inside, and matches against your corporate domains, hostnames, and any other organizational identifiers you've configured.
Each detection includes the source dump, the device fingerprint where available, the timestamp of compromise, and an inventory of credentials exposed: browser-saved passwords (which sites, which accounts), active session cookies, form autofill data. Your IR team has what's needed to invalidate sessions, force credential resets, and trace device ownership.
Three signals that tie a compromised device to your organization.
Infostealer dumps don't arrive labeled with an employer. Three matching signals link a captured device back to your environment so the right alerts fire.
Corporate domain in saved credentials.
Most infostealer logs include a list of websites the user had passwords saved for. If your corporate SSO endpoint, internal portal, or work email shows up in that list, the device was used to access your environment.
Corporate hostname in browsing history.
Internal hostnames, VPN endpoints, and corporate-application URLs appearing in the captured browsing history or session list.
Email pattern matching.
Email addresses on your corporate domains used as login identifiers in saved credentials, even if the credential itself doesn't match your SSO endpoint directly.
Examples of what an infostealer alert actually contains.
Source dump
Dump name, the market it surfaced in, and the date posted, so analysts can pivot on the source.
Compromise timestamp
When the device was infected, helping triage urgency relative to recent employee activity.
Saved credentials inventory
Full list of saved credentials with corporate-domain matches highlighted.
Active session cookies
Session cookies for corporate applications. High-priority because they bypass MFA and can grant immediate access.
Browsing history
Corporate URLs accessed from the compromised device, helping scope which systems were touched.
Form autofill data
Names, emails, and other PII tied to the user, useful for identifying device ownership.
Device fingerprint
OS, browser, language, timezone where available, supporting identification of the affected device.
Device monitoring catches what email-only monitoring misses.
Employee Email Breach Monitoring catches credentials exposed in service breaches. Compromised Employee Device Monitoring catches credentials exposed when the employee's machine itself was compromised. Both are necessary; neither is sufficient alone. Together with the Data Breach Index and Threat Actor Intelligence, they cover the full credential-exposure surface.
“Infostealer logs are now part of our weekly review. When an employee device shows up, we revoke active sessions and rotate credentials before we wait for the EDR to flag anything internal.”
