When customer credentials surface in dumps, protect the accounts before the takeover.
Account takeover starts with a credential surfacing somewhere it shouldn't: a breach dump, an infostealer log, a credential-stuffing list. Compromised Client Credential Monitoring watches those sources continuously for credentials that match your customer-facing platform, so your fraud and identity teams can act before the attacker logs in.
Customer credential exposure, surfaced as it becomes available.
Specify the customer-facing endpoints and patterns to monitor: your login domain, your account portal, any pattern that identifies a customer credential at your platform. Deepinfo monitors breach corpora and infostealer log dumps continuously for matching credentials.
Each detection includes the customer identifier, the source of the exposure, the credential type, and the timestamp. Routing goes directly to fraud-prevention workflows, account-protection systems, or your customer-communications layer (depending on your incident-response pattern).
Three monitoring inputs, one alert stream.
Customer-credential exposure surfaces from three different streams. All three feed the same alert pipeline, scoped to credentials matching your customer-facing platform.
Breach corpora.
The Data Breach Index covers breach datasets indexed continuously. Customer credentials matching your patterns get flagged on each new breach.
Infostealer dumps.
Infostealer logs containing browser-saved credentials for your customer-facing platform get matched and surfaced. These are particularly dangerous: they include active session cookies that bypass MFA.
Credential-stuffing lists.
Lists circulating in dark-web markets explicitly assembled for credential-stuffing attacks. Detection here usually precedes a credential-stuffing campaign by hours to days.
Examples of what each customer-credential alert contains.
Customer identifier
Email, username, or other login identifier on your platform.
Source
Where the credential surfaced: breach name, infostealer dump, or credential-stuffing list.
Credential type
Plaintext, hash, or session cookie, with priority routing for cookies that bypass MFA.
Hash type
For hashed credentials: bcrypt, MD5, SHA-1, and others, so account-protection workflows know what was exposed.
Plaintext password
Where the source exposed it (or where a hash has been cracked), supporting direct verification.
Repeat indicator
Prior appearances of the same identifier, with count and timeline for risk scoring.
Customer credential monitoring complements employee credential monitoring.
This sub-feature handles customer-facing exposure (account takeover risk for your users); Employee Email Breach Monitoring and Compromised Employee Device Monitoring handle workforce exposure (compromise of your environment). Both feed the same intelligence pipeline. For payment-specific exposure, Compromised Payment Credential Monitoring is the dedicated capability.
“Credential-stuffing attacks against our customer accounts dropped substantially once we started catching exposed credentials within hours of them surfacing. We force-reset before the attacker has time to test the dump.”
