Credential Dumping
Pronunciation: kruh-DEN-shul DUMP-ing
Definition
Credential Dumping is the extraction of passwords, hashes, tokens, tickets, keys, or other authentication material from operating systems, memory, browsers, applications, or credential stores.
Overview
How it works and why it matters
Credential dumping is the unauthorized extraction of passwords, tokens, session secrets or authentication material from a device or service. Attackers may target memory, browser stores, configuration files or compromised endpoints. A stolen API key or session token can allow actions without knowing the user’s password. Effective defenses include hardening endpoints, least privilege, short-lived credentials, monitored access, strong authentication and fast rotation after suspected compromise.
Technical context
It differs from ordinary credential theft through phishing because the attacker retrieves credentials from a compromised system or repository.
Logs concerning the Credential Dumping context and extraction of passwords, hashes, and tokens should support investigation without exposing reusable secrets or unnecessary personal data.
Practical checks
Disable long-lived tokens in local configuration and development logs, and inspect endpoints for unauthorized secret-access processes. Require minimal API scopes, secure secret storage and short rotation intervals where feasible. Following suspected exposure, revoke active sessions, rotate downstream keys and review recent money-moving operations for abuse.

Example
An attacker compromises a finance laptop and extracts a stored payout API token. The thief attempts to create unauthorized withdrawals. Narrow token permissions, destination allowlists and independent payout approval reduce the damage even if the credential is exposed.
Comparison
Credential dumping obtains existing secrets, whereas guessing or phishing acquires access through other methods. Multifactor authentication does not always stop abuse of a stolen authenticated session or API token.
Key Takeaway
Protect and scope the credentials already present on devices and servers.
