Get-Credential is a PowerShell cmdlet that prompts a user for credentials and returns them as a credential object. It is commonly used for legitimate authentication prompts, but attackers can abuse it for social engineering or to capture entered secrets. Monitor for unexpected prompts and scripts that request credentials.
What Get-Credential Does in PowerShell
Get-Credential is a PowerShell prompt that collects a username and password, then returns a credential object for later use. It is legitimate in administrative scripts, but its interactive prompt makes it easy to abuse as a trust signal.
Because the cmdlet returns a structured credential object, it often sits at the boundary between a harmless workflow and a sensitive secret-handling event. That matters whenever scripts run in admin sessions, automation wrappers, remote management tools, or helpdesk-runbooks where users may be conditioned to “just enter the password.”
Why It Matters in Security Operations
The security significance of Get-Credential is not the cmdlet itself, but the fact that it can normalize secret entry inside a script or console session. A prompt that appears at the wrong time, in the wrong context, or from the wrong script can be used to solicit live credentials without the user noticing the difference.
That risk is strongest when operators rely on visual trust alone. A malicious script can invoke the same prompt style a legitimate admin script uses, which means users may disclose passwords to code they would otherwise reject. For broader PowerShell hardening, PowerShell Security Guide is the most direct companion reference because it covers the script abuse patterns that make this cmdlet dangerous.
How It Is Commonly Abused
Attackers use Get-Credential as a social-engineering primitive: the prompt looks normal, the script appears administrative, and the user believes the password is needed for a routine task. In practice, this can capture credentials that are then reused immediately or stored for later abuse.
The cmdlet can also become part of a broader secret-theft chain. If a user enters a password into a malicious session, that secret may unlock email, VPN, remote management, cloud consoles, or other systems that were never meant to be exposed through the original script. For the downstream secret-handling problem, the Secret Sprawl Challenge is useful because it frames how credentials leak, spread, and become difficult to govern once they leave intended storage.
Safer Use and Detection
Legitimate use is still appropriate when a script truly needs interactive authentication, but teams should treat every unexpected credential prompt as a security event worth validating. The question is not whether PowerShell can prompt, but whether the prompt belongs in that workflow, on that host, and at that moment.
Monitoring should focus on unexpected prompt behavior, unusual parent processes, scripts that request credentials without a clear business reason, and sequences where a prompt precedes remote access or privilege-sensitive actions. Credential handling discipline matters here as well, especially when long-lived secrets are being substituted for interactive sign-in. Secrets Management Guide is a strong reference for reducing that exposure by moving away from ad hoc secret entry where possible.
Practical Security Implications
Get-Credential is best understood as a control boundary, not just a convenience cmdlet. When it appears in a script, it can indicate legitimate authentication, but it can also mask credential collection, unsafe secret reuse, or a weak assumption that the user will recognize fraud by sight alone.
For environments that rely heavily on PowerShell administration, the safer pattern is to minimise surprise prompts, restrict who can run high-trust scripts, and review any workflow that asks for a password when a stronger authentication or delegated-access model would do instead. OWASP Non-Human Identity Top 10 is also relevant when script-driven access depends on credentials that should be scoped, rotated, and governed rather than repeatedly typed by humans.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
MITRE ATT&CK addresses the attack and risk surface, while NIST SP 800-53 Rev 5, CIS Controls v8 and OWASP ASVS set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST SP 800-53 Rev 5 | IA-5 — Authenticator Management | Get-Credential exposes passwords that should be governed as authenticators. |
| AU-6 — Audit Record Review, Analysis, and Reporting | Unexpected credential prompts need review and correlation with script activity. | |
| Recommendation — Manage authenticator lifecycle so interactive prompts do not become uncontrolled secret collection points. Review logs for unexpected credential prompts and correlate them with script execution and remote access. | ||
| CIS Controls v8 | CIS-5 — Account Management | Credential prompts relate to account use, authorization, and access governance. |
| Recommendation — Restrict and monitor account use so prompted credentials are only entered where the workflow is trusted. | ||
| OWASP ASVS | V6 — Authentication | The cmdlet is a user-facing authentication prompt that can collect live credentials. |
| Recommendation — Verify that authentication prompts cannot be spoofed or embedded into untrusted script flows. | ||
| MITRE ATT&CK | T1056.001 — Keylogging | Abuse of credential-entry prompts overlaps with credential capture techniques. |
| Recommendation — Hunt for credential capture behavior around prompts and remote execution paths. | ||
