Medusa

Medusa is a network authentication testing tool. Public practical guidance must restrict use to a loopback or isolated lab service with one synthetic account, a tiny attempt budget, lockout monitoring, and immediate teardown.

Start safely and get useful results

Best for

  • • Authentication-control lab testing
  • • Lockout and alert validation

Not for

  • • Password spraying
  • • Credential stuffing or production testing

Before you run anything

  • • Document the authorized target, time window, success criteria, data-handling rules, and a named stop contact before you begin.
  • • Confirm the installed version with the tool’s version or help command, then compare its documented behavior with the linked upstream project before relying on any option.

Practical workflows

Beginner

Inspect available modules without running an attack

Scenario: Plan a local mock-service test.

medusa -h

Review installed syntax and supported modules before defining a minimal lab test.

Expected use: The authorization should state a maximum attempt count and stop condition.

Intermediate

Validate rate-limit and lockout telemetry safely

Scenario: A disposable local service has one synthetic account.

Run only against a loopback or isolated lab service with a tiny pre-agreed test set.

Stop on the first lockout, alert, or unexpected side effect; collect server logs.

Expected use: The desired result is control enforcement and observable telemetry, not account access.

Interpret results like an analyst

  • • An accepted login in a lab validates a test account path, not a production weakness.
  • • Assess lockout, throttling, MFA, alerting, and recovery behavior together.

Common mistakes and operating tips

Avoid

  • • Using real usernames or password lists.
  • • Increasing parallelism instead of measuring one controlled control response.

Operational discipline

  • • Treat command output as evidence, not a conclusion: retain the command, version, scope, timestamp, and a redacted result in the engagement record.
  • • Start with the smallest safe scope, validate expected behavior in a lab or pilot, then expand only when the authorization and monitoring plan support it.

Verify against the current upstream

Tool behavior and release syntax can change. Treat this guide as practical operating context, then verify version-specific details against the upstream project before an assessment.
