What it does

Performing Service Account Audit is an agent skill from mukul975/Anthropic-Cybersecurity-Skills. Audit service accounts across enterprise infrastructure to identify orphaned, over-privileged, and non-compliant accounts. This skill covers discovery of service accounts in Active Directory, cloud pl

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files, including scripts, reference files and assets (for example `assets/template.md`, `references/api-reference.md` and `references/standards.md`).

It sits in Security, covering Red teaming and adversary simulation. The repository describes itself as: 817 structured cybersecurity skills for AI agents · Mapped to 6 frameworks: MITRE ATT&CK, NIST CSF 2.0, MITRE ATLAS, D3FEND, NIST AI RMF & MITRE F3 (Fight Fraud) · agentskills.io…. The licence is Apache-2.0.

What it can do on your machine

Read from SKILL.md and the folder at commit 54a7988. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 2 files in scripts/ (Python), which the agent can run.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Performing Service Account Audit loads about 1.4k tokens when it runs, and up to ~2.4k if it reads all its reference files. Until then it costs about 58 tokens; SKILL.md has 579 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~58
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Performing Service Account Audit

Overview

Audit service accounts across enterprise infrastructure to identify orphaned, over-privileged, and non-compliant accounts. This skill covers discovery of service accounts in Active Directory, cloud platforms, databases, and applications, assessing privilege levels, identifying missing owners, and enforcing lifecycle policies.

When to Use

  • When conducting security assessments that involve performing service account audit
  • When following incident response procedures for related security events
  • When performing scheduled security testing or auditing activities
  • When validating security controls through hands-on testing

Prerequisites

  • Familiarity with identity access management concepts and tools
  • Access to a test or lab environment for safe execution
  • Python 3.8+ with required dependencies installed
  • Appropriate authorization for any testing activities

Objectives

  • Discover all service accounts across AD, cloud, databases, and applications
  • Identify orphaned accounts with no valid owner or associated application
  • Assess privilege levels and flag over-privileged service accounts
  • Check for non-rotating passwords and weak authentication
  • Map service account dependencies for safe remediation
  • Generate compliance reports for SOX, PCI DSS, and HIPAA audits

Key Concepts

Service Account Types
  1. AD Service Accounts: Windows services, scheduled tasks, IIS app pools
  2. Managed Service Accounts (gMSA): AD-managed automatic password rotation
  3. Cloud IAM Service Accounts: AWS IAM roles/users, Azure service principals, GCP service accounts
  4. Database Service Accounts: Application connection accounts, replication accounts
  5. Application Service Accounts: API keys, bot accounts, integration accounts
Audit Dimensions
  • Ownership: Who is responsible for this account?
  • Purpose: What application/service uses this account?
  • Privileges: What permissions does this account have?
  • Authentication: How does this account authenticate (password, key, certificate)?
  • Rotation: When was the credential last changed?
  • Activity: When was this account last used?

Workflow

Step 1: Discovery - Active Directory
  1. Query AD for all service accounts (filter by description, OU, naming convention)
  2. Identify accounts with ServicePrincipalName set
  3. List accounts in privileged groups (Domain Admins, Enterprise Admins)
  4. Check for gMSA vs traditional service accounts
  5. Identify accounts with PasswordNeverExpires flag
Step 2: Discovery - Cloud Platforms
  • AWS: List IAM users with access keys, check last used date, identify unused roles
  • Azure: Enumerate service principals, app registrations, managed identities
  • GCP: List service accounts, check key age, identify unused permissions
Show full SKILL.md (226 more words)Show less
Step 3: Assessment
  • Flag accounts with admin/privileged group membership
  • Check password age against rotation policy (90 days max)
  • Identify accounts with no login activity in 90+ days
  • Verify account ownership against CMDB/asset inventory
  • Check for shared credentials (same password hash across accounts)
Step 4: Risk Classification
  • Critical: Domain/cloud admin privileges, no password rotation
  • High: Access to sensitive data, no identified owner
  • Medium: Standard service permissions, password older than 90 days
  • Low: Read-only access, managed credentials (gMSA, managed identity)
Step 5: Remediation
  • Disable orphaned accounts after validation with application teams
  • Convert traditional service accounts to gMSA where possible
  • Rotate credentials older than policy threshold
  • Reduce privileges to minimum required
  • Assign owners and document dependencies

Account ManagementAC-2Service account lifecycle
Account ReviewAC-2(3)Periodic review of accounts

Audit ReviewAU-6Review service account activity

Common Pitfalls

  • Disabling service accounts without verifying application dependencies first
  • Not discovering service accounts outside of Active Directory
  • Missing cloud service principals and managed identities
  • Not checking for interactive logon rights on service accounts
  • Failing to document dependencies before remediation

Verification

  • Service accounts inventoried across all platforms
  • Each account has assigned owner
  • Privileged service accounts documented with justification
  • Password rotation compliance checked
  • Orphaned accounts flagged for remediation
  • gMSA migration candidates identified
  • Compliance report generated
