🔐 CloudCSF – Day 30 | Zombie Permissions: The Silent Access Risk
🎯 Security Control #30: Audit Inactive but Privileged Accounts
📊 Risk Level: CRITICAL | Audit Time: 20 mins | ROI: Massive
💀 What Are Zombie Permissions?
These are user or service accounts that still hold powerful roles (admin, owner, superuser) — but haven’t logged in or been used in months.
They are silent, invisible, and dangerously alive… until attackers find them.
📉 Real Breach Example:
A retail giant suffered a data breach when a long-departed vendor account with “read-all” access to cloud storage was token-stolen and abused, resulting in 5 million leaked customer records.
✅ Actionable Steps Today:
- Export all IAM users with last login > 90 days
- Check for roles like Owner, Admin, Root, Storage Full Access
- Deactivate or delete if unapproved
- Rotate credentials for those still valid
- Document justification for keeping privileged access
