“The Credential Time Bomb: When Secrets Live Longer Than People”

🔍 Introduction — Credentials Don’t Retire Themselves

Organizations terminate employees in minutes.
But credentials often survive for years.

Passwords, API keys, tokens, certificates, SSH keys —
they quietly outlive:

  • Employees
  • Vendors
  • Projects
  • Systems

And attackers don’t guess credentials anymore.
They wait for forgotten ones.

In 2025, the most abused access paths weren’t zero-days —
they were old secrets still trusted.


⚠️ 2025 Breach Pattern — Stale Credential Abuse

CISORadar Credential Risk Signals (2024–2025):

Credential TypeAssumptionExploited Reality
API Keys“Internal use only”Never rotated
Service Account Passwords“Non-human”Hard-coded
Cloud Access Keys“Temporary”Years old
SSH Keys“Low risk”Shared across teams
Certificates“Auto-renewed”Expired & bypassed

💬 CISORadar Insight:

“Attackers don’t break authentication —
they inherit it.”

💬 CISORadar Observation:

“We rotate people faster than we rotate secrets.”


🧠 CISORadar Control Test of the Week

Control Reference: ISO 27001 A.5.17 / NIST IA-5
Objective: Eliminate credential persistence risk.

🔍 Test Steps

1️⃣ Inventory all secrets (passwords, tokens, keys, certs)
2️⃣ Identify credentials older than 90 / 180 days
3️⃣ Detect hard-coded or shared secrets
4️⃣ Validate vault usage and access logs
5️⃣ Confirm ownership and rotation cadence
6️⃣ Calculate Credential Exposure Index (CEI)

✅ Expected Outcome

  • All secrets inventoried and owned
  • No long-lived or shared credentials
  • Automated rotation enforced
  • Credential risk visible to leadership

Suggested Tools:

🧨 Example Case — “The Token That Outlived the Company”

Incident:
A fintech breach traced to an API token created during a PoC.

What failed:

  • Token never expired
  • No owner
  • Full production scope

Impact:

  • 18 months of silent access
  • ₹520 Cr regulatory exposure

Lesson:

“If a credential has no expiry, it has infinite risk.”

🧭 Leadership Takeaway

Boards must stop asking:
“Do we have MFA?”

And start asking:
“How long do our secrets live?”
“Who owns every credential?”
“Which secrets could breach us tomorrow?”

Because in modern breaches:

Credentials don’t get stolen.
They get forgotten.

CISORadar turns secret sprawl into governed credential trust.
