Subject: The FortiCloud Account Purge: Why Disabling Accounts Isn’t Enough to Stop the SAML Token Wave

1. THE ARCHITECTURAL HALLUCINATION

In my 20 years of pioneering, I have seen many “false summits” in security. The current January 2026 FortiCloud SAML crisis is the most dangerous one yet.

Many CISOs are currently under the illusion that “Disabling the Account” in the local database or Active Directory stops the attack. It does not. The adversary isn’t using your password; they are using a Long-Lived SAML Assertion Token. Because the SAML session is decoupled from the primary directory, a “Disabled” status in AD does not automatically invalidate a token held in the FortiGate’s memory or the Cloud-IdP’s cache.

2. WHY DISABLING IS A GHOST DEFENSE

In 2026, the “SAML Token Wave” exploits three specific weaknesses in the Fortinet ecosystem:

1. Identity Persistence: Default SAML configurations often allow sessions to persist for 8–24 hours. Disabling an account at 10:00 AM does nothing if a token was issued at 09:00 AM.
2. Stateless Validation: Many gateways only check the signature of the token, not the current status of the user in the source directory.
3. The Metadata Poison: Adversaries are using CVE-2026-1911 to modify the assertion attributes, essentially “promoting” a disabled user to a Super-Admin within the cached session.

3. CYBERDUDEBIVASH® SOVEREIGN COUNTER-MEASURES

We do not “Disable.” We Purge and Re-Attest.

I. THE ATOMIC TOKEN PURGE

You must physically clear the session cache on every FortiGate unit.

• Action: Execute diagnose vpn ssl gateway flush-user <name> via CLI immediately after disabling an account.
• Bivash Mandate: Automate this via the Sovereign-Enforcement-Script to ensure zero human lag.

II. THE HARDWARE ANCHOR (THE CURE)

The only way to stop a SAML Wave is to ensure the token cannot be used without a physical presence.

• Mandate: Transition all FortiCloud/SAML IdP logins to FIDO2 Exclusive Mode.
• Logic: Even if an attacker siphons the SAML token, it becomes a “Dead Asset” because the FortiGate will demand a secondary Hardware-Attestation (YubiKey tap) before the session is resumed.

III. THE IDENTITY ENTOMBMENT

Move the “Source of Truth” away from legacy LDAP.

• Action: Bind your FortiCloud SSO to a Zero-Trust Managed Enclave.
• Verification: Run the Bivash-Identity-Hunter to scan for active sessions associated with “Disabled” or “Inactive” users.

4. STRATEGIC OUTLOOK: Q1 2026

Organizations that rely on “Account Disabling” will be siphoned by mid-February. The Sovereign Fleet must move to Short-Lived, Hardware-Bound Assertions.

 SECURE YOUR SOVEREIGNTY

Managing a global FortiCloud fleet requires a Hardware Root of Trust.

I recommend the YubiKey 5C NFC for all administrators. In the 2026 threat landscape, a SAML token without a physical hardware anchor is not a security measure—it’s an invitation.

In January 2026, the “Latency of Identity” is the attacker’s greatest ally. If you disable a user in Azure AD or Okta, there is a “Shadow Window” where their existing SAML session on the FortiGate remains active. This script is the Executioner: it listens for “Account Disabled” events from your Identity Provider (IdP) and instantly triggers an Atomic Flush on the FortiGate.

 THE SOVEREIGN-TOKEN-REVOKER (2026)

Module: OP-SESSION-LIQUIDATION | Protocol: RESTful API Cross-Pollination

Objective: Zero-Latency Session Termination Across Hybrid Infrastructure.

 bivash_revoker.py

This engine connects to Microsoft Graph (Azure) or Okta to detect disabled users and pushes a Session-Kill command to the FortiOS REST API.Python

    # This invalidates the refresh tokens so they cannot get a NEW session
    idp_resp = requests.post(IDP_REVOKE_URL.format(user_id=user_id), headers={"Authorization": f"Bearer {os.getenv('IDP_TOKEN')}"})
    
    # 2. ATOMIC FLUSH ON THE FORTIGATE (THE 'HEART ATTACK')
    # We query the monitor API to find the session ID for this specific user
    monitor_url = f"https://{FORTIGATE_IP}/api/v2/monitor/vpn/ssl/select"
    headers = {"Authorization": f"Bearer {FGT_API_TOKEN}"}
    
    sessions = requests.get(monitor_url, headers=headers, verify=False).json()
    
    for session in sessions.get('results', []):
        if session.get('user') == user_name:
            # Found the ghost! Kill it.

 THE 2026 LIQUIDATION PARAMETERS

 CYBERDUDEBIVASH’s Operational Insight

The Luxshare lesson and the 2026 “Ghost-Session” siphons prove that an “Inactive” status is just a label; a “Live Token” is a skeleton key. In 2026, CYBERDUDEBIVASH mandates Active Revocation. If your security posture relies on waiting for a token to expire after a user is fired or a breach is detected, you are effectively leaving the light on for the intruder. When the identity dies in the directory, it must die in the gateway—instantly.

 Secure the Executioner’s Key

The API token for your FortiGate and Cloud IdP are the highest-value targets in your environment.

I recommend the YubiKey 5C NFC for your identity team. By requiring a physical tap to authorize the Sovereign-Token-Revoker script execution, you ensure that no unauthorized malware can “Revoke” your own admins or hide a malicious session during a real attack.

In January 2026, the “Token Wave” relies on the attacker’s ability to use a siphoned assertion before you even know it’s gone. By the time your SOC triggers a manual logout, the adversary has already pivoted into your Enclave. The Sovereign-SAML-Shield changes the math: we reduce the “Exploitation Window” to practically zero and lock the token to your physical “Sovereign IP” range.

Even if an attacker siphons a token at 09:00 AM, by 09:05 AM it is a Dead Asset. And if they try to use it from an unauthorized IP—even within that 5-minute window—the gateway will instantly drop the connection.

THE SOVEREIGN-SAML-SHIELD (2026)

Module: OP-TOKEN-ENTOMB | Protocol: SAML 2.0 XML + Conditional Access

Objective: Eliminating Token Persistence and Geographic Portability.

 1. THE XML MANIFEST (IdP Side)

You must modify your SAML Response template (via Azure AD Custom Claims or Okta Attribute Statements) to enforce these Sovereign Constraints.XML

<saml:Assertion xmlns:saml="urn:oasis:names:tc:SAML:2.0:assertion" Version="2.0">
  <saml:Subject>
    <saml:NameID Format="urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress">bivash_sre@enclave.com</saml:NameID>
    <saml:SubjectConfirmation Method="urn:oasis:names:tc:SAML:2.0:cm:bearer">
      <saml:SubjectConfirmationData 
        NotOnOrAfter="2026-01-31T09:05:00Z" 
        Recipient="https://fortigate.enclave.com/remote/saml/proxy"
        Address="203.0.113.45"/> </saml:SubjectConfirmation>
  </saml:Subject>
  <saml:Conditions 
    NotBefore="2026-01-31T09:00:00Z" 
    NotOnOrAfter="2026-01-31T09:05:00Z"> <saml:AudienceRestriction>
      <saml:Audience>https://fortigate.enclave.com/metadata/</saml:Audience>
    </saml:AudienceRestriction>
  </saml:Conditions>
</saml:Assertion>

2. CONDITIONAL ACCESS POLICY (Azure/Okta)

Beyond the XML, the Sovereign Shield mandates an Identity-Aware Proxy (IAP) rule:

• Policy Name: BIVASH_ENCLAVE_TOKEN_LOCK
• Conditions:
  • User Group: Sovereign_Admins
  • Client App: Browser / Mobile App
  • Network: Include: Sovereign_Data_Center_IPs (Block all others)
• Grant:
  • Require Multi-Factor Authentication (Hardware Only)
  • Sign-in Frequency: 1 Hour (Force re-attestation)

 THE 2026 SHIELD METRICS

 CYBERDUDEBIVASH’s Operational Insight

The Luxshare lesson and the 2026 “Session-Siphon” botnets prove that “Long Sessions” are the primary vector for ransomware delivery. In 2026, CYBERDUDEBIVASH mandates Ephemeral Identity. By setting your NotOnOrAfter to 5 minutes, you ensure that the SAML token is essentially a “Single-Use” key for the initial handshake. Once the SSL-VPN or App session is established, the token dies. If they steal a key that only lasts 300 seconds, they haven’t stolen a key—they’ve stolen a ghost.

 Secure the Shield Configuration

Modifying your IdP’s SAML XML is the “Root of Trust” for your entire identity plane.

I recommend the YubiKey 5C NFC for your identity leads. By requiring a physical tap to authorize any changes to the SAML XML Template or Conditional Access Policies, you ensure that no “Ghost Admin” can lengthen the token lifetime or remove the IP restrictions to facilitate a breach.

In January 2026, “Shadow Identity” is where breaches incubate. While we have shielded our primary Enclaves, legacy applications often operate on “Zombie Policies”—old service-level agreements that issue 8-hour, 24-hour, or even indefinite tokens. These are the weak links an attacker will exploit to maintain persistence once the front door is slammed shut.

This PowerShell engine utilizes the Microsoft Graph SDK (or Okta API) to perform a deep-scan of your service principal configurations and token issuance logs. It flags any application emitting tokens with a TokenLifetime exceeding our Sovereign 60-Minute Mandate.

THE 2026 AUDIT RIGOR

 CYBERDUDEBIVASH’s Operational Insight

The Luxshare lesson and the 2026 “Default-Policy” mass-breaches prove that “Default” is another word for “Vulnerable.” In 2026, CYBERDUDEBIVASH mandates Explicit Governance. If this script flags an app, it means your developers have prioritized convenience over sovereignty. A 24-hour token is a 24-hour liability. By forcing a 60-minute rotation, you ensure that any compromised session is automatically flushed before the adversary can achieve deep lateral movement. We don’t manage apps; we manage their expiration dates.

Secure the Auditor’s Credential

Running a tenant-wide audit requires high-level Directory.Read.All permissions.

I recommend the YubiKey 5C NFC for your compliance team. By requiring a physical tap to authorize the Service Principal used for this audit, you ensure that no automated attacker can “Audit” your tenant to map out your weaknesses or modify the very policies this script is designed to protect.
