The DevOps vs. Forensics Mindset: Tracing Unauthorized kubectl Access on EKS

Frank Osasere Idugboe — Sat, 31 Jan 2026 10:09:14 +0000

Most days, I live in the world of high availability, pipelines, and speed. But lately, I’ve been wearing two caps: one as a Senior DevOps Engineer keeping production alive, and the other as a Master’s student in Digital Forensic Science at UNIFESSPA (Marabá, Brazil).

In DevOps, we are trained to restore service at all costs. If a server acts up, we kill it and replace it. But the Forensics side of my brain has started to whisper:

"Wait. If you delete that server now, you delete the evidence forever."

This is the story of a real incident on an AWS EKS cluster where those two worlds collided.

The Alert: "Someone is in the house"

Date: 2026-01-20 | Region: us-east-1

It started with a CloudWatch alert. The system detected unusual commands in our payment-processing namespace.

For the non-experts: In Kubernetes, a command called kubectl exec allows you to log directly into a running container. In a production environment, this is rarely necessary. It is like a bank teller bypassing the counter and walking directly into the vault.

Even worse, the intruder was listing Kubernetes Secrets, essentially reading the passwords for our databases.

My DevOps instinct kicked in: "Stop the bleeding. Kill the pods. Rotate the keys."

But my Forensic training stopped me. If I nuked the environment, I would never find out how they got in. The attacker would just come back tomorrow. I had to investigate while the trail was still warm.

Step 1: Freezing the Crime Scene

If a burglar breaks into your house, you don't start cleaning up the broken glass immediately. You take photos.

Before I changed a single firewall rule or blocked a user, I captured the cluster's current reality. I needed to see exactly what was running before the attacker (or our auto-scaling tools) changed it.

# I saved the timeline of events to a file
kubectl get events -A --sort-by=.lastTimestamp > incident_timeline.txt

# I took a snapshot of every running pod
kubectl get pods -o wide -A > pod_snapshot.txt

# I checked if they gave themselves permanent admin rights (Backdoors)
kubectl get clusterrolebindings -o yaml > crb_snapshot.yaml

Killing a pod is easy. Explaining to your CTO how the attacker got there, after you deleted the evidence, is impossible.

Step 2: Dusting for Fingerprints (The Logs)

Kubernetes activity is just API traffic. Every time you type a command, the server writes it down. Since we had EKS Control Plane Logging enabled, every command left a fingerprint in AWS CloudWatch.

I didn't need a fancy security tool. I just needed to ask the logs the right question. I used CloudWatch Logs Insights to look for the "connect" command (which is how K8s logs an exec attempt).

SQL
fields @timestamp, @message
| parse @message '"username":"*"' as user
| parse @message '"verb":"*"' as action
| parse @message '"objectRef":{"resource":"*"' as res
| filter action in ["connect", "create", "patch", "delete"] 
| filter res in ["pods", "secrets", "clusterrolebindings"]
| filter user not like "system:node"
| sort @timestamp desc

The results were clear. An IAM role was being used to open these connections: arn:aws:sts::123456789012:assumed-role/ReadOnly-Developer/Session-XYZ

Step 3: Finding the Person Behind the Role

This is where it gets tricky. Kubernetes knew which key was used (the IAM Role), but it didn't know who was holding the key.

To find the human, I had to switch to AWS CloudTrail. This is the master log of everything happening in your AWS account. I needed to find the exact moment someone "put on the mask" of that Developer Role.

SQL
SELECT eventTime, sourceIPAddress, userIdentity.arn, requestParameters.roleArn
FROM cloudtrail_logs
WHERE eventName = 'AssumeRole'
  AND requestParameters.roleSessionName = 'Session-XYZ'

The Twist: The source IP address didn't come from a hacker in a hoodie halfway across the world. It wasn't one of our VPN addresses either.

It turned out that a developer’s local laptop credentials had been compromised. The attacker wasn't breaking in through a window; they were walking through the front door using a stolen keycard.

Step 4: The Fix (Moving to Modern Security)

In the past, we managed access using a file called aws-auth. It’s messy, hard to read, and easy to break.

To fix this properly, I moved us to EKS Access Entries. Think of this like upgrading from a physical guestbook to a digital badge system. It allows us to grant (and revoke) access directly through the AWS API.

Here is the Terraform code I used to lock it down:

// 1. We create a "Security Boundary" (Access Entry)
resource "aws_eks_access_entry" "security_boundary" {
  cluster_name  = "prod-cluster"
  principal_arn = "arn:aws:iam::123456789012:role/ReadOnly-Developer"
  type          = "STANDARD"
}

// 2. We attach a strictly limited policy (View Only)
resource "aws_eks_access_policy_association" "view_only" {
  cluster_name  = "prod-cluster"
  policy_arn    = "arn:aws:eks::aws:cluster-access-policy/AmazonEKSViewPolicy"
  principal_arn = aws_eks_access_entry.security_boundary.principal_arn
  access_scope {
    type = "cluster"
  }
}

Now, if this role gets compromised again, I can revoke it with a single API call, and that action is instantly logged.

Step 5: The Alarm System

I never want to manually hunt for this again. I set up a "tripwire." If anyone tries to use kubectl exec in production, effectively opening a shell into a container, I get a Slack notification immediately.

We used a CloudWatch Metric Filter for this:

resource "aws_cloudwatch_log_metric_filter" "exec_tripwire" {
  name           = "EKSExecDetection"
  // This pattern looks for the 'connect' verb on the 'exec' subresource
  pattern        = "{ ($.verb = \"connect\") && ($.objectRef.subresource = \"exec\") }"
  log_group_name = "/aws/eks/prod-cluster/cluster"

  metric_transformation {
    name      = "ExecAttempt"
    namespace = "ClusterSecurity"
    value     = "1"
  }
}

The Takeaway
Wearing two caps—DevOps and Forensics is a balancing act.

DevOps is about building fast and keeping the lights on.

Forensics is about proving what happened and ensuring it doesn't happen again.

If you only wear the DevOps cap, you might "fix" the problem but leave the door wide open. If you can’t answer Who did it, Where they came from, and What they changed, you haven't really finished the job.

Next time you see something weird in your cluster, don't just kubectl delete. Stop. Capture. Then fix.

Automation Gone Wrong: Our Cleanup Lambda Deleted Rancher’s EBS Volume (and How Velero Saved Us)

Frank Osasere Idugboe — Fri, 30 Jan 2026 11:00:03 +0000

A real-world incident where an automated cleanup Lambda deleted our Rancher's EBS volume in our development environment. Here's how we recovered using Velero and prevented it from happening again.

You know that Nigerian saying: “The same broom you use to sweep your house can sweep away your blessings”?

Well, our cost-optimization Lambda function just swept away our entire Rancher installation at midnight. 😅

It was 4:40 AM when I got the alert. Rancher UI showing 502 errors. My first thought? “Ah, network wahala again.” But this time, it was different. Our automation had turned against us.

Let me tell you how we went from “Jesus take the wheel” to “we move!” in just 20 minutes.

🔥 The Incident: When Automation Bites Back

The Setup:

Rancher running on AWS EKS in eu-west-1
A Lambda function scheduled to run at midnight to delete unused EBS volumes (saving costs, you know the drill)
Everything working fine... until it wasn’t

The Symptoms:

Rancher UI returning 502 Bad Gateway
Rancher pod stuck in ContainerCreating for 8+ hours
My coffee getting cold while I investigated ☕️

🔍 Investigation: Finding the Culprit

First things first, let’s see what’s happening with our Rancher pod:

kubectl get pods -n cattle-system -o wide

NAME                      READY   STATUS            RESTARTS   AGE
rancher-57774d445-9hqcb   0/1     ContainerCreating   0          8h

Eight hours in ContainerCreating? Something is seriously wrong. Time to dig deeper:

kubectl describe pod rancher-57774d445-9hqcb -n cattle-system | grep -A 20 "Events:"

And there it was, the smoking gun:

Warning  FailedAttachVolume  AttachVolume.Attach failed for volume "pvc-c343abb9-0df7-4c91-b6fa-11da4a13ac00"
rpc error: code = Internal desc = Could not attach volume "vol-0c9a7de28533e72a4" to node
api error InvalidVolume.NotFound: The volume 'vol-0c9a7de28533e72a4' does not exist.

The volume doesn’t exist. 😱

At this point, I remembered our Lambda function. The one that was supposed to save us money by cleaning up unused volumes. The same one that runs at midnight...

Let’s check the PVC:

kubectl get pvc -n cattle-system
NAME          STATUS   VOLUME                                     CAPACITY   ACCESS MODES
rancher-pvc   Bound    pvc-c343abb9-0df7-4c91-b6fa-11da4a13ac00   10Gi       RWO

The PVC thinks it’s bound to a volume that AWS says doesn’t exist. Classic case of “the automation did exactly what we told it to do.”

🕵️ The Root Cause: Too Smart for Our Own Good

Here’s what our Lambda function looked like:
import boto3

def lambda_handler(event, context):
ec2_client = boto3.client('ec2', region_name='eu-west-1')

# Get all available (unused) volumes
response = ec2_client.describe_volumes(
    Filters=[{'Name': 'status', 'Values': ['available']}]
)

# Delete them all! What could go wrong? 🤷‍♂️
for volume in response['Volumes']:
    volume_id = volume['VolumeId']
    print(f"Deleting {volume_id}...")
    ec2_client.delete_volume(VolumeId=volume_id)

The problem? It deleted ALL volumes with status available, including Kubernetes persistent volumes that were temporarily detached during pod restarts or node maintenance.

In Nigerian parlance: We used a sledgehammer to kill a mosquito, and we broke the wall. 😂

🚑 The Recovery: From Panic to Peace in 20 Minutes
Step 1: Check for Backups (Please, Please Have Backups!)

First question in any disaster: Do we have backups?
We were using Velero for cluster backups:

kubectl get backups -n velero
NAME                        AGE
daily-backup-20260130010007 6h47m
daily-backup-20260129040219 27h

Thank God! We have a backup from 01:00 AM. Let’s verify it includes our cattle-system namespace:

kubectl get backup daily-backup-20260130010007 -n velero \
  -o jsonpath='{.spec.includedNamespaces}'

["cattle-system","data-workload","observability"]

Perfect! ✅ Time to bring Rancher back from the dead.

Step 2: Clear the Broken Resources

Before we can restore, we need to clean up the broken PVC and PV.

Scale down Rancher:

kubectl scale deployment rancher -n cattle-system --replicas=0

Now delete the broken resources:

kubectl delete pvc rancher-pvc -n cattle-system
kubectl delete pv pvc-c343abb9-0df7-4c91-b6fa-11da4a13ac00 --force --grace-period=0

Tip: If the PV refuses to delete due to finalizers, remove them:

kubectl patch pv pvc-c343abb9-0df7-4c91-b6fa-11da4a13ac00 -p '{"metadata":{"finalizers":null}}'

Step 3: Velero to the Rescue

Time to restore from our backup. Create a Velero Restore:

kubectl create -f - <<EOF
apiVersion: velero.io/v1
kind: Restore
metadata:
  name: rancher-restore-$(date +%Y%m%d-%H%M%S)
  namespace: velero
spec:
  backupName: daily-backup-20260130010007
  includedNamespaces:
  - cattle-system
  restorePVs: true
  existingResourcePolicy: update
EOF

Check the restore status:

kubectl get restore -n velero

Verify the PVC was recreated:

kubectl get pvc -n cattle-system

NAME          STATUS   VOLUME                                     CAPACITY   ACCESS MODES
rancher-pvc   Bound    pvc-e4849291-fdc3-4a07-a8b9-e14fa93dbbd1   10Gi       RWO

New volume, new life! Now scale Rancher back up:

kubectl scale deployment rancher -n cattle-system --replicas=1

Wait about a minute and check:

kubectl get pods -n cattle-system -l app=rancher

NAME                      READY   STATUS    RESTARTS   AGE
rancher-57774d445-z9wj9   1/1     Running   0          3m7s

🎉 Rancher is back! We move!

🛡️ Prevention: Making Sure This Never Happens Again

Now that we’ve recovered, let’s fix that Lambda function so it doesn’t delete our infrastructure again.

Key insight: Kubernetes (and the EBS CSI driver) tags EBS volumes. We can use those tags to protect K8s-managed volumes.

Here’s the updated Lambda function (with guardrails):

import boto3
import json
from datetime import datetime

def lambda_handler(event, context):
ec2_client = boto3.client('ec2', region_name='eu-west-1')

deleted_volumes = []
skipped_volumes = []
total_size_gb = 0

response = ec2_client.describe_volumes(
    Filters=[{'Name': 'status', 'Values': ['available']}]
)

volumes = response['Volumes']
print(f"Found {len(volumes)} available volumes")

for volume in volumes:
    volume_id = volume['VolumeId']
    volume_size = volume['Size']
    volume_type = volume['VolumeType']

    tags = {tag['Key']: tag['Value'] for tag in volume.get('Tags', [])}
    volume_name = tags.get('Name', 'N/A')

    # 🛡️ PROTECTION RULE 1: Skip Kubernetes volumes
    if any(key.startswith('kubernetes.io/') for key in tags.keys()):
        print(f"⊘ Skipping Kubernetes volume: {volume_id} ({volume_name})")
        skipped_volumes.append({'VolumeId': volume_id, 'Name': volume_name, 'Reason': 'Kubernetes volume'})
        continue

    # 🛡️ PROTECTION RULE 2: Skip volumes tagged as critical
    if tags.get('critical') == 'true':
        print(f"⊘ Skipping critical volume: {volume_id} ({volume_name})")
        skipped_volumes.append({'VolumeId': volume_id, 'Name': volume_name, 'Reason': 'Critical volume'})
        continue

    # 🛡️ PROTECTION RULE 3: Skip production volumes
    if tags.get('environment') == 'production':
        print(f"⊘ Skipping production volume: {volume_id} ({volume_name})")
        skipped_volumes.append({'VolumeId': volume_id, 'Name': volume_name, 'Reason': 'Production environment'})
        continue

    # Safe to delete
    try:
        print(f"Deleting: {volume_id} ({volume_name}) - {volume_size}GB")
        ec2_client.delete_volume(VolumeId=volume_id)

        deleted_volumes.append({'VolumeId': volume_id, 'Name': volume_name, 'Size': volume_size, 'Type': volume_type})
        total_size_gb += volume_size
        print(f"✓ Deleted: {volume_id}")
    except Exception as e:
        print(f"✗ Failed: {volume_id} - {str(e)}")

summary = {
    'Status': 'Success',
    'VolumesDeleted': len(deleted_volumes),
    'VolumesSkipped': len(skipped_volumes),
    'TotalSizeDeleted_GB': total_size_gb,
    'MonthlySavings_USD': round(total_size_gb * 0.11, 2),
    'Timestamp': datetime.utcnow().isoformat()
}

print(f"\n✓ Successfully deleted {len(deleted_volumes)} volumes ({total_size_gb}GB)")
print(f"⊘ Skipped {len(skipped_volumes)} protected volumes")
print(f"💰 Monthly savings: ~${round(total_size_gb * 0.11, 2)}")

return {'statusCode': 200, 'body': json.dumps(summary, default=str)}

Let’s confirm our new Rancher volume has Kubernetes tags:

aws ec2 describe-volumes --volume-ids vol-05c365c66b6c1fed0 \
  --region eu-west-1 --query 'Volumes[0].Tags'

Example tags you’ll typically see:

kubernetes.io/created-for/pvc/namespace: cattle-system
kubernetes.io/created-for/pvc/name: rancher-pvc
kubernetes.io/created-for/pv/name: pvc-e4849291-fdc3-4a07-a8b9-e14fa93dbbd1
ebs.csi.aws.com/cluster: true

Perfect — our updated Lambda will now skip these volumes.

📊 The Timeline: How Fast Can You Recover?

00:00 — Lambda deletes the volume (while we’re sleeping)

01:00 — Velero backup runs (thank God for automation!)

04:40 — Issue discovered (502 errors everywhere)

04:48 — Velero restore initiated

04:55 — Restore completed, new volume created

04:58 — Rancher fully operational (1/1 Ready)

05:04 — Lambda function patched with protection rules

05:06 — Incident documentation completed

Total downtime: ~5 hours (mostly unnoticed)
Active recovery time: ~20 minutes
Lessons learned: priceless

💡 Key Takeaways (The Real Gist)
1) Backups Are Your Best Friend

Without Velero backups, this would have been a “start updating your CV” moment.

Action: Set up automated backups TODAY. Test restores regularly.

2) Automation Without Guardrails Is Dangerous

Our Lambda did exactly what we told it to do. We forgot to tell it what NOT to do.

Action: Add explicit exclusion rules + dry runs + approvals for destructive actions.

3) Tag Everything Like Your Job Depends On It

Use Kubernetes tags, and add your own:

critical=true

environment=production

managed-by=kubernetes

backup=daily

Action: Enforce tagging via AWS Config / SCPs / policy-as-code.

4) Test Your Disaster Recovery Plan

We got lucky. Don’t rely on luck.

Action: Run quarterly DR drills. Restore to a test environment. Time it.

5) Monitor Everything

We could’ve caught this earlier.

Action: Alert on:

PV attach failures

Pods stuck in ContainerCreating > 5 minutes

Lambda deletion logs

Backup failures

6) Document Your Incidents

This post exists because we documented during recovery.

Action: Create incident templates + runbooks.

🎯 Your Action Plan (Start Today!)

Audit your cleanup scripts: what can they delete accidentally?

Install Velero (or any backup tool) and schedule automated backups.

Test restore procedures (don’t just “have backups”, verify them).

Enforce tagging for critical/prod resources.

Add monitoring for K8s storage + automation jobs.

Document runbooks and incident learnings.

b. Apply predefined AWS-managed policies or create custom policies tailored to your organization’s needs.

c. Assign the appropriate permission sets to users and groups.

Implementing Role-Based Access Control (RBAC)

Step 12: Define Roles and Permissions

a. Analyze user requirements and group them by roles (e.g., developer, admin).

b. Use AWS IAM policies to define access scopes based on roles.

c. Attach these policies to the permission sets in AWS SSO.

Step 13: Test Access Control

a. Simulate user logins to verify they have appropriate access.

b. Adjust permissions as needed to align with organizational policies.

Final Steps and Best Practices

Step 14: Monitor and Audit

a. Use AWS CloudTrail to log activity across accounts.

b. Regularly review access logs to ensure compliance with security policies.

Step 15: Enforce Service Control Policies (SCPs)

a. Use SCPs to define what actions can or cannot be performed within the organization.

b. For example, restrict access to certain AWS regions or services for specific accounts.

Step 16: Automate Account Provisioning
Consider using AWS Control Tower for streamlined account creation and governance.

Conclusion

By following these steps, you can set up a multi-account AWS environment with SSO using AWS Organizations.

After reconnaissance, the next phase is scanning, where ethical hackers actively probe the target's systems for vulnerabilities. This involves network scanning, vulnerability scanning, and port scanning. These activities help identify open ports, outdated software, misconfigurations, and other weaknesses that could be exploited by attackers.

Scanning is crucial because it allows ethical hackers to pinpoint specific vulnerabilities that need immediate attention. It sets the stage for the subsequent phases, where these vulnerabilities will be further explored and tested.

3. Gaining Access

The gaining access phase is where ethical hackers attempt to exploit the identified vulnerabilities. This may involve techniques such as password cracking, exploiting software flaws, or leveraging social engineering tactics. The goal here is not to cause harm but to demonstrate the potential damage that could occur in the hands of malicious hackers.

This phase underscores the importance of fixing vulnerabilities promptly. It serves as a wake-up call for organizations, showing them the real-world consequences of lax cybersecurity measures.

4. Maintaining Access

Once access has been gained, ethical hackers work on maintaining it. This phase involves creating backdoors or establishing persistent access points in the target system. By doing so, ethical hackers can demonstrate how attackers might maintain control over a compromised system for an extended period.

Maintaining access highlights the need for continuous monitoring and incident response capabilities. Organizations must be vigilant to detect and respond to unauthorized access promptly.

5. Covering Tracks

The final phase, covering tracks, is crucial for ethical hackers to ensure that their actions do not disrupt the target system or leave traces of their activities. This phase involves erasing logs, deleting files, and obscuring any evidence of the ethical hacking process.

Covering tracks emphasizes the importance of forensic analysis and incident response. By understanding how ethical hackers cover their tracks, organizations can better prepare for real-world cyberattacks and minimize the damage caused.

Conclusion

Ethical hacking is an indispensable practice in today's digital landscape. It empowers organizations to proactively identify and address vulnerabilities before malicious hackers can exploit them. The five phases of ethical hacking – reconnaissance, scanning, gaining access, maintaining access, and covering tracks – provide a structured approach to securing digital assets and ensuring a robust cybersecurity posture.
