In December 2024, Volkswagen Group experienced a massive data breach, exposing sensitive information of approximately 800,000 electric vehicle (EV) owners across its brands, including Volkswagen, Audi, Seat, and Skoda.
The breach, initially reported by Spiegel, was caused by a misconfigured Amazon cloud storage system managed by Volkswagen’s software subsidiary, Cariad. This misconfiguration left personal and location data publicly accessible online for several months.
Key Statistics & Losses
- 800,000+ individuals affected
- Data exposed: Vehicle locations, timestamps of EV activations, email addresses, phone numbers, and home addresses
- Notable victims: Two German politicians, Hamburg police, and citizens across Germany, Norway, Sweden, UK, Netherlands, France, Belgium, and Denmark
- Reported by: Chaos Computer Club (CCC), an ethical hacking organization
- Immediate Action: Cariad closed the access on the same day after CCC’s notification
This breach raises serious concerns about cloud security and highlights the risks of AWS misconfigurations in large-scale enterprises like Volkswagen.
What Caused the Breach? The AWS Misconfiguration
Despite AWS offering a secure infrastructure, misconfigurations by end users can expose sensitive data. In Volkswagen’s case, the following issues led to the breach:
- Publicly Accessible Amazon S3 Storage: Sensitive data was stored in an S3 bucket with overly permissive access settings, making it accessible online.
- Lack of Proper IAM Controls: Inadequate Identity and Access Management (IAM) settings may have allowed unauthorized users to access the data.
- No Continuous Security Monitoring: The misconfiguration remained undetected for months, highlighting the absence of automated security posture monitoring.
Why AWS Alone is Not Enough
While AWS provides secure infrastructure, it is not responsible for securing user configurations. This is known as the Shared Responsibility Model—AWS secures the cloud, but customers must secure their workloads. Without a Cloud Native Application Protection Platform (CNAPP) like AccuKnox, detecting and remediating such misconfigurations becomes incredibly difficult, especially for global enterprises managing vast cloud infrastructures.
The Challenge of Visibility in Large-Scale Cloud Environments
Volkswagen, like many global enterprises, operates a highly distributed cloud environment with workloads spread across multiple regions, accounts, and services.
Pain Points in Cloud Security Management
| Challenges | Why It is a Problem | How AccuKnox Helps |
|---|---|---|
| Lack of Cloud Asset Visibility | Managing distributed assets is difficult, leading to blind spots. | Automates asset discovery across all cloud environments. |
| Too Many Findings, No Prioritization | Security teams get overwhelmed by alerts. | Uses risk-based prioritization to focus on high-impact vulnerabilities first. |
| Triaging Misconfigurations | It is hard to differentiate between critical and low-risk issues. | Triangulates misconfigurations and automatically recommends fixes. |
| Manual Compliance Management | Keeping up security frameworks is resource-intensive. | Automates compliance enforcement for AWS and industry standards. |

With AccuKnox’s Compliance Dashboard, Volkswagen could have detected the AWS misconfiguration before it led to a breach.
How AccuKnox Could Have Prevented This Breach
If Volkswagen had implemented AccuKnox’s CNAPP SaaS, it could have proactively detected and remediated the misconfigured public S3 bucket before it led to a data breach. AccuKnox provides real-time monitoring of cloud assets, ensuring organizations have full visibility into their cloud environments and can quickly identify security gaps. With automated risk-based prioritization, AccuKnox helps teams focus on critical misconfigurations first, preventing sensitive data from being exposed due to overlooked security flaws. Additionally, AccuKnox enforces Zero Trust Security by locking down over-permissive IAM roles, reducing the risk of unauthorized access. Its automated compliance management ensures organizations stay aligned with security standards like AWS CIS, NIST, and PCI DSS, minimizing vulnerabilities. With seamless cloud-native integration across AWS, Kubernetes, and hybrid environments, AccuKnox enables companies like Volkswagen to maintain a secure, compliant, and resilient cloud infrastructure—avoiding breaches before they happen.
By leveraging AccuKnox, Volkswagen could have avoided the breach, protected 800,000+ customers, and maintained regulatory compliance effortlessly.
AWS Security Scenarios with AccuKnox
If you have AWS Cloud Accounts that you wish to secure via AccuKnox SaaS, check out the Onboarding AWS Cloud Account Documentation.
AccuKnox finds critical issues from your codebase and highlights threat priority along with proposing a solution. Exposed S3 secret keys in EC2 and S3 buckets with disabled ACLS on AWS and other cloud platforms.
1. S3 Public Exposure
Identification
To identify publicly exposed S3 buckets:
- Navigate to Issues > Findings.
- Apply the Cloud Findings filter.
- Search for the keyword public.
- Group by Findings to see all public exposure cases.
Impact
- Attackers can enumerate publicly exposed buckets to identify accessible data.
- Once an exposed bucket is identified, attackers can perform fuzzing against the bucket URL to extract sensitive information.
Remediation
AccuKnox provides solution reference links to assist in remediation.
To remediate the findings:
- Navigate to Issues > Findings.
- Select the finding and create a ticket for remediation.
2. Open SSH Exposure
Identification
To identify publicly exposed SSH ports:
- Navigate to Issues > Findings.
- Apply the Cloud Findings filter.
- Search for the keyword public.
- Group by Findings to see all open SSH exposure cases.
Impact
If an EC2 instance is misconfigured, an attacker can gain control over resources. Exposure, combined with poor authentication, allows attackers to perform brute force attacks using tools such as:
Nmap:
nmap -p 22 --script ssh-brute --script-args userdb=users.lst,passdb=pass.lst
--script-args ssh-brute.timeout=4s <target>Metasploit:
msf > use auxiliary/scanner/ssh/ssh_login
msf auxiliary(ssh_login) > set RHOSTS <target>
msf auxiliary(ssh_login) > set USERPASS_FILE
/usr/share/metasploit-framework/data/wordlists/root_userpass.txt
msf auxiliary(ssh_login) > set PASSWORD
/usr/share/metasploit-framework/data/wordlists/rockyou.txt Run
Hydra:
hydra -L /usr/share/wordlists.rockyou.txt -P /usr/share/wordlists/rockyRemediation
AccuKnox provides solution reference links to assist in remediation.
To remediate the findings:
