A threat actor leaked Toyota’s customer data on a dark web forum. The file shared by the hacker contained 240GB of data, including contact and financial information, emails, and more. The Japanese automaker acknowledged the leak but later backtracked, claiming it wasn’t a breach and that the data was stolen from a third-party entity misrepresented as Toyota. Below, I discuss the security incident in detail, along with tips on how to protect yourself from being targeted by hackers.

What you need to know about the breach
A hacker group called ZeroSevenGroup claimed on a dark web forum that they stole 240GB of data from Toyota, including info on employees, customers, contracts, and financial details, according to Bleeping Computer. They also said they gathered network infrastructure info and credentials using ADRecon, an open-source tool that pulls loads of data from Active Directory systems.
“We have hacked a branch in United States to one of the biggest automotive manufacturer in the world (TOYOTA). We are really glad to share the files with you here for free. The data size: 240 GB,” the threat actor claimed.
The hacker specifically claimed they have access to everything: contacts, financial data, customer info, schemes, employee details, photos, databases, network infrastructure, emails, and “a lot of perfect data.”
It’s not clear exactly when the breach happened, but Bleeping Computer found that the files were stolen—or at least created—on December 25, 2022. This lines up with a data breach around the same time that hit Toyota’s subsidiary, Toyota Financial Services (TFS). Back then, the company warned customers that their data had been compromised. But there’s no confirmation if the two incidents are related.

Toyota’s response
“We are aware of the situation. The issue is limited in scope and is not a system-wide issue,” Toyota told Bleeping Computer when asked to verify the hacker’s claims. The company also mentioned that it’s “engaged with those who are impacted and will provide assistance if needed.”
However, the next day, a spokesperson informed the site that Toyota Motor North America’s systems were “not breached or compromised” and that the data was stolen from what appears to be “a third-party entity that is misrepresented as Toyota.”
The spokesperson declined to reveal the name of the breached third party, stating that Toyota Motor North America was “not at liberty to disclose” that information.
This reversal raises questions about Toyota’s transparency and incident response protocols. The company’s reluctance to provide details about the alleged third-party entity involved further complicates the situation.

Scope and impact
The leaked data reportedly includes:
- Customer and employee personal information
- Financial records and contracts
- Network infrastructure details
- Emails and internal communications
With 240GB of data exposed, the potential impact on individuals and the company could be substantial.
Timing and detection
The files appear to have been created or stolen on December 25, 2022, suggesting a significant delay in detection or disclosure. This lag time is concerning, as it potentially gave attackers ample opportunity to exploit the stolen information.
A pattern of security incidents
This breach is not an isolated incident for Toyota. The company has faced multiple security challenges in recent years:
- A ransomware attack on Toyota Financial Services in 2023
- Exposure of customer car-location data for 2.15 million users over a decade due to cloud misconfigurations
- Additional cloud service misconfigurations leaking customer data for over seven years
These recurring issues point to potential systemic weaknesses in Toyota’s cybersecurity infrastructure and practices.
Industry implications
The automotive industry has become an increasingly attractive target for cybercriminals. This incident highlights the need for robust security measures, especially as vehicles become more connected and data-driven.
4 ways to protect yourself in light of the Toyota security incident
Below are a few ways to protect yourself following the Toyota breach.
1) Enable two-factor authentication: Activate two-factor authentication (2FA) on any accounts tied to Toyota services, including email, financial accounts, and customer portals. 2FA adds an extra layer of security by requiring a second piece of information, like a code sent to your phone, along with your password when logging in. This makes it much more difficult for hackers to access your accounts, even if your password has been compromised. By enabling 2FA, you can significantly reduce the risk of unauthorized access and better protect your sensitive data in light of the Toyota breach.
2) Use personal data removal services: Consider investing in personal data removal services that specialize in continuously monitoring and removing your personal information from various online databases and websites. I mentioned above that hackers are also stealing your IDs to validate the data. These IDs can be misused in more ways than you can imagine, including impersonation.
A service like Incogni can help you remove all this personal information from the internet. It has a very clean interface and will scan websites for your information and remove it and keep it removed.

3) Monitor financial accounts: Regularly check your bank statements, credit card activity, and any Toyota Financial Services accounts for suspicious transactions. If you notice anything unusual, report it to your bank or financial institution immediately.
4) Watch out for phishing scams: In the aftermath of breaches like this, phishing attempts may increase. Be cautious of emails or messages that ask for personal information or direct you to click suspicious links. Verify the sender’s identity before engaging with such communications.
The best way to protect yourself from clicking malicious links is to have antivirus protection installed on all your devices. This can also alert you of any phishing emails or ransomware scams.
My top pick is TotalAV, and you can get a limited-time deal for CyberGuy readers: $19 your first year (80% off) for the TotalAV Antivirus Pro package.

Kurt’s key takeaway
In light of this breach, it’s clear that data security is a critical concern for both companies and their customers. Whether the breach occurred directly at Toyota or through a third-party entity, the fact remains that sensitive information has been exposed, putting individuals at risk. It’s a reminder of the importance of staying vigilant, protecting your accounts with tools like two-factor authentication, and regularly monitoring your financial activity for any signs of suspicious behavior.
