About This Breach
The incident compromised backend order databases operated via autopartsemail.biz, with records subsequently shared across breach monitoring sources.
What information was affected in the Quality Used Transmissions incident?
The leaked dataset encompasses comprehensive customer inquiries, vehicle transmission quote requests, and order dispatch records, exposing 2,885,501 unique customer accounts. The exposed data classes include:
- Customer Contact Details: Email addresses, telephone numbers, and full customer names.
- Vehicle & Order Data: Vehicle make, model, year, transmission specifications, and quote transaction IDs.
- Shipping & Transaction Metadata: Shipping addresses, billing logs, and automated customer dispatch logs.
How many users were affected?
The validated and deduplicated email catalog contains 2,885,501 unique canonical email addresses out of over 6.01 million total customer records.
Technical analysis and security implications
The incident reflects an unauthorized export of backend MySQL tables supporting the company's auto-response and quote fulfillment operations. Because victims had specifically requested expensive replacement automotive powertrains, threat actors can weaponize the detailed vehicle and contact data for targeted fraud, including counterfeit warranty renewal calls, fake shipping invoice phishing, and advance-fee parts scams.
What actions should affected users take?
Customers who requested quotes or purchased parts from Quality Used Transmissions should:
- Exercise extreme caution regarding unsolicited calls or emails purporting to represent auto part sellers, shipping companies, or extended warranty providers.
- Verify any unexpected shipping or warranty notifications directly through verified merchant support lines.
- Ensure multi-factor authentication (MFA) is active on personal email accounts.
