On February 27, 2025, KNFILTERS.COM appeared on the public leak site operated by the Clop ransomware group. The company, formally known as K&N Engineering, Inc., confirmed that internal files had been exfiltrated during a ransomware incident. While the exact number of people whose information was taken remains unknown, anyone who has purchased from the California-based performance filter maker, interacted with its customer service, or had their details stored in the company’s systems may be affected.

What Public Reporting Shows
Public reporting indicates that Clop added KNFILTERS.COM to its leak portal on February 27, 2025. The data consists of internal files exfiltrated after a ransomware deployment. No precise victim count has been published, and the precise contents of the stolen files have not been independently verified by third parties. Available reporting describes the incident as a classic ransomware extortion case in which the attackers threaten to publish the stolen data unless their demands are met.
Why This Matters for You and Your Family
When a retailer like K&N suffers a breach, the information exposed often includes names, addresses, phone numbers, email addresses, and payment details tied to customer orders. If you or anyone in your household has ever bought air filters, intake kits, or related automotive parts from knfilters.com, your contact and transaction records could now sit in a criminal archive. That information does not expire. It can be sold, traded, or used months or years later to impersonate you, file fraudulent tax returns, or open accounts in your name. Children’s information is sometimes swept up in these incidents through family orders or shared email addresses, turning a single breach into a household problem.
The Doxxing and Identity-Chain Implications
Stolen customer files rarely stay isolated. Attackers and data brokers routinely combine them with other leaks to build detailed profiles. An email address from this claimed breach can be linked to your social-media handles, gaming usernames, or school records for your children. Once those connections are made, targeted doxxing becomes straightforward. Credential leaks like this one frequently cascade into account takeovers on gaming platforms, where kids’ usernames and passwords are reused. A compromised Roblox or Fortnite account can expose chat logs, linked phone numbers, and home addresses, feeding the next round of harassment or identity theft.
