Summary

Flock, an automatic license plate reader (ALPR) company, inadvertently exposed sensitive police search data, including specific license plates and the reasons for their searches, through common search engines such as DuckDuckGo and Bing. This discovery, made by privacy advocates and 404 Media and confirmed by Flock, represents an unusual data breach demonstrating how surveillance technology can leak information unexpectedly. The NoCo Privacy Coalition, an activist group, first shared evidence of these search engine results with 404 Media in May. This incident follows a previous report by 404 Media detailing Flock's exposure of live camera feeds to the internet. The article, published on Jun 11, 2026, highlights ongoing concerns regarding data security within ALPR systems.

Key takeaway

For AI Security Engineers managing surveillance systems, this incident underscores the critical need to audit third-party vendor data handling. You should proactively assess how your ALPR data, including search queries and reasons, might be indexed by public search engines like DuckDuckGo or Bing. Implement stringent data egress controls and regularly verify that sensitive operational details are not inadvertently exposed, mitigating unexpected data breach vectors.
