In September 2000, security watchdog website Securitywatch.com notified Digital Convergence of a security vulnerability on the Digital Convergence website that exposed private information about CueCat users. Digital Convergence immediately shut down that part of their website, and their investigation concluded that approximately 140,000 CueCat users who had registered their CueCat were exposed to a breach that revealed their name, email address, age range, gender and zip code. This was not a breach of the main user database itself, but a flat text file used only for reporting purposes that was generated by ColdFusion code that was saved on a publicly available portion of the Digital Convergence web server.
