Abstract

A threat detection system receives links from emails opened in web browsers. The received links are compared with a whitelist of trusted links and blacklisted links associated with security threats. The threat detection system sends trusted identifiers when the received links are identified in the whitelist and sends block identifiers back to the web browsers when the received links are identified in the blacklist. The trusted identifiers cause the web browsers to display a trusted message and the block identifiers cause the web browsers to remove the received link and display a warning message. The threat detection system may receive threat reports for suspected links from employees of a same enterprise and allow an enterprise security administrator to asynchronously update the blacklists and whitelists based on the threat reports received from the enterprise users.
