Zoom Stealer browser extensions harvest corporate meeting intelligence

A newly discovered campaign called Zoom Stealer is targeting 2.2 million users across Chrome, Firefox, and Microsoft Edge browsers through 18 malicious extensions. These extensions are designed to harvest corporate meeting intelligence by collecting sensitive data from online meetings including URLs, meeting IDs, topics, descriptions, and embedded passwords. The campaign represents a significant threat to corporate security as it specifically targets business communications and meeting data. The malicious extensions operate across multiple major browsers, indicating a broad and coordinated attack strategy. This type of data harvesting could lead to corporate espionage, unauthorized access to sensitive business discussions, and compromise of meeting security credentials.
