Malvertising group dubbed eGobbler hijacked 1.16 billion ad impressions between August 1 and September 23. Group was previously observed by Confiant researchers in April using a Chrome for iOS exploit to circumvent the browser’s built-in pop-up blocker to deliver fake ads to 500 million sessions of users from the U.S. and multiple European Union countries in under a week. This time around, they targeted Windows, Linux, and macOS desktop devices in another extensive series of malvertising attacks.
