Over A Billion Malicious Ad Impressions Exploit WebKit Flaw to Target Apple Users

Over A Billion Malicious Ad Impressions Exploit WebKit Flaw to Target Apple Users

Oct 01, 2019
The infamous eGobbler hacking group that surfaced online earlier this year with massive malvertising campaigns has now been caught running a new campaign exploiting two browser vulnerabilities to show intrusive pop-up ads and forcefully redirect users to malicious websites. To be noted, hackers haven't found any way to run ads for free; instead, the modus operandi of eGobbler attackers involves high budgets to display billions of ad impressions on high profile websites through legit ad networks. But rather than relying on visitors' willful interaction with advertisements online, eGobbler uses browser (Chrome and Safari) exploits to achieve maximum click rate and successfully hijack as many users' sessions as possible. In its previous malvertising campaign, eGobbler group was exploiting a then-zero-day vulnerability (CVE-2019-5840) in Chrome for iOS back in April , which allowed them to successfully bypass browser's built-in pop-up blocker on iOS devices and hij...
