Microsoft Warns of Large-Scale Click Fraud Campaign Targeting Gamers

Microsoft Warns of Large-Scale Click Fraud Campaign Targeting Gamers
Sep 19, 2022
Microsoft said it's tracking an ongoing large-scale click fraud campaign targeting gamers by means of stealthily deployed browser extensions on compromised systems. "[The] attackers monetize clicks generated by a browser node-webkit or malicious browser extension secretly installed on devices," Microsoft Security Intelligence said in a sequence of tweets over the weekend. The tech giant's cybersecurity division is tracking the developing threat cluster under the name DEV-0796. Attack chains mounted by the adversary commence with an ISO file that's downloaded onto a victim's machine upon clicking on a malicious ad or comments on YouTube. The ISO file, when opened, is designed to install a browser node-webkit (aka  NW.js ) or rogue browser extension. It's worth noting that the  ISO file  masquerades as hacks and cheats for the Krunker first-person shooter game. Cheats are programs that help gamers gain an added advantage beyond the available capabili

Malvertisers Exploited WebKit 0-Day to Redirect Browser Users to Scam Sites

Malvertisers Exploited WebKit 0-Day to Redirect Browser Users to Scam Sites
Feb 17, 2021
A malvertising group known as "ScamClub" exploited a zero-day vulnerability in WebKit-based browsers to inject malicious payloads that redirected users to fraudulent websites gift card scams. The attacks, first spotted by ad security firm Confiant in late June 2020, leveraged a bug (CVE-2021–1801) that allowed malicious parties to bypass the iframe sandboxing policy in the browser engine that powers Safari and Google Chrome for iOS and run malicious code. Specifically, the technique exploited the manner how WebKit handles JavaScript event listeners , thus making it possible to break out of the sandbox associated with an ad's inline frame element despite the presence of "allow-top-navigation-by-user-activation" attribute that explicitly forbids any redirection unless the click event occurs inside the iframe. To test this hypothesis, the researchers set about creating a simple HTML file containing a cross-origin sandboxed iframe and a button outside it that

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

Microsoft Could Kill Internet Explorer; New Spartan Browser Coming Soon

Microsoft Could Kill Internet Explorer; New Spartan Browser Coming Soon
Dec 30, 2015
Bad News for Internet Explorer fans, if any! Microsoft's almost 20 years old Web browser with a big blue E sign might soon be a thing of the past. With the arrival of Windows 10 , probably by next fall, Microsoft could come up with its brand new browser that's more similar to Mozilla's Firefox and Google's Chrome, but less like Internet Explorer (IE), according to a recent report published by ZDNet. "Ok so Microsoft is about to launch a new browser that's not Internet Explorer and will be the default browser in Windows 10," tweeted Thomas Nigro, a Microsoft Student Partner lead and developer of the modern version of VLC. The browser, codenamed " Spartan ," is a " light-weight " browser with extension support, and multiple sources confirm that this new browser isn't IE12. Instead, Spartan is an entirely new browser that will use Microsoft's Chakra JavaScript engine and Trident rendering engine (as opposed to WebKit
