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

October 01, 2019Mohit Kumar
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
Chinese Hacker Publishes PoC for Remote iOS 12 Jailbreak On iPhone X

Chinese Hacker Publishes PoC for Remote iOS 12 Jailbreak On iPhone X

Here we have great news for all iPhone Jailbreak lovers and concerning one for the rest of iPhone users. A Chinese cybersecurity researcher has today revealed technical details of critical vulnerabilities in Apple Safari web browser and iOS that could allow a remote attacker to jailbreak and compromise victims' iPhoneX running iOS 12.1.2 and before versions. To do so, all an attacker needs to do is trick iPhoneX users into opening a specially crafted web page using Safari browser, that's it. However, finding flaws and creating a working exploit to carry out such attacks is not as easy as it may sound for every iOS hacker. Discovered by security researcher Qixun Zhao of Qihoo 360's Vulcan Team, the exploit takes advantage of two security vulnerabilities that were first demonstrated at TianfuCup hacking contest held in November last year and then was later responsibly reported to the Apple security team. Zhao today released some details of and a proof-of-concep

Earlier this week Dropbox team unveiled details of three critical vulnerabilities in Apple macOS operating system, which altogether could allow a remote attacker to execute malicious code on a targeted Mac computer just by convincing a victim into visiting a malicious web page. The reported vulnerabilities were originally discovered by Syndis , a cybersecurity firm hired by Dropbox to conduct simulated penetration testing attacks as Red Team on the company's IT infrastructure, including Apple software used by Dropbox . The vulnerabilities were discovered and disclosed to Apple security team in February this year, which were then patched by Apple just over one month later with the release of its  March security updates . DropBox applauded Apple for its quick response to its bug report. According to DropBox, the vulnerabilities discovered by Syndis didn't just affect its macOS fleet, but also affected all Safari users running the latest version of the web browser and op
Chrome, Firefox, Edge and Safari Plans to Disable TLS 1.0 and 1.1 in 2020

Chrome, Firefox, Edge and Safari Plans to Disable TLS 1.0 and 1.1 in 2020

October 15, 2018Swati Khandelwal
All major web browsers, including Google Chrome, Apple Safari, Microsoft Edge, Internet Explorer, and Mozilla Firefox, altogether today announced to soon remove support for TLS 1.0 (20-year-old) and TLS 1.1 (12-year-old) communication encryption protocols. Developed initially as Secure Sockets Layer (SSL) protocol, Transport Layer Security (TLS) is an updated cryptographic protocol used to establish a secure and encrypted communications channel between clients and servers. There are currently four versions of the TLS protocol—TLS 1.0, 1.1, 1.2 and 1.3 ( latest )—but older versions, TLS 1.0 and 1.1, are known to be vulnerable to a number of critical attacks, such as  POODLE  and  BEAST . Since TLS implementation in all major web browsers and applications supports downgrade negotiation process, it leaves an opportunity for attackers to exploit weaker protocols even if a server supports the latest version. All Major Web Browsers Will Remove TLS 1.0 and TLS 1.1 Support in 2020
