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
Update Google Chrome Browser to Patch New Critical Security Flaws

Update Google Chrome Browser to Patch New Critical Security Flaws

Sep 19, 2019
Google has released an urgent software update for its Chrome web browser and is urging Windows, Mac, and Linux users to upgrade the application to the latest available version immediately. Started rolling out to users worldwide this Wednesday, the Chrome 77.0.3865.90 version contains security patches for 1 critical and 3 high-risk security vulnerabilities, the most severe of which could allow remote hackers to take control of an affected system. Google has decided to keep details of all four vulnerabilities secret for a few more days in order to prevent hackers from exploiting them and give users enough time to install the Chrome update. For now, Chrome security team has only revealed that all four vulnerabilities are use-after-free issues in different components of the web browser, as mentioned below, the critical of which could lead to remote code execution attacks. The use-after-free vulnerability is a class of memory corruption issue that allows corruption or modificat

Social Media Accounts: The Weak Link in Organizational SaaS Security

Oct 09, 2024SaaS Security / Identity Security
Social media accounts help shape a brand's identity and reputation. These public forums engage directly with customers as they are a hub to connect, share content and answer questions. However, despite the high profile role these accounts have, many organizations overlook social media account security. Many lack the safeguards to prevent unauthorized access — a situation no organization wants as it can quickly spiral to include reputational damage and financial losses.  With the impact this high, the need for deep understanding of social media risks as well as how to protect an organization's social media account are more crucial than ever. This article dives into the details of social media accounts, how social media can be misused and how to protect oneself. Understanding the Layers of Social Media Access Platforms like Facebook, Instagram, and LinkedIn typically have two layers of access.  The Public Facing Page : where brands post content and engage with users.  The Advertis
17-Year-Old Weakness in Firefox Let HTML File Steal Other Files From Device

17-Year-Old Weakness in Firefox Let HTML File Steal Other Files From Device

Jul 03, 2019
Except for phishing and scams, downloading an HTML attachment and opening it locally on your browser was never considered as a severe threat until a security researcher today demonstrated a technique that could allow attackers to steal files stored on a victim's computer. Barak Tawily, an application security researcher, shared his findings with The Hacker News, wherein he successfully developed a new proof-of-concept attack against the latest version of Firefox by leveraging a 17-year-old known issue in the browser. The attack takes advantage of the way Firefox implements Same Origin Policy (SOP) for the "file://" scheme URI (Uniform Resource Identifiers), which allows any file in a folder on a system to get access to files in the same folder and subfolders. Since the Same Origin Policy for the file scheme has not been defined clearly in the RFC by IETF, every browser and software have implemented it differently—some treating all files in a folder as the same

Unpatched Flaw in Xiaomi's Built-in Browser App Lets Hackers Spoof URLs

Unpatched Flaw in Xiaomi's Built-in Browser App Lets Hackers Spoof URLs

Apr 05, 2019
EXCLUSIVE — Beware, if you are using a Xiaomi's Mi or Redmi smartphone, you should immediately update its built-in MI browser or the Mint browser available on Google Play Store for non-Xiaomi Android devices. That's because both web browser apps created by Xiaomi are vulnerable to a critical vulnerability which has not yet been patched even after being privately reported to the company, a researcher told The Hacker News. The vulnerability, identified as CVE-2019-10875 and discovered by security researcher Arif Khan , is a browser address bar spoofing issue that originates because of a logical flaw in the browser's interface, allowing a malicious website to control URLs displayed in the address bar. According to the advisory, affected browsers are not properly handling the "q" query parameter in the URLs, thus fail to display the portion of an https URL before the ?q= substring in the address bar. Since the address bar of a web browser is the most r
New Unpatched macOS Flaw Lets Apps Spy On Your Safari Browsing History

New Unpatched macOS Flaw Lets Apps Spy On Your Safari Browsing History

Feb 12, 2019
A new security vulnerability has been discovered in the latest version of Apple's macOS Mojave that could allow a malicious application to access data stored in restricted folders which are otherwise not accessible to every app. Discovered by application developer Jeff Johnson on February 8, the vulnerability is unpatched at the time of writing and impacts all version of macOS Mojave, including macOS Mojave 10.14.3 Supplemental update released on February 7. Certain folders in macOS Mojave have restricted access that is forbidden by default, like ~/Library/Safari, which can be accessed by only a few applications, such as Finder. However, Johnson discovered a way to bypass these restrictions in Mojave, allowing applications to access ~/Library/Safari without needing any permission from the user or the system, and read users' web browsing history. "My bypass works with the 'hardened runtime' enabled," Johnson said in a blog post published last week.
Beware! Unpatched Safari Browser Hack Lets Attackers Spoof URLs

Beware! Unpatched Safari Browser Hack Lets Attackers Spoof URLs

Sep 12, 2018
A security researcher has discovered a serious vulnerability that could allow attackers to spoof website addresses in the Microsoft Edge web browser for Windows and Apple Safari for iOS. While Microsoft fixed the address bar URL spoofing vulnerability last month as part of its monthly security updates , Safari is still unpatched, potentially leaving Apple users vulnerable to phishing attacks. The phishing attacks today are sophisticated and increasingly more difficult to spot, and this newly discovered vulnerability takes it to another level that can bypass basic indicators like URL and SSL, which are the first things a user checks to determine if a website is fake. Discovered by Pakistan-based security researcher Rafay Baloch, the vulnerability (CVE-2018-8383) is due to a race condition type issue caused by the web browser allowing JavaScript to update the page address in the URL bar while the page is loading. Here's How the URL Spoofing Vulnerability Works Successfu

Chrome Bug Allowed Hackers to Find Out Everything Facebook Knows About You

Aug 16, 2018
With the release of Chrome 68, Google prominently marks all non-HTTPS websites as 'Not Secure' on its browser to make the web a more secure place for Internet users. If you haven't yet, there is another significant reason to immediately switch to the latest version of the Chrome web browser. Ron Masas, a security researcher from Imperva, has discovered a vulnerability in web browsers that could allow attackers to find everything other web platforms, like Facebook and Google, knows about you—and all they need is just trick you into visiting a website. The vulnerability, identified as CVE-2018-6177 , takes advantage of a weakness in audio/video HTML tags and affects all web browsers powered by "Blink Engine," including Google Chrome. To illustrate the attack scenario, the researcher took an example of Facebook, a popular social media platform that collects in-depth profiling information on its users, including their age, gender, where you have been (loca
