Google Chrome users still vulnerable to multiple zero-day attacks


As business users and consumers have moved most of their workloads to the cloud, more and more of their work is being done in web browsers such as Google Chrome as opposed to in applications installed locally on their systems.

This means that the web browser is now an essential yet vulnerable entry point that if compromised, could give cybercriminals access to a user’s entire digital life including their email, online banking, social networks and more. However, despite this risk, users are failing to update to the latest version of Google Chrome according to new research from Menlo Security.

Tianfu Cup Hackers Exploit Microsoft Windows, Google Chrome, and iOS in Minutes

How easy is it hack some of the world’s most popular software, such as Microsoft’s Windows 10 and Google’s Chrome? Well, quite easy it seems, at least for some of the world’s best hackers. That’s what happened at this year’s Tianfu Cup in China, where brand new exploits were used against leading services.

If you are unfamiliar with the Tianfu Cup, it is one of the biggest hacking competitions in the world and the largest in China. Held in central China city Chengdu each year, the competition has become a proving ground for security researchers.

It is also a place where the best tech software can test their mettle against zero-day exploits. Over the two-day event, security researchers test how popular software can handle zero-day vulnerability threats.

Hackers at the Tianfu Cup are looking to exploit apps and programs with never-seen-before attacks. If they succeed a point is earned, and the researchers with the most points win prizes. Last year, Microsoft Edge was successfully breached, and it seems Windows 10 was this year.

While that’s not good news for Microsoft, the company is certainly not alone. In fact, many leading platforms and services were compromised during the event. It is worth noting companies welcome these hackathons for exposing issues in software that can be fixed before an in-the-wild exploit is made.

“Many mature and hard targets have been pwned on this year’s contest,” organizers said today. The following services were successfully breached:

  • iOS 14 running on an iPhone 11 Pro
  • Samsung Galaxy S20
  • Windows 10 v2004 (April 2020 edition)
  • Ubuntu
  • Chrome
  • Safari
  • Firefox
  • Adobe PDF Reader
  • Docker (Community Edition)
  • VMWare EXSi (hypervisor)
  • QEMU (emulator & virtualizer)
  • TP-Link and ASUS router firmware

Fifteen Chinese hacking groups took part in the Tianfu Cup this year. Each hacker gets three five-minute windows to attempt to…

Google squashes two more Chrome bugs under active attacks


The updates come on the heels of news of attacks exploiting another zero-day in Chrome in tandem with a previously-unknown Windows flaw

Two weeks after patching an actively-exploited vulnerability affecting Chrome for desktop, Google is squashing another zero-day bug in the browser’s version for Windows, macOS, and Linux, as well as pushing out an update for Chrome for Android that plugs yet another security loophole that is being exploited in the wild.

“Google is aware of reports that an exploit for CVE-2020-16009 exists in the wild,” said the tech giant about the newly-disclosed flaw that stems from an inappropriate implementation in the V8 JavaScript engine and impacts the browser’s desktop versions.

The bug, classified as high-severity, was discovered by researchers from Google’s Threat Analysis Group and Project Zero. Details about the vulnerability are very sparse due to Google’s policy that clearly states that “access to bug details and links may be kept restricted until a majority of users are updated with a fix.”

Per the National Vulnerability Database, the flaw “could allow an attacker to potentially exploit heap corruption via a crafted HTML page.”

Users would do well to update their browsers to the latest version (86.0.4240.183) as soon as possible. If you have automatic updates enabled, your browser should update by itself. Otherwise you’ll have to do it manually by navigating to the About Google Chrome section, which can be found under Help in the side menu.

The update also brings fixes for a total of 10 vulnerabilities, with Google specifically listing seven high-risk flaws where the fixes were contributed by external…
