Valve's popular PC gaming platform Steam is vulnerable to a hugely damaging zero-day security vulnerability, experts have warned.

According to new findings, around 72 million Windows users are at risk of having their systems taken over by an attacker who could then install malware, steal data, compromise passwords and more.

The vulnerability was disclosed by security researcher Vasily Kravets, who discovered a privilege escalation vulnerability which could allow an attacker with minimal user permissions to gain the same levels of access as the system admin.

Zero-day defenses are a good reason why you need the latest version of Windows 10

A threat actor could take advantage of this by launching malware using those raised privileges, Kravets explained, saying:

"Some of the threats will remain even being run without administrator rights.

Samsung recently added two new smartphones to its Galaxy Note lineup at its successful ‘Unpacked’ launch event.

Along with Galaxy Note 10 and Note 10+, the South Korean-based smartphone announced a plethora of devices which includes Galaxy Watch Active 2 and Galaxy Book S. The all-new Galaxy Book S make use of the Snapdragon 8CX chipset offering LTE connectivity on Windows 10.

Here is everything you need to know about the newly launched Samsung Galaxy Book S.

Samsung Galaxy Book S: Specifications, Features

Valve's popular PC gaming platform Steam is vulnerable to a zero-day security vulnerability which could leave 72m Windows users at risk of having their systems taken over by an attacker who could then install malware, steal data, compromise passwords and more.

The vulnerability was disclosed by a security researcher named Vasily Kravets just 45 days after submitting his report on the matter to Valve.

Typically researchers wait 90 days before publicly disclosing a vulnerability as it gives the affected businesses time to fix the vulnerabilities in their software.

Kravets discovered a privilege escalation vulnerability which could allow an attacker with minimal user permissions to gain the same levels of access as the system admin.

A threat actor could take advantage of this by launching malware using those raised privileges.

Kravets explained just how serious the vulnerability is, saying:

Microsoft emitted two fresh builds for October's Windows 10 last night, although which one you'll get depends on your current build or, for new Insiders, a "virtual coin toss".

The company had previously warned that it would be shipping the updates that will become the 19H2 release with features turned off by default.

It could then test turning them on in a controlled manner.

Thus those cautious souls on the Slow Ring, currently prodding 19H2, will receive 18362.10012 with the new toys turned off if they are coming from 18362.10005.

Those on 18362.10006 will get 18362.10013, which has the features on.

Oh, and those in the 18362.10012 group will also have features from the previous release, such as they were, turned off as well.

This is an excerpt from a story delivered exclusively to Business Insider Intelligence Connectivity & Tech subscribers.

Samsung unveiled an array of new products at its Unpacked event in New York earlier this week, including a pair of new phones in its Galaxy Note series, a laptop, a new version of its smart pen, and special smartwatch variants (that build on a watch announced earlier this week).

Here are a few of the more interesting developments from that event.

Samsung partnered with Microsoft to bridge the gap between Windows and Android.

Microsoft will bundle its Your Phone app on the forthcoming Galaxy Note 10.

The photo gallery app on the Galaxy Note 10 will also sync to Microsoft's OneDrive cloud storage service, in a similar functionality to that which Google provides via its Photos app for its Pixel phones.

Windows 10 has introduced support for DTS:X and more immersive audio for movies and games, while bringing quality surround sound to stereo headphones – although this is all still in testing.

This functionality is delivered by the DTS Sound Unbound app which brings support for DTS:X and DTS Headphone:X to your PC (and eventually Xbox, too).

These new DTS:X technologies work together with Microsoft’s Spatial Sound framework in Windows 10.

There are a few things to note here: the free offering only allows a simple trial, and the app is still a work in progress anyway, plus you’ll need to be a Windows 10 tester.

Specifically you’ll need to be running at least build 18898 (released back in May) or better, which is the preview for the major Windows 10 update destined to land in the first half of 2020.
