A privilege escalation bug has been discovered in Windows' task scheduler and revealed on Twitter. A proof-of-concept has been published, and the vulnerability has been confirmed to be present in a "fully-patched 64-bit Windows 10 system".

The security flaw was exposed on Twitter by user SandboxEscaper -- who has since deleted his or her account. An advisory about the vulnerability has been posted on CERT/CC, and Microsoft says that it is working to fix the problem.

The CEO of Epic Games has slammed Google's "irresponsible" disclosure of a security bug in its hit game Fortnite. Tim Sweeney accused Google of trying to "score cheap PR points" by revealing a vulnerability in the game's installer.

Epic chose to bypass Google Play when it released Fortnite for Android leading to concerns about security. On Friday, Google revealed details of a security flaw that could be exploited to secretly install malware onto people's phones.

Following the success of the iPhone X, the tech world is waiting to see what Apple has up its sleeve next -- and with new devices expected to be announced mid-September, we shouldn't have to wait too long to find out. Now a new report suggests that next month we'll see not just one or two new iPhones... but three.

Citing "people familiar with the matter", Bloomberg says that Apple is set to launch no fewer than three handsets with the full-screen look of the current iPhone X. The trio of phones has been designed to have broader appeal with a wider range of pricing, sources say.

Three people have been killed and several injured in a shooting at a video game tournament in Jacksonville, Florida. A gunman shot two participants dead before killing himself at the event which was livestreamed on Twitch.

Police say that in addition to the three fatalities, eleven people were injured in the shooting. The shooter has been named as David Katz from Baltimore; he is said to have become angry after losing the tournament and pulled out a handgun.

It seems that the concerns about Fortnite's security were well-founded -- although not necessarily for the reasons some people might have expected. Epic Games has been criticized for its decision not to make Fortnite available through Google Play, leading Google to show warnings to anyone conducting searches for the game.

Now a Google engineer just revealed that the first version of Epic's installer had a serious security vulnerability, placing Android users at risk. A post on Google's Issue Tracker shows that the installer could be abused to secretly download and install any app with any level of permissions -- a Man-in-the-Disk exploit.

T-Mobile has revealed that it fell victim to a security incident earlier in the week, and details of around 2.3 million accounts were accessed.

The hack attack took place on Monday, August 20, and while T-Mobile stresses that no financial data was taken, it concedes that it detected "unauthorized capture of some information". The exposed data includes names, billing zip code, phone number, email address, account number and account type, which would be enough for hackers to launch successful phishing attacks.

Security is a serious business (including for Fortnite-maker Epic Games), but it's not something most people take seriously enough -- as the number of weak and reused passwords out there shows. Epic, however, has just given players of its hit game an incentive to enable two-factor authentication on their account.

By enabling 2FA in Fortnite, players can unlock a hidden extra -- the Boogiedown emote. While this is undoubtedly a form of bribery, it is no bad thing. There are just a few simple steps you need to follow to access the new emote.

The prospect of running Linux apps on a Chromebook is something that has many people excited since Google first announced the plans.

For those who like to live on the edge with the Canary and Dev builds of Chrome OS, Linux apps are already a reality -- but what about everyone else? While we know that Linux app support is coming to a range of Chromebooks from Lenovo, Acer, Dell and others, a post on the Chromium Gerrit reveals that devices running Linux 3.14 or older will miss out.

Facebook bought Onavo and its VPN tool back in 2013, and ever since there have been concerns about how the social network uses the tool to gather data -- even when it is disabled.

Now Apple -- itself not a stranger to allegations of privacy violations --  has taken objections to the way Facebook sucks up data from its users through the Ovano Protect VPN app. The iPhone-maker warned Facebook that it was violating its rules on data collection and suggested that the company might want to voluntarily pull the app before it was forcibly removed from the App Store.

In the world of non-console gaming, the Windows platform reigns supreme. That's not to say that Mac and Linux users aren't gamers, but their computer-based gaming choices are rather more limited thanks to developers' tendency to offer Windows support over anything else.

Now Valve is looking to change things with its Steam platform. The latest version of Steam Play makes it possible to play some Windows games on Linux, greatly increasing the size of the gaming catalog available to Linux-based gamers.

If you're in the UK, you'll know that this weekend is the August Bank Holiday. This not only means a day off work -- for most people, at least -- but also big Black Friday-type sales from major retailers.

Amazon is one of those offering big discounts, and you don't have to wait until the weekend to make a saving. For the next week, from today until next Wednesday, the online retailer has some incredible deals on Surface tablets and laptops meaning that there's never been a better time to buy one.

One of the incentives to pay for a service -- from Spotify through Duolingo to YouTube Premium -- is the pleasure of an ad-free experience. Advertising exists in the free versions to help pay for the services, so it only seems fair that those who decide to pay a monthly fee aren't pestered by ads.

Twitch doesn't agree. Starting next month, even if you pay for a Twitch Prime subscription you will still be subjected to ads. The reason? Money, of course.

The ability to "unsend" emails has arrived in Gmail for Android -- for some people at least. The feature is already available on iOS and on the web version of Gmail, but now some Android users are finding that they have the option available on their phones too.

Google has not made any sort of announcement about the rollout of the feature, and it seems as though it could be a server-side update rather than a new version of the app. But if you're one of the lucky ones, here's how to make use of this handy option.

Speed, accuracy and weight are all important factors when it comes to gaming mice, and this is something Logitech has taken into account over the two years it spent designing and building the Logitech G PRO Wireless Gaming Mouse.

Using LIGHTSPEED wireless technology, Logitech says that it is able to offer a lag-free gaming experience -- something which is generally not possible with a wireless mouse. Logitech is keen to point out that more than 50 professional gamers were involved in the design of this ambidextrous mouse and claims it is "the only wireless solution that provides pro grade performance and is actively used in tournament play by top professionals".

Logitech has announced its first ever vertical mouse. Appropriately named the MX Vertical, the device is described as the company's "most advanced ergonomic mouse".

Available in any color you want, so long as that color is black, the MX Vertical has been designed to eliminate wrist pain by enabling you to use it with what Logitech says is "a natural handshake position". Oh... and it looks a bit weird.
