It's around three weeks since Microsoft first urged Windows users to patch their systems against the BlueKeep (CVE-2019-0708) vulnerability. Concerned that not enough people were taking notice, the company then issued a further warning stressing the importance of installing a patch.

Now the NSA has got involved, joining Microsoft in begging users to secure their Windows XP and Windows 7 computers. The agency says that is "concerned that malicious cyber actors will use the vulnerability in ransomware and exploit kits containing other known exploits, increasing capabilities against other unpatched systems".

BlueStacks, the company whose software makes it possible to run Android games on Windows and macOS, has great news for gamers. It has announced a new BlueStacks Inside SDK which will make it easy for developers to bring their mobile games to Windows and deliver them through Steam.

Just as with the main BlueStacks software, this is not about emulating mobile devices. It's also not about porting games -- mobile games effectively become native PC games.

Medical testing firm and clinical laboratory Quest Diagnostics has revealed that a data breach has led to the records of nearly 12 million of its customers being exposed. The data includes financial data, Social Security numbers and medical information.

Quest Diagnostics was itself not the target of hackers, but the American Medical Collection Agency (AMCA) was. The company is used by Optum360 for billing collections services, and Optum360 is used by Quest Diagnostics.

Microsoft is refocusing its retail presence, taking the decision to close all of its remaining "speciality stores".

The last 17 in-mall kiosks have been closed with immediate effect, and Microsoft will now put its efforts into its growing chain of bricks-and-mortar retail stores around the world.

At WWDC yesterday, Apple made numerous announcements and one of the more interesting was the company's new alternative to social sign-in buttons. Endless apps and website let you sign in with your Facebook, Twitter or Google account for the sake of convenience, but it comes at the cost of privacy -- which is precisely why Apple came up with "Sign in with Apple".

The basic idea is the same as existing social sign-in options -- it's a quick and easy way to sign into various services without the need to create a dedicated account. The difference is that "Sign in with Apple" protects your privacy and avoids the tracking of the current crop of alternatives.

As announced a little over a year ago, US visa applicants should now expect to be asked for details of their social media accounts. Only certain types of diplomatic and official visa applications are exempt.

As of Friday, the US State Department started to use social media usernames, email addresses and phone numbers as part of its screening process. The use of "social media identifiers" for vetting purposes will apply to almost everyone applying for a US visa, raising all manner of privacy concerns.

Apple is due to kick off its Worldwide Developers Conference on Monday, and at the event the company is expected to kill off iTunes.

Having been with us for nearly two decades, it seems that the software everyone (well, a lot of people) loves to hate is finally being put out to pasture. At WWDC we should see Apple kill off iTunes, breaking it up into a number of individual apps for macOS, just as has happened on iOS.

Having already announced that PowerShell 7 will be the next version of PowerShell, Microsoft has released the first public preview. For the first time, PowerShell is based on .NET Core 3.0.

The command-line shell and scripting language is set to be updated on a monthly basis, so we can expect a few more preview versions before it hits general availability around a month after .NET Core 3.0. As well as releasing this first preview, Microsoft has also shared details of the PowerShell 7 roadmap.

Two weeks after warning about a critical Remote Code Execution vulnerability in Remote Desktop Services, Microsoft is concerned that around a million internet-connected computers remain unpatched and vulnerable to attack.

The company says that there is a risk that CVE-2019-0708, or BlueKeep, could turn into the next WannaCry if steps aren't taken to secure systems. While there is not yet any sign of a worm that exploits the vulnerability, proofs of concept do exist, and it could only be a matter of time before this changes. Microsoft is taking the matter so seriously, that it even released security patches for the unsupported Windows XP, Vista and 2003 -- people just need to install them.

Using code from the famous Mirai worm and the Azazel rootkit, HiddenWasp is a newly discovered malware strain targeting Linux systems.

HiddenWasp is slightly unusual in having Linux in its sights, and the targeted remote control tool is able to avoid detection by all major antivirus software. The malware is described as "sophisticated" as it comprises a deployment script, a trojan and a rootkit. This an  advanced backdoor attack tool that allows for complete remote control of a system.

Cloudflare's 1.1.1.1 DNS switching tool has proved very popular with iOS and Android users looking to take control of their internet connections, and there was much excitement when the company announced that it would be releasing a free VPN tool called Warp.

At the moment, there is a lengthy waiting list for the free VPN (I'm number 278100 on the list, for instance) but we've been given a sneak peak at what to expect. Leaked screenshots show off the free VPN, and a video gives you an idea of the sort of performance you can expect.

In a world that appears to be lurching ever further to the right, it is perhaps little wonder that white nationalists, white supremacists and other extremists are becoming more prevalent online. Social media sites have a balancing act to perform -- not wanting to be seen to be advocating censorship, but also removing troublesome elements from their networks.

And this is the problem that Twitter faces. The platform has long been home to a glut of racist content and users -- as well as other unsavoury material -- and now the site is conducting research to determine how best to tackle this. Specifically, it is looking at whether white nationalists and supremacists should simply be banned, or whether their posts should be left available for others to debate.

Apple has become more familiar with controversy than it might be entirely comfortable with in recent times. Once a near-untouchable company that could, in many people's eyes, do no wrong, there have been numerous scandals over the last few years -- legal battles, problematic hardware, canceled products, and accusations of anticompetitive behavior.

Faced with an antitrust legal battle after complaints of "monopolistic" practices in the App Store, Apple has launched a new site that appears to be a very public defense of what it stands accused of. The new "principles and practices" pages find Apple going out of its way, falling over itself to expose just how anticompetitive the App Store isn't. This is a company on the defensive.

Just days after the general release of openSUSE Leap 15.1, the WSL version of the distro has hit the Microsoft Store, opening up even more options for lovers of Linux on Windows 10.

Developer SUSE says that "openSUSE Leap 15.1 is the Windows Subsystem for Linux (WSL) distribution for professional developers, system administrators, entrepreneurs and Independent Software Vendors".

The Quake franchise is a gaming behemoth, and fans of the first-person shooter will soon be able to enjoy the re-released and revamped Quake II RTX. The RTX is a reference to ray tracing, and the game takes advantage of NVIDIA RTX graphics cards to power massively enhanced visuals.

Next Thursday, June 6, NVIDIA is releasing the remastered version of the game on both Windows and Linux -- and you can play it for free.
