A disgruntled security researcher has revealed a one-click exploit that takes advantage of a macOS vulnerability to reveal all of the passwords stored in a Mac's keychain.

Linus Henze developed an exploit tool called KeySteal that uses a 0-day bug to extract keychain passwords on macOS Mojave and older. He stresses that neither root access nor administrator privileges are required, and no password prompts are generated by the tool. Henze is not going to help Apple to fix the problem because the company does not offer a bug bounty program for macOS.

Google+ is nearing the end of the line, and ahead of this Google has announced that its Notifications Widget is also to be killed off.

The widget -- which appears in the upper right-hand corner of various Google products including Gmail -- lets users know when there are notifications for various services such as Google Photos, Hangouts Chat and Google+. But when March rolls around, you'll have to rely on alerts for individual services instead.

Windows 7 may be creakingly old now, but it is still widely used. While large numbers of consumers have migrated to Windows 10, there are still plenty of organizations that are clinging to the old operating system out of a sense of nostalgia, an unwillingness to upgrade, lack of funds for upgrading, or legacy requirements.

As of January 14, 2020, Microsoft will no longer be providing support or security updates for Windows 7 -- apart from for those who are willing to pay for it. The company is offering up to three years of Windows 7 Extended Security Updates (ESU), and pricing has just been revealed.

In an increasingly-connected world where data is collected and shared, privacy has become ever-more important to people. If you are of that mind, you may have enabled the Do Not Track (DNT) setting in your web browser in the hope that it will stop the websites you visit from tracking your online activities. Bad news: it probably makes no difference whatsoever.

This might be something you knew already, but research by privacy-focused search engine DuckDuckGo -- which famously does respect DNT requests -- found than more than three-quarters of people were not aware of that that many sites ignore DNT settings.

Microsoft's in-house game development division has undergone a rebranding. Previously known as Microsoft Studios, the division's new moniker is Xbox Game Studios.

Made up of a total of 13 game studios purchased by Microsoft over the years, and the division's corporate vice president, Matt Booty, promises that they are all "working hard to deliver incredible exclusives, original IP and all-new chapters from your favorite franchises".

Facebook said some time ago that it would be bringing an "unsend" option to Facebook Messenger, giving users the ability to delete messages they change their mind about.

Today is the day this feature finally appears with the addition of a new "Remove for everyone" option. While this will be welcomed by Facebook Messenger users, it will not please everyone; as well as there being a time limit on when messages can be deleted, there is no stealth deletion option as all chat participants are informed when a message is removed.

It is a few months since Flickr announced major changes to its free accounts, and today is the day the impact starts to be felt.

Users unwilling to upgrade to a Flickr Pro account are now limited to storing 1,000 photos online, and any images above this number will be deleted starting today. Anyone who hasn't downloaded or backed up their photos risks losing them forever.

If you're experiencing problems downloading updates from Windows Update, don't worry -- it's not just you.

Windows 10 users started to complain about problems with Windows Update last week after their computers displayed the message "We couldn't connect to the update service". While it initially appeared to be an ISP-related DNS issue, the problem was later determined to be with Microsoft. Despite an apparent fix, many people are still unable to download updates.

The head of Instagram has announced plans to introduce "sensitivity screens" in the wake of concerns about the spread of photos of self-harm on the image-based social network.

Adam Mosseri says that Instagram will use image-blurring similar to that used on Facebook to hide graphic content. The move comes in the wake of the suicide of a British teenager, the parents of whom said self-harm images on Instagram were a contributing factor.

The ability to edit tweets is one of the most frequently requested features for Twitter. The most common reason for wanting to make edits is to fix typos, but concern has been voiced about the potential for an editing facility to be abused -- which perhaps explains Twitter's apparent reticence at rolling out such a feature without careful thought.

While tweet editing has yet to appear, there has long been speculation about how it could be implemented. In a move that is sure to fuel rumors that an edit function is just around the corner, Twitter chief Jack Dorsey has talked about how the feature could work.

The roll out of GDPR (General Data Protection Regulation) has changed the face of privacy and data protection for millions of people across Europe. The regulation not only grants people access to the personal data companies hold about them, but also controls how this data can be used and transferred.

Apple's Tim Cook has already voiced his support for GDPR and said that the rest of the world should implement similar regulation. Now he has been joined by Cisco in calling for data laws to be embraced by the US as they have been in Europe.

A number of British and European politicians have written to the UK home secretary, Sajid Javid, to complain about the government's EU Exit mobile app.

The app was created to enable EU citizens to apply for "settled status" in the UK in the wake of the referendum vote that saw the start of the Brexit process. The government stands accused of "digital discrimination" because the app is only available for Android devices -- and only relatively modern ones at that. iPhone users have been left out in the cold, as have those with older Android phones, adding to the stress and concern that already surrounds Brexit.

There are numerous problems associated with Facebook, but the two that are talked about most are privacy and the spread of "fake news". To help combat the dissemination of misinformation, the social network partnered with numerous companies and news outlets to fact-check stories.

One of these partners was Snopes, the site famous for debunking myths, urban legends and fake news. But now the site has announced that it is ending its partnership with Facebook, citing " the ramifications and costs of providing third-party fact-checking services".

Apple has issued an apology for the recently-discovered bug that made it possible to eavesdrop on people via FaceTime.

The company had promised that a software update would be delivered later this week, but the interim solution was to simply disable the group FaceTime feature server-side. Apple now says that the problem has been fully fixed, but a software update that re-enables the group function will not be issued until next week.

The end of Skype Classic (or Skype 7, if you prefer) has been on the cards for a while now, much to the annoyance of legions of users. Microsoft has been keen to encourage Classic users to migrate to Skype 8, but many have held out. Now Microsoft is forcing their hands.

When the company announced that support for Skype 7 and below was terminating at the beginning of November, Microsoft said that "you may be able to use older versions for a little while". Three months down the line, Skype Classic users are being forced into upgrading to Skype 8.
