This post explains how to remove additional users and accounts from your Mac

There will be times when you need to remove a user from a device. In this article we’ll show you how to remove a user from a Mac.

For a better understanding it’s good to understand the difference between an actual user of the device and a “sharing only user.” On a Mac, you can use Sharing Only User settings to create a user that has access to your files and folders over the network. You can also use these settings to limit their access to your shared information and system.

Both have very similar ways of removal:

*   Apple menu > **System Settings**
*   Click **Users & Groups** in the sidebar. (You may need to scroll down.)
*   Click the **Info** button next to the user or group you want to delete, then click **Delete User** or **Delete Group**. Note: If a user is logged in to this Mac now, you can’t select them.

This will delete sharing users immediately. For other users you’ll have to decide what you want to do with their Home folder first. You can delete it, keep it, or save it in a disk image.

*   To save it in a disk image, select **Save the home folder in a disk image**, then click **Delete User**. This archives all the user’s documents and information so the user can be restored later if needed. The disk image is saved in _/Users/Deleted Users/_.
*   To leave the user’s home folder as is, select **Don’t change the home folder**, then click **Delete User**. The user’s documents and information are saved and the user can be restored later if needed. The Home folder remains in _/Users/_.
*   To remove the user’s home folder from the computer: Select **Delete the home folder**, then click **Delete User**. The user’s folder will be deleted.

If you don’t delete a user’s home folder, you can restore the user and the contents of the home folder. (A sharing-only user doesn’t have a home folder.)

This post explains how to remove additional users and accounts from your Windows device

There will be times when you need to remove a user from a device. In this article we’ll show you how to remove a user from Windows 10 or 11.

On Windows you can create a local user account (an offline account) for anyone who will frequently use your PC. But the best option in most cases, is for everyone who uses your PC to have a Microsoft account. With a Microsoft account, you can access your apps, files, and Microsoft services across your devices.

Should you want to remove an additional user account from Windows 10 or 11, you can:

*   Select **Start** \> **Settings** \> **Accounts** \> **Family & other users.** 
*   Under **Other users**, select the flyout for the account you want to remove.
*   Next to **Account and data**, select **Remove**. Note: this will not delete their Microsoft account, it will just remove their sign-in info from your Windows device.

Please note that Windows devices can have more than one administrator account. A user with an administrator account can access everything on the system, and any malware they encounter can use the administrator permissions to potentially infect or damage any files on the system. Only grant that level of access when absolutely necessary and to people you trust.

 How to remove a user from a shared Windows device 

This week on Lock and Code, we talk about what people lose when they let AI services make choices for dinners, reservations, and even dating.

_This week on the Lock and Code podcast…_

The irrigation of the internet is coming.

For decades, we’ve accessed the internet much like how we, so long ago, accessed water—by traveling to it. We connected (quite literally), we logged on, and we zipped to addresses and sites to read, learn, shop, and scroll. 

Over the years, the internet was accessible from increasingly more devices, like smartphones, smartwatches, and even smart fridges. But still, it had to be accessed, like a well dug into the ground to pull up the water below.

Moving forward, that could all change.

This year, several companies debuted their vision of a future that incorporates Artificial Intelligence to deliver the internet directly to you, with less searching, less typing, and less decision fatigue. 

For the startup Humane, that vision includes the use of the company’s AI-powered, voice-operated wearable pin that clips to your clothes. By simply speaking to the AI pin, users can text a friend, discover the nutritional facts about food that sits directly in front of them, and even compare the prices of an item found in stores with the price online.

For a separate startup, Rabbit, that vision similarly relies on a small, attractive smart-concierge gadget, the R1. With the bright-orange slab designed in coordination by the company Teenage Engineering, users can hail an Uber to take them to the airport, play an album on Spotify, and put in a delivery order for dinner.

Away from physical devices, The Browser Company of New York is also experimenting with AI in its own web browser, Arc. In February, the company debuted its endeavor to create a “browser that browses for you” with a snazzy video that showed off Arc’s AI capabilities to create unique, individualized web pages in response to questions about recipes, dinner reservations, and more.

But all these small-scale projects, announced in the first month or so of 2024, had to make room a few months later for big-money interest from the first ever internet conglomerate of the world—Google. At the company’s annual Google I/O conference on May 14, VP and Head of Google Search Liz Reid pitched the audience on an AI-powered version of search in which “Google will do the Googling for you.”

Now, Reid said, even complex, multi-part questions can be answered directly within Google, with no need to click a website, evaluate its accuracy, or flip through its many pages to find the relevant information within.

This, it appears, could be the next phase of the internet… and our host David Ruiz has a lot to say about it.

Today, on the Lock and Code podcast, we bring back Director of Content Anna Brading and Cybersecurity Evangelist Mark Stockley to discuss AI-powered concierges, the value of human choice when so many small decisions could be taken away by AI, and, as explained by Stockley, whether the appeal of AI is not in finding the “best” vacation, recipe, or dinner reservation, but rather the best of anything _for its user_.

> “It’s not there to tell you what the best chocolate chip cookie in the world is for everyone. It’s there to help you figure out what the best chocolate chip cookie is for you, on a Monday evening, when the weather’s hot, and you’re hungry.”

Tune in today to listen to the full conversation.

**Listen up—Malwarebytes doesn’t just talk cybersecurity, we provide it.**

Protect yourself from online attacks that threaten your identity, your files, your system, and your financial well-being with our exclusive offer for Malwarebytes Premium for Lock and Code listeners.

 Your vacation, reservations, and online dates, now chosen by AI: Lock and Code S05E11 

Having real-time protection is like having guards stationed all around your castle, ready to defend. Here's how it works.

The constant barrage of cyber threats can be overwhelming for all of us. And, as those threats evolve and attackers find new ways to compromise us, we need a way to keep on top of everything nasty that’s thrown our way. 

Malwarebytes’ free version tackles and reactively resolves threats already on your system, but the real-time protection you get with Malwarebytes Premium Security goes one step further and actively monitors your computer’s files, processes, and system memory in real time to block threats before they have a chance to do any damage. You don’t need to worry about what happens after your initial scan, because real-time protection is actively waiting to combat new threats and keep you safe. 

Imagine your computer is like a castle, and you want to protect your people from potential invaders. Having real-time protection is like having guards stationed all around your castle, constantly watching for signs of trouble and stopping them in their path before they can cause harm. 

Here’s how guarding that castle looks like in cybersecurity terms: 

**1\. Proactive and continuous monitoring**

We monitor your files, processes, and system memory, your incoming and outgoing data, and the behavior of applications on your system. All in real time. 

**2\. Dynamic detection**

Unlike traditional approaches that rely heavily on detecting malware that is already known to exist, Malwarebytes employs dynamic detection techniques, such as heuristic analysis, behavior monitoring, and machine learning to detect and block threats based on their behavior and characteristics, even if the threats have never been seen before.  

**3\. Multi-layered defense**

Malwarebytes real-time protection offers a multi-layered approach to security, combining various technologies to provide comprehensive protection against a variety of threats. This includes protection against viruses, ransomware, potentially unwanted programs (PUPs), spyware, trojans, exploits, and other forms of malware.  

**4\. Rapid response** 

When Malwarebytes detects suspicious activity or potential threats, it responds quickly. Malwarebytes quarantines or removes malicious files, protects you from harmful websites, and blocks unauthorized access to your system.  

**5\. Minimal impact** 

Malwarebytes runs quietly in the background and protects you without hogging your device’s resources.  

**6\. Regular updates to malware detection database** 

To ensure our program is equipped to detect and block the latest threats, we continuously update our database and algorithms.  

In short, real-time protection serves as a proactive defense layer against constantly evolving cyber threats. Having this layer improves your cybersecurity and gives you peace of mind in this increasingly digital world.  

Don’t just take our word for it: Malwarebytes Premium Security was awarded “Product of the Year” in a recent AVLab test. 

Keep yourself protected and upgrade to Malwarebytes Premium Security.

 What is real-time protection and why do you need it?  

The Securities and Exchange Commission has announced rules around breaches for certain financial institutions.

The Securities and Exchange Commission (SEC) has announced rules around breaches for certain financial institutions—registered broker-dealers, investment companies, investment advisers, and transfer agents— that require them to have written incident response policies and procedures that can be used in the event of a breach.

The requirement is an adoption of amendments to Regulation S-P, which was enacted in 2000 to safeguard the financial information of consumers, requiring financial institutions to tell customers about how they use their personal information.

But things have changed drastically since 2000. Even in the four years between 2018 and 2022, complaints about identity theft more than doubled, per the FBI’s Internet Crime Complaint Center.

SEC Chair Gary Gensler said:

> “Over the last 24 years, the nature, scale, and impact of data breaches has transformed substantially. These amendments to Regulation S-P will make critical updates to a rule first adopted in 2000 and help protect the privacy of customers’ financial data. “

Under these amendments, covered firms will be required to notify customers of breaches that might put their personal data at risk. This will give these customers the chance to prepare themselves for the negative consequences of a breach.

Covered organizations have to provide notice to victims as soon as possible and no later than 30 days after becoming aware of an incident involving the leak of customer information. Organizations must include details about the incident, the data leaked and what victims can do to protect themselves. As Gensler puts it:

> “The basic idea for covered firms is if you’ve got a breach, then you’ve got to notify.”

The amendments will become effective 60 days after publication in the Federal Register. Larger entities will have 18 months after the date of publication in the Federal Register to comply with the amendments, and smaller entities will have 24 months after the date of publication in the Federal Register to comply.

May 13, 2024 - A list of topics we covered in the week of May 6 to May 12 of 2024

 A week in security (May 13 &#8211; May 19) 

iOS users are reporting that photos they had deleted long ago suddenly showed up again after this week's 17.5 update.

iPhone owners are reporting that photos they’d deleted are now back on their phones, after updating to iOS 17.5.

With so many users reporting similar oddities, it would seem something went wrong, or at least different than to be expected. Here are some examples from Reddit:

> “When in conversation with my partner, I went to send a picture and saw that the latest pictures were nsfw material we’d made years ago”

> “I have four pics from 2010 that keep reappearing as the latest pics uploaded to iCloud. I have deleted them repeatedly.”

> “Same thing happened to me. Six photos from different times, all I have deleted. Some I had deleted in 2023.”

When you delete a photo from an iPhone or iPad, it goes into a “Recently deleted” album for up to 30 days to make it easy to recover if the photo is accidentally deleted. However, the above examples vastly exceed this timeframe, and it’s unclear exactly what’s happened here.

When you delete a file, actually all that happens is you remove the pointer that tells you where exactly the file is located. This makes it hard to find, but not impossible. Until the system uses the location of the deleted file and replaces it with other data, the file can be retrieved.

Apple’s last update for iOS 17.5 and iPadOS 17.5 came out on Monday with a warning to update your iPhone as soon as possible. That’s because iOS 17.5 fixes 15 security vulnerabilities, some of which are serious. Please don’t let this article stop you from installing the update, but it’s good to be prepared for some unexpected behavior.

At the time of writing, Apple hasn’t commented on the issue.

Phishers are using new authentication-in-the-middle techniques to dupe victims into providing their login and MFA credentials.

More and more websites and services are making multi-factor-authentication (MFA) mandatory, which makes it much harder for cybercriminals to access your accounts. That’s a great thing. But as security evolves, so do cybercriminals who are always looking for new ways to scam us.

A type of phishing we’re calling authentication-in-the-middle is showing up in online media. While these techniques, named after man-in-the-middle (MitM) attacks, have existed for a while, they appear to be gaining traction now.

It works like this: A user gets lured to a phishing site masquerading as a site they normally use, such as a bank, email or social media account. Once the user enters their login into the fake site, that information gets redirected by the cybercriminals to the actual site, without the user knowing.

The user is then prompted for their MFA step. They complete this, usually by entering a code or accepting a push notification, and this information is then relayed to the criminals, allowing them to login to the site.

Once the criminals are into an account, they can start changing settings like the account’s email address, phone number, and password, so the user can no longer log in, or they can simply clean out a bank account. This may help you understand why many platforms ask for your PIN or other authentication again when you try to change one of these important settings.

Victims are lured to phishing sites like these via links from social media or emails where it can be hard to identify the real link.  Phishing sites can even show up in sponsored search results, in the same way as we reported about tech support scams.

**How to protect yourself from authentication-in-the-middle attacks**

*   **Keep your wits about you**. Being aware of how scammers work is the first step to avoiding them. Don’t assume sponsored search results are legit, and trust that if something seems suspicious then it probably is.
*   **Use security software**. Many security programs block known phishing sites, although domains are often short-lived and get rotated quickly. Malwarebytes Browser Guard can help protect you.
*   **Use a password manager**. Password managers will not auto-fill a password to a fake site, even if it looks like the real deal to you.
*   **Consider passkeys.** Multi-factor authentication is still super-important to enable, and will protect you from many types of attacks, so please continue to use it. However, authentication-in-the-middle attacks only work with certain types of MFA, and passkeys won’t allow the cybercriminals to login to your account in this way. Many services have already begun using passkeys and they’re no doubt here to stay.

 Scammers can easily phish your multi-factor authentication codes. Here&#8217;s how to avoid it 

Data breach marketplace BreachForums has been seized by law enforcement agencies.

BreachForums—probably the largest dark web marketplace for stolen data to be leaked and sold—has been seized by law enforcement.

Now, both the regular and the TOR domain of BreachForums are plastered with a message telling visitors the site is now under control of the FBI.

The FBI said BreachForums and its predecessor Raidforums was:

> “…operating as a clear-net marketplace for cybercriminals to buy, sell, and trade contraband, including stolen access devices, means of identification, hacking tools, breached databases, and other illegal services.”

Raidforums ran from early 2015 until February 2022. The first iteration of BreachForums was then set up in March 2022 and ran until March 2023, when US law enforcement arrested the alleged operator, “Pompompurin”, in New York.

A new administrator then rose to the occasion and said they were working on a plan to get the forum through the problems caused by that arrest. But on March 21, 2023, the new administrator announced the decision to shut BreachForums down.

Another forum administrator going by the account name “Baphomet” then took over.

According to BleepingComputer, the FBI has also seized the site’s Telegram channel, with law enforcement sending messages to the channel on behalf of the forum’s operator “Baphomet”.

BreachForums was in use just last week for a big name breach when a cybercriminal put up for sale breached customer data taken from Dell between 2017-2024.

We’ll keep you posted on any new developments.

Google and Apple are pushing forward on industry guidelines to stop the sue of Bluetooth devices for unwanted tracking

Apple and Google have announced an industry specification for Bluetooth tracking devices which help alert users to unwanted tracking.

The specification, called Detecting Unwanted Location Trackers, will make it possible to alert users across both iOS and Android if a device is unknowingly being used to track them.

The alert would be pushed to the users device and would say “\[Item\] Found Moving With You.”

In many cases “\[Item\]” might well actually be an AirTag.

AirTags’ intended use is to let you easily track things like your keys, wallet, purse, backpack, luggage, and more. You can simply set it up with your iPhone, iPad, or iPod touch, attach it somewhere, and the AirTag will show up in your Find My app. However, AirTags have long been associated with this unwanted tracking, which is something Apple apparently did not foresee and has been working on to make this type of abuse harder.

Apple’s first step to discourage unwanted tracking was the “Tracking Notifications” option in the Find My app. This feature is available on iOS or iPadOS 14.5 or later.

Android introduced a similar “unknown tracker alert” to find trackers placed near you or in your belongings without your knowledge or consent.

With the new capability that both tech giants have pushed, users will now get the alert, regardless of the platform the device is paired with. If a user gets such an alert on their device, it means that someone else’s Bluetooth tracker is moving with them.

Android and iPhone users can view the tracker’s identifier, have the tracker play a sound to help locate it, and access instructions to disable it. Bluetooth tag manufacturers including Chipolo, eufy, Jio, Motorola, and Pebblebee have all said that future tags will be compatible.

Apple and Google will continue to work with the Internet Engineering Task Force via the Detecting Unwanted Location Trackers working group to develop the official standard for this technology.
