We’ve all been there: Trying to clean out our inbox only to find that the same sketchy emails keep showing up, even after clicking “unsubscribe.” Robert from Danville, Virginia, wrote in with a question that many of us can relate to.

“When you unsubscribe to a junk email that you know you didn’t authorize, do you really unsubscribe and no longer get [emails]? I scroll to the bottom of the email and process the ‘unsubscribe’ function and even block the email using the block option within my email. Seems the same emails reappear. Is unsubscribing worth my time? Any remedies?” he wrote.

Robert, you’re not alone in asking this, and the trust is more complicated (and frustrating) than you might think. While unsubscribing can work in some cases, there are situations where it might actually make things worse. Let’s break down when it’s safe to unsubscribe, when it’s not and what you can do instead to take back control of your inbox.

The truth about unsubscribing from spam you didn’t sign up for

Unsubscribing isn’t always safe, especially with spam. If an email is from a legitimate business, like a store you bought something from or a newsletter you signed up for, it’s usually OK to unsubscribe. These companies are bound by email marketing laws and will typically remove you. However, emails that you never signed up for are completely different. Here are the key differences.

Legit email

Comes from a known business or service
Usually has a working unsubscribe link
Opt-out request is honored

Spam/scam email

Comes from unknown or random sources
“Unsubscribe” link might be fake or used to track clicks
Clicking may confirm your email is active and invite more spam

HOW TO STOP PROMOTIONAL EMAILS WHERE YOU CAN’T UNSUBSCRIBE

When not to click ‘unsubscribe’

Not all unsubscribe links are safe. In fact, clicking on one in a suspicious email can make things worse by signaling to spammers that your address is active.

Avoid clicking unsubscribe if:

The sender is unfamiliar, or the message feels unrelated to anything you’ve signed up for
The email contains typos, bad formatting or vague greetings like “Dear customer”
The sender address looks weird (e.g., winbignow@marketingzone.biz)
The “unsubscribe” link redirects to a strange URL

In these cases, clicking unsubscribe might invite even more junk mail instead of stopping it.

Better ways to fight spam

Here’s what you should do instead to counteract spam.

1) Mark it as spam or phishing: Every email provider (Gmail, Outlook, Yahoo, etc.) has a “report spam” button. Use it. This feature trains your inbox to recognize and filter future junk. It also helps others by flagging known spam sources all while not tipping off the spammer.

2) Block the sender (but know it’s temporary): Blocking a sender can help, but temporarily, because spammers often use rotating addresses. It’s a continuous game, but it still has short-term value.

How to block senders on major email platforms:

Gmail: Open the email > Click the three-dot menu > Block [sender]
Outlook: Open the message > Click the three-dot menu > Block or Report
Yahoo Mail: Open the email > Click the three-dot menu > Block sender
Apple Mail (iCloud): Tap the sender’s name > Block this Contact

3) Use your email’s built-in alias or disposable tools: Before switching to a third-party service, it’s worth checking what your current email provider already offers. Gmail, Outlook and Yahoo have handy tricks for separating junk from legit messages without signing up for anything new.

Here’s how it works with the major platforms.

Gmail: Add a plus sign (+) and a keyword to your regular address when signing up (e.g., yourname+shopping@gmail.com). The email will still arrive in your inbox, but now you can see who leaked your info and create filters to organize or block it.
Yahoo Mail (Plus users): You can create up to 500 disposable email addresses. These are full of alternate addresses that you can disable or remove if they start getting spammed.
Outlook: Microsoft lets you create and manage “alias” addresses linked to your existing Outlook account. These aliases can be used to send and receive email and help keep your primary address private.

This trick is great for organizing your inbox, tracking how your email is being used and filtering out spam before it becomes a problem. Check out the full how-to guide here: How to create a disposable email address.

4) Upgrade to a spam-killer inbox service: Anonymous email tricks are a smart move, but if you want full control over spam, privacy and organization, a dedicated alias email service is the way to go.

An alias email address is an additional address that forwards to your primary inbox. It lets you receive messages without ever exposing your real email. By using different aliases for online sign-ups, shopping, newsletters and more, you can easily manage incoming mail and instantly shut off spam by deleting an alias whenever needed.

Creating multiple aliases also protects your real email address from being flooded with junk or compromised in a data breach. It’s one of the easiest ways to stay organized and secure online.

YOUR EMAIL DIDN’T EXPIRE. IT’S JUST ANOTHER SNEAKY SCAM

5) Use a burner email service for short-term sign-ups: If you want an extra layer of separation from your personal inbox, burner email services are a great option. They create temporary email addresses you can use for quick sign-ups with no commitment and no spam in your real inbox.

Burner emails are especially useful for:

Free trials
Giveaways
Sketchy sites
One-time forms or downloads

You can refer to a comprehensive list of popular temporary email services that generate disposable addresses lasting from minutes to hours, which offer features like anonymous inboxes, attachment support, browser extensions and easy expiration to protect your privacy and reduce spam.

Kurt’s key takeaways

Unsubscribing from suspicious emails can do more harm than good, so it’s best to mark them as spam and block the sender instead. Use your email provider’s built-in tools to filter messages and create aliases to track where spam is coming from. For short-term sign-ups, disposable email services are a great way to protect your real inbox. And if you want long-term control and privacy, switching to a secure email service is the best way to keep your inbox clean.

Xiaomi 17 is a small(ish) phone with a big(ish) battery

Xiaomi 17 is a small(ish) phone with a big(ish) battery

Xiaomi has just given a global launch to two of its latest flagship phones, the Xiaomi 17 and 17 Ultra, along with a Leica-branded Leitzphone edition of the Ultra. There’s no sign, however, of the 17 Pro, which launched in China with an additional display mounted next to the rear cameras.

The 17 and 17 Ultra will apparently be available soon in the UK, Europe, and select other markets. The 17 — pitched as a rival to the likes of the iPhone 17 and Samsung Galaxy S26 — will cost £899 / €999 (about $1,200), while the larger and more capable Ultra starts from £1,299 / €1,499 ($1,750). The limited-edition Leitzphone will be substantially more expensive at £1,699 / €1,999 ($2,300), though it includes 16GB of RAM and 1TB of storage, along with a few extra accessories.

I like the simple, sleek aesthetic of the phone.

The 6.3-inch display isn’t tiny, but it does make the phone small by modern standards.

All three of the phone’s rear cameras are 50-megapixel.

The 17 is an extremely capable small-ish flagship, with a 6.3-inch OLED display, Qualcomm Snapdragon 8 Elite Gen 5, and large 6,330mAh silicon-carbon battery (though sadly smaller than the 7,000mAh version launched in China). I won’t be writing a full review of the 17, but did spend a week using it as my main phone, and found that the battery cruised past the full-day mark, though wasn’t quite enough for two full days of my typical usage. That’s far better battery life than you’d find in similarly sized phones from Apple, Samsung, or Google.

The cameras impress too, with 50-megapixel sensors behind each of the four lenses, selfie included. Pound for pound, you won’t find many better camera systems in any phone this size.

1/10

I’ve been largely impressed by the Xiaomi 17’s cameras.

The Ultra, unsurprisingly, takes things to another level. It’s much larger, with a 6.9-inch display, and weighs a hefty 218g. Despite that, the 6,000mAh is actually smaller, though I found it delivered pretty similar longevity.

The 17 Ultra is larger in just about every respect, but strangely has a smaller battery.

The enormous camera is, as ever for Xiaomi’s Ultra phones, the highlight. There are 50-megapixel sensors for each of the main, ultrawide, and selfie cameras, with a large 1-inch-type sensor behind the primary lens. The periscope telephoto is even more impressive: 200-megapixel resolution, a large 1/1.4-inch sensor, and continuous optical zoom from 3.2x to 4.3x, the equivalent of 75-100mm. Xiaomi isn’t the first to pull off a true zoom phone — Sony’s Xperia 1 IV got there first in 2022 — but the telephoto camera here is far more capable than that phone’s, with natural bokeh and impressive performance even in low light.

Photo of Xiaomi 17 Ultra Leitzphone outdoors

This is the Leica-branded Leitzphone version of the 17 Ultra.

The camera capabilities are supported by Xiaomi’s ongoing photography partner Leica, but it’s the pair’s Leitzphone that really emphasizes that. Slightly redesigned from the 17 Ultra Leica Edition that was released in China last December, this includes Leica branding across the hardware and software, a range of Leica filters and shooting styles, and a rotatable rear camera ring that can be used to control the zoom. It’s the first Leica Leitzphone produced by Xiaomi — after a trio of Japan-only Sharp models — and comes with additional branded accessories, including a case with a lens cap and a microfiber cleaning cloth.

Xiaomi has plenty of other announcements alongside the 17 series phones at MWC this year, including a super-slim magnetic power bank, the Pad 8 and Pad 8 Pro tablets, and a smart tag that supports both Google and Apple’s tech-tracking networks.

Google dismantles 9M-device Android hijack network

Google dismantles 9M-device Android hijack network

NEWYou can now listen to Fox News articles!

Free apps are supposed to cost you nothing but storage space. But in this case, they may have cost millions of people control over their own internet connections.

Google says it has disrupted what it believes was the world’s largest residential proxy network, one that secretly hijacked around 9 million Android devices, along with computers and smart home gadgets. Most people had no idea their devices were being used since the apps worked normally, and nothing looked broken.

But behind the scenes, those devices were quietly routing traffic for strangers, including cybercriminals.

STOP GOOGLE FROM FOLLOWING YOUR EVERY MOVE

How your device became part of a proxy network

According to Google’s Threat Intelligence Group, the network was tied to a company known as IPIDEA. Instead of spreading through obvious malware, it relied on hidden software development kits, or SDKs, that were embedded inside more than 600 apps. These apps ranged from simple utilities to VPN tools and other free downloads. When you installed one, the app performed its advertised function. But it also enrolled your device into a residential proxy network.

That means your phone, computer or smart device could be used as a relay point for someone else’s internet traffic. That traffic might include scraping websites, launching automated login attempts or masking the identity of someone conducting shady online activity. From the outside, it looked like that activity came from your home IP address. You wouldn’t see it happening, and in many cases, you wouldn’t notice any major performance issues.

Google says in a single seven-day period earlier this year, more than 550 separate threat groups were observed using IP addresses linked to this infrastructure. That includes cybercrime operations and state-linked actors. Residential proxy networks are attractive because they make malicious traffic look like normal consumer activity. Instead of coming from a suspicious data center, it appears to come from someone’s living room.

What Google did to shut it down

Google says it took legal action in a U.S. federal court to seize domains used to control the infected devices and route proxy traffic. It also worked with companies like Cloudflare and other security firms to disrupt the network’s command-and-control systems. Google claims it also updated Play Protect, the built-in Android security system, so that certified devices would automatically detect and remove apps known to include the malicious SDKs.

However, Google also warned that many of these apps were distributed outside the official Play Store. That matters because Play Protect can only scan and block threats tied to apps installed through Google Play. Third-party app stores, unofficial downloads and uncertified Android devices carry far greater risk.

IPIDEA has claimed its service was meant for legitimate business use, such as web research and data collection. But Google’s research suggests the network was heavily abused by criminals. Even if some users knowingly installed bandwidth-sharing apps in exchange for rewards, many did not receive clear disclosure about how their devices were being used.

Google’s investigation also found significant overlap between different proxy brands and SDK names. What looked like separate services were often tied to the same infrastructure. That makes it harder for consumers to know which apps are safe and which are quietly monetizing their connection.

7 ways you can protect yourself from Android proxy attacks

If millions of devices can be quietly turned into internet relay points, the big question is, how do you make sure yours isn’t one of them? These steps reduce the risk that your phone, TV box or smart device gets pulled into a proxy network without you realizing it.

1) Stick to official app stores

Only download apps from the Google Play Store or other trusted app marketplaces. Some apps hide small pieces of code that can secretly use your internet connection. These are often spread through third-party app stores or direct app files called “APKs,” which are Android app files installed manually instead of through the Play Store. When you sideload apps this way, you bypass Google’s built-in security checks. Sticking to official stores helps keep those hidden threats off your device.

2) Avoid “earn money by sharing bandwidth” apps

If an app promises rewards for sharing your unused internet bandwidth, that’s a major red flag. In many cases, that is exactly how residential proxy networks recruit devices. Even if it sounds legitimate, you are effectively renting out your IP address. That can expose you to abuse, blacklisting or deeper network vulnerabilities.

3) Review app permissions carefully

Before installing any app, check what permissions it requests. A simple wallpaper app should not need full network control or background execution privileges. After installation, go into your phone’s settings and audit which apps have constant internet access, background activity rights or special device permissions.

4) Install strong antivirus software

Today’s mobile security tools can detect suspicious app behavior, unusual internet activity and hidden background services. Strong antivirus software adds an extra layer of protection beyond what’s built into your device, especially if you’ve installed apps in the past that you’re unsure about. Get my picks for the best 2026 antivirus protection winners for your Windows, Mac, Android and iOS devices at Cyberguy.com.

5) Keep your devices updated

Android security updates patch vulnerabilities that proxy operators may exploit. If you’re using an older phone, tablet or Android TV box that no longer receives updates, it may be time to upgrade. Unpatched devices are easier targets for hidden SDK abuse and botnet enrollment.

6) Use a strong password manager

If your device ever becomes part of a proxy network or is otherwise compromised, attackers often try to pivot into your accounts next. That’s why you should never reuse passwords. A password manager generates long, unique passwords for every account and stores them securely, so one breach does not unlock your email, banking or social media. Many password managers also include breach monitoring tools that alert you if your credentials appear in leaked databases, giving you a chance to act before real damage is done. Check out the best expert-reviewed password managers of 2026 at Cyberguy.com.

7) Remove apps you don’t fully trust

Go through your installed apps and delete or uninstall anything you don’t recognize or haven’t used in months. The fewer apps running on your device, the fewer opportunities there are for hidden SDKs to operate. If you suspect your device has been compromised, consider a full reset and reinstall only essential apps from trusted sources.

Kurt’s key takeaway

Residential proxy networks operate in a gray area that sounds harmless on paper but can quickly become a shield for cybercrime. In this case, millions of everyday devices were quietly enrolled into a system that attackers used to hide their tracks. Google’s takedown is a major move, but the broader market for residential proxies is still growing. That means you need to be cautious about what you install and what permissions you grant. Free apps are rarely truly free. Sometimes, the product being sold is you and your internet connection.

Defense secretary Pete Hegseth designates Anthropic a supply chain risk

Defense secretary Pete Hegseth designates Anthropic a supply chain risk

This week, Anthropic delivered a master class in arrogance and betrayal as well as a textbook case of how not to do business with the United States Government or the Pentagon.

Our position has never wavered and will never waver: the Department of War must have full, unrestricted access to Anthropic’s models for every LAWFUL purpose in defense of the Republic.

Instead, @AnthropicAI and its CEO @DarioAmodei, have chosen duplicity. Cloaked in the sanctimonious rhetoric of “effective altruism,” they have attempted to strong-arm the United States military into submission – a cowardly act of corporate virtue-signaling that places Silicon Valley ideology above American lives.

The Terms of Service of Anthropic’s defective altruism will never outweigh the safety, the readiness, or the lives of American troops on the battlefield.

Their true objective is unmistakable: to seize veto power over the operational decisions of the United States military. That is unacceptable.

As President Trump stated on Truth Social, the Commander-in-Chief and the American people alone will determine the destiny of our armed forces, not unelected tech executives.

Anthropic’s stance is fundamentally incompatible with American principles. Their relationship with the United States Armed Forces and the Federal Government has therefore been permanently altered.

In conjunction with the President’s directive for the Federal Government to cease all use of Anthropic’s technology, I am directing the Department of War to designate Anthropic a Supply-Chain Risk to National Security. Effective immediately, no contractor, supplier, or partner that does business with the United States military may conduct any commercial activity with Anthropic. Anthropic will continue to provide the Department of War its services for a period of no more than six months to allow for a seamless transition to a better and more patriotic service.

America’s warfighters will never be held hostage by the ideological whims of Big Tech. This decision is final.
