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.

North Korean hackers use disguised apps to target Macs with hidden malware
Macs are safer than Windows PCs, but they’re not foolproof. Hackers occasionally find ways to infect Apple devices, and in most cases, we’re the ones who allow it. Since infiltrating Apple’s App Store is difficult, hackers trick people into downloading apps from third-party stores or random websites.
These apps look legitimate but are actually tools for infecting devices with malicious software. A recent incident highlights this issue, with North Korean hackers targeting Macs by hiding malware in seemingly harmless macOS apps.

How does the malware work?
Recent discoveries by Jamf Threat Labs have unveiled a sneaky form of malware targeting macOS computers. While it may sound technical, understanding the basics of how this malware operates can help you stay safe online.
This malware hides in seemingly harmless applications, such as a game called Minesweeper and a note-taking app referred to as a Notepad. These apps function as expected, but behind the scenes, they run malicious programs that could allow hackers to take control of your computer.
The apps use a technology called Flutter, a tool often used to create apps that work on multiple devices like phones and computers. Flutter makes it easier for app developers to design their software, but its unique structure also helps hackers hide their malicious code, making it harder for experts to detect.
Once installed, the malware connects to a remote server (think of it as a command center for hackers) to receive instructions. These instructions could include running commands on your computer without your knowledge. One trick this malware uses is running AppleScripts, a type of script built for macOS systems, which can quietly execute commands to steal your data or even control your device.
Even scarier, some versions of this malware had been signed and approved by Apple’s security system before experts caught on. This means the hackers were testing how far they could push their schemes without raising suspicion.

The North Korea connection
This malware isn’t just a random act of cybercrime, it has ties to tactics and techniques often associated with North Korean hackers. Experts have identified similarities between this malware and previous attacks linked to North Korea, including the use of certain coding methods and domains that the country’s cyber teams are known to exploit.
North Korea has a history of using cyberattacks to fund its operations or disrupt systems worldwide, often targeting financial systems or vulnerable individuals. In this case, the malware seems to be in the testing phase, potentially laying the groundwork for a larger attack in the future.
The apps containing the malware were designed to look harmless. These tactics suggest a focus on tricking people through social engineering, a method North Korean hackers have used in the past.
By embedding the malware within apps that appear useful or fun, the attackers can increase the chances of someone downloading and using the infected software. While this particular malware has not yet been linked to active attacks, its connection to North Korea’s cyber playbook is a strong indicator of potential risks ahead.

5 tips to protect yourself from Mac malware
1) Use reliable antivirus software: A strong antivirus program is your first line of defense against malicious links and malware that could steal your private information. Avoid clicking on random links, especially in emails or messages that claim to be urgent or demand updates. The best way to safeguard yourself from malicious links that install malware, potentially accessing your private information, is to have antivirus software installed on all your devices. It can also warn you about phishing emails and ransomware scams, helping to keep your personal data and digital assets safe. Get my picks for the best 2024 antivirus protection winners for your Windows, Mac, Android and iOS devices.
2) Be careful with downloads and links: Only download apps from trusted sources like the Mac App Store or official websites of known developers. Hackers often disguise malware as legitimate updates or harmless apps.
3) Keep your software up to date: Regular updates for macOS and installed apps are essential because they patch security flaws. Apple frequently rolls out updates to address vulnerabilities, so enabling automatic updates ensures you stay protected without the hassle of manually checking for them.
4) Use strong, unique passwords: A strong password can help keep your Mac safe from unauthorized access. Avoid reusing passwords across different accounts. A password manager can be incredibly helpful here—it generates and stores complex passwords for you, making them difficult for hackers to crack.
It also keeps track of all your passwords in one place and automatically fills them in when you log into accounts, so you don’t have to remember them yourself. By reducing the number of passwords you need to recall, you’re less likely to reuse them, which lowers the risk of security breaches. Get more details about my best expert-reviewed Password Managers of 2024 here.
5) Enable two-factor authentication (2FA): Activate 2FA for key accounts like your Apple ID, email, and financial services. This adds a second layer of security, making it much harder for attackers to access your accounts—even if they have your password.
HOW TO REMOVE YOUR PRIVATE DATA FROM THE INTERNET
Kurt’s key takeaway
I’ve noticed a significant rise in malware hiding in seemingly harmless apps, whether it’s related to Mac, Windows, Android, or even iPhones. It just shows that no device is completely safe, not even one made by Apple. Hackers, including those backed by North Korea, are constantly finding new ways to trick users into downloading malicious software. These attacks often fly under the radar because they look like regular, safe apps. With these threats becoming more sophisticated, it’s more important than ever to stay aware of the risks and be cautious about what you download and click on.

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.
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
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 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.
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.

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.

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.
