From TikTok to trouble: How your online data can be weaponized against you

Let’s talk about something that’s becoming a real headache these days: your online presence and how it can come back to bite you. A stark example of this occurred when 20 teachers from Great Valley Middle School in Malvern, Pennsylvania, fell victim to student impersonations on TikTok using information found online. Yikes. It’s time we face the music: Sharing our lives online, especially on social media, is riskier than ever.

Social media platforms have become an integral part of our personal and professional lives. However, they also expose us to various risks that can have serious consequences. Sure, you can’t stop someone from trying to mess with your reputation, but you can make it a whole lot harder for them.

How your online data can sabotage your reputation and safety

Having your online reputation damaged can hurt your chances of something as small as making friends in a new neighborhood, to something much more serious, like landing the job you’ve always dreamed of.

According to a Career Builder study, every two out of three hiring managers screen candidates’ social profiles before hiring. But it gets worse. Other statistics reveal that more than half of recruiters rejected a candidate because of what they found on their social media. However, the risks of having your personal data online don’t stop there. The list includes:

  • Identity theft and fraud
  • Stalking and harassment
  • Doxxing and swatting
  • Scams and phishing attempts
  • Data breaches

These issues are more common than you might think. The Bureau of Justice Statistics (BJS) estimates that around 10% of Americans were victims of identity theft within the year prior to their research. For 1 in 5, it has happened at some point in their lifetime. A recent data breach at National Public Data – a data broker – might have exposed the Social Security numbers of every American. BJS further reports that 3.4 million Americans were stalked in one year and 69% of those cases involved the use of technology. And that only includes reported incidents. The FBI confirms that cyberstalking is on the rise. Being anonymous online isn’t just about comfort. It’s about safety. Fortunately, you can take steps to protect your personal information on the web.

HACKED, SCAMMED, EXPOSED: WHY YOU’RE 1 STEP AWAY FROM DISASTER ONLINE

Erase your digital footprint and protect your privacy

You’ve probably heard the saying, “Once you put something on the internet, it’s there forever.” But that’s not entirely true. Disappearing from the internet is possible, though it’s not easy, especially if you try to do it on your own. Fortunately, some professional services can help. These services not only assist in deleting your existing data but also help prevent new information from resurfacing online. Here’s what you can do to remove your digital footprint from the web.

1) Remove yourself from people search sites

If you want to take on the task yourself, you’ll need to be prepared to put in some work. Most of your data is stored on what’s called people search sites. These are large databases of personal information, with some containing more than 300 million individual records.

People search sites publish highly private information, starting with your contact details and extending to your family, colleagues and even your sexual orientation. That data is often used by scammers. And the less your information is out there, the more difficult it is for bad actors to exploit you. The good news is that you can request the removal of your personal data from these sites. Each site has its own process, but they generally follow a similar pattern:

  • Visit the people search site, e.g., Whitepages
  • Look for an opt-out form (often found in the site’s footer)
  • Search for your personal information and select your profile
  • Confirm your identity and wait for the data to be removed

2) Invest in professional data removal services

It’s best not to leave anything to chance. While opting out from data brokers yourself is technically possible, the sheer number of brokers makes this a monumental task.

Moreover, protecting your privacy online isn’t a one-time effort. It requires continuous monitoring and frequent opt-out requests, as data brokers are constantly collecting personal information. Even if you successfully remove your profile, it could reappear later. Check out my top picks for data removal services here.

3) Remove yourself from Google search results

However, to fully protect yourself from cyberstalking, you also need to address the images associated with your online identity. If someone wants to hurt your reputation, knowing your name and home address might only be part of the puzzle. The other piece could be finding your images. Using personal details like your childhood home address, school or past employers, stalkers can unearth potentially damaging content and use it to harm your online reputation. But images aren’t the only thing you should address. If you want to leave no trace on Google, make sure to:

Advertisement
  • Remove your personal information and images from Google
  • Modify social media settings to be more private and delete old accounts (they will appear in search results)
  • Delete your trail of website comments
  • Blur your house on Google and Apple Maps

Unfortunately, you can’t remove content from Google search results directly. You can submit a removal request, but Google must approve it first. For more details, refer to my previous post on how to remove yourself from Google searches. If your request is denied, you’ll need to contact the site owner and ask them to take it down. However, your options here are limited. Once bad actors get hold of your data, it’s difficult to regain control. That’s why it’s so important to stop stalkers from accessing your information in the first place.

Additional tips to safeguard your online reputation

1) Be cautious about sharing personal information on social media. Adjust privacy settings to limit what’s publicly visible.

2) Monitor your digital footprint regularly. Set up Google Alerts for your name to stay informed about new mentions online.

3) Strengthen your passwords and enable two-factor authentication on all accounts to prevent unauthorized access. Also, consider using a password manager to generate and store complex passwords.

4) Exercise caution with links and attachments. Don’t click on suspicious links in social media posts, emails or messages as they may lead to phishing sites or malware downloads. Verify the source before opening any attachments, especially from unknown senders. When in doubt, contact the purported sender through a separate, trusted channel to confirm the legitimacy of the link or attachment. Additionally, use strong antivirus software and keep it updated to provide an extra layer of protection against potential threats.

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. This protection can also alert you to phishing emails and ransomware scams, keeping your personal information and digital assets safe.

Kurt’s key takeaways

From fake TikTok profiles to data breaches, it seems like our online presence is constantly under siege. But here’s the thing: While we can’t stop every bad actor out there, we can definitely make their job a lot harder. It’s all about taking control of your digital footprint. Whether it’s scrubbing yourself from people search sites, investing in professional data removal services or being more mindful of what we share online, there are steps we can take to protect ourselves. Remember, your online reputation isn’t just about social media likes; it can impact everything from job prospects to personal safety. So, maybe it’s time we all took a good hard look at our online presence and asked ourselves: Is it really serving us or is it leaving us vulnerable?

Polymarket has been allowing people to bet on when the US would strike Iran next. Obviously, now that it’s actually happened and people have died, the prediction betting market is feeling some pressure. The site has been at the center of controversy before, including suspicions of insider trading on the Super Bowl halftime show and the capture of Venezuelan President Nicolás Maduro.

In a statement posted on its site, Polymarket defended its decision to allow betting on the potential start of a war, saying that it was an “invaluable” source of news and answers, before taking shots at traditional media and Elon Musk’s X. The statement reads:

Google dropped dark web monitoring: Should you care?

Google dropped dark web monitoring: Should you care?

NEWYou can now listen to Fox News articles!

Google has officially discontinued its Dark Web Report feature, a free tool that once scanned known dark web breach dumps for personal information tied to a user’s Google account. The service delivered notifications when email addresses and other identifiers appeared in leaked datasets.

According to Google’s support page, the system ceased scanning for new dark web data Jan. 15, 2026, and the reporting function was removed entirely on Feb. 16, 2026, meaning users can no longer access the feature.

The company said the decision reflects a shift toward security tools it believes provide clearer guidance after exposure, rather than standalone scan alerts.

If you previously relied on the free dark web scan as an early warning signal for leaked data, this change removes one of your sources.

So what did users really lose?

Google’s Dark Web Report acted as a basic exposure scanner. It checked whether personal information linked to a Google account had surfaced in known breach collections circulating on the dark web.

When a match is found, users receive a notification identifying which type of data appeared in a leak. Depending on the data breach, that could include an email address, phone number, date of birth or other identifying details commonly harvested during large-scale hacks.

The report did not display stolen credentials or provide access to the leaked database itself. It also did not trace the origin of the compromise beyond referencing the breached service when available.

After an alert was issued, the next steps were left to the user. Google recommended actions such as changing passwords, enabling stronger authentication methods and reviewing account security settings. With the tool now removed, that automated breach check tied directly to a Google account is no longer available.

What you still have access to

Google directs users to its Security Checkup, a dashboard that scans your account for weak settings and unusual sign-in activity.

Its built-in Password Manager includes Password Checkup, which scans saved credentials against known breach databases and prompts you to change exposed passwords. Google also supports passkeys and two-factor verification to lock down account access.

The Results About You tool lets users search for personal information in Google Search and submit removal requests for certain publicly indexed details.

Alerts don’t always mean protection

Once personal information is compromised, it often ends up far beyond the breach itself. Stolen credentials and identity data are regularly trafficked on underground platforms where buyers can search for information tied to real people.

The BidenCash dark web marketplace was taken down by U.S. authorities in June 2025, and the Justice Department confirmed that the platform peddled stolen personal information and credit card data.

These illicit markets operate with a level of organization not unlike legitimate online stores. Search tools and bulk data sets are up for grabs and can be used to target any online account. This makes credential stuffing easier, where attackers test leaked passwords across multiple services in hopes of barreling into your account.

A breach alert tied to a dark web scan points to a leak at one moment in time; it does not follow whether that information has been sold to third parties or used in subsequent fraud attempts. For everyday users, this means that just knowing your data appeared in a leak doesn’t help much.

THINK YOUR NEW YEAR’S PRIVACY RESET WORKED? THINK AGAIN

Stolen personal information can circulate for years, making ongoing monitoring more important than a one-time alert.  (Kurt “CyberGuy” Knutsson)

Identity monitoring may be a better option

With Google’s scan gone, some people may consider dedicated identity protection services instead. Many of these services offer continuous monitoring of your personally identifiable information and send alerts about changes to your credit reports from all three major U.S. credit bureaus. That can include notifications about new inquiries, newly opened accounts and monthly credit score updates. Some plans also monitor a broader range of personal identifiers, such as driver’s license numbers, passport numbers and email addresses.

Beyond credit monitoring, certain services track linked bank, credit card and investment accounts for unusual activity. They may also monitor public records for changes to addresses or property titles and alert you if your information appears in those filings.

Many providers include identity theft insurance to help cover eligible out-of-pocket recovery costs. Coverage limits vary by plan and provider. Additional features often include spam call and message protection, a password manager, a virtual private network (VPN) and antivirus software.

No service can prevent every form of identity theft. However, ongoing monitoring and recovery support can make it easier to respond quickly if your information is misused.

Kurt’s key takeaways

Google’s decision to drop its Dark Web Report may seem small. But it removes a tool many users relied on. For some, those alerts were the first warning that their data appeared in a breach. That automatic scan is now gone. Google still offers Security Checkup, Password Checkup, passkeys and two-step verification. However, none of them actively scan dark web breach dumps for you. Stolen data does not disappear. Criminals copy, sell and reuse it. One alert shows a single moment. Ongoing identity theft monitoring helps you stay aware over time.

Now that Google has dropped its dark web monitoring feature, will you actively check your data exposure or assume someone else is watching it for you? Let us know your thoughts by writing to us at Cyberguy.com

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.

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.

Photo of Xiaomi 17 and 17 Ultra on a table, closeup on the cameras

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.
