Beware of TikTok’s danger that could be a malware menace to your life
TikTok is having a tough time, and hackers are working hard to add to its misery. A malicious code took over accounts on TikTok and compromised the official presence of celebrities and brands, including Paris Hilton and CNN.
The hackers behind this sent malware via direct messages (DMs) on the platform.
Users didn’t have to click any links or download any files to get hacked. Just opening the message was enough for a device to be infected.

What you need to know about TikTok DMs exploit
Hackers are apparently targeting high-profile TikTok accounts. So far, accounts from CNN, Sony and Paris Hilton have been targeted. CNN was the first account that got hacked, and it was reportedly down for several days after the incident.
The attack reportedly happens without the account owner needing to click on or open anything, known as a zero-click attack. All they need to do is open a DM, and the account can be taken over, leaving the rightful owner locked out. The vulnerability might lie in how content is processed when a DM is opened. Similar weaknesses have been identified before, such as vulnerabilities in the Chromium browser triggered by fabricated images.

We reached out to TikTok, and a spokesperson told CyberGuy, “Our security team is aware of a potential exploit targeting a number of high-profile accounts. We have taken measures to stop this attack and prevent it from happening in the future. We’re working directly with affected account owners to restore access, if needed.”
The hack appears to be a “zero-day” attack, which means the bad actors discovered the vulnerability in TikTok’s code before the developers did. TikTok had zero days to prevent it.

TikTok has a history of getting hacked
This is not TikTok’s first hacking incident. In 2023, over 700,000 accounts in Turkey were hacked because TikTok’s two-factor authentication system wasn’t secure enough. This all happened right before an important presidential election in Turkey, which made things even messier.
In 2022, security experts at Microsoft found a major flaw in the TikTok app. All it took was clicking a bad link and hackers could hijack your account.
Concerns about TikTok’s data security and its connection to ByteDance, its Chinese parent company, have also captured the attention of lawmakers. The U.S. government fears China uses the app to spy on Americans or to influence the messages they see. President Biden has even signed a bill forcing ByteDance to either sell its U.S. TikTok operations or face a ban in the country.

6 ways to protect yourself from TikTok DM danger
To make sure your TikTok account doesn’t get hacked by malicious DMs, follow these steps.
1. Use strong antivirus software to protect against phishing attempts: Stay vigilant when it comes to emails, phone calls or messages from unknown sources asking for personal information. Avoid clicking on suspicious links or providing sensitive details unless you can verify the legitimacy of the request.
The best way to protect yourself from clicking malicious links that install malware that may get access to your private information is to have antivirus protection installed on all your devices. This can also alert you of any phishing emails or ransomware scams. Get my picks for the best 2024 antivirus protection winners for your Windows, Mac, Android & iOS devices.
2. Use strong and unique passwords: Create strong passwords for your accounts and devices and avoid using the same password for multiple online accounts. Consider using a password manager to securely store and generate complex passwords. It will help you to create unique and difficult-to-crack passwords that a hacker could never guess. Second, it also keeps track of all your passwords in one place and fills passwords in for you when you’re logging into an account so that you never have to remember them yourself. The fewer passwords you remember, the less likely you will be to reuse them for your accounts. Get more details about my best expert-reviewed password managers of 2024 here.
3. Enable two-factor authentication: Enable two-factor authentication whenever possible. This adds an extra layer of security by requiring a second form of verification, such as a code sent to your phone, in addition to your password.
4. Keep your TikTok app up to date. Regularly update your TikTok app to avoid getting hacked. While you’re at it, update your antivirus software, web browsers and other applications to ensure you have the latest security patches and protections.
5. Review and adjust privacy settings: Ensure that your TikTok privacy settings are appropriately configured. Limit who can send you direct messages, comment on your videos and view your profile. This reduces the risk of unwanted interactions with potential hackers.
6. Monitor account activity: Regularly check your account activity for any unusual behavior or unauthorized access. TikTok provides a log of devices that have accessed your account. If you notice any unfamiliar devices, immediately change your password and log out of all devices. Also, to report suspicious activity on your account, TikTok provides channels to report a problem in its app.
HOW TO REMOVE YOUR PRIVATE DATA FROM THE INTERNET
Kurt’s key takeaways
TikTok needs to strengthen its system to ensure hackers don’t access users’ accounts. While the latest incident seems to be affecting celebrities and high-profile accounts, bad actors may also start targeting common users. Given these security concerns, it should come as no surprise that I advise against using TikTok, or at the very least, to use it with extreme caution. Meanwhile, be cautious. If someone messages you asking you to click on something or send them something, don’t just do it. Scammers love pressuring people to act fast. So, take a breath and think twice before you click.

Google’s Nest Thermostat has hit its best price of the year
If you’re looking for a relatively affordable way to cut down on cooling costs, Google’s Nest Thermostat can help. It’s packed with smart controls and energy-saving features, and right now it’s on sale in white for $79 ($50 off), which is its best price of the year, at Amazon.
The smart thermostat is quick to install and makes it easy to adjust your home’s temperature whether you’re relaxing in bed or on your way home thanks to the Google Home app. You can also create schedules and control it with your voice using Google Assistant, Alexa, or another Matter-compatible voice assistant.
Once it’s set up, the Nest Thermostat can automatically turn the temperature down when you’re away to help reduce unnecessary energy use, while Google’s Savings Finder feature suggests additional ways to save over time. It also monitors your HVAC system and can alert you if something doesn’t seem right, making it easier to stay on top of maintenance before small issues become bigger, more expensive ones. If you’re eligible, Nest Renew can also automatically shift some of your heating and cooling to times when electricity is cleaner or cheaper.
That said, this is Google’s entry-level model from 2020, so you do miss out on some of the premium features found on the latest Nest Learning Thermostat. Unlike the flagship version, it won’t learn your schedule automatically over time, for example, and lacks support for Nest Temperature Sensors that let you prioritize the temperature in a specific room. Even so, if all you want is an easy way to adjust your home’s temperature remotely and potentially lower your energy bills, the Nest Thermostat is still a solid investment at this price.

Medical identity theft follows you into the doctor’s office
NEWYou can now listen to Fox News articles!
The Justice Department recently charged 455 people in its annual National Health Care Fraud Takedown. The cases involve more than $6.5 billion in alleged false claims. More state Medicaid units took part than in any prior year. Ninety of the accused are doctors or other licensed medical professionals. The DOJ says prosecutors still must prove the charges in court.
Many schemes used other people’s medical identities. Prosecutors also added aggravated identity theft charges in cases across dozens of states. In one case, the co-owner of a Virginia mental health company allegedly paid homeless people with hotel stays. Prosecutors say the company used their Medicaid numbers, then billed Medicaid for crisis services the patients never got.
For the people whose numbers got used, the case file may eventually close. Their medical records may not be so easy to fix. Once someone else’s treatment shows up under your name, it can add wrong information to your chart. It can also use up insurance benefits you may need later. That is harder to undo than canceling a credit card.

DR OZ WARNS MEDICARE SCAMMERS ARE STEALING BILLIONS — AND YOUR PERSONAL INFORMATION COULD BE NEXT
Medical identity theft can put someone else’s claims, prescriptions or diagnoses into your health records, creating problems that can follow you into a doctor’s office. (iStock)
The identity thief’s treatment gets written into your file
Medical identity theft happens when someone uses your name, Social Security number (SSN), health insurance account number, or Medicare number to see a doctor, fill a prescription, buy medical equipment, or submit a claim, according to the Federal Trade Commission (FTC).
When care is billed under your name, the thief’s health information can blend into yours. The FTC warns that mixed records can affect the care you’re able to get and the benefits you are able to use. A blood type, a drug allergy, a diagnosis, or a prescription that belongs to a stranger can sit in the file a physician reads before treating you.
Data breaches can feed the market for medical identity theft
Hospitals and insurers hold the exact records that make the fraud work, and those records are stolen often. This does not mean every healthcare breach leads to fraud. However, it explains why your insurance number, Medicare number, SSN and medical records can become valuable long after a breach notice arrives.
This spring, NYC Health + Hospitals reported that an intruder had copied files that may have included health insurance information, medical information, biometric data, billing data and other personal information. The breach was later reported to affect roughly 1.8 million current and former patients and employees.
Once a name, SSN, insurance number, Medicare number or medical record reaches a criminal marketplace, it can be resold to operators who bill under someone else’s identity.
Treat your insurance card like a credit card
Your health insurance and Medicare numbers are what these operations need, so the FTC recommends guarding them the way you would a payment card.
- Keep enrollment forms, benefit statements, and prescription labels somewhere secure, and shred them before throwing them out.
- When a doctor’s office asks for your SSN, ask whether it can use another identifier or the last four digits instead.
- Be wary of anyone who calls, texts, or emails offering free braces, genetic tests, or medical supplies in exchange for your Medicare number; several of the schemes in the June takedown billed Medicare for exactly those items.
- If you are on Medicare, create or log in to your secure Medicare account and review your claims. You can also check your Medicare Summary Notice for services, supplies or equipment you do not recognize. If something looks wrong, call 1-800-MEDICARE.

Your credit report may never flag this fraud
Because a fraudulent medical claim runs through insurance and provider systems instead of a credit check, it skips the alerts most people rely on.
Here’s what the FTC says you should look out for:
- A bill or an Explanation of Benefits (EOB) statement for care you never received
- A call from a debt collector about a medical debt you do not owe
- A medical collection you do not recognize on your credit report
- A notice from your insurer that you have reached your benefit limit
- A Medicare Summary Notice that lists services, supplies or equipment you never received
What to do first if a medical claim looks wrong
If a bill, EOB or Medicare notice shows care you never received, move quickly and keep everything in writing.
1) Call your insurer or Medicare directly
Call your insurer or Medicare using the number on your card, not a number from a random text, email or voicemail.
2) Get the claim details
Ask for the provider name, date of service, claim number and service details.
3) Request the records in writing
Contact the provider in writing and request the medical or billing records tied to that claim.
4) Report the error
Report the error to your insurer’s fraud department.
5) File an identity theft report
File a report at IdentityTheft.gov if your medical identity was used. That gives you a recovery plan and documentation you may need if fraudulent bills or collections show up later.
6) Save every document
Keep copies of every bill, EOB, letter, portal message, police report and case number.
Correcting a medical file is slower than disputing a charge
Request your records from every provider, clinic, pharmacy, lab and insurer the thief may have used, then report each error in writing. Under HIPAA, a provider generally has 30 days to give you access to your records after a written request, with a possible 30-day extension.
Fixing the record itself can take longer. HHS says a covered provider or health plan usually has up to 60 days to act on a request to amend a medical record, with a possible 30-day extension in certain cases. If the provider or plan created the wrong information, it must amend inaccurate or incomplete information.
There’s one catch, though: a provider may refuse to release records that now contain a stranger’s information, citing that person’s privacy. If that happens, ask for the provider’s privacy officer or patient advocate. You can also file a complaint with the U.S. Department of Health and Human Services Office for Civil Rights if you do not get your records or an explanation within the required window.

A credit freeze alone won’t stop a claim under your insurance
A freeze blocks new accounts, but it does nothing about a claim filed with your insurance number. Because medical identity theft can move without touching your credit file, monitoring where your personal information appears is the earliest way to act on it.
An identity theft protection service can monitor the dark web, data broker sites and people-search sites for exposed SSNs, driver’s license numbers, medical ID numbers and email addresses. It can also track all three credit bureaus for medical collections that may follow and flag public-record changes tied to your name.
If misuse happens, some services include fraud resolution support to help you request records, dispute fraudulent claims and work with providers, insurers and credit bureaus. Some plans also include identity theft insurance for eligible recovery costs.
No service can prevent every misuse of your medical identity. However, ongoing monitoring may flag exposed information before another person’s treatment reaches your records and your insurance.

Kurt’s key takeaways
Medical identity theft hits in a place most of us rarely check: our health records. A stolen credit card can usually be canceled quickly. A stolen Medicare or insurance number can create fake claims, wrong diagnoses and benefit headaches that follow you long after the fraud case ends. I would not wait for a credit alert here. Check your EOBs, Medicare Summary Notices and insurer portals for visits, prescriptions or equipment you never received. Also, treat your insurance card like a payment card. Do not give the number to anyone who calls, texts or emails out of nowhere with a free offer. The most important thing is to act fast. Call your insurer or Medicare, ask for the claim details and request your medical records in writing. Then file at IdentityTheft.gov, so you have the paperwork you need if fraudulent bills or collections show up later.

Meta is reportedly working on smart glasses that would be recording all the time
Meta might be the next company to make an always-on AI wearable. The company is working on prototype “super sensing” always-aware smart glasses that could continuously record audio and snap photos “every few seconds,” according to the Financial Times. The wearer could then ask Meta AI about the captured audio and images.
However, the images and audio might not be directly available to the user. Here’s how the FT describes one way the glasses could use the data:
In one proposed system, raw footage and audio would not be stored by Meta or made available to the user, several people said. Instead, the metadata from that audio and images would be extracted and uploaded to the server for Meta’s AI to query, which proponents argue would have fewer privacy implications.
But currently, Meta is planning for the LED recording indicator to remain off in “super sensing” mode, the FT reports. In a July 2025 whitepaper, the company said that it would reserve the LED indicator for “active capture” scenarios where the user is saving photos or videos, and leave it off during “AI Feature” use — such as scanning a menu — to avoid users becoming too used to the indicator. (If the indicator was on during the “super sensing” mode, it might also be harder to know when the glasses are actually recording video.)
Meta is also discussing if it would use the captured data for training its AI models. It may also bring the “super sensing” features to glasses it has already released, the FT says.
“While we don’t comment on internal prototypes, we’re committed to getting our glasses right because they need to be loved by both people wearing them and those around them,” Meta spokesperson Dave Arnold says in a statement to The Verge. Arnold also notes that “Our approach has been to develop new technologies that will help people throughout their day, with privacy built in from the ground up.”
Meta hasn’t been shy about some type of always-aware glasses being a possibility. CEO Mark Zuckerberg, in the company’s Q1 2026 earnings call, said that he was “really excited to see the glasses evolve from being able to answer questions to being able to be a personal agent that’s with you all day long, helping you remember things and achieve your goals.” In a March blog post about new Ray-Ban Meta glasses, the company wrote that “with ongoing software updates, Meta AI on glasses will transition from something you have to prompt with a question each time, to a more continuous, in-the-moment assistant that can help throughout the day.”
