Steps to protect yourself while shopping on your phone this holiday season

The holiday season is the best time of the year. Many of us spend quality time with our families, enjoy delicious food and even go on vacations. For many, it’s also a time to indulge in shopping. And why not? This is when you find the best deals on your favorite products, whether it’s a new electronic gadget or a household essential.

However, the holiday season also comes with an increased risk of mobile fraud while shopping online. Scammers often target online shoppers in more ways than you might imagine. Fortunately, with some awareness and precautions, you can protect yourself. Below, I’ll discuss the rise in mobile shopping scams and how you can stay safe.

The rise in mobile fraud

According to Appdome’s latest U.S. Consumer Survey, 60.6% of Americans say fraud is their biggest concern. More than 40% of global consumers reported that they or someone close to them had been directly affected by mobile fraud, malware or a cyberattack. With mobile apps now being the main way people interact with brands, skepticism among users is growing. In fact, 24% of consumers believe developers don’t care about app security, a massive jump of 258% since 2021.

Social engineering has become a major worry, as people are becoming more aware of the many ways mobile fraud can happen. This includes things like location spoofing, scams that manipulate users and account takeovers. Almost half of the survey respondents this year said they or someone they know personally had dealt with fraud, scams or similar issues.

Such scams also affect your online shopping experience. I spoke with Tom Tovar, CEO of Appdome, regarding what consumers need to know when they are shopping on their mobile devices this holiday season.

“Consumers should be aware of phishing, smishing and vishing scams, which exploit fake emails, deceptive SMS messages and fraudulent phone calls to steal sensitive information. More sophisticated threats include FaceID bypass attacks, such as those carried out by the GoldPickaxe malware, which uses AI-enhanced techniques to bypass biometric authentication,” Tovar said.

“Other significant risks include banking trojans, which infiltrate apps to steal login credentials or financial data, and accessibility malware, which exploits device accessibility features to take control of mobile interactions. The rise of these sophisticated threats highlights the need for robust in-app security.”

4 steps to take to protect yourself while shopping on your phone

Shopping scams are becoming harder to detect, but it’s easy to stay ahead of them. Here are some steps you can take to protect yourself while shopping on your phone.

1) Shop on a safe mobile app

This might seem obvious, but sticking to trusted apps can help keep you safe while shopping. By trusted apps, I mean platforms like Amazon, eBay and Walmart.

“With the growing sophistication of mobile threats, it’s becoming increasingly challenging for consumers to identify risks independently. Threats like phishing, accessibility malware and banking trojans are designed to mimic legitimate functions, making them nearly impossible to detect at a glance. Instead of relying solely on spotting issues, consumers should look for apps that clearly communicate their commitment to security through visible privacy policies, transparent security practices and updates addressing new threats. Choosing apps from trusted sources and reading user reviews can also provide reassurance,” Tovar said.

2) Watch out for phishing, smishing and vishing scams

When shopping on your phone, be cautious of phishing, smishing and vishing scams, as they are common tactics used to steal your personal and financial information. Phishing involves fake emails that look like they are from trusted retailers, tricking you into sharing sensitive details like passwords or payment information. Smishing is a similar tactic but delivered through text messages, often containing links to fake websites or malicious downloads.

Vishing, on the other hand, involves scammers making phone calls pretending to be customer service representatives from well-known brands, attempting to gain access to your private information. Always verify the authenticity of emails, texts or calls before clicking links or sharing details to ensure a safe shopping experience.

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.

3) Be cautious about the permissions you grant to apps

When shopping online on your phone, it’s important to be careful about the permissions you give to apps. A lot of apps may ask for access to things like your camera, contacts or location, even if it’s not necessary for the shopping experience. Always think twice before granting these permissions.

“These permissions are often abused by malware to collect sensitive data or perform unauthorized actions. Before granting permissions, consider whether they align with the app’s purpose. Developers can mitigate these risks by incorporating protections from Appdome’s anti-fraud offering, which protects against the many abuse methods used by malicious actors to abuse mobile app permissions,” Tovar said.

4) Protect your financial information

Protecting financial information is crucial, especially when shopping online. It’s important to use secure websites, indicated by “https” in the URL, and avoid saving payment details in apps or on websites unless they are trustworthy.

While consumers should stay vigilant – by using trusted apps, downloading only from official app stores and monitoring for suspicious activity – there’s only so much they can do, Tovar said.

“The sophistication of modern threats often makes it impossible for users to identify or prevent all risks on their own,” he said. “Consumers have a better chance of keeping their personal information secure by choosing brands that prioritize security and back it up with tangible actions, such as automating robust protections and delivering proactive, built-in security measures.”

Kurt’s key takeaway

The holiday season is a prime time for shopping and, unfortunately, for scams. As mobile shopping continues to grow, threats like AI-driven scams and advanced malware are expected to increase. However, you can keep yourself safe by staying informed about potential threats, choosing apps with robust security measures and practicing good mobile hygiene. It’s also the responsibility of app developers to ensure users don’t fall prey to scammers.

Grubhub confirms data breach amid extortion claims

NEWYou can now listen to Fox News articles!

Food delivery platform Grubhub has confirmed a recent data breach after unauthorized actors accessed parts of its internal systems.

The disclosure comes as sources tell BleepingComputer the company is now facing extortion demands linked to stolen data.

In a statement to BleepingComputer, Grubhub said it detected and stopped the activity quickly.

“We’re aware of unauthorized individuals who recently downloaded data from certain Grubhub systems,” the company said. “We quickly investigated, stopped the activity, and are taking steps to further increase our security posture.”

Grubhub added that sensitive information, such as financial details or order history, was not affected. However, the company declined to answer follow-up questions about when the breach occurred, whether customer data was involved or if it is actively being extorted.

What Grubhub has confirmed so far

While details remain limited, Grubhub confirmed several key points. It has brought in a third-party cybersecurity firm and notified law enforcement. Beyond that, the company has stayed largely silent. That lack of detail has raised concern, especially given Grubhub’s recent security history. Just last month, the company was linked to scam emails sent from its own b.grubhub.com subdomain. Those messages promoted a cryptocurrency scam promising large returns on Bitcoin payments. Grubhub said it contained the incident and blocked further unauthorized emails. It did not clarify whether the two events are related.

Sources link the breach to ShinyHunters extortion

According to multiple sources cited by BleepingComputer, the ShinyHunters hacking group is behind the extortion attempt. The group has not publicly commented on the claims and declined to respond when contacted. Sources say the attackers are demanding a Bitcoin payment to prevent the release of stolen data. That data reportedly includes older Salesforce records from a February 2025 breach and newer Zendesk data taken during the most recent intrusion. Grubhub uses Zendesk to run its online customer support system. That platform handles order issues, account access and billing questions, making it a valuable target for attackers.

How stolen credentials may have enabled the attack

Investigators believe the breach may be tied to credentials stolen during earlier Salesloft Drift attacks. In August 2025, threat actors used stolen OAuth tokens from Salesloft’s Salesforce integration to access sensitive systems over a 10-day period. According to a report from Google Threat Intelligence Group, also known as Mandiant, attackers used that stolen data to launch follow-up attacks across multiple platforms. “GTIG observed UNC6395 targeting sensitive credentials such as AWS access keys, passwords and Snowflake-related access tokens,” Google reported. ShinyHunters previously claimed responsibility for that campaign, stating it stole roughly 1.5 billion records from Salesforce environments tied to hundreds of companies.

Why this breach still matters

Even if payment data and order history were not affected, support systems often contain personal details. Names, email addresses and account notes can be enough to fuel phishing attacks or identity scams. More importantly, this incident highlights how older breaches can continue to cause damage long after the initial attack. Stolen credentials that are never rotated remain a powerful entry point for threat actors.

Ways to stay safe after the Grubhub data breach

If you use Grubhub or any online delivery service, a few smart steps can reduce your risk after a breach.

1) Update your password and stop re-use

Start by changing your Grubhub password right away. Make sure you do not reuse that password anywhere else. Reused passwords give attackers an easy path into other accounts. A password manager can help here. It creates strong, unique logins and stores them securely so you do not have to remember them all.

Next, see if your email has been exposed in past breaches. Our No. 1 password manager pick includes a built-in breach scanner that checks whether your email address or passwords have appeared in known leaks. If you discover a match, immediately change any reused passwords and secure those accounts with new, unique credentials.

2) Turn on two-factor authentication

If two-factor authentication (2FA) is available, enable it. This adds a second step when you sign in, such as a code sent to your phone or app. Even if a hacker steals your password, two-factor authentication can stop them from getting in.

3) Watch closely for phishing attempts and use strong antivirus software

Be alert for emails or texts that mention orders, refunds or support issues. Attackers often use stolen support data to make messages feel urgent and real. Do not click links or open attachments unless you are certain they are legitimate. Strong antivirus software can also help block malicious links and downloads before they cause harm.

The best way to safeguard yourself from malicious links that install malware, potentially accessing your private information, is to have strong 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.

Get my picks for the best 2026 antivirus protection winners for your Windows, Mac, Android and iOS devices at Cyberguy.com.

4) Remove your data from people-search sites

Consider using a data removal service to reduce your online footprint. These services help remove your personal details from data broker sites that attackers often use to build profiles. Less exposed data means fewer tools for scammers to exploit.

While no service can guarantee the complete removal of your data from the internet, a data removal service is really a smart choice. They aren’t cheap, and neither is your privacy. These services do all the work for you by actively monitoring and systematically erasing your personal information from hundreds of websites. It’s what gives me peace of mind and has proven to be the most effective way to erase your personal data from the internet. By limiting the information available, you reduce the risk of scammers cross-referencing data from breaches with information they might find on the dark web, making it harder for them to target you.

Check out my top picks for data removal services and get a free scan to find out if your personal information is already out on the web by visiting Cyberguy.com.

5) Ignore crypto messages using trusted brands

Be skeptical of any cryptocurrency offers tied to familiar companies. Grubhub was previously linked to scam emails promoting crypto schemes, which shows how often attackers abuse trusted names. Legitimate companies do not promise fast returns or pressure you to act immediately.

6) Monitor your Grubhub account and email activity

Check your Grubhub account for anything that looks unfamiliar. Watch for unexpected password reset emails, order confirmations or support messages you did not request. Attackers often test stolen data quietly before making bigger moves.

7) Secure the email linked to your Grubhub account

Your email account is the key to password resets. Change that password and enable two-factor authentication if it is not already on. If attackers control your email, they can regain access even after you change other passwords.

8) Stay alert for delayed scams tied to the breach

Breach data is often reused weeks or months later. Phishing attempts may appear long after headlines fade. Treat any future messages claiming to reference Grubhub support, refunds or account issues with extra caution.

These steps will not undo a breach, but they can limit how attackers exploit stolen information and reduce your risk going forward.

Kurt’s key takeaways

Grubhub’s confirmation puts an official stamp on what sources have warned about for weeks. While the company says sensitive data was not affected, unanswered questions remain. As extortion-driven breaches rise, transparency and rapid credential rotation matter more than ever. What stands out most is how past compromises continue to create new risks. When access tokens live too long, attackers do not need to break in again. They simply walk back through an open door.

If companies stay quiet after breaches, how can customers know when it is time to protect themselves? Let us know by writing to us at Cyberguy.com.

TikTok is still down, here are all the latest updates

Starting early Sunday morning, TikTok’s now under new ownership US arm started breaking down just a couple of days after Oracle & Co took the reins. Its For You page algorithm is suddenly unreliable, while features like comments are failing to load or loading slowly, and publishing new videos seems nearly impossible for many people.

Rumors of censorship targeting anti-ICE protesting or attempting to block discussion of Jeffrey Epstein appear to be misguided (even the governor of California is resharing misinformation now), with problems blocking traffic to all kinds of videos and messages on the service through Monday night.

Malicious Google Chrome extensions hijack accounts

Malicious Google Chrome extensions hijack accounts

NEWYou can now listen to Fox News articles!

Cybersecurity researchers have uncovered a serious threat hiding inside Google Chrome.

Several browser extensions pretend to be helpful tools. In reality, they quietly take over user accounts. These extensions impersonate popular human resources and business platforms such as Workday, NetSuite and SAP SuccessFactors. Once installed, they can steal login data and block security controls designed to protect users.

Many people who installed them had no warning signs that anything was wrong.

The fake Chrome extensions to watch out for

Security researchers from Socket’s Threat Research Team identified five malicious Chrome extensions connected to this campaign. The add-ons were marketed as productivity or security tools, but were designed to hijack accounts.

The extensions include:

DataByCloud Access
Tool Access 11
DataByCloud 1
DataByCloud 2
Software Access

We reached out to Google, and a spokesperson told CyberGuy that the extensions are no longer available on the Chrome Web Store. However, some are still available on third-party software download sites, which continues to pose a risk. If you see any of these names installed in your browser, remove them immediately.

Why malicious Chrome extensions look legitimate

These malicious add-ons are designed to look legitimate. They use professional names, polished dashboards and business-focused descriptions. Some claim to offer faster access to workplace tools. Others say they restrict user actions to protect company accounts. Privacy policies often promise that no personal data is collected. For people juggling daily work tasks or managing business accounts, the pitch sounds helpful rather than suspicious.

What these extensions actually do

After installation, the extensions operate silently in the background. They steal session cookies, which are small pieces of data that tell websites you are already logged in. When attackers get these cookies, they can access accounts without a password. At the same time, some extensions block access to security pages. Users may be unable to change passwords, disable accounts or review login history. One extension even allows criminals to insert stolen login sessions into another browser. That lets them sign in instantly as the victim.

Why malicious Chrome extensions are so dangerous

This attack goes beyond stealing credentials. It removes the ability to respond. Security teams may detect unusual activity, but cannot fix it through normal controls. Password changes fail. Account settings disappear. Two-factor authentication tools become unreachable. As a result, attackers can maintain access for long periods without being stopped.

How to check for these extensions on your computer

If you use Google Chrome, review your extensions now. The process only takes a few minutes.

Open Google Chrome
Click the three-dot menu in the top right corner
Select Extensions, then choose Manage Extensions
Review every extension listed

Look for unfamiliar names, especially those claiming to offer access to HR platforms or business tools.

How to remove suspicious Chrome extensions

If you find one of these extensions, remove it immediately.

Open Manage Extensions in Chrome
Find the suspicious extension
Click Remove
Confirm when prompted

Restart your browser after removal to ensure the extension is fully disabled. If Chrome sync is enabled, repeat these steps on all synced devices before turning sync back on.

What to do after removing the extension

Removal is only the first step. Change passwords for any accounts accessed while the extension was installed. Use a different browser or device if possible.

A password manager can help you create strong, unique passwords for each account and store them securely. This reduces the risk of reused passwords being exploited again.

Check out the best expert-reviewed password managers of 2026 at Cyberguy.com.

Finally, review account activity for unfamiliar logins, locations or devices and be sure to follow the steps below to stay safe moving forward.

Ways to stay safe going forward

Simple habits can significantly reduce your risk.

1) Limit browser extensions

Only install extensions you truly need. The fewer extensions you use, the smaller your attack surface becomes.

2) Be cautious with add-ons

Avoid extensions that promise premium access or special tools for enterprise platforms. Legitimate companies rarely require browser add-ons for account access.

3) Check permissions carefully

Be wary of extensions that request access to cookies, browsing data or account management. These permissions can be abused to hijack sessions.

4) Review extensions regularly

Check your browser every few months and remove tools you no longer use or recognize.

5) Use strong antivirus software

Strong antivirus software can help detect malicious extensions, block suspicious behavior and alert you to browser-based threats before damage occurs.

6) Consider a data removal service

If your work or personal information has been exposed, a data removal service can help reduce your digital footprint by removing your details from data broker sites. This lowers the risk of follow-up scams or identity misuse.

7) Avoid third-party download sites

Do not reinstall extensions from third-party websites, even if they claim to offer the same features. These sites often host outdated or malicious versions.

Kurt’s key takeaways

Browser extensions can be useful, but this research shows how easily they can also be abused. These fake Chrome add-ons did not rely on flashy tricks or obvious warnings. They blended in, looked professional and quietly did their damage in the background. The good news is that you do not need to be a tech expert to protect yourself. Taking a few minutes to review your extensions, remove anything unfamiliar and lock down your accounts can make a real difference. Small habits, repeated regularly, go a long way in reducing risk. If there is one takeaway here, it is this: convenience should never come at the cost of security. A clean browser and strong account protections give you back control.

How many browser extensions do you have installed right now that you have never looked at twice? Let us know by writing to us at Cyberguy.com.
