Selling on the internet? Beware of sneaky tactics scammers use to trick you

Selling stuff online can be tempting. You don’t have to go out and hunt for buyers. Instead, you can just post an ad on platforms like eBay or Facebook Marketplace and wait for people to reach out to you. But along with the ease of online selling comes the risk of getting scammed.

One of the popular scams to watch out for is the Google Voice verification scam. This scam preys on unsuspecting sellers by exploiting their trust and the convenience of online communication. Scammers pose as potential buyers and use seemingly innocent requests to gain access to your personal information. Their ultimate goal is to hijack your phone number and use it for fraudulent activities.

Here’s how it works: A scammer will send you a text with a Google Voice verification code and ask you to share it with them. If you do, they’ll use that code to create a Google Voice number linked to your phone number. Once they’ve got that, they can use your number for all sorts of shady stuff, like identity theft.

Recently, I received an email from Allen C., a resident of Island Park, New York, explaining how he almost fell prey to the Google Voice scam. Below, I share Allen’s story, discuss the impact of such scams and provide tips on how you can protect yourself.

How scammers prey on innocent online sellers

Allen told me he was trying to sell an item on eBay when he received a message from someone saying they were interested in buying the item. The person asked for his number, saying she was at work and her husband would contact him. Allen gave his contact number, but then she asked him to share a code.

“At first I thought it was legit, but then she told me she needs to confirm I was real, so she sends me this code through Google Voice, it gave me a 6 digit code which I was supposed to send back,” Allen told me.

“After thinking about it, I was trying to figure out why she needed to know if I was real, when we didn’t even discuss the item I was selling! I did some checking and she started spelling words wrong, she said she didn’t get the return code, I know she did, she begged me to let her send another one. My research confirmed it was probably a scam.”

Allen realized it was a scam just in time, refused to give the scammer his cell number and deleted the message.

What happens when you give the code to scammers

Once you provide scammers with your Google Voice verification code, they can create a Google Voice number that is linked to your phone number. This gives them significant control over a virtual phone number associated with your real one, which poses serious risks.

One of the main dangers is that scammers can intercept verification codes sent by banks and financial institutions. When these institutions send a verification code to authorize a transaction, it may be redirected to the scammer’s Google Voice number instead of your phone. This allows the scammer to authorize fraudulent transactions, reset passwords and gain access to your financial accounts, effectively bypassing your security measures.

Additionally, by controlling a number linked to your identity, scammers can engage in identity theft. They may open a new credit card or loan account in your name, impersonate you to access other services that rely on phone verification and exploit your phone number as a recovery option for various accounts.

Furthermore, scammers can use the Google Voice number to conduct additional scams while appearing to have a legitimate U.S.-based number. This tactic helps them hide their true identity and makes it more challenging for authorities to trace their actions.

Ultimately, by gaining control of a number associated with your identity, scammers acquire a powerful tool that undermines common security measures that rely on phone verification. This can lead to financial losses, damage to your credit score and a complicated process of reclaiming your identity and securing your accounts.

How to reclaim your Google Voice number?

If you’ve given a scammer the verification, your linked number has been claimed, and someone else is using that number with another Voice account. If you still own the linked number, you can reclaim it by following these steps:

  • On your computer, go to voice.google.com.
  • Click Settings in the upper right corner.
  • Under Linked numbers, click New linked number, then enter the phone number to link
  • To verify your number, Google will provide a six-digit code. For a mobile number, click Send Code to review the code in a text message. If it’s a landline, click verify by phone link and then Call.
  • Enter the code and click Verify, then Claim

4 other ways to protect yourself from such scams

Scammers don’t only use Google Voice to scam you. They have plenty of other tactics, such as making you install malware to steal your data and passwords. Below are some tips to avoid getting scammed.

1) Check the email address: When you’re trying to sell something online, scammers might reach out to you via email and try to get you to click on malicious links. These links may look harmless, but they can give scammers access to your device and important data. Do not click on any links or attachments in the email and do not reply to it. Remember, you don’t need to click any links to sell an item online.

The best way to safeguard yourself from malicious links that install malware and potentially access 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 2024 antivirus protection winners for your Windows, Mac, Android and iOS devices.

2) Avoid the sense of urgency: Many online selling scams create a sense of urgency or panic to trick you. Scammers might tell you that there’s a problem with your account, claim that you owe money, suggest that there’s an issue with your listing or even offer you a prize.

They may pressure you to act quickly, asking you to send money, provide personal information or buy gift cards. Don’t let them rush or pressure you. Take a moment to think carefully before you respond. If you’re unsure, consult someone you trust, such as a friend, family member or financial adviser. Remember, legitimate buyers or platforms will never ask you to pay with gift cards, wire transfers or cryptocurrency.

3) Verify buyer or seller’s identity: If you receive a message or call from someone claiming to be a buyer, a platform representative or an organization related to your online sale, don’t trust them blindly. Scammers may use fake names, phone numbers or email addresses to deceive you. They might also have some information about you, such as your name or listing details, which doesn’t mean they are legitimate. This information could be obtained from public sources or previous scams.

Do not provide any additional personal information, such as your bank details, password or Social Security number. Avoid agreeing to any unusual requests, like sending money, buying gift cards or sharing codes. Instead, verify their identity by contacting the organization or platform directly using a known, official contact method. You can also check the organization’s website for any alerts or warnings about scams.

4) Invest in personal data removal services: Removing yourself from the internet is an important step in protecting your personal information from scammers and cybercriminals. Even if you’re not selling anything online, removing your personal information from the web is crucial. This prevents scammers from obtaining your data to make fraudulent calls or create convincing scams. By limiting your online presence, you reduce the chances of scammers finding and exploiting your personal details. Additionally, deleting yourself from the internet ensures that scammers cannot access your personal information to call you or make you believe they have some of your credentials, making their scams seem legitimate.

While no service promises to remove all your data from the internet, having a removal service is great if you want to constantly monitor and automate the process of removing your information from hundreds of sites continuously over a longer period of time. Check out my top picks for data removal services here.

Kurt’s key takeaway

Selling items online can be easy, but it comes with risks, such as the Google Voice scam. If someone asks you for a verification code or personal details during a sale, be extra cautious. Always verify their legitimacy and use official channels for communication. Only use trusted platforms to sell anything online and take steps to protect yourself from identity theft, which can impact your finances for years.

Here’s your first look at Kratos in Amazon’s God of War show

Here’s your first look at Kratos in Amazon’s God of War show

Amazon has slowly been teasing out casting details for its live-action adaptation of God of War, and now we have our first look at the show. It’s a single image but a notable one showing protagonist Kratos and his son Atreus. The characters are played by Ryan Hurst and Callum Vinson, respectively, and they look relatively close to their video game counterparts.

There aren’t a lot of other details about the show just yet, but this is Amazon’s official description:

The God of War series storyline follows father and son Kratos and Atreus as they embark on a journey to spread the ashes of their wife and mother, Faye. Through their adventures, Kratos tries to teach his son to be a better god, while Atreus tries to teach his father how to be a better human.

That sounds a lot like the recent soft reboot of the franchise, which started with 2018’s God of War and continued through Ragnarök in 2022. For the Amazon series, Ronald D. Moore, best-known for his work on For All Mankind and Battlestar Galactica, will serve as showrunner. The rest of the cast includes: Mandy Patinkin (Odin), Ed Skrein (Baldur), Max Parker (Heimdall), Ólafur Darri Ólafsson (Thor), Teresa Palmer (Sif), Alastair Duncan (Mimir), Jeff Gulka (Sindri), and Danny Woodburn (Brok).

While production is underway on the God of War series, there’s no word on when it might start streaming.

300,000 Chrome users hit by fake AI extensions

NEWYou can now listen to Fox News articles!

Your web browser may feel like a safe place, especially when you install helpful tools that promise to make your life easier. But security researchers have uncovered a dangerous campaign in which more than 300,000 people installed Chrome extensions pretending to be artificial intelligence (AI) assistants. Instead of helping, these fake tools secretly collect sensitive information like your emails, passwords and browsing activity.

They used familiar names like ChatGPT, Gemini and AI Assistant. If you use Chrome and have installed any AI-related extension, your personal information may already be exposed. Even worse, some of these malicious extensions are still available today, putting more people at risk without their knowing.

What you need to know about fake AI extensions

Security researchers at browser security company LayerX discovered a large campaign involving 30 malicious Chrome extensions disguised as AI-powered assistants (via BleepingComputer). Together, these extensions were installed more than 300,000 times by unsuspecting users.

Some of the most popular extensions included names like AI Sidebar with 70,000 users, AI Assistant with 60,000 users, ChatGPT Translate with 30,000 users, and Google Gemini with 10,000 users. Another extension called Gemini AI Sidebar had 80,000 users before it was removed.

These extensions were distributed through the official Chrome Web Store, which made them appear legitimate and trustworthy. Even more concerning, researchers found that many of these extensions were connected to the same malicious server, showing they were part of a coordinated effort.

While some extensions have since been removed, others remain available. This means new users could still unknowingly install them and expose their personal data. Here’s the list of the affected extensions:

  • AI Assistant
  • Llama
  • Gemini AI Sidebar
  • AI Sidebar
  • ChatGPT Sidebar
  • Grok
  • Asking ChatGPT
  • ChatGBT
  • Chat Bot GPT
  • Grok Chatbot
  • Chat With Gemini

How the fake AI Chrome extension attack works

These fake extensions pretend to offer helpful AI features, such as translating text, summarizing emails, or acting as an AI assistant. But behind the scenes, they quietly monitor what you are doing online.

Once installed, the extension gains permission to view and interact with the websites you visit. This allows it to read the contents of web pages, including login screens where you enter your username and password.

In some cases, the extensions specifically targeted Gmail. They could read your email messages directly from your browser, including emails you received and even drafts you were still writing. This means attackers could access private conversations, financial information and sensitive personal details.

The extensions then sent this information to servers controlled by the attackers. Because they loaded content remotely, the attackers could change their behavior at any time without needing to update the extension.

Some versions could also activate voice features through your browser. This could potentially capture spoken conversations near your device and send transcripts back to the attackers.

If you installed one of these extensions, attackers may already have access to extremely sensitive information. This includes your email content, login credentials, browsing habits and possibly even voice recordings.

We reached out to Google for comment, and a spokesperson told CyberGuy that the company “can confirm that the extensions from this report have all been removed from the Google Web Store.”

7 ways you can protect yourself from malicious Chrome extensions

If you have ever installed an AI-related Chrome extension, taking a few simple precautions now can help protect your accounts and prevent further damage.

Advertisement

1) Remove any suspicious or unused browser extensions

On a Windows PC or Mac, open Chrome and type chrome://extensions into the address bar. Review every extension listed. If you see anything unfamiliar, especially AI assistants you don’t remember installing, click “Remove” immediately. Malicious extensions depend on going unnoticed. Removing them stops further data collection and cuts off the attacker’s access to your information.

2) Change your passwords

If you installed any suspicious extension, assume your passwords may be compromised. Start by changing your email password first, since email controls access to most other accounts. Then update passwords for banking, shopping and social media accounts. This prevents attackers from using stolen credentials to break into your accounts.

3) Use a password manager to create and protect strong passwords

A password manager generates unique, complex passwords for each account and stores them securely. This prevents attackers from accessing multiple accounts if one password is stolen. Password managers also alert you if your login credentials appear in known data breaches, helping you respond quickly and protect your identity. Check out the best expert-reviewed password managers of 2026 at Cyberguy.com.

4) Install strong antivirus software and keep it active

Good antivirus software can detect malicious browser extensions, spyware, and other hidden threats. It scans your system for suspicious activity and blocks harmful programs before they can steal your information. This adds an important layer of protection that works continuously in the background to keep your device safe. Get my picks for the best 2026 antivirus protection winners for your Windows, Mac, Android & iOS devices at Cyberguy.com.

5) Use an identity theft protection service

Identity theft protection services monitor your personal data, including email addresses, financial accounts, and Social Security numbers, for signs of misuse. If criminals try to open accounts or commit fraud using your information, you receive alerts quickly. Early detection allows you to act fast and limit financial and personal damage. See my tips and best picks on how to protect yourself from identity theft at Cyberguy.com.

6) Keep your browser and computer fully updated

Software updates fix security vulnerabilities that attackers exploit. Enable automatic updates for Chrome and your operating system so you always have the latest protections. These updates strengthen your defenses against malicious extensions and prevent attackers from taking advantage of known weaknesses.

7) Use a personal data removal service

Personal data removal services scan data broker websites that collect and sell your personal information. They help remove your data from these sites, reducing what attackers can find and use against you. Less exposed information means fewer opportunities for criminals to target you with scams, identity theft or phishing attacks.

Kurt’s key takeaway

Even tools designed to make your life easier can become tools for cybercriminals. Malicious extensions often hide behind trusted names and convincing features, making them difficult to spot. You can significantly reduce your risk by reviewing your browser extensions regularly, removing anything suspicious and using protective tools like password managers and strong antivirus software.

Anthropic refuses Pentagon’s new terms, standing firm on lethal autonomous weapons and mass surveillance

Anthropic refuses Pentagon’s new terms, standing firm on lethal autonomous weapons and mass surveillance

Less than 24 hours before the deadline in an ultimatum issued by the Pentagon, Anthropic has refused the Department of Defense’s demands for unrestricted access to its AI.

It’s the culmination of a dramatic exchange of public statements, social media posts, and behind-the-scenes negotiations, coming down to Defense Secretary Pete Hegseth’s desire to renegotiate all AI labs’ current contracts with the military. But Anthropic, so far, has refused to back down from its two current red lines: no mass surveillance of Americans, and no lethal autonomous weapons (or weapons with license to kill targets with no human oversight whatsoever). OpenAI and xAI had reportedly already agreed to the new terms, while Anthropic’s refusal had led to CEO Dario Amodei being summoned to the White House this week for a meeting with Hegseth himself, in which the Secretary reportedly issued an ultimatum to the CEO to back down by the end of business day on Friday or else.

In a statement late Thursday, Amodei wrote, “I believe deeply in the existential importance of using AI to defend the United States and other democracies, and to defeat our autocratic adversaries. Anthropic has therefore worked proactively to deploy our models to the Department of War and the intelligence community.”

He added that the company has “never raised objections to particular military operations nor attempted to limit use of our technology in an ad hoc manner” but that in a “narrow set of cases, we believe AI can undermine, rather than defend, democratic values” — going on to specifically mention mass domestic surveillance and fully autonomous weapons. (Amodei mentioned that “partial autonomous weapons … are vital to the defense of democracy” and that fully autonomous weapons may eventually “prove critical for our national defense,” but that “today, frontier AI systems are simply not reliable enough to power fully autonomous weapons.” He did not rule out Anthropic acquiescing to the military’s use of fully autonomous weapons in the future but mentioned that they were not ready now.)

The Pentagon had already reportedly asked major defense contractors to assess their dependence on Anthropic’s Claude, which could be seen as the first step to designating the company a “supply chain risk” – a public threat that the Pentagon had made recently (and a classification usually reserved for threats to national security). The Pentagon was also reportedly considering invoking the Defense Production Act to make Anthropic comply.

Amodei wrote in his statement that the Pentagon’s “threats do not change our position: we cannot in good conscience accede to their request.” He also wrote that “should the Department choose to offboard Anthropic, we will work to enable a smooth transition to another provider, avoiding any disruption to ongoing military planning, operations, or other critical missions. Our models will be available on the expansive terms we have proposed for as long as required.”
