New Harry Potter-named malware strikes, revealing global espionage campaign

A new malware has been detected by security researchers that is suspected of conducting espionage. Hackers infect devices by impersonating government agencies, usually tax agencies such as the Internal Revenue Service (IRS). Once the malicious software is on a PC, it can gather intelligence (collecting personal data, passwords and more), download additional malicious software and upload data to the hacker’s server. It does all this while using Google Sheets to avoid suspicion and store data.

It all starts with a fake email

The hackers behind the malware, called “Voldemort,” have cleverly designed it to avoid getting caught. Just like the name Voldemort spelled trouble in J.K. Rowling’s Harry Potter series, it’s causing issues in the cybersecurity world, too.

The cyberattack kicks off when you receive an email that looks like it’s from a government tax agency. According to Proofpoint, the hackers behind this campaign have been impersonating tax agencies in various countries, including the U.S. (IRS), the U.K. (HM Revenue & Customs), France (Direction Générale des Finances Publiques), Germany (Bundeszentralamt für Steuern), Italy (Agenzia delle Entrate) and, as of Aug. 19, India (Income Tax Department) and Japan (National Tax Agency). Each email lure was customized and written in the language of the tax authority being impersonated.

Proofpoint analysts found that the hackers tailored their phishing emails to match the target’s country of residence based on publicly available information rather than the organization’s location or the language suggested by the email address. For example, some targets in a European organization received emails impersonating the IRS because they were linked to the U.S. in public records. In some cases, the hackers mixed up the country of residence when the target shared a name with a more prominent individual.

The email also tries to mimic the email of the government agency. For example, the U.S. folks were sent fake emails using “no_reply_irs[.]gov@amecaindustrial[.]com.”

The attack cleverly unfolds on your device

In the fake email, hackers impersonating the government warn you about changes in the tax rates and tax systems and ask you to click a link to read a detailed guide. Clicking on the link brings you to a landing page, which uses Google AMP Cache URLs to redirect you to a page with a “Click to view document” button.

After you click the button, the hackers check if you’re using a Windows device. If you are, you’ll be redirected to another page. When you interact with that page, it triggers a download that looks like a PDF file in your PC’s download folder, but it’s actually an LNK or ZIP file hosted on an external server.

When you open the file, it runs a Python script from another server without actually downloading the script to your computer. This script collects system information to profile you, while a fake PDF opens to hide the malicious activity.

Voldemort uses Google Sheets to store data

Once the malware has successfully infected your Windows device, it can:

Ping: Check if it’s still connected to its control server
Dir: Get a list of files and folders on your system
Download: Send files from your system to the control server
Upload: Put files from the control server onto your system
Exec: Run specific commands or programs on your system
Copy: Copy files or folders on your system
Move: Move files or folders around on your system
Sleep: Pause its activity for a set time
Exit: Stop running on your system

The malware uses Google Sheets as its command center, where it gets new instructions and stores stolen data. Each infected device sends its data to specific cells in the Google Sheet, marked by unique IDs to keep everything organized.

Voldemort interacts with Google Sheets through Google’s API, using an embedded client ID, secret and refresh token stored in its encrypted settings. This method gives the malware a reliable way to communicate without raising suspicion since Google Sheets is widely used in businesses, making it hard for security tools to block it.

HOW TO RECOGNIZE AND AVOID BEING A VICTIM OF VACATION RENTAL SCAMS

4 ways to protect yourself from malware attacks

Hackers are releasing increasingly sophisticated malware, but that doesn’t mean you’re defenseless. Below are some tips to help protect yourself from such attacks.

1) Read sensitive emails carefully: The best way to spot fake emails that deliver malware is to check them carefully. While hackers may be tech-savvy, their language skills often aren’t perfect. For example, in the screenshots above, you can see typos like “Taxplayers” instead of “Taxpayers.” Government agencies don’t usually make these kinds of mistakes.

2) Check email domain: Verify that the email domain matches the organization it claims to represent. For example, an email from the IRS should come from an address ending in “@irs.gov.” Be cautious of slight misspellings or variations in the domain.

3) Invest in data removal services: Hackers target you based on your publicly available information. That could be anything from your leaked info through a data breach to the information you provided to an e-commerce shop. Check out my top picks for data removal services here.

4) Have strong antivirus software: If you have strong antivirus software installed on your device, it can protect you when you receive these types of scam emails or accidentally open the attachment or click a link. 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 and iOS devices.

Kurt’s key takeaway

While researchers can’t say for sure, many of the techniques used by the malware are similar to those employed by hackers suspected of espionage. Even if this assessment turns out to be incorrect, the scale and sophistication of the attack are concerning. Anyone without technical knowledge could easily fall victim and lose personal data and money. This attack specifically targets Windows users, which also raises questions about Microsoft’s security framework.

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:

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.

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.”
