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.

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.

A Kinect for kids is outselling Xbox to become the hot toy this holiday

Two years ago, the company sold about 5,000 units of the Playground. Last year, that number was roughly 150,000. This year, it’s on track for 600,000. Before its pivot, Nex did about $3 million of annual revenue and wasn’t profitable. This year, the company is projecting more than $150 million of sales and says it’s on pace to finally break even.

Fake Windows update pushes malware in new ClickFix attack

NEWYou can now listen to Fox News articles!

Cybercriminals keep getting better at blending into the software you use every day. 

Over the past few years, we’ve seen phishing pages that copy banking portals, fake browser alerts that claim your device is infected and “human verification” screens that push you to run commands you should never touch. The latest twist comes from the ongoing ClickFix campaign.

Instead of asking you to prove you are human, attackers now disguise themselves as a Windows update. It looks convincing enough that you might follow the instructions without thinking, which is exactly what they want.

NEW SCAM SENDS FAKE MICROSOFT 365 LOGIN PAGES

How the fake update works

Researchers noticed that ClickFix has upgraded its old trick. The campaign used to rely on human verification pages, but now you get a full-screen Windows update screen that looks almost identical to the real thing. Joe Security showed how the page displays fake progress bars, familiar update messages and a prompt that tells you to complete a critical security update.

If you are on Windows, the site tells you to open the Run box, copy something from your clipboard and paste it in. That “something” is a command that silently downloads a malware dropper. The final payload is usually an infostealer, which steals passwords, cookies and other data from your machine.

NEW EMAIL SCAM USES HIDDEN CHARACTERS TO SLIP PAST FILTERS

The moment you paste the command, the infection chain begins. First, a file called mshta.exe reaches out to a remote server and grabs a script. To avoid detection, these URLs often use hex encoding for parts of the address and rotate their paths. The script then runs obfuscated PowerShell code filled with junk instructions to throw researchers off. Once PowerShell does its work, it decrypts a hidden .NET assembly that functions as the loader.

Why is this attack so hard to detect?

The loader hides its next stage inside what looks like a regular PNG file. ClickFix uses custom steganography, which is a technique that hides secret data inside normal-looking content. In this case, the malware sits inside the image’s pixel data. The attackers tweak color values in certain pixels, especially in the red channel, to embed pieces of shellcode. When you view the image, everything appears normal.

The script knows exactly where the hidden data sits. It extracts the pixel values, decrypts them and rebuilds the malware directly in memory. That means nothing obvious is written to disk. Security tools that rely on file scanning miss it, since the shellcode never appears as a standalone file.

Once rebuilt, the shellcode is injected into a trusted Windows process like explorer.exe. The attack uses familiar in-memory techniques such as VirtualAllocEx, WriteProcessMemory and CreateRemoteThread. Recent ClickFix activity has delivered infostealers like LummaC2 and updated versions of Rhadamanthys. These tools are built to harvest credentials and send them back to the attacker with very little noise.

7 steps you can take to protect yourself from the ClickFix campaign

The best way to stay protected is to slow down for a moment and follow a few steps that cut off these attacks before they start.

1) Never run commands you didn’t ask for

If any site tells you to paste a command into Run, PowerShell or Terminal, treat it as an immediate warning sign. Real operating system updates never require you to run commands from a webpage. When you run that command, you hand full control to the attacker. If something feels off, close the page and don’t interact further.

2) Keep Windows updates inside Windows

Updates should only come from the Windows Settings app or through official system notifications. A browser tab or pop-up pretending to be a Windows update is always fake. If you see anything outside the normal update flow asking for your action, ignore it and check the real Windows Update page yourself.

3) Use a reputable antivirus

Choose a security suite that can detect both file-based and in-memory threats. Stealthy attacks like ClickFix avoid leaving obvious files for scanners to pick up. Tools with behavioral detection, sandboxing and script monitoring give you a much better chance of spotting unusual activity early.

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.

4) Use a password manager

Password managers create strong, unique passwords for every account you use. They also autofill only on legitimate websites, which helps you catch fake login pages. If a manager refuses to fill out your credentials, take a second look at the URL before entering anything manually.

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.

5) Use a personal data removal service

Many attacks start by targeting emails and personal details already exposed online. Data removal services help shrink your digital footprint by requesting takedowns from data broker sites that collect and sell your information. They can’t erase everything, but reducing your exposure means fewer attackers have easy access to your details.

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.

6) Check URLs before trusting anything

A convincing layout doesn’t mean it is legitimate. Always look at the domain name first. If it doesn’t match the official site or uses odd spelling or extra characters, close it. Attackers rely on the fact that people recognize a page’s design but ignore the address bar.

7) Close suspicious full-screen pages

Fake update pages often run in full-screen mode to hide the browser interface and make the page look like part of your computer. If a site suddenly goes full screen without your permission, exit with Esc or Alt+Tab. Once you’re out, scan your system and don’t return to that page.

Kurt’s key takeaway

ClickFix works because it leans on user interaction. Nothing happens unless you follow the instructions on the screen. That makes the fake Windows update page especially dangerous, because it taps into something most people trust. If you are used to Windows updates freezing your screen, you may not question a prompt that appears during the process. Cybercriminals know this. They copy trusted interfaces to lower your guard and then rely on you to run the final command. The technical tricks that follow are complex, but the starting point is simple. They need you to help them.

Parents call for New York governor to sign landmark AI safety bill

Parents call for New York governor to sign landmark AI safety bill

A group of more than 150 parents sent a letter on Friday to New York governor Kathy Hochul, urging her to sign the Responsible AI Safety and Education (RAISE) Act without changes. The RAISE Act is a buzzy bill that would require developers of large AI models — like Meta, OpenAI, Deepseek, and Google — to create safety plans and follow transparency rules about reporting safety incidents.

The bill passed in both the New York State Senate and the Assembly in June. But this week, Hochul reportedly proposed a near-total rewrite of the RAISE Act that would make it more favorable to tech companies, akin to some of the changes made to California’s SB 53 after large AI companies weighed in on it.

Many AI companies, unsurprisingly, are squarely against the legislation. The AI Alliance, which counts
Meta, IBM, Intel, Oracle, Snowflake, Uber, AMD, Databricks, and Hugging Face among its members, sent a letter in June to New York lawmakers detailing their “deep concern” about the RAISE Act, calling it “unworkable.” And Leading the Future, the pro-AI super PAC backed by Perplexity AI, Andreessen Horowitz (a16z), OpenAI president Greg Brockman, and Palantir co-founder Joe Lonsdale, has been targeting New York State Assemblymember Alex Bores, who co-sponsored the RAISE Act, with recent ads.

Two organizations, ParentsTogether Action and the Tech Oversight Project, put together Friday’s letter to Hochul, which states that some of the signees had “lost children to the harms of AI chatbots and social media.” The signatories called the RAISE Act as it stands now “minimalist guardrails” that should be made law.

They also highlighted that the bill, as passed by the New York State Legislature, “does not regulate all AI developers – only the very largest companies, the ones spending hundreds of millions of dollars a year.” They would be required to disclose large-scale safety incidents to the attorney general and publish safety plans. The developers would also be prohibited from releasing a frontier model “if doing so would create an unreasonable risk of critical harm,” which is defined as the death or serious injury of 100 people or more, or $1 billion or more in damages to rights in money or property stemming from the creation of a chemical, biological, radiological, or nuclear weapon; or an AI model that “acts with no meaningful human intervention” and “would, if committed by a human,” fall under certain crimes.

“Big Tech’s deep-pocketed opposition to these basic protections looks familiar because we have
seen this pattern of avoidance and evasion before,” the letter states. “Widespread damage to young people —
including to their mental health, emotional stability, and ability to function in school — has been
widely documented ever since the biggest technology companies decided to push algorithmic
social media platforms without transparency, oversight, or responsibility.”
