YouTube is arguably the most popular and most visited platform for entertainment, education and tutorials. There’s a video for everything on YouTube, whether you want to learn how to cook, ride a bike or need help with work or school. But recent research by Check Point reveals a darker side: a sprawling malware distribution network quietly operating within the platform. Hackers are using compromised accounts, fake engagement and clever social engineering to spread information-stealing malware disguised in more than 3,000 software cracks and game hack videos.

Most victims begin by searching for free or cracked software, cheat tools or game hacks, which is the root of the infection chain. This curiosity for “free” software opens the door to the Ghost Network’s traps.

All about YouTube’s ghost network

According to Check Point Research, the YouTube Ghost Network has been active since 2021, with activity surging threefold in 2025. It’s built around a simple but effective formula, which blends social manipulation with technical stealth. The network’s primary targets are people searching for “Game Hacks/Cheats” and “Software Cracks/Piracy.”

Researchers discovered that these videos often feature positive comments, likes and community posts from compromised or fake accounts. This coordinated engagement gives potential victims a false sense of safety.

The fake social proof and fabricated likes, comments and subscriber activity play a key psychological role. They trick viewers into believing the content is legitimate and widely trusted, allowing the operation to persist even when YouTube removes individual videos or channels. The network’s modular structure and constant replacement of banned accounts make takedowns only temporarily effective.

Once a user clicks the provided links, they’re usually taken to file-sharing services or phishing sites hosted on Google Sites, MediaFire, Dropbox or similar platforms. The linked files are often password-protected archives, making them harder for antivirus tools to scan. Victims are then asked to disable Windows Defender before installation, effectively disarming their own protection before running the malware.

Check Point found that the majority of these attacks deliver information-stealing malware such as Lumma Stealer, Rhadamanthys, StealC and RedLine. These programs harvest passwords, browser data and other sensitive information, sending it back to the attacker’s command and control servers.

What makes the network particularly resilient is its role-based structure. Each compromised YouTube account serves a function; some upload malicious videos, others post download links and a third group boosts credibility by commenting and liking content. When an account gets banned, it’s quickly replaced, allowing the operation to continue largely uninterrupted.

Inside the malicious campaigns

Two major campaigns stood out in Check Point’s investigation. The first involved the Rhadamanthys infostealer, spread through a compromised YouTube channel named @Sound_Writer, which had nearly 10,000 subscribers.

The attackers uploaded fake cryptocurrency-related videos and used phishing pages on Google Sites to distribute malicious archives. These pages instructed viewers to “turn off Windows Defender temporarily,” assuring them it was a false alert. The archives contained executable files that quietly installed the Rhadamanthys malware, which connected to multiple control servers to exfiltrate stolen data.

The second campaign, involving HijackLoader and Rhadamanthys, leveraged a much larger channel, @Afonesio1, with around 129,000 subscribers. Here, attackers uploaded videos offering cracked versions of Adobe Photoshop, Premiere Pro, and FL Studio.

One of these videos gained over 291,000 views and dozens of glowing comments claiming the software worked perfectly. The malware was hidden inside a password-protected archive linked through a community post. The installer used HijackLoader to drop the Rhadamanthys payload, which then connected to rotating control servers every few days to avoid detection.

Even if you never complete the installation, you can still be at risk. Simply visiting the phishing or file-hosting sites may expose you to malicious scripts or credential theft prompts disguised as “verification” steps. Clicking the wrong link can compromise login data before any software is even installed.

7 steps you can take to stay safe from YouTube’s ghost network

The Ghost Network succeeds by exploiting curiosity and trust. It disguises malware as “free software” or “game hacks,” relying on users to click before thinking. Protecting yourself means adopting habits that make it harder for attackers to fool you. Here are seven steps to stay safe:

1) Avoid cracked software and cheat downloads

Most infections start with people trying to download pirated or modified programs. These files are often hosted on unregulated file-sharing websites where anyone can upload malicious content. Even if a YouTube video looks polished or filled with positive comments, that doesn’t mean it’s safe. Official software developers and gaming studios never distribute downloads through YouTube links or third-party sites.

Besides being dangerous, downloading cracked software also poses legal risks. Piracy violates copyright law and can lead to serious consequences, while giving cybercriminals a perfect delivery channel for malware.

2) Use a strong antivirus

Make sure you have a trusted antivirus solution installed and always running. Real-time protection can detect suspicious downloads and block harmful files before they do any damage. Schedule regular system scans and keep your antivirus updated so it can recognize the latest threats.

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.

WHAT REALLY HAPPENS ON THE DARK WEB, AND HOW TO STAY SAFE

3) Never disable your antivirus or Windows Defender

If a tutorial or installer tells you to disable your security software, that’s a red flag. Malware creators use this trick to bypass detection. There’s no legitimate reason to turn off protection, even temporarily. The moment a file asks you to do so, delete it immediately.

4) Be cautious with YouTube links and download sources

Always inspect links before clicking. Hover over them to check the destination and avoid shortened or redirected URLs that hide their true target. Downloads hosted on unfamiliar domains or file-sharing sites should be treated as unsafe. If you need software, get it directly from the official website or trusted open-source communities.

5) Use a password manager and enable two-factor authentication (2FA)

Turning on 2FA for important accounts adds another layer of protection, ensuring that even if someone gets your password, they can’t access your account. Malware often aims to steal saved passwords and browser data. Storing credentials in a password manager keeps them encrypted and separate from your browser, making them harder to steal. Consider using a password manager, which securely stores and generates complex passwords, reducing the risk of password reuse. 

Next, see if your email has been exposed in past breaches. Our #1 password manager (see CyberGuy.com) 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.

6) Keep your operating system and apps updated

Software updates don’t just bring new features, but they also fix security flaws that malware can exploit. Enable automatic updates for your system, browser, and commonly used applications. Staying up to date is one of the simplest ways to prevent infections.

7) Use a trusted data removal service

Even after securing your system, your personal information might already be circulating online from past breaches. A reliable data removal service can continuously scan and request deletion of your data from people-search and broker sites, making it harder for cybercriminals to exploit your exposed information.

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.

Kurt’s key takeaway

Cybercriminals have evolved beyond traditional phishing and email scams. By exploiting a platform built on trust and engagement, they have created a scalable, self-sustaining system for malware distribution. Frequent file updates, password-protected payloads, and shifting control servers make these campaigns difficult for both YouTube and security vendors to detect and shut down.

A massive online leak has exposed more than 183 million stolen email passwords gathered from years of malware infections, phishing campaigns and older data breaches. Cybersecurity experts say it is one of the largest compilations of stolen credentials ever discovered.

Security researcher Troy Hunt, who runs the website Have I Been Pwned, found the 3.5-terabyte dataset online. The credentials came from infostealer malware and credential stuffing lists. This malware secretly collects usernames, passwords and website logins from infected devices.

Researchers say the data contains both old and newly discovered credentials. Hunt confirmed that 91% of the data had appeared in previous breaches, but about 16.4 million email addresses were completely new to any known dataset.

The real risk behind the password leak

The leak puts millions of users at risk. Hackers often collect stolen logins from multiple sources and combine them into large databases that circulate on dark web forums, Telegram channels and Discord servers.

If you have reused passwords across multiple sites, attackers can use this data to break into your accounts through credential stuffing. This method tests stolen username and password pairs on many different platforms.

The risk remains real for anyone using old or repeated credentials. One compromised password can unlock social media, banking and cloud accounts.

Google responds to the reports

Google confirmed there was no Gmail data breach. In a post on X, the company stated “reports of a Gmail security breach impacting millions of users are false. Gmail’s defenses are strong, and users remain protected.”

Google clarified that the leak came from infostealer databases that compile years of stolen credentials from across the web. These databases are often mistaken for new breaches when, in fact, they represent ongoing theft activity. Troy Hunt also confirmed the dataset originated from Synthient’s collection of infostealer logs, not from a single platform or recent attack. While no new breach occurred, experts warn that leaked credentials remain dangerous because cybercriminals reuse them for future attacks.

How to check if you were exposed

To see if your email was affected, visit Have I Been Pwned. It is the first and official source for this newly added dataset. Enter your email address to find out if your information appears in the Synthient leak.

Many password managers also include built-in breach scanners that use the same data sources. However, they may not yet include this new collection until their databases update.

If your address shows up, treat it as compromised. Change your passwords immediately and turn on stronger security features to protect your accounts.

9 steps to protect yourself now

Protecting your online life starts with consistent action. Each step below adds another layer of defense against hackers, malware and credential theft.

1) Change your passwords immediately

Start with your most important accounts, such as email and banking. Use strong, unique passwords with letters, numbers and symbols. Avoid predictable choices like names or birthdays. 

Never reuse passwords. One stolen password can unlock multiple accounts. Each login should be unique to protect your data.

A password manager makes this simple. It stores complex passwords securely and helps you create new ones. Many managers also scan for breaches to see if your current passwords have been exposed.

Next, check whether your email has been caught in a recent credential leak. Our No. 1 password manager pick includes a built-in Breach Scanner that searches trusted databases, including the newly added Synthient data from Have I Been Pwned. It helps you find out if your email or passwords have appeared in any known leaks. If you see a match, change any reused passwords right away and secure those accounts with strong, unique credentials.

2) Enable two-factor authentication (2FA)

Turn on 2FA wherever possible. It adds a powerful second layer of defense that blocks intruders even if they have your password. You will receive a code by text, app or security key. That code ensures only you can log in to your accounts.

3) Use an identity theft service for continuous monitoring

Identity Theft companies can monitor personal information like your Social Security number (SSN), phone number and email address, and alert you if it is being sold on the dark web or being used to open an account. They can also assist you in freezing your bank and credit card accounts to prevent further unauthorized use by criminals. It’s a smart way to stay one step ahead of hackers.

4) Protect your devices with strong antivirus software 

Infostealer malware hides inside fake downloads and phishing attachments. A strong antivirus software scans your devices to stop threats before they spread. Keep your antivirus updated and run frequent scans. Even one unprotected device can put your whole digital life at risk.

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.

5) Avoid saving logins in your web browser

Browsers are convenient but risky. Infostealer malware often targets saved passwords in your web browser. 

6) Keep software updated

Updates fix security flaws that hackers exploit. Turn on automatic updates for your operating system, antivirus and apps. Staying current keeps threats out. 

7) Download only from trusted sources

Avoid unknown websites that offer free downloads. Fake apps and files often contain hidden malware. Use official app stores or verified company websites. 

8) Review your account activity often

Check your accounts regularly for unusual logins or device connections. Many platforms show a login history. If something looks off, change your password and enable 2FA immediately.

9) Consider a personal data removal service

The massive leak of 183 million credentials shows just how far your personal information can spread and how easily it can resurface years later in aggregated hacker databases. Even if your passwords were part of an old breach, data like your name, email, phone number or address may still be available through data broker sites. Personal data removal services can help reduce your exposure by scrubbing this information from hundreds of these sites.

While no service can guarantee total removal, they drastically reduce your digital footprint, making it harder for scammers to cross-reference leaked credentials with public data to impersonate or target you. These services monitor and automatically remove your personal info over time, which gives me peace of mind in today’s threat landscape.
