YouTube remains the go-to platform for entertainment, tutorials, and educational content, attracting billions of viewers daily. However, recent investigations reveal a concerning underground operation exploiting the platform’s reach to spread malicious software. According to cybersecurity firm Check Point Research, over 3,000 videos are used to distribute malware disguised as free software, game cheats, and cracked applications, creating a significant threat to unsuspecting users.

The Hidden Malware Network on YouTube

Since 2021, a sophisticated cybercriminal network dubbed the Ghost Network has been leveraging YouTube’s ecosystem to infect users’ devices. The network’s activity surged threefold in 2025, highlighting its rapid growth and resilience. It primarily targets individuals searching for “game hacks,” “software cracks,” and piracy tools, exploiting their curiosity for free or modified programs.

The Role of Social Engineering and Fake Engagement

Malicious videos often appear legitimate, featuring numerous likes, positive comments, and active community posts from compromised or fake accounts. This artificially inflated engagement fosters a false sense of trust and credibility among viewers, making them more likely to click on malicious links. Despite YouTube removing some channels or videos, the network’s modular design ensures ongoing operation through quick account replacements and coordinated social manipulation tactics.

The Mechanics of Infection

Clicking on links in these videos redirects users to file-sharing sites, such as MediaFire, Dropbox, or Google Sites, where the dangerous files are hosted. These archives are usually password-protected, complicating antivirus scans, and victims are often instructed to disable their Windows Defender or other security software before installing. Once executed, the malware—mainly info-stealers like RedLine, Lumma Stealer, Rhadamanthys, and StealC—begins extracting sensitive data, including passwords and browser histories, transmitting it to attacker-controlled servers.

Targeted Campaigns and Notorious Channels

Two prominent campaigns exemplify the threat. One involved the Rhadamanthys infostealer distributed via a compromised channel with nearly 10,000 subscribers, @Sound_Writer. Attackers uploaded fake cryptocurrency videos, directing viewers to phishing pages that prompted disabling security tools and executing malicious files. Another campaign used a larger channel, @Afonseio1, with over 129,000 subscribers, to promote cracked versions of Adobe Photoshop, Premiere Pro, and FL Studio. These videos garnered hundreds of thousands of views, with malicious payloads hidden within password-protected archives.

<h2 Risks for Users and How to Protect Yourself

Even viewing or clicking links in these videos without installing software can compromise your device through malicious scripts or credential theft prompts. The success of the Ghost Network hinges on exploiting users’ trust and curiosity. To stay safe, cybersecurity experts recommend several best practices:

• Always download software directly from official sources or reputable app stores.
• Use a trusted antivirus program with real-time protection and keep it up to date.
• Never disable your security software or ignore prompts to do so.
• Inspect links carefully—hover over URLs to verify their destination before clicking.
• Enable two-factor authentication (2FA) on important accounts to add an extra security layer.
• Regularly check if your email or passwords have been involved in data breaches using trusted breach scanners.
• Keep your operating system and applications updated to fix security vulnerabilities.

The Need for Vigilance in a Digital Threat Landscape

Cybercriminals are continuously evolving, using social engineering, password protection, and dynamic control servers to evade detection. The exploitation of YouTube’s engagement features underscores the importance of cautious online behavior. Staying informed and applying robust security measures are essential defenses against these covert malware campaigns.
