🔧Technical Breakdown
The 'YouTube Ghost Network' operated by embedding malicious content in videos that masqueraded as cracked software and game cheats. The attackers used legitimate YouTube accounts to enhance credibility and attract viewers. Once users clicked on the links provided in video descriptions, they were directed to download malware disguised as software. The malware, primarily infostealers, was designed to harvest sensitive information, including passwords and personal data. The operational method relied heavily on social engineering, convincing users that the downloaded content was safe.
