Summary

Hide ▲

APT24 is running a three-year espionage campaign with BadAudio that has expanded into multiple delivery methods, increasing the operation's reach and stealth. Since 2022, the group has used spearphishing, supply-chain compromise, and watering hole attacks to deliver the malware. The campaign compromised more than 20 legitimate public websites and later abused a Taiwanese marketing firm's JavaScript supply chain to reach more than 1,000 domains. The targeting focused exclusively on Windows systems, and a separate spearphishing wave began in August 2024 using animal-rescue lures and cloud services.

    APT24 BadAudio espionage campaign disclosed

    Initial Disclosure

    Google Threat Intelligence Group described APT24 as running a three-year espionage campaign with previously undocumented BadAudio malware against Windows systems, using spearphishing, supply-chain compromise, and watering hole attacks. The campaign compromised more than 20 legitimate public websites from November 2022 until at least September 2025, repeatedly compromised a digital marketing company in Taiwan that distributed JavaScript libraries, enabled compromise of more than 1,000 domains, and in some spearphishing variants used animal-rescue lures, Google Drive, and OneDrive for delivery.
