Trapdoor: new Android malware and ad‑fraud campaign affecting 455 apps

Colleagues, a cybersecurity alert: the Trapdoor campaign leverages Android apps for large‑scale ad fraud.

Briefly:
• HUMAN Satori — 455 malicious apps, 183 C2 domains; peak ~659M bid requests/day, >24M installs.
• Mechanics — 'utility' apps pull a second stage via fake updates; second‑stage apps launch hidden WebViews, use HTML5 cashout domains and execute click fraud.
• Uses attribution‑tool abuse, anti‑analysis and obfuscation; Google removed the identified apps.

Why it matters: ordinary installs are converted into a self‑funding fraud chain.

What measures do you consider priorities to protect the ecosystem and the ad market?
