A large-scale watering hole campaign attributed with moderate-to-high confidence to APT29 targets mobile devices by compromising legitimate websites, impersonating high-profile domains, and supply-chain compromising a Ukrainian analytics service. The campaign uses injected JavaScript to profile devices and deliver platform-specific n-day exploits against iOS and Android. Exploited vulnerabilities include multiple CVEs from 2024 to 2026. The final payloads exfiltrate sensitive data such as browser cookies, Wi-Fi passwords, and device information without establishing persistence, consistent with intelligence-gathering objectives.
