Adware.ModAd
Adware.ModAd is a Dr.Web detection for unofficial modified WhatsApp messenger builds (mods) that contain code responsible for loading target URLs and automatically opening advertising links while the messenger is in use, redirecting users to advertised websites. The provided content identifies these WhatsApp mods as among the most commonly detected adware programs in 2025. The infection vector described is installation of third-party WhatsApp modifications rather than official app-store versions. High-confidence behavior in the content is limited to ad-related redirection: opening links during messenger use and sending users to advertised sites. No specific threat actor, industry targeting, or concrete indicators of compromise are provided in the content.
