A researcher discovered that the Microsoft Bing Wallpaper app includes undocumented functionality that can locate and decrypt browser cookies (Chrome, Edge, and Firefox), modify Chrome extension preferences, intercept browser launches to promote Bing/Edge, and silently install Bing Visual Search. ESET classifies the app as a potentially unwanted application; Microsoft disputes that it decrypts "all" cookies. The findings indicate significant privacy and potential data-exfiltration risks for users who install the app.
