After learning about its Russian roots from Reuters, it removed Pushwoosh software from seven public-facing apps, citing security concerns. The U.S. Army said it had removed an app containing Pushwoosh code in March because of the same concerns. Pushwoosh code has been embedded into almost 8,000 apps in the Google and Apple app stores, according to Appfigures, an app intelligence website. "We haven't found any clear sign of deceptive or malicious intent in Pushwoosh's activity, which certainly doesn't diminish the risk of having app data leaking to Russia," he added. The CDC apps that contained Pushwoosh code included the agency's main app and others set up to share information on a wide range of health concerns.
