The Swing VPN app has been found to be using its user base as a botnet to conduct DDoS attacks on targeted websites, including Turkmenistan Airlines. The app, which has over 5 million installs on Android, sends requests to the targeted website every 10 seconds, potentially overwhelming the site's resources. The app's behavior is not limited to when it is in use, and it continues to send requests even when closed. This raises concerns about user privacy and the potential for malicious activity.
