tldr: Swing VPN is using its user base to DDOS sites using its users as a an attack botnet. new: Some people wrote me saying that the DDOS is not happening on ios devices. Just did a quick check and you guys are right. iOS app is using different way to do VPN and also does not do anything suspicious. I should appologize to you and to Appstore team for my lazy extrapolation without actually checking it.
