Just read Apple suffered its first major App Store attack. Check to make sure you are safe. https://www.yahoo.com/tech/s/malware-hits-chinese-apps-apple-app-store-cyber-191855815.html
It was mostly social apps that are prevalent in the AppStore, most of which I don't care about or simply never heard of.
Mostly Chinese apps but still a big list outside of that (http://nos.nl/l/2058965): - Lifesmart 1.0.44 - CamScanner - CamCard - SegmentFault 2.8 - OPlayer 2.1.05 - Mercury - WinZip - Musical.ly - PDFReader - guaji_gangtai en - Perfect365 - PDFReader Free - WhiteTile - IHexin - WinZip Standard - MoreLikers2 - CamScanner Lite - MobileTicket - iVMS-4500 - OPlayer Lite - QYER - golfsense - ting - installer - golfsensehd - Wallpapers10000 - CSMBP-AppStore - MSL108 - ChinaUnicom3.x - TinyDeal.com - snapgrab copy - iOBD2 - PocketScanner - CuteCUT - AmHexinForPad - SuperJewelsQuest2 - air2 - InstaFollower - CamScanner Pro - baba - WeLoop - DataMonitor - MSL070 - nice dev - immtdchs - OPlayer - FlappyCircle - BiaoQingBao - SaveSnap - WeChat - Guitar Master - jin - WinZip Sector - Quick Save - CamCard
I read somewhere that it is the browser. BTW this is a good summary about Xcode Ghost: http://www.macrumors.com/2015/09/20/xcodeghost-chinese-malware-faq/
I read on MacRumors and Ars Technica that Angry Birds 2 is on the list, but it's the Chinese version.
