Xcodeghost was just another analytics API to Apple, so they didn't care until they were alerted that it was added to apps without the consent of these developers. It was not 'malware' in the sense of enrolling users in a botnet or utilizing private APIs to record the screen without permission.

Lookout Security describes it as malware[2] and as malicious, as does Palo Alto Networks[3], Ars[4], Reuters[5] and The NY Times[6]. From here[1]: > Remote control security risks > XcodeGhost can be remotely controlled via commands sent by an attacker from a Command and control server through HTTP. This data is encrypted using the DES algorithm in ECB mode. Not only is this encryption mode known to be weak, the encryption keys can also be found using reverse engineering. An attacker could perform a man in the middle attack and transmit fake HTTP traffic to the device (to open a dialog box or open specific app for example). > Read and write from clipboard > XcodeGhost is also able, each time an infected app is launched, to store the data written in the iOS clipboard. The malware is also able to modify this data. This can be particularly dangerous if the user uses a password management app. > Hijack opening specific URLs > XcodeGhost is also able to open specific URLs when the infected app is launched. Since Apple iOS and OS X work with Inter-App Communication URL mechanism (e.g. 'whatsapp://', 'Facebook://', 'iTunes://'), the attacker can open any apps installed on the compromised phone or computer, in the case of an infected macOS application. Such mechanism could be harmful with password management apps or even on phishing websites. > Stealing user device information > When the infected app is launched, either by using an iPhone or the simulator inside Xcode, XcodeGhost will automatically collect device information.* > Then the malware will encrypt those data and send it to a command and control server.

  My point is that these are all things which analytics apis (which, mind you, are also arguably malware) at the time did as well - reading the clipboard was common as many operated their own internal clipboard proxy due to the slowness of pasting in older iOS versions. It's only called malware and not Facebook because it was injected into developers' apps without their knowledge. And the 'remotely controlled via commands' section is meaningless - apps can't JIT so such C&C was simply turning flags on-and-off to go on different code paths.
