Palo Alto Networks (PANW) - Get Palo Alto Networks, Inc. Reportpublished a list of the apps that used the incorrect program, known as XcodeGhost, including popular apps such as WeChat, Didi Kuaidi (the Chinese version of Uber), NetEase and Angry Birds 2. Part of the issue is that the developers, who seem to be located strictly in China, decided to use the incorrect program, which is used to create iOS and Mac apps simply because of time constraints.
If the developers had used Apple servers, which are localized in the U.S. it wouldn't have been an issue.
Despite this, it's a concern for some users who use these apps that the developers are not more diligent about their processes, though it seems unlikely this would affect iPhone and iPad sales given the steps Apple has taken to protect users privacy rights, as well as working with its partners to prevent malware. Palo Alto Networks found 39 apps were affected by the malicious code in total.
Shares of Apple were rising in pre-market trading on Monday, gaining 0.8% to $114.30.
For Apple to continue growing device sales, it's important that its relationship with developers continue to remain strong and untouched, given developers largely build for iOS first. Apple is thought to monetize its apps at 1.5 times the rate of Google (GOOG) - Get Alphabet Inc. Class C Report (GOOGL) - Get Alphabet Inc. Class A Report , according to research firm Gartner.
The App Store contains 1.5 million apps with more than 850 apps downloaded each second, according to Apple.
Since the App Store started in 2008, the Cupertino, Calif.-based company has paid out more than $30 billion to developers. In fiscal 2014 alone, Apple paid out more than $10 billion to developers, of which there are more than 380,000 developers in its paid developers' program, according to company reports.
