Maybe I’m reading this wrong... But it says TOP 25 not all infected apps. So how many apps were impacted?
Apple has no control over apps distributed by private party.
In one story I read the Apple store had non-infected versions, while most others state that even the Apple store version was infected but those infected versions have now been removed from the store.
So the number of store apps was much lower than the 4000 infected apps claimed, but probably higher than 25 or even 100. Most infected apps outside of the Top 25 were so obscure that their downloads were measured in tens.
These are also only the top 25 apps that Apple removed from the Apple App store in China. . . and would not list any from the Jail-Broken App stores as Apple would not be concerned with them. Jail-Broken apps would have been created with Xcode or XcodeGhost as well. There are over a dozen third-party jail-broken app stores in China, with three major ones equivalent to Cydia in the West
As to total numbers, not the total ~4000 plus, seen on the C2 network, but probably under 50 actually on the Apple Store in China. I think the original report of 39 is probably close to correct. That is the number that was reported pulled from the Chinese Apple App Store and I've not seen a revised number for the Apple App Store.
The only revised numbers I've seen reported have been for what's being seen on C2. These ~4000 were apps that were analyzed moving data of the right type on the C2 network, which is the China segment of the Internet, not the Apps actually counted on the Apple App store.
It is logical to conclude that some of those were obviously from the Apple App Store. . . but the majority had to be from jail-broken stores: their titles had not ever existed on Apple's store.
