“How did this Chinese developer manage to sidestep Apple’s ultra-strict review process?” you may be wondering.

PDF Editor for Adobe Files slid into #11 on U.S. Chart Business. What does this mean? This malicious developer was generating significant revenue due to apps’ high visibility.

Finally, Kleber spotted the apps “abusively” downloading data that is completely irrelevant to their purpose, which could spell trouble for victims’ devices.
