A few days ago Apple released the IOS 8.1.3 System Update, we people from the update log can not see what dongdong, is not wrong to repair, improve stability and performance of what is not related to our things. Yesterday, Apple officially released the itunes 12.1 Update, itunes from the 32-bit architecture to 64-bit architecture, the small part of the assumption that 32-bit upgrade to 64-bit, faster and more power, immediately updated. However, immediately with the PP Assistant to install pirated software, found that the PP assistant unexpectedly strike, 1:30 will not make clear, and then changed itools, 91 mobile phone assistant, XY assistant and fast with the Apple assistant try when unexpectedly all is so, so we can almost conclude, apple out of the killer.
Sure enough, all the big science and technology media in the morning have burst the material,. The previous iOS 81.3 system update fixes a "loophole", the so-called "mask" loophole, is the road assistants disguised as iTunes for everyone to install the application of the way. At the same time, ITunes 12.1 from 32 to the 64-bit architecture, so that all kinds of assistant invalidation, we can call it "all the road assistants have a corpse", "ban all assistants." So PC6 Apple net small make up here "gloat" ~ ~
Here by the way to help you popular science, how each assistant camouflage ITunes for IOS device applications.
The iOS system gives each application a secure area (sandbox), and one application does not have access to the data in the sandbox of other applications. Each application has a bundleid, a bogus application that has the same bundleid and has legal authority (typically repackaged by a legal enterprise certificate) can be installed on the phone to replace the original application and get all the permissions for the application.
The developer uses a valid enterprise certificate to repackage the application with the signature. Let the system think that this application is a large enterprise internal use of the application. or cracked FairPlay (DRM, Apple's copyright protection scheme). Through the use of ITunes on the computer to replace the user on the phone to buy information, so that the phone mistakenly think it is genuine users to buy. Nowadays, all kinds of "mobile assistants" in the market are basically used in this way.
Of course, this situation is only short-term, after a period of time, and other assistant reaction will be improved. Only with the Enterprise certificate has been repackaged to support the IOS 8.1.3 system, because most of the application has not been repackaged to follow up, so temporarily all the assistants can not do it! After a while repackaging the application will not be feasible. However, the current enterprise certificate by the various assistant abuse, resulting in Apple decided to withdraw the enterprise certificate sales, so that the child without a new certificate packaging the application of the assistant can not be installed through itunes.
So the question is, how do all the assistants live after Apple has massively revoked its corporate account? A word, although small knitting is very concerned about, but at present it seems helpless.
Finally, what do users do? First of all, please do not upgrade to IOS 8.1.3, has been upgraded does not matter, please do not update your iTunes to 12.1, both the Win version or the MAC version.
What about the pro who has been updated to ITunes 12.1? Unload load to install an old version chant! Small knitting Here is an itunes 12.0.1 for Win and itunes 12.0.1 for Mac.
