A virus scan revealed that files in the OTA SDK are infected with the XcodeGhost malware. The infected files include:
QBLUE SDK\OTA IOS.zip
Here's some information on this malware:
This means that the application itself is compromised when installed on a device. It can be remotely controlled, and can access any data in the phone clipboard.
Short of rebuilding from sources on a known good Xcode environment, I don't know of any way to correct this problem. If you are able to provide a clean version, we would appreciate it.
Do you have any newer version of the app you could provide us a binary for? Alternatively, we could recompile from source if you could provide that to us.
