How to find iPhone is infected or not?

Yesterday, a research paper brought to light a new malware called WireLurker that is infecting iOS devices and Macs in China. The malware can infect both jailbroken and non-jailbroken devices when connected to an infected Mac through USB.

If you’re jailbroken, you can easily check if you’ve been infected with WireLurker by following these steps:

• Open iFile or SSH into your iOS device.
• Navigate to /Library/MobileSubstrate/DynamicLibraries
• If you see a file called sfbase.dylib then you likely are infected. If not, then you’re safe.
