Apple has taken steps to stop WireLurker which can affect all iOS handsets not just jail broken ones by blocking known infected apps from downloading.
Here’s how WireLurker works: WireLurker monitors any iOS device connected via USB with an infected OS X computer and installs downloaded third-party applications or automatically generated malicious applications onto the device, regardless of whether it is jailbroken. This is the reason we call it “wire lurker”. Researchers have demonstrated similar methods to attack non-jailbroken devices before; however, this malware combines a number of techniques to successfully realize a new brand of threat to all iOS devices.
Apple has now blocked the apps from launching and infecting iOS devices. Here’s their statement on the matter.
“We are aware of malicious software available from a download site aimed at users in China, and we’ve blocked the identified apps to prevent them from launching. As always, we recommend that users download and install software from trusted sources,” said an Apple spokesperson.
