An iOS app called “Instaquotes Quotes Cards for Instagram” has been found to have a piece of Windows malware. However, it’s worth noting that many iOS users will never have a problem resulting from this because it has no effect on the iOS device itself. Also, users with a Mac will not notice any problems resulting from this piece of malicious code.
Users who organize their apps on Windows can be affected by the worm embedded in the app. The exact name of the worm is Worm.VB-900. The first people to report it assumed it was a false positive, but upon further review, it is a very real piece of Windows malware hidden away in an iOS app.
Apps from iTunes come in packages called .ipa files. These packages can contain any number of files that make the app work. When you sync your device to iTunes, the entire package is copied to your PC. If one of those files is malware, it will reside on your PC, and can cause problems.
Thankfully, this particular worm is quite old, and most antivirus software should have little issue removing it. Still, if it could happen with this app, another worm could certainly slip through the cracks again and it could be something worse.
The app has since been removed from the App Store, so you will not be able to download it until it is fixed. Let this serve as a warning that just because an app is meant for your iPhone, it could still contain harmful files for your PC or other device.
