The YiSpecter malware was publicly reported in early October 2015 and involves malicious iOS apps that abuse enterprise certificates and private APIs in the operating system to download and install other apps, display advertisements and upload device information to a remote server.
Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.
A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:
Check for the latest database updates
First check if your F-Secure security program is using the latest updates, then try scanning the file again.
Submit a sample
After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.
Note: If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.
Exclude a file from further scanning
If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.
Note: You need administrative rights to change the settings.
The YiSpecter malware comprises of four components that are signed by legitimate iOS app enterprise certificates, allowing them to be installed even non-jailbroken devices. The malware is reportedly spread through multiple vectors, including via hijacked ISP traffic and as part of a worm's payload, as well as the most common one of manual download and installation from an unauthorized app store (in the beginning, by pretending to be an 'adult content video player' app).
Once one component is installed on a device, it can abuse undocumented or private APIs found in iOS to download the other components from a command and control server. The malware can download and install other apps, hijack other apps to display advertisements, change the search engine settings and upload device details to the remote server.
Apple has issued a statement indicating that the malware is only able to affect iOS versions 8.3 and older. They have also revoked the enterprise certificates used and reiterated advice that users only download apps from the authorized app store. Thus far, reports of the malware have been from China and Taiwan. For more information about the malware, see:
