'Exodus' Spyware Found Targeting Apple iOS Users

The surveillance tool dubbed 'Exodus' has been ported to the Apple iOS ecosystem. According to Threatpost, the spyware 'can exfiltrate contacts, take audio recordings and photos, track location data and more on mobile devices.' From the report: Earlier this month, word came that Google had booted a raft of Exodus-laden apps. According to Lookout Security, it turns out that iOS versions had become available outside the App Store, through phishing sites that imitate Italian and Turkmenistani mobile carriers. These are notable in that they abused the Apple Developer Enterprise program. According to Lookout and other research from Security Without Borders, the spyware appears to have been under development for at least five years. It's a three-stage affair, starting with a lightweight dropper that then fetches a large second-stage payload that contains multiple binaries with most of the spy goods housed within them. Finally, a third stage typically uses the Dirty COW exploit (CVE20165195) to obtain root privileges on a targeted device. In delving into the technical details, Lookout saw evidence of a fairly sophisticated operation, suggesting that it may have been initially marketed as a legitimate package for the government or law-enforcement sectors.

In order to spread the iOS app outside of the official App Store, the cybercriminals abused Apple's enterprise provisioning system, which allowed them to sign the apps using legitimate Apple certificates. Lookout's analysis found that the iOS variant is a bit cruder than its Android counterpart, and it lacks the ability to exploit device vulnerabilities. However, the apps were still able to use documented APIs to exfiltrate contacts, photos, videos and user-recorded audio recordings, device information and location data; and, it offered a way to perform remote audio recording, though this required push notifications and user interaction. The good news is that Apple has revoked the affected certificates for this particular crop of apps.
