Malware for iOS

This is an incomplete draft list of known malware (including spyware, adware, trojans, viruses, and similar tools) that have targeted iOS, including jailbroken iOS. The dates are approximate dates when people discovered, publicized, or started discussing the tool.

The goal of this list is to aid better understanding of the risks of using iOS and jailbroken iOS - it's helpful to have as much accurate information as you can. If you're concerned about avoiding malware on your jailbroken device, check out this guide to making informed guesses about whether packages are reasonable to install.

Tools found in the wild

iKee and Duh (November 2009)

The Ikee-virus is a worm transmitted between jailbroken devices that have OpenSSH installed and haven't changed the default root password. It changes the lockscreen background to a photo of Rick Astley.

Two weeks later, the similar Duh worm spread, which was "much more serious than the original Ikee worm because it is not limited to infecting iPhone users in Australia, and communicates with an internet Control & Command centre, downloading new instructions - effectively turning your iPhone into part of a botnet."

"Find and Call" (July 2012)

Find and Call was an app on the App Store that automatically uploaded users' contact lists to the company's server, then spammed those contacts with a link to the app ("from" that user). This undisclosed, unwanted behavior makes the software fit the definition of a trojan. Articles: Kaspersky SecureList, Ars Technica, Sophos NakedSecurity.

FinSpy Mobile (August 2012)

FinFisher is a suite of commercial surveillance tools sold to governments, which have been used to target activists and other people. The suite includes spyware tools for many mobile operating systems, including iOS.

AdThief/Spad (March and August 2014)

AdThief (also called Spad) is malware targeting jailbroken iOS devices, which "tweaks a developer ID that’s intended to tell ad developers when their ads are either viewed or clicked and in turn, generate revenue. In the malware’s case, infected devices funnel those small payments away from the developers to the hacker", as explained by Kaspersky Threatpost. Security researchers estimated it had infected 75,000 devices.

Unflod (April 2014)

Unflod is a malicious piece of software targeting jailbroken iOS devices, which attempts to capture the user's Apple ID and password by using MobileSubstrate to hook into the SSLWrite function of Security.framework and then listening to data passed to it. Once the Apple ID and password are captured, it is sent to a Chinese IP address. It was inadvertently discovered by a Reddit user on April 17th, 2014.

Hacking Team tools (June 2014 and July 2015)

Hacking Team is a company that "sells offensive intrusion and surveillance capabilities to governments and law enforcement agencies", including iOS spyware tools. The iOS spyware tools appear designed for targeting/attacking specific people, not for broad surveillance of the public. Their main tool (Remote Control System) requires a jailbroken device, and they were researching options for non-jailbroken devices.

AppBuyer (September 2014)

AppBuyer, as discussed in this article by Palo Alto Networks, is "malware will connect to C&C server, download and execute malicious executable files, hook network APIs to steal user’s Apple ID and password and upload to the attacker’s server, and simulate Apple’s proprietary protocols to buy apps from the official App Store by victim’s identity." It targets jailbroken devices.

WireLurker and Masque Attack (November 2014)

As discussed at Misuse of enterprise and developer certificates: according to Palo Alto Networks, WireLurker is "a family of malware targeting both Mac OS and iOS systems for the past six months...It is the first in-the-wild malware to install third-party applications on non-jailbroken iOS devices through enterprise provisioning."

Masque Attacks are a related technique, also discussed by Palo Alto Networks: "an iOS app installed using enterprise/ad-hoc provisioning could replace another genuine app installed through the App Store, as long as both apps used the same bundle identifier."

Xsser mRAT (December 2014)

Xsser mRAT is a piece of malware that targets jailbroken devices. As described by Akamai: "The app is installed via a rogue repository on Cydia, the most popular third-party application store for jailbroken iPhones. Once the malicious bundle has been installed and executed, it gains persistence - preventing the user from deleting it. The mRAT then makes server-side checks and proceeds to steal data from the user's device and executes remote commands as directed by its command-and-control (C2) server."

XAgent (February 2015)

XAgent is a surveillance tool targeting specific people (such as people in governments, the military, and journalists) that can affect both non-jailbroken and jailbroken devices, as described in this article by Trend Micro. Also covered by PCWorld.

Lock Saver Free (July 2015)

Lock Saver Free is a free tweak, originally distributed on a default repository (removed from the repository after discovery of the problem), that installs an extra tweak that hooks into ad banners to insert its own ad identifier, presumably in order to give ad revenue to the author of the tweak instead of to the author of the website/app where the ad was found. Discussion on Reddit.

KeyRaider (August 2015)

KeyRaider, as discussed in this article by Palo Alto Networks, is a piece of malware for jailbroken devices that "steals Apple account usernames, passwords and device GUID by intercepting iTunes traffic on the device."

Tools developed as part of research

iSAM (June 2011)

iSAM is a malware tool developed by security researchers as a proof of concept. It affects both jailbroken and not-yet-jailbroken devices: it scans for jailbroken devices that have SSH running and the default root password, and it also includes a malicious version of the Star exploit (JailbreakMe 2.0) so it can jailbreak a device that isn't jailbroken yet.

Instastock (November 2011)

Charlie Miller, a security researcher, submitted an app to the App Store called Instastock to demonstrate "a flaw in Apple’s restrictions on code signing on iOS devices". The app was initially accepted and then pulled from the store.

Mactans (July 2013)

At the Black Hat 2013 conference, security researchers presented a tool called Mactans, a small device that looks like a charger but can insert malware if you plug an iOS device into it. The iOS device does not have to be jailbroken.
