This creates a closed-system often referred to as “ security by obscurity”. When the initial infection attempt fails, the spyware supposedly prompts the user to grant relevant permissions so it can be deployed effectively.Īpple devices are generally considered more secure than their Android equivalents, but neither type of device is 100% secure.Īpple applies a high level of control to the code of its operating system, as well as apps offered through its app store. The spyware infects Android devices too, but isn’t as effective as it relies on a rooting technique that isn’t 100% reliable.

Most media reports on Pegasus relate to the compromise of Apple devices. This user is likely to remain completely unaware. In the case of spyware, once a device is unlocked, the perpetrator can deploy further software to secure remote access to the device’s data and functions. They are typically a combination of configuration changes and a “hack” of core elements of the operating system to run modified code. Rooting and jailbreaking both remove the security controls embedded in Android or iOS operating systems.

Similarly, a jailbreak can be deployed on Apple devices to allow the installation of apps not available on the Apple App Store, or to unlock the phone for use on alternative cellular networks. Usually, rooting on an Android device is done by the user to install applications and games from non-supported app stores, or re-enable a functionality that was disabled by the manufacturer. The aim is to seize full control of the mobile device’s operating system, either by rooting (on Android devices) or jailbreaking (on Apple iOS devices). Others use the more concerning “ zero-click” attack where vulnerabilities in the iMessage service in iPhones allows for infection by simply receiving a message, and no user interaction is required. If clicked, this link delivers malicious software that compromises the device. Some approaches may involve an SMS or iMessage that provides a link to a website. The Pegasus spyware can infect the phones of victims through a variety of mechanisms.
