Pegasus Spyware Resurfaces with Newly Revealed Zero-Click Vulnerability

On September 13, The Citizen Lab revealed new research surrounding the Pegasus spyware campaign, presenting further details around their discovery of a zero-click vulnerability targeting Apple devices across the entire endpoint ecosystem.

In response to the disclosure, Apple has released security updates for all their devices from mobile to desktop. With Zimperium’s machine learning detection of exploits like Pegasus, Zimperium customers have been protected even before the disclosure.

The zero-click vulnerability, part of the vulnerabilities nicknamed ForcedEntry, takes advantage of how iMessage renders images, essentially opening up the file without the user interacting with the file. This is similar to Stagefright vulnerability discovered by Zimperium in 2015. Attackers can take advantage of this exploit to deliver a malicious PDF to target victims and remotely infect devices with spyware. The information from The Citizen Lab also shows this vector of attack has been active since February of this year.

This vulnerability, like others discovered throughout the mobile ecosystems, continues to highlight these always-connected devices as high-value targets, packed full of personal, private, and critical information. And as the lines continue to blur between mobile and traditional devices with information shared between systems in unison, it is as imperative as ever to have a robust, advanced security solution covering all devices.

Zimperium urges all users to update their Apple devices to the latest versions. Apple has released iOS 14.8, iPadOS 14.8, WatchOS 7.6.2, macOS Big Sur 11.6, and a security update for macOS Catalina to address this recent vulnerability (CVE-2021-30860).
