Pegasus Spyware Infections Proliferate Across iOS, Android Devices
The notorious spyware from Israel's NSO Group has been found targeting journalists, government officials, and corporate executives in multiple variants discovered in a threat scan of 2,500 mobile phones.
At a Glance
- Traditional endpoint security tools often don't spot Pegasus infections, as it exploits OS flaws and uses zero-click attacks.
- Regular updates to mobile OSes and proactive device-specific threat hunting are critical to preventing spyware infections.
- IT organizations must educate employees—especially those in high-risk roles—on mobile security best practices.
Researchers have discovered seven new Pegasus spyware infections targeting journalists, government officials, and corporate executives that started several years ago and span both iPhone and Android devices, demonstrating that the range of the notorious spyware may be even greater than once thought.
Researchers from iVerify discovered multiple devices compromised by Israeli company NSO Group's spyware via attacks initiated between 2021 and 2023 that affect Apple iPhone iOS versions 14, 15, and 16.6, as well as Android, they revealed in a blog post published on Dec. 4. The infections were discovered in May during a threat-hunting scan of 2,500 devices from iVerify users who opted in to the checks.
Specifically, the investigation uncovered multiple Pegasus variants in five unique malware types across iOS and Android. The researchers detected forensic artifacts in diagnostic data, shutdown logs, and crash logs found on the devices.
"Our investigation detected 2.5 infected devices per 1,000 scans — a rate significantly higher than any previously published reports," Matthias Frielingsdorf, Verify co-founder and iOS security researcher, wrote in the post. Each of the infections "represented a device that could have been silently monitored, its data compromised without the owner's knowledge," he wrote.
