# Apple Expands On-Device Lock Screen Alerts for Mercenary Spyware Targets

> Apple has expanded its mercenary spyware threat-notification program to display high-confidence targeting alerts directly on iPhone Lock Screens and in Settings, supplementing the existing email, iMessage, and Apple Account page notifications. Apple sent the first Lock Screen-based alerts on August 13, 2026 to targets in 110 countries, part of a program that has now notified individuals in over 150 countries since it launched in 2021.

## Description

Apple has for the first time delivered its mercenary spyware "threat notification" directly as a push alert on the iPhone Lock Screen and inside Settings (under "Apple Threat Notification"), rather than relying solely on email, iMessage, and an account.apple.com banner as it has since the program's 2021 launch. The August 13, 2026 round reached users in 110 countries; Apple says it has now notified individuals in over 150 countries in total since the program began. The alert text reads: "Apple detected a mercenary spyware attack targeted at your iPhone. There are actions you can take now to help protect your data and device." Apple describes these as high-confidence alerts based on its own internal threat-intelligence investigations and explicitly cites NSO Group's Pegasus as a historical example of the mercenary spyware class the program targets, while stating it does not attribute individual alerts to a specific spyware product or operator.

The program traces back to Apple's response to NSO Group's FORCEDENTRY exploit (CVE-2021-30860), a zero-click, zero-day iMessage exploit that abused an integer-overflow flaw in CoreGraphics/ImageIO JBIG2-encoded PDF processing to deliver Pegasus spyware without any user interaction, and which Citizen Lab captured on a Saudi activist's device in March 2021. Apple patched CVE-2021-30860 on September 13, 2021, and filed suit against NSO Group on November 23, 2021 seeking to permanently bar NSO from Apple's platform and devices; the threat-notification program dates to this same period. Apple's BlastDoor iMessage sandboxing mitigation (introduced in iOS 14) is understood to have driven NSO Group to develop FORCEDENTRY as a bypass after an earlier exploit (KISMET) was neutralized.

The underlying threat class is the commercial ("mercenary") spyware industry — vendors that develop and sell zero-click and one-click mobile intrusion capability to government customers, typically to surveil journalists, human-rights defenders, lawyers, political figures, diplomats, and civil-society organizers. Recent, publicly documented cases in this class include: (1) NSO Group's Pegasus used via the "PWNYOURHOME" zero-click exploit (crafted HomeKit NSKeyedArchive content processed by MessagesBlastDoorService) against former MEP Stelios Kouloglou on October 21, 2022 and again on March 6-7, 2023, while he served on the European Parliament's PEGA Committee investigating Pegasus abuse itself (Citizen Lab Report 194, published July 3, 2026); (2) Poland's ABW and SKW intelligence services' documented misuse of Pegasus against opposition figures, journalists, and prosecutors under the prior government (nearly 600 people targeted), which led to the December 2024 forced testimony of former ABW chief Piotr Pogonowski and the February 25, 2026 formal criminal charges against Pogonowski and former SKW chief Maciej Materka; (3) Paragon Solutions' Graphite spyware, delivered via a zero-click iMessage exploit (CVE-2025-43200, a logic flaw in processing a crafted photo/video shared via an iCloud Link, fixed across iOS/iPadOS/macOS/watchOS/visionOS on January-February 2025 patches), used against Italian journalists Francesco Cancellato and Ciro Pellegrino and activists Luca Casarini and Giuseppe Caccia in December 2024-February 2025, forensically confirmed by Citizen Lab on June 12, 2025 following an Apple threat notification on April 29, 2025; and (4) Intellexa Consortium's Predator spyware, whose developers and enablers (including Felix Bitzios, Andrea Gambazzi, Merom Harpaz, Panagiota Karaoli, Artemis Artemiou, and the BVI shell company Aliada Group Inc.) have been sanctioned multiple times by the US Treasury's Office of Foreign Assets Control for posing what Treasury called a significant threat to US national security.

Apple's stated primary mitigation for at-risk individuals is Lockdown Mode, an opt-in hardened configuration that aggressively restricts message attachments, complex web technologies (like just-in-time JavaScript compilation), unsolicited FaceTime calls, configuration profile installation, and wired connections when locked. Apple states it is not aware of any device with Lockdown Mode enabled having been successfully compromised by known mercenary spyware. Apple directs targeted individuals to Access Now's 24/7 Digital Security Helpline for free incident-response support and warns that phishing actors impersonate the legitimate threat-notification emails (sent from threat-notifications@email.apple.com) to harvest Apple ID credentials, so recipients should verify any alert by logging into account.apple.com directly rather than following links in the notification itself.

**Known false positives:**

- Threat-intel enrichment misclassification on shared CDN edge IPs; validate destination reputation before escalating

**Tuning notes:** Keep the mercenary-spyware C2 IOC lookup table refreshed from Citizen Lab / Amnesty Security Lab published indicators; because operators rotate through shared CDN IP space, corroborate any hit with device-side forensic indicators (e.g. TL-2026-2016-KQL-002) before treating as confirmed compromise.
