Hungary's National Cybersecurity Institute warned that DarkSword, a publicly available spyware and exploit kit for Apple devices, is targeting iPhones and iPads running iOS 18.4 through 18.7 and corresponding iPadOS versions. The malware was described as easy to deploy after its code was released on a popular code-sharing platform, lowering the barrier for cyber-espionage activity. Once executed, DarkSword can steal contacts, messages, call history, authentication-related data, and other sensitive information, then exfiltrate it to attacker-controlled servers before deleting itself from the device to hinder detection.
New reporting says the operation has since grown into a broad malicious web infrastructure spanning 180 web properties and 27 hosts, using fake Apple sign-in pages, Apple-themed lures, and compromised websites to deliver a leaked six-vulnerability exploit chain and GHOSTBLADE data-theft modules. Researchers said successful compromise can expose keychain contents, iCloud data, Wi-Fi credentials, files, and Apple ID credentials, while operators rotate servers quickly and remove artifacts such as crash reports and RemoteLog.log to frustrate forensic analysis. Defenders were urged to apply Apple security updates, enable Lockdown Mode where patching is delayed, and monitor for recurring infrastructure fingerprints tied to the campaign.

3 events from the most recent confirmed update back to the earliest known activity.
As of July 30, 2026, Censys observed DarkSword infrastructure spanning 180 web properties and 27 hosts. The campaign used fake sign-in pages, Apple-themed lures, and compromised websites to deliver the exploit chain and deploy GHOSTBLADE data-theft modules.
The DarkSword malicious code was publicly released on a popular code-sharing platform, making the spyware broadly accessible and easy to deploy without significant iOS expertise.
Hungary's National Cybersecurity Institute warned that publicly available DarkSword spyware affects Apple devices running iOS 18.4 through 18.7 and iPadOS 18.4 through 18.7. The alert said the spyware can steal personal and authentication-related data, exfiltrate it to attacker-controlled servers, and self-delete after execution.

Researchers from **Google**, **iVerify**, and **Lookout** disclosed **DarkSword**, a sophisticated iPhone exploit chain used in compromised websites to silently infect visitors, with observed targeting focused on **Ukraine** and additional activity tied to **Saudi Arabia, Turkey, and Malaysia**. The campaign is linked to suspected Russian operators, including activity tracked as **UNC6353**, and appears to support both **espionage** and **financial theft**, including the theft of saved passwords, text messages, and cryptocurrency wallet data. Reporting also indicates DarkSword is the second major iOS exploit kit recently found in the wild after **Coruna**, reinforcing concerns that advanced mobile exploitation is becoming more broadly operationalized rather than reserved for narrowly targeted, bespoke use. Technical analysis shows DarkSword used multiple chained vulnerabilities to achieve full device compromise on older iOS versions, including JavaScriptCore bugs **`CVE-2025-31277`** and **`CVE-2025-43529`** for remote code execution, **`CVE-2026-20700`** as a `dyld` PAC bypass, and sandbox escapes that pivoted from **WebContent** to the **GPU process** and then to `mediaplaybackd`. The exploit chain relied on first compromising **WebKit** and then abusing **WebGPU/ANGLE**-related paths to escape Safari’s sandbox, and Apple patched the flaws across later iOS releases including **18.6**, **18.7.3**, **26.2**, and **26.3**. Researchers warned that a substantial installed base of devices running **iOS 18 or earlier** remained exposed at the time of disclosure, making DarkSword notable both for its technical sophistication and for the scale of potentially vulnerable iPhones.

Security researchers and media reports say the **DarkSword** iOS exploitation tool has moved from a targeted threat to a broader operational risk, with evidence that attackers can compromise hundreds of millions of iPhones and that exploit code has leaked publicly. Reporting from WIRED, Lookout, iVerify, and AppleInsider describes DarkSword as a powerful **zero-click** attack capability seen in the wild, raising concern that well-resourced espionage-style techniques are becoming more accessible to additional threat actors. Apple responded by issuing and then expanding protections, including rare **backported patches** for older supported devices to shield users who had not yet moved to newer iOS releases. iVerify said its investigations uncovered signs of zero-click mobile exploitation in the United States and warned that mass iOS attacks now represent a serious enterprise risk, while public reporting stressed that organizations and consumers should update affected iPhones immediately as leaked exploit code increases the likelihood of wider abuse.

Proofpoint and other researchers said the Russia-linked threat group **TA446**—also tracked as **Callisto**, **COLDRIVER**, **SEABORGIUM**, and **Star Blizzard**—used the leaked **DarkSword** iOS exploit kit in a targeted spear-phishing campaign aimed at compromising iPhone users. On March 26, the actor sent spoofed Atlantic Council "discussion invitation" emails from compromised accounts, redirecting selected recipients to DarkSword infrastructure that delivered the **GHOSTBLADE** dataminer, while non-iPhone users were reportedly shown a benign PDF decoy. Researchers said this is the first observed case of TA446 targeting Apple devices and **iCloud**-related access. The campaign was linked to TA446 through infrastructure overlaps, including VirusTotal samples referencing a TA446 second-stage domain and URLScan evidence showing a TA446-controlled domain serving DarkSword components. The operation also appeared broader than the group’s typical espionage activity, with targeting spanning government, think tanks, higher education, financial, and legal organizations. Apple separately warned users running older **iOS** and **iPadOS** versions to update because of active web-based attacks, while researchers cautioned that the leaked GitHub version of DarkSword could reduce the barrier to entry for advanced iPhone exploitation and help turn a nation-state capability into more widely available malware.
