Loading threat actor…
DarkSword is a threat actor or exploit-development entity associated with sophisticated multi-stage iOS Safari exploit chains. Its operations used JavaScriptCore remote-code-execution vulnerabilities to compromise devices across multiple iOS versions, followed by a dyld Pointer Authentication Code bypass, an escape from Safari WebContent into the GPU process, a further sandbox escape into a media service, and an XNU kernel privilege escalation. The exploit chain established physical and virtual memory read/write capabilities for post-exploitation. DarkSword has used distinct JavaScriptCore exploits tailored to targeted iOS versions. GHOSTBLADE, an iOS post-exploitation payload with modular library structures, was assessed as likely developed by DarkSword. Technical overlap has also been identified between DarkSword's renderer-stage exploitation and a separate iOS exploit chain delivered through compromised web themes; the overlap was assessed as a distinct variant and does not establish attribution of that broader campaign to DarkSword.

This exploit leverages CVE-2025-14174, a vulnerability in ANGLE where parameters were not sufficiently validated in a specific WebGL operation, leading to out-of-bounds memory operations in Safari's GPU process which the DarkSword developers use to execute arbitrary code within the GPU process.
For devices running versions of iOS prior to 18.6, DarkSword uses CVE-2025-31277, a JIT optimization/type confusion bug which was patched by Apple in iOS 18.6.
DarkSword uses another sandbox escape exploit, sbx1_main.js, which leverages CVE-2025-43510, a memory management vulnerability in XNU. This is a copy-on-write bug which is exploited to build arbitrary function call primitives in mediaplaybackd.
This uses CVE-2025-43520, a kernel-mode race condition in XNU's virtual filesystem (VFS) implementation, which can be exploited to build physical and virtual memory read/write primitives.
For devices running iOS 18.6-18.7, DarkSword uses CVE-2025-43529, a garbage collection bug in the Data Flow Graph (DFG) JIT layer of JavaScriptCore which was patched by Apple in iOS 18.7.3 and 26.2 after it was reported by GTIG.
