Reusable 'DarkSword' iPhone exploit found in the wild, putting many iOS 18 devices at risk

Mar 18th 2026

Security teams disclosed a new iPhone exploit called DarkSword that has been deployed on infected websites to compromise iPhones running iOS 18, steal a wide range of personal data, and was left publicly accessible for reuse by other attackers.

  • Researchers at Google, iVerify and Lookout found DarkSword embedded in compromised websites that silently hack visiting iPhones.
  • DarkSword exploits most versions of iOS 18 but does not affect devices updated to the latest iOS 26 release.
  • The tool uses fileless smash-and-grab tactics to steal passwords, messages, photos, browser history, health data and cryptocurrency credentials without leaving a persistent implant.
  • Researchers say the full, documented DarkSword code was left accessible on infected sites, making it easy for other attackers to reuse.
  • The campaign was linked to a Russian state-associated actor and likely originates from a brokered market for exploits, increasing the risk of broader criminal reuse.
