Censys Exposes DarkSword iOS Exploit Platform and Coruna Crypto Wallet Stealer

Censys has disclosed the inner workings of DarkSword, a commercial platform that sells remote access to iOS devices, along with its associated malware Coruna that targets cryptocurrency wallet recovery keys. The infrastructure was exposed between September 15 and 17, allowing researchers to analyze the full attack chain starting from a WebKit and JavaScriptCore exploit delivered through the browser. After escaping the Safari sandbox and reaching the kernel, the platform deploys three layers including a flag, controller, and main implant. Coruna then scans the device for BIP39-compliant seed phrases stored in photos and Apple Notes across 19 targeted wallet applications such as MetaMask, Phantom, Trust Wallet, Coinbase, Exodus, imToken, Bitpie, and BitKeep. The exposed server contained 11 victim recovery keys, 179 directories of extracted data, and 75 operator accounts, indicating a structured commercial operation with agent accounts, commissions, and device quotas. Confirmed infections affect devices running iOS 16.1 and 16.3.1, while Apple has extended patches to additional iOS 18 devices. Maintaining updated iOS versions remains the primary defense against this threat.
