The DarkSword exploit toolkit has compromised unpatched iPhones running iOS 18.4 to 18.7, draining over $5.57 million from more than 20 cryptocurrency wallets. Attackers leverage a zero-click vulnerability via malicious Safari pages, allowing them to extract sensitive information such as private keys and recovery phrases without user interaction. The exploit chain is built on six vulnerabilities documented by Google, which were reported to Apple but have not been publicly acknowledged or patched as of the latest updates. Security firms CertiK and Bitquery have linked the exploit to significant financial losses across various wallet applications, including MetaMask and Coinbase. The attack appears to have been ongoing since at least August 2026, with researchers still investigating the full scope and identifying the malicious websites used for delivery. Apple has released updates addressing these vulnerabilities, but many devices remain unpatched.
