Security researchers have identified a new wave of attacks targeting users of older iOS devices with cryptocurrency wallets. The attacks exploit vulnerabilities in the Safari browser on outdated iPhones. Malicious websites, disguised as adult live streams, Tron energy stations, refund processes, and vulnerability alerts, can steal plaintext private keys if users unlock their wallet apps while these sites are open. Users are urged to prioritize system updates, especially those addressing security vulnerabilities, to protect their crypto assets. The researchers have not yet disclosed full details of the attack but emphasize the importance of keeping devices updated to prevent such exploits.
