Phishing via trusted-URL iframe content overlay
Published Dec 15, 2025 · Updated Dec 15, 2025
Address bar spoofing in LINE for iOS before 14.14 allows remote attackers to display malicious iframe content beneath a trusted URL. The in-app browser executes attacker-controlled JavaScript inside an iframe while its address bar continues to display the trusted URL, allowing overlaid content to impersonate that site. Exploitation requires user interaction with the crafted content; the reported consequence is phishing rather than direct account or device compromise.
