We performed a security analysis of the LINE messenger in our latest paper, "LINE-Break: Cryptanalysis and Reverse Engineering of Letter Sealing", to appear in ACM ASIACCS’26. Joint work with Thomas Kingo Mogensen and Adam B. Hansen @csaudk.bsky.social. Full technical details at linebreak.info

We analyze its underlying end-to-end encryption (E2EE) protocol Letter Sealing v2 (LSv2) and show that a TLS Man-in-the-Middle (MitM) or malicious server can compromise integrity, authenticity, and confidentiality in various experimentally verified attacks.
