HACKERS USE SIGNAL QR CODES TO SPY ON MILITARY AND POLITICAL LEADERS

Summary from the TLDR InfoSec newsletter

Germany's BSI and BfV warned that state-backed hackers are targeting military leaders, diplomats, and journalists across Europe by abusing Signal's legitimate features — impersonating Signal Security Support to steal PINs and hijack accounts, or tricking targets into scanning QR codes that silently link attacker devices with access to 45 days of chat history. The campaigns rely entirely on social engineering rather than exploits, making them difficult to detect through traditional security tooling. Users should enable Registration Lock, audit linked devices regularly, and treat any unsolicited messages requesting verification codes as malicious.
