This Wired report reviews Signal’s security posture and recounts two recent incidents: a Twilio phishing breach in 2022 that exposed SMS device-registration codes for roughly 1,900 Signal users and enabled at least one account takeover, and a mid‑February 2025 disclosure that Russian state‑backed actors weaponized Signal’s QR code feature by embedding JavaScript to link targets’ accounts to attacker devices; Signal issued a patch to mitigate the vulnerability.
