*Hackers Exploit Signal's Linked Devices Feature: Here's What You Need to Know* A recent report by Google's Threat Intelligence Group (GTIG) has uncovered a sophisticated hacking technique targeting Signal users. Hackers are exploiting Signal's linked devices feature to hijack accounts using malicious QR codes. *How the Attack Works* The attackers use malicious QR codes that, when scanned, link the victim's Signal account to an actor-controlled Signal instance. This allows the hackers to receive future messages sent to the victim's account in real-time. *The Threat Actors* Multiple Russia-aligned threat actors, including UNC5792, UNC4221, Sandworm, Turla, and UNC1151, have been identified as using this technique. These groups have been known to target individuals of interest, including Ukrainian military personnel. *Protect Yourself* To safeguard your Signal account, make sure to: 1. *Update to the latest version*: Signal has released updates for Android and iOS with hardened features to secure users against such phishing efforts. 2. *Be cautious of QR codes*: Avoid scanning QR codes from untrusted sources, as they may be malicious. 3. *Use strong security measures*: Enable two-factor authentication and use a secure password manager to protect your account. *The Bigger Picture* This attack highlights the growing threat to secure messaging applications. As hackers continue to evolve their tactics, it's essential to stay vigilant and take proactive measures to protect your online security. Stay safe, and stay informed! > ZoeCyber
