Russia-backed Hackers Crack Encrypted Messaging Apps

Google's Threat Intelligence Group revealed that Russia-backed hacking groups have developed techniques to compromise encrypted messaging services like Signal, WhatsApp, and Telegram, putting journalists, politicians, and activists at risk. Attacks involve exploiting Signal's 'linked devices' feature with malicious QR codes, accessing battlefield phones, and deploying phishing websites. These attacks are difficult to detect, potentially remaining unnoticed for extended periods. Signal has implemented security improvements, but users are urged to remain vigilant and avoid suspicious links.
