The United States government is offering a $10 million reward for information leading to the identification of Russian cyber groups involved in targeting Signal and WhatsApp accounts. These groups, UNC5792 and UNC4221, are linked to Russian intelligence services and are employing social engineering tactics to steal verification codes and backup recovery keys.
