Researchers observed an attack against a cryptocurrency exchange in which a Trojan spread across both Windows and MacOS machines to steal information and possibly digital coins. Kaspersky Lab attributed the attack, dubbed Operation AppleJeus, to a threat group known as Lazarus, which has a history of targeting fintech firms, banks and related organizations. A similar variant of Fallchill is being developed for Linux-based systems as well, which means security teams may need to be vigilant of potential threats across a wider variety of platforms.”]
