Cybersecurity researchers have detailed a new campaign targeting Brazil, utilizing WhatsApp as a highly effective distribution vector for the Windows banking trojan, Astaroth. The campaign, dubbed ‘Boto Cor-de-Rosa’ by Acronis Threat Research Unit, demonstrates a potent blend of banking malware capability and auto-propagation.
The core mechanism involves the malware retrieving the victim’s WhatsApp contact list and automatically sending malicious messages to further contacts, effectively turning the victim’s account into a propagation engine. This social engineering tactic leverages inherent trust, maximizing infection rates.
While Astaroth focuses on traditional banking credentials, its successful deployment and rapid spread should serve as a crucial warning for the Web3 community. System compromise, whether on desktop or mobile, means that locally stored hot wallet private keys, seed phrases, and browser extension data—used for interacting with dApps—are immediately exposed. This incident underscores that the security perimeter for Web3 assets must encompass not just smart contract audits, but the rigorous security posture of the end-user devices. Vigilance against unsolicited or suspicious links, even those seemingly from familiar contacts, is paramount to protect digital assets.
