A new cyberattack campaign targeting Brazil, codenamed “Boto Cor-de-Rosa,” highlights a critical security risk for the wider Web3 community. This campaign leverages the popular messaging application WhatsApp as a distribution vector for the Windows banking trojan known as Astaroth.
Cybersecurity researchers revealed that once installed, the malware automatically retrieves the victim’s WhatsApp contact list and sends malicious messages to each contact, facilitating rapid, worm-like spread.
While Web3 users often prioritize the security of DApps and smart contracts, neglecting conventional cyber threats impacting the devices (PCs and smartphones) where private keys or seed phrases might be handled is a a dangerous oversight. Social engineering threats, particularly those originating from seemingly trustworthy contacts via routine communication channels like WhatsApp, significantly lower user vigilance.
If such malware successfully infiltrates a system, the risk of credential theft, including wallet authentication data or information useful for session hijacking of Web3 services, escalates drastically. Protecting Web3 assets requires adhering to the fundamental security principle of never opening suspicious links or files, even when they appear to come from trusted contacts, across all devices and communication applications used.
