WhatsApp 'Eternidade' Trojan Self-Propagates Through Brazil

Eternidade is a two-part cybercrime campaign active in Brazil: a WhatsApp-spreading worm that selectively messages personal contacts and a Delphi-written trojan stealer that verifies victims (Brazilian Portuguese OS, not corporate/sandbox) and harvests banking and crypto credentials via overlays and exfiltration; the malware also includes resilient C2 mechanisms (email-driven C2 updates) and has been observed on roughly 10,000 infected systems.
