A Day in the Life of a Prolific Voice Phishing Crew

Krebs On Security

Besieged by scammers seeking to phish user accounts over the telephone, Apple and Google frequently caution that they will never reach out unbidden to users this way. However, new details about the internal operations of a prolific voice phishing gang show the group routinely abuses legitimate services at Apple and Google to force a variety of outbound communications to their users, including emails, automated phone calls and system-level messages sent to all signed-in devices.

KrebsOnSecurity recently told the saga of a cryptocurrency investor named Tony who was robbed of more than $4.7 million in an elaborate voice phishing attack. In Tony’s ordeal, the crooks appear to have initially contacted him via Google Assistant, an AI-based service that can engage in two-way conversations. The phishers also abused legitimate Google services to send Tony an email from google.com, and to send a Google account recovery prompt to all of his signed-in devices.
