Coinbase Impersonation Reports for 1800 576 937
Two contributors have reported suspicious activity linked to 1800 576 937 (also written as 1800576937) impersonating Coinbase customer support. The reports indicate a coordinated phishing attempt combining voice calls and SMS messages designed to extract account access credentials and verification codes.

What Callers from 1800 576 937 Claim
