Financial Impersonation Scam Tactics

Callers impersonating payment card networks rely on creating urgency and fear around account security or fraudulent activity. They may reference recent transactions you don't recognise or claim your card has been compromised. The goal is to extract card details, security codes, or one-time passwords that enable theft of funds.

The combination of language selection prompts and fake card company claims suggests this operation targets a broad audience using automated dialling systems. The NetSIP allocation means the number itself is legitimate infrastructure being misused for scamming purposes.
