What is Virtual Card Fraud?
Virtual card fraud exploits card numbers that are issued digitally, i.e., single‑use or tokenized, either by account takeovers, issuer app compromise, or merchant data leaks. Attackers make test charges in small amounts, make payments through gift cards and instant goods, then vanish. Investigation is hard to catch up with because numbers are quickly rotated unless the signals are very tight.
Tell‑tales include micro‑auth waves by BIN corridor, device fingerprints matching numerous “unique” cardholders, and instant refunds to newly created instruments. Digital wallets introduce another fraud channel – token lifecycle errors, loose binding.
