Furthermore, thousands of customers reported receiving SMS alerts about unauthorized international transactions – in U.S. dollars and Brazilian real.

Clarifying their stance, a BookMyForex spokesperson told TechNadu that there was no data breach affecting BookMyForex systems or customer data. "YES Bank observed unusual volumes of false transaction attempts on YES BANK - BookMyForex Multi-Currency Prepaid Forex Cards which resulted in high number of declined transactions."

These transactions, they added, originated from a specific country. The bank promptly blocked transactions from the country that was identified as the source of all the malicious attempts.

"As a precautionary measure, cards involved in these attempted transactions were also proactively blocked. Customer balances remain fully secure." The company is currently monitoring the situation and working closely with the bank to take necessary steps.

They are also arranging complimentary replacement cards to ensure uninterrupted access to their forex balances, the spokesperson concluded.

Investigation and Response

Early indicators suggest the intrusion may have originated in a region of Brazil. However, definitive attribution is pending further forensic analysis. BookMyForex has also responded on X, stating there was no data breach.

The company's customer support channels are currently overwhelmed, reporting a threefold increase in traffic as distressed travelers attempt to resolve issues with their funds. Despite these internal upheavals, the primary website remains accessible.

Last week, the French Government disclosed a major breach of the national bank account registry.
