The Ritz London has launched an investigation into a potential data breach that affected its food and beverage reservation system. The information stolen in the breach seems to have been used by fraudsters to worm their way into the wallets of the hotel’s clients.

In a series of tweets shared over the weekend, the luxury hotel confirmed that it was made aware of the potential breach on August 12th, adding that the compromised data did not include any credit card or payment details. The hotel went on to notify all of its affected customers as well as the authorities about the breach while it investigates the incident further.

Even though, according to the hotel, no payment information was compromised, it seems that the cybercriminals behind the attack were after just that. According to the BBC, the miscreants leveraged the information obtained from the breach to pull off a very convincing social engineering attack. To make their ruse even more believable, they also spoofed the hotel's official number.

Posing as hotel staff, the scammers contacted clients who had made restaurant reservations at the Ritz, asking them to "confirm" their bookings by disclosing their payment card details. One of the victims speaking to the BBC confirmed that she was contacted a day before her reservation.

The fraudsters claimed that her card was declined and requested that she provide an alternative bank card. Once they were able to obtain the information, the ne’er-do-wells went on to rack up charges of over £1,000 (some US$1,300) at Argos, a catalog retailer.

When the suspicious transactions were flagged by the victim’s bank, the cybercriminals contacted her again. However, this time they pretended to be from her bank and tried to deceive her into disclosing the security code she'd received, stating they need it to cancel the transaction, while the code would have, in fact, authorized it.

The Ritz is just the most recent addition to the list of hotels that have fallen victim to similar incidents. Last summer, MGM Resorts suffered a breach that affected 142 million of its former guests. Hotel giant Marriott, meanwhile, was hacked twice in a span of two years.
