LAS VEGAS (AP) — A persistent error message greeted Dulce Martinez on Monday as she tried to access her casino rewards account to book accommodations for an upcoming business trip.

Unsettled by the thought of what other information the hackers may have stolen, Martinez, a publicist from Los Angeles, said she signed up for a credit report monitoring program, which will cost her $20 monthly.

The situation entered its sixth day on Friday, with booking capabilities still down and MGM Resorts offering penalty-free room cancelations through Sept. 17.

Tony Anscombe, the chief security official with the San Diego-based cybersecurity company ESET, said it appears the invasions may have been carried out as a “socially engineered attack,” meaning the hackers used tactics like a phone call, text messages or phishing emails to breach the system.

“Security is only as good as the weakest link, and unfortunately, as in many cyberattacks, human behavior is the method used by cybercriminals to gain the access to a company’s crown jewels,” Anscombe said.

As the security break-ins left some Las Vegas casino floors deserted this week, a hacker group emerged online, claiming responsibility for the attack on Caesars Entertainment’s systems and saying it had asked the company to pay a $30 million ransom fee.
