Casino powerhouse Caesars disclosed a significant data breach in September, preceding a similar incident at MGM later that month. The breach impacted over 41,000 patrons, primarily from the state of Maine, with cybercriminal group Scattered Spider identified as the perpetrators.

Caesars clarified that the breach primarily targeted its loyalty program, compromising personal information like names, driver's licenses, and ID card details of customers in Maine. 

Fortunately, no financial data was compromised. To mitigate the impact, Caesars is offering affected individuals complimentary two-year cybersecurity and identity fraud insurance. The exact tally of victims is still being determined, as per a filing with the Maine Attorney General's office. 

Caesars also mentioned in a letter to affected residents that efforts were made to delete the stolen data, although this outcome can't be guaranteed. Speculation suggests Caesars may have paid a reduced ransom amount of $15 million, down from an initial demand of $30 million.

Notably, it's been revealed that Caesars paid the ransom just days before Scattered Spider targeted MGM. This underscores the widely held belief that yielding to ransom demands only emboldens cybercriminals to strike again.

Caesars detailed the breach's origin, stating it was a result of a social engineering attack on an outsourced IT support vendor, leading to unauthorized network access on August 18, 2023, and data exfiltration from around August 23, 2023.

In response, Caesars is equipping affected Mainers with two years of identity theft protection through IDX, a third-party provider. This includes credit and dark web monitoring, as well as coverage of up to $1 million in case of identity theft.

While Caesars and MGM are prominent targets of Scattered Spider, cybersecurity firm Mandiant, a subsidiary of Google, has indicated that the group's recent ransomware campaign may have affected numerous industries beyond hospitality and entertainment, potentially numbering in the hundreds. This sequence of events serves as a stark reminder that capitulating to cybercriminal demands doesn't lead to a favourable outcome.
