# Incident Report: OYO Hotel & Casino Las Vegas Data Breach
## Executive Summary
OYO Hotel & Casino Las Vegas experienced a cyberattack around January 8-11, 2025, leading to the confirmed compromise of personal information belonging to 4,741 individuals. The incident was discovered via internal notification regarding "unusual activity" on the shared network environment, prompting investigation and notification to affected parties.
## Incident Details
- Discovery Date: On or around January 11, 2025 (when the company was informed of unusual activity).
- Incident Date: Sometime between January 8 and January 11, 2025.
- Affected Organization: OYO Hotel & Casino Las Vegas (operated by Paragon Tropicana, Inc. (PTI), a subsidiary of Paragon Gaming).
- Sector: Hospitality/Gaming (Hotel and Casino).
- Geography: Las Vegas, Nevada, USA.
## Timeline of Events
### Initial Access
- Date/Time: On or around January 8, 2025 (start of the breach window).
- Vector: Not explicitly detailed, but involved unauthorized access leading to "unusual activity in the hotel and casino’s shared network environment."
- Details: Attack occurred over a three-day period.
### Lateral Movement
- Details: Not specified in the provided text, but exploitation of shared network environment implies movement occurred post-access.
### Data Exfiltration/Impact
- Date/Time: Ongoing during the attack window (Jan 8–11).
- Details: Personal information of more than 4,700 people was allegedly exposed.
### Detection & Response
- Date/Time: On or around January 11, 2025.
- Details: The company was informed of "unusual activity" on the shared network. Affected individuals were notified on October 9, 2025, according to documentation provided by Maine authorities.
## Attack Methodology
- Initial Access: Unknown (Implied network intrusion).
- Persistence: Not specified.
- Privilege Escalation: Not specified.
- Defense Evasion: Not specified.
- Credential Access: Not specified.
- Discovery: Not specified.
- Lateral Movement: Access to the "shared network environment" was achieved.
- Collection: Personal information was gathered.
- Exfiltration: Data was successfully exfiltrated or exposed.
- Impact: Unauthorized exposure/theft of personal information.
## Impact Assessment
- Financial: Not specified.
- Data Breach: Personal information of 4,741 individuals exposed.
- Operational: Potential disruption due to the initial incident discovery and subsequent remediation (unspecified).
- Reputational: Negative publicity resulting from the data breach disclosure.
## Indicators of Compromise
*No specific network or file indicators were detailed in the source material.*
## Response Actions
- Containment: The attack was discovered on Jan 11, implying containment began shortly after detection of unusual activity.
- Eradication: Not specified.
- Recovery: Not specified, though the response involved generating notification letters (dated prior to the October notification).
## Lessons Learned
- The reliance on a "shared network environment" may present a broader attack surface susceptible to unauthorized activity.
- Critical systems and user environments should have more robust, real-time detection mechanisms to identify "unusual activity" faster than the 7-month delay between the breach (January) and the public notification of affected Maine residents (October).
## Recommendations
- Immediately segment and isolate critical operational networks from shared or guest-facing environments.
- Enhance network monitoring and behavioral analytics to detect anomalous traffic patterns suggestive of lateral movement or data staging earlier than manual discovery.
- Review and enforce strict access controls across the shared network environment.
- Implement a formal incident response notification protocol to ensure swift communication with potentially affected parties across all relevant jurisdictions.
