The FBI warns that ransomware threat actors are targeting casinos by exploiting vulnerabilities in vendor-controlled remote access and using legitimate system management tools. Small and tribal casinos have been targeted, with the Silent Ransom Group and Luna Moth carrying out phishing, data theft, and extortion attacks. The FBI advises implementing several mitigations such as offline encrypted backups, strong password policies, network segmentation, and monitoring for abnormal activity. Turning off unnecessary ports and protocols and restricting command-line and scripting activities are also recommended.
Key takeaways from the meeting notes:
1. The FBI has issued a warning about ransomware threat actors targeting casino servers and using legitimate system management tools to gain permissions on the network.
2. Third-party vendors and services are frequently exploited by ransomware gangs to breach casinos.
3. Small and tribal casinos have been targeted in ransomware attacks since 2022, encrypting servers and personally identifiable information.
4. The Silent Ransom Group (SRG) and Luna Moth are identified as threat actors involved in data theft and extortion attacks through callback-phishing.
5. SRG convinces victims to install a system management tool, which is then used for malicious purposes such as compromising files and exfiltrating data.
6. Mitigation advice recommended by the FBI includes implementing offline backups, remote access policies, strong password policies, multifactor authentication, network segmentation, monitoring for abnormal activity, secure RDP usage, and up-to-date software components.
7. Additional measures like disabling unnecessary ports and protocols, adding email banners for external messages, and restricting command-line and scripting activities are also advised.
