About the Play Ransomware Group
The Play ransomware group, also known as PlayCrypt, has been active since June 2022. Initially targeting Latin America, the group has expanded its operations to North America, South America, and Europe. Play ransomware is known for targeting diverse industries, including IT, transportation, construction, government entities, and critical infrastructure. The group employs various methods to gain entry into networks, such as exploiting RDP servers, FortiOS vulnerabilities, and Microsoft Exchange vulnerabilities.
How the Attack Could Have Penetrated TEC's Systems
Play ransomware uses sophisticated techniques to infiltrate systems. They often exploit vulnerabilities in RDP servers and Microsoft Exchange, use valid VPN accounts, and employ tools like Mimikatz for privilege escalation. The group also uses custom tools to enumerate users and computers on compromised networks and copy files from the Volume Shadow Copy Service. Their ability to disable antimalware and monitoring solutions further aids in evading detection.
TEC's Vulnerabilities
TEC's extensive network and the critical nature of its services make it a prime target for ransomware attacks. The organization's reliance on interconnected systems and the vast amount of sensitive data it handles increase its vulnerability. The attack on TEC underscores the importance of robust cybersecurity measures, especially for entities involved in critical infrastructure.
